Description

[0001] The present invention relates to a kit consisting of devices and related methods. Background Art

[0002] The present invention belongs to the field of dentistry. In dentistry, complex designed devices and methods are used in order to:

[0003] -1) Realignment of the occlusal plane / bite surface, and / or

[0004] -2) before, simultaneously or after the beneficial displacement of teeth in the dental set, and / or

[0005] -3) Improve the appearance and shape of the teeth aesthetically, where aesthetic improvements usually also lead to functional improvements.

[0006] Dental examples include:

[0007] - Restoration of teeth,

[0008] - Use of implants,

[0009] - aesthetic correction and improvement of teeth,

[0010] - Orthodontic migration of the orientation and position of teeth in the maxilla and mandible.

[0011] The known set of devices is also referred to as an aligner, since it has an alignment function by which the teeth are oriented. However, if the alignment function is considered alone, this is disadvantageous from a dental point of view.

[0012] The object of the invention is therefore to provide a kit having functions beyond those previously used or having other functions. In particular, it should be possible to change the position of the occlusal plane, for example in a simple manner and / or in combination with an alignment function or a shifting function of a tooth or arch-shaped tooth element structure that can affect the entire dental arch. Also provided are related methods and related units, such as computer systems, computer programs, computer program products, related digital design data and related digital manufacturing data. Also provided are related treatment plans, in particular digital treatment plans.

[0013] With regard to the kit, this object is achieved by the kit as specified in claim 1. Improvements are specified in the dependent claims. With regard to the method and other units, the object is achieved by the patent subject matter of the corresponding appended claims. Improvements are also specified in the dependent claims.

[0014] The kit may include a device for supporting the migration of a person's occlusal plane. There may be at least two, five, ten, etc. devices or at least two, five, ten, etc. device pairs. The devices or device pairs may each include at least one jaw device. The at least one jaw device may each include or consist of an upper jaw device and / or a lower jaw device.

[0015] According to an embodiment, the device or the device pair is designed such that it is worn by the person according to a predetermined sequence, in particular according to an sequence determined in a treatment plan, in particular a digital treatment plan stored or storable on a computer.

[0016] According to an embodiment, the jaw device can extend from a receiving area for a left molar element via at least one receiving area for an anterior element or a canine element to a receiving area for a right molar element. Thus, the jaw device can include at least one first receiving area for a left molar, at least one second receiving area for an anterior or a canine, and at least one third receiving area for a right molar. The receiving areas can be arranged in a device element of the device, for example in a veneer element or a dental veneer, for example in a device element or a height element at the anterior position or at the canine position or in the molar region (molar or premolar).

[0017] According to an embodiment, the jaw device may define a plane.

[0018] According to an embodiment, in at least one device, at least one jaw device may comprise at least one height element on the first side.

[0019] According to an embodiment, at least two contact areas, in particular local contact areas, which can be parts of a larger contact area, for example a larger planar contact area, can be configured at different positions of the molar element at at least one height element. The two contact areas at the height element or the two local contact areas at the height element can have a distance of at least 10 mm or at least 15 mm from each other, for example a distance of less than 30 mm. The predetermination of at least two points of the plane can thus be given in a simple and / or defined manner. If the device is not placed on the opposing jaw or is in contact with a device on the opposing jaw, in particular a tooth replica or other areas of the opposing device, the contact area can contact the tooth element during occlusion.

[0020] Thus, there may be only one height element on the first side, which has, for example, two contact regions. Alternatively, there may be, for example, two or at least two height elements, each having at least one contact region, for example exactly one or more than one contact region.

[0021] According to an embodiment, at least one further contact region, in particular a local contact region, which may be part of a larger contact region, for example a larger planar contact region, may be formed on the second side of the at least one jaw device.

[0022] The contact area, in particular a local contact area, can be point-shaped or generally surface-shaped, in particular when flexibly plastically deformable or elastically deformable materials are used for the device or the device pair.

[0023] According to an embodiment, at least three contact areas may determine a plane. If there are more than three contact areas, these contact areas may lie in a plane. Alternatively, the plane may be determined by a suitable mathematical method, for example, by a minimum square error method or other similar methods, wherein other suitable mathematical metrics are minimized when determining the position of the plane. Instead of such a plane, two straight lines may also be involved first, which then define the plane.

[0024] According to an embodiment, the plane can be different from the person's starting occlusal plane or the person's current occlusal plane with respect to its inclination changed by at least one height element in the frontal section and / or sagittal section and / or with respect to its height position changed by at least one height element. For example, the frontal section can be perpendicular to the support plane on which the device is placed. The frontal section can be achieved by the same left / right tooth position, in particular in the molar area. The sagittal section can be parallel to the left / right center line of the device or to the support plane on which the device is located. When placed, the accommodation area for the tooth element points downward, i.e. facing the support plane. This applies to both mandibular devices and maxillary devices. The occlusal surface of the device is also suitable for being supported on a plane to define a frontal section and / or a sagittal section. In other variations, the frontal section / sagittal section can be defined by the patient's skull structure or a digital image of the skull structure, which is described in more detail below.

[0025] According to an embodiment, in at least another device of the kit, another inclination and / or another height position of the corresponding plane in the frontal section and / or sagittal section (e.g., the distance to the skull structure) can be adjusted by at least one additional height element, which differs in the adjusted height from the at least one height element.

[0026] According to an embodiment, in at least one device of the device, the at least one jaw device may include at least one contact area at the at least one height element. The at least one contact area may determine a plane, in particular a plane that may differ from the person's starting occlusal plane or the person's current occlusal plane with respect to the inclination changed by the height element. The position of the person's occlusal plane may be determined using mathematical methods.

[0027] The height element can adjust a distance of at least 1 mm (millimeters), at least 2 mm or at least 3 mm between the contact region and the occlusal surface of the underlying tooth element or between the contact region and a surface facing away from the contact region in the receiving region for the underlying tooth element. In the maxillary appliance, the tooth element can also be considered to be located below the contact region because it is covered by the contact region.

[0028] At least one height element or the height element can be adjusted to a height that is at least twice or at least three times the height at at least one receiving area of ​​at least one device for an anterior element or a canine element.

[0029] The plane may be a contact plane in which at least one contact area of ​​the height element and preferably further contact areas, such as contact areas at the height element or other elements or surfaces of a device, such as a mandibular device and / or a maxillary device, are located.

[0030] In the contact plane there can be densifications, ie height contours that resist sliding movements. However, a new bite plane can be learned by a person, for example during bite movements while eating or during unconscious bite movements outside of meals. Habituation effects can also lead to relearning.

[0031] According to another embodiment, at least one of the contact areas can be a sliding contact area and determine a sliding plane in which the jaw device can slide, so that the person is supported to learn a new occlusal plane, which can differ from the person's current occlusal plane, for example, with regard to its inclination or other parameters. Thus, in a plane determined by the at least one contact area, for example, the upper jaw device and the lower jaw device slide relative to each other. A rolling movement or a rolling-sliding movement can also replace the sliding movement. Flat sliding surfaces of the contact areas or sliding surfaces of different shapes can be used.

[0032] "Sliding" may mean that a lateral relative movement between the jaw device and the opposing dental arch or between the two jaw devices of the device is possible by at least a value of 1 mm (millimeters) to 5 mm or 1 mm to 3 mm. Thus, the minimum value may be, for example, 1 mm, 2 mm or 3 mm. The maximum value of the relative movement may be given by the anatomical structure of the jaw or by an additional slope that may form a stop.

[0033] Sliding can be performed in at least one spatial direction or in at least two spatial directions orthogonal to each other. In the case of two spatial directions, the above values ​​for sliding movement can apply to one of the two spatial directions (e.g. left-right or front-back) or to both spatial directions.

[0034] The deviation of the inclination angle in the frontal plane or in the sagittal plane can be, for example, 0.2 to 2 degrees or 0.5 to 1 degree. For example, the angle can be measured between two occlusal planes when they are superimposed on each other via the same reference point and compared. The angle can then be determined between the directions of the surface normals.

[0035] In another embodiment, the angle may be determined relative to a reference structure (eg, a sagittal plane of a person's head, etc.).

[0036] The deviation of the inclination can be indicated by a "tilt" of the occlusal plane, wherein, depending on the dental plan, a change in the distance from the occlusal reference point of the tooth to the occlusal plane can occur at at least one tooth position or at a plurality of tooth positions. For example, the distance can vary from 0.5 mm to 2 mm. At other tooth positions, the distance does not vary. At other tooth positions, the distance can vary in the opposite direction.

[0037] Additionally or alternatively, there may be a lateral shift of the occlusal plane in the current occlusal plane or in an occlusal plane with a change in inclination, for example from back to front, front to back, left to right or right to left, a rotation about the surface normal of the occlusal plane, etc. Additionally or alternatively, a parallel shift of the occlusal plane may also occur with a change in inclination, wherein a lateral shift may or may not be performed.

[0038] The plane (e.g. the sliding plane) can be determined by the contact areas, for example by one contact area, by at least two contact areas, by at least three contact areas, by at least four contact areas or by more than four contact areas. Thus, the position of the plane can be determined by at least three points. The size and / or number of the contact areas can simplify the determination of the sliding plane or its stable position in space.

[0039] The contact area can be flat, for example, in order to be able to better determine the position of the sliding plane. The flat surface of the contact area can extend in its lateral extent beyond the area usually formed by the cracks at the teeth / tooth elements. As a result, a so-called "densification" of the teeth or tooth elements of the upper and lower jaw can be successfully avoided, i.e. a lateral relative movement of the upper and lower jaw can be achieved. The lateral mobility makes it possible that the masticatory muscles and / or the human brain are stimulated to perform a lateral correction of the position of the upper and lower jaw, so that a new position of the occlusal plane, in particular a new inclination, is learned in the process. Marginal gaps between the jaw device and the teeth or tooth elements can support relearning, but are not required.

[0040] The contact area of ​​the maxillary device can be opposite to the contact area in the mandibular device. If the contact area is flat, even if there is a flat sliding surface only in the maxillary device at the sliding contact area or only in the mandibular device at the sliding contact area, "encryption" in the form of "bite" can be effectively prevented. Opposite to the flat sliding surface, there can be at least one sliding element (for example, only one sliding element, two sliding elements, three sliding elements or more than three sliding elements) that can slide on the plane. At least one sliding element can be, for example, a protrusion the size of a tooth crack (for example, a tooth crack itself or a replica of a tooth crack). Alternatively, the protrusion can also be smaller than the tooth crack, that is, the maximum lateral dimension can be, for example, less than 2 mm or less than 1 mm. Rounded protrusions can reduce friction. For example, when a cylinder or a wedge-shaped body contacts the sliding plane, a contact line can be formed. The cylinder or wedge-shaped body can extend in the lateral direction, for example, from the left molar to the right molar.

[0041] At least one sliding element can have as close to point contact or line contact as possible with the flat sliding surface of the contact area, which can reduce the mechanical friction between the two. On the other hand, in the case of approximately point contact or line contact, a material of a flat sliding surface or sliding element with a relatively high hardness can be used. If there is a small area of ​​contact, a softer material can be used to form the sliding surface and / or the contact element.

[0042] Generally, the position of the occlusal plane can be determined by three spatial angles of the surface normal of the occlusal plane or the tangents of the occlusal plane to the three coordinate axes of the Cartesian coordinate system and by three position coordinates about the three coordinate axes, ie, by a total of six parameters.

[0043] The inclination of the occlusal plane can thus be described, for example, by a spatial angle between the normal to the occlusal plane and two or three of the coordinate axes, wherein the normal can, if applicable, be extended in the direction of the coordinate origin and / or displaced parallel so that, for example, it intersects the corresponding relevant coordinate axis. The plane in which the spatial angle is then determined can be the plane that includes the surface normal and the coordinate axes. In this case, it can also be described as an angle of inclination or a degree of inclination.

[0044] The third spatial angle can describe a rotation / twist of the occlusal plane, for example, a rotation of the anterior-posterior "center line" of the dental arch, wherein the center line can pass exactly through the contact point of the anterior incisors or be located in the middle of the gap between these incisors. The two incisors can preferably be located in different quadrants of the dental plan. At least one coordinate axis can be projected into the occlusal plane to determine the third spatial angle in the occlusal plane, i.e. the angle between the projection of the coordinate axis and the center line. On the other hand, the center line can also be projected into a plane located in two of the three coordinate axes in order to then determine the third spatial angle there. In this case, it can also be spoken of as a rotation of the occlusal plane within the occlusal plane.

[0045] To determine the position of the occlusal plane, a reference point may be used at a tooth or tooth element, for example, the incisor point (center of contact or gap between the two anterior incisors in the mandible), and a corresponding point may be used in the maxilla. Alternatively, another reference point may be used at a tooth or tooth element to determine the position of the occlusal plane. Alternatively, the reference point may also be determined in other ways, for example, describing the geometry of the corresponding dental arch, such as a triangle, quadrilateral, pentagon, etc. Other methods may also be used to determine suitable reference points.

[0046] The set of devices may in particular be associated with the same person and / or directed to a uniform treatment goal of the teeth of that person.

[0047] Thus, the use of the proposed kit can make a decisive difference to known kits, since in known methods the occlusal plane is either not shifted at all or only after a shift of teeth / tooth elements, widening of the dental arch or other changes has been performed with the kit. This can lead to a lock-in when shifting teeth / tooth elements and / or to a person resisting repositioning once the device is no longer in use. For example, teeth constructed in the final medical body can be "bitten out" again, since the person has not yet learned where the new occlusal plane should be. This can be counteracted by the proposed kit, since the new position of the occlusal plane can first be adjusted and / or learned, and then the tooth position / dental arch can be shifted or the final medical body can be realized if applicable.

[0048] The relearning can be, in particular, neuromuscular relearning. The relearning can be achieved by habituation and / or by conscious training.

[0049] There may be at least 10 devices, at least 20 devices or at least 30 devices in the kit. There may be fewer than 100 devices in the kit. The exact number of devices may be given in the treatment plan and may depend, for example, on whether attachments are used or the pressure on their teeth that the person concerned can still accept.

[0050] The attachments that are attached to the teeth can play an important role in the success of the treatment. Attachments can be small fastening elements made of composite materials (i.e., tooth-like substances) that ensure that tooth movement can occur faster, easier, and more efficiently than teeth. Attachments can act as anchors that the aligners grasp to accomplish the movement. Attachments allow for precise application of the pressure required to move the teeth. In addition, attachments can enable complex movements, such as the rotation of teeth, and ensure that correction is made without unnecessary "intermediate movement." For example, attachments can be used to migrate a tooth out of the jaw.

[0051] In principle, treatment can also be performed without an attachment. In some misalignments, an attachment is not needed at all and / or is omitted on request or is arranged at a later point in time. Treatment without an attachment can result in the need for more splints to achieve the target alignment.

[0052] The device can remain in the mouth during eating so that the person / patient can also get used to the new position of the occlusal plane during eating. The person's teeth or the remaining tooth element structure can form at least one new occlusal structure together with the device, whose occlusal plane can correspond to the new position of the occlusal plane (e.g., the intermediate occlusal plane, the training occlusal plane or the planned final occlusal plane). After eating or at a normal time, the correspondingly worn device can be removed from the mouth in order to simply clean the teeth and / or the device, for example, a corresponding maxillary device and / or a corresponding mandibular device.

[0053] In another embodiment, the device or devices can be removed from the mouth while eating. The new position of the bite plane can then be learned between meals.

[0054] The tooth element structure may be formed from a plurality of tooth elements. The tooth elements may be natural teeth, such as untreated teeth, treated teeth (e.g. teeth comprising one or more fillings), partially crowned teeth, fully crowned teeth or artificial teeth, in particular teeth with artificial roots, implants, veneered teeth, post-crown teeth, worn or ground teeth, implant fastening devices (in particular post-like fastening devices), etc.

[0055] In all the embodiments described, there may be no further devices of the kit between the first device and the second device according to a predetermined order. On the other hand, in all the above embodiments, there may also be one or more further devices of the kit between the first device and the second device according to a predetermined order. The first device may be numbered 1 in the device numbering, but not necessarily. The second device may be numbered 2 in the device numbering, but not necessarily. However, the second device is located after the first device in the order. Therefore, the first device may have a number n, where n may be a natural number greater than 1. The second device may have a number n+1 or a number n+m, where m is also a natural number, in particular greater than zero, for example also greater than 1.

[0056] In particular, a permanent shift of the occlusal plane can be prepared, which shift can, for example, differ from a shift that is only temporary, for example, to achieve a specific tooth shift. In particular, the permanent occlusal plane can be fixedly adjusted in the final treatment, for example, by using table tops (height structure) and / or one or more inlays (with ground tooth surfaces), one or more crowns, bridges, implants, in particular combinations of the aforementioned elements. Blockage of multiple teeth is avoided as much as possible in order to prevent adverse effects, such as damage to the fine retaining fibers (through fibers) of the teeth.

[0057] Thus, the position of the occlusal plane can be constructed up to the last aligner, for example directly by asymptotic approach or indirectly by overshoot, as will be explained in detail below.

[0058] The final height position of the occlusal plane or the final position of the occlusal plane can be a physiologically suitable position of the occlusal plane. This final position can differ from a non-permanent position of the occlusal plane, which can be used, for example, for "positioning activities" for the relocation of individual teeth or for temporary, in particular excessive, neural reprogramming. The final position or target position of the occlusal plane can be adjusted to a new axis position relative to the articular axis of the occlusal joint.

[0059] In particular, the following variations are possible:

[0060] a) Only the inclination of the occlusal plane in the frontal plane is changed, in particular in preparation for a permanent change, ie, for example, neither the inclination of the occlusal plane in the sagittal plane nor the height position of the occlusal plane is changed.

[0061] - b) Only the inclination of the occlusal plane in the sagittal plane is changed, in particular in preparation for a permanent change, ie, for example, neither the inclination of the occlusal plane in the frontal plane nor the height position of the occlusal plane is changed.

[0062] -c) Change of the inclination of the occlusal plane in the sagittal and frontal planes, especially in preparation for permanent changes, in which the height position of the occlusal plane is not changed.

[0063] -d) Only the height position in the occlusal plane is changed in order to prepare for a permanent change in the height position. The inclination of the occlusal plane in the sagittal or frontal plane can remain unchanged, i.e. not change.

[0064] -e) There may be a combination of the above changes, for example there may be changes in all three parameters.

[0065] f) Further changes may be present, ie for example a rotation of the occlusal plane within the occlusal plane itself, ie a twisting about the axis of the surface normal of the occlusal plane, in particular without or in combination with other changes of the abovementioned parameters.

[0066] The contact area or contact point can be individual, can be included in the contact line, or can be included in the contact surface. The three contact areas or contact points can be arranged so that they form a triangle, i.e. all three contact areas are not on a straight line. Thus, the plane can be simply and precisely defined or predetermined by the three contact areas, in particular by at least one local contact area.

[0067] The height element of the kit for shifting the occlusal plane can be designed so as to prepare for a permanent shift of the occlusal plane. Preparation for a permanent shift can be achieved by direct approaching the target occlusal plane, wherein the height adjusted by the height element is increased or decreased progressively. Direct approach can be performed faster than indirect shifting, for example in case fewer devices or fewer pairs of devices of the kit are used. However, medical conditions may oppose the use of direct preparation.

[0068] Alternatively, the target occlusal plane can be approached indirectly, wherein the height adjusted by at least one height element is gradually increased first and then reduced in the opposite direction or first reduced and then increased in the opposite direction. This can better take into account medical conditions. Alternatively or additionally, neurophysiological relearning can be promoted when an overshoot is first achieved and then this overshoot is withdrawn. This "overshoot" can also lead to a stretching of the jaw joint, which promotes relearning or makes relearning possible in certain situations and / or for certain people.

[0069] According to an embodiment, in at least two devices or in at least two device pairs, the jaw devices (e.g. the upper jaw device and / or the lower jaw device) each comprise at least one (local) contact area (e.g. the sliding contact area) at at least one height element. In a first device or a first device pair of the at least two devices / device pairs, there may be a first receiving area for a tooth or a tooth element (e.g. a tooth element structure for the upper jaw or the lower jaw). The first receiving area may be arranged relative to a first plane (e.g. the first sliding plane) of the first device or the first device pair according to a first arrangement.

[0070] According to an embodiment, in a second device or a second device pair of at least two devices / device pairs, a second receiving area for a tooth / tooth element or tooth element structure of the upper or lower jaw can be arranged according to a second arrangement different from the first arrangement relative to a second plane (e.g. a sliding plane) of the second device or the second device pair. By means of the second arrangement different from the first arrangement, the occlusal plane can be adjusted, in particular with respect to its inclination. In particular in the case of a change in the inclination or height position of the occlusal plane / sliding plane, a relearning of the position of the occlusal plane of the person (in particular a neuromuscular relearning) can be achieved from an occlusal plane associated with the first arrangement (e.g. the first plane) to an occlusal plane associated with the second arrangement (e.g. which can be located in the second plane).

[0071] According to another embodiment, the following sliding surfaces may be present:

[0072] - first upper right sliding surface, and / or

[0073] - a second upper left sliding surface, and / or

[0074] - the third lower left sliding surface, and / or

[0075] -Fourth lower right sliding surface.

[0076] The first sliding contact may be formed by the first sliding surface and the fourth sliding surface. The second sliding contact may be formed by the second sliding surface and the third sliding surface. The first sliding contact area and the second sliding contact area may be arranged in a sliding plane. The sliding surface may be flat.

[0077] Instead of an occlusal plane or a flat or planar sliding surface, a curved surface (eg a sliding surface) can also be defined, provided that it is ensured that this surface contributes to the therapeutic effect and / or a relative movement is possible, for example a surface comprising a curve in the Spee-Kurve.

[0078] The occlusal plane can be determined, for example, by a metal plate, which is placed between the teeth, for example, before the start of treatment in order to determine the starting occlusal plane. This means that the metal plate can determine the occlusal plane when the occlusal surfaces of the teeth of the upper jaw are in mechanical contact with the occlusal surfaces of the teeth of the lower jaw. As mentioned above, the occlusal structure can also be supplemented by a device, in particular by a part of the device arranged at the occlusal surface of the tooth / tooth element. The occlusal plane migrated by the device during the treatment with the device of the kit can then be permanently realized in the final medical body at the end of the treatment, i.e. in particular in the form of being firmly anchored at the teeth, wherein existing or still existing teeth can be used as much as possible.

[0079] According to an embodiment, in a third device of the at least two devices / device pairs, at least one jaw device comprises at least one contact area at at least one height element. In the third device of the at least two devices / device pairs or the third device pair, a third receiving area for a tooth / tooth element or tooth element structure of the upper or lower jaw can be arranged relative to a third plane (e.g. a third sliding plane) of the third device pair according to a third arrangement. The third arrangement can be different from the first arrangement and / or different from the second arrangement. By means of the third arrangement, a change in the position of the occlusal plane of the person to a third occlusal plane (a third plane in or at the third device), which is for example located in the third plane and is different from the first occlusal plane (a first plane in or at the first device) and / or different from the second occlusal plane (a second plane in or at the second device), in particular a change in the inclination of the occlusal plane to the third occlusal plane and / or other parameters can be achieved. By means of the third arrangement, a neuromuscular relearning of the position of the occlusal plane of the person to the third occlusal plane, which can be different from the first occlusal plane and / or the second occlusal plane, can be preferably achieved.

[0080] The change of the second arrangement compared to the first arrangement can be realized in the same direction or with the same trend as the change of the third arrangement compared to the second arrangement. The same direction or the same trend can mean, for example, that the angle between the corresponding plane in the frontal plane (for example the sliding plane) and the occlusal plane is continuously increased or decreased. Additionally or alternatively, the angle between the corresponding plane in the sagittal plane (for example the sliding plane) and the occlusal plane can be continuously increased or decreased. Furthermore, additionally or alternatively, the distance between the corresponding plane and the occlusal plane can also be continuously increased or decreased. Additionally or alternatively, the height position of the plane, in particular the height position of the occlusal plane, can be changed.

[0081] A technical effect of an embodiment may be that changes can be performed in multiple steps, for example in order to make a person feel better, ie increase acceptance of the device and / or reduce pain.

[0082] The third device or the third device pair can have the number "3" according to the sequence, but this is not mandatory. The third device or the third device pair can be placed after the second device pair / devices and / or also after the first device pair / devices according to the sequence (e.g. the sequence preset in the treatment plan). The three devices / device pairs can be placed directly one after the other in the sequence. In addition, there can be further devices / device pairs between the three devices / devices, in which, for example, the position of the occlusal plane is maintained.

[0083] According to an embodiment, in particular according to an alternative embodiment, in a third device of the at least two devices / device pairs, at least one jaw device comprises at least one contact area at at least one height element. In the third device of the at least two device pairs or the third device pair, a third receiving area for a tooth / tooth element or tooth element structure of the upper or lower jaw can be arranged relative to the third device or relative to a third plane (e.g. a sliding plane) of the third device pair according to a third arrangement. The third arrangement can be different from the second arrangement. By means of the third arrangement, a change in the position of the occlusal plane of the person to a third occlusal plane (third plane) different from the first occlusal plane (first plane) and / or different from the second occlusal plane (second plane) can be achieved, in particular a change in the inclination of the occlusal plane to a third occlusal plane (third plane) different from the first occlusal plane (first plane) and / or different from the second occlusal plane (second plane) can be achieved. By means of the third arrangement, a neuromuscular relearning of the occlusal plane of the person to a position of the third occlusal plane which can be different from the first occlusal plane and / or different from the second occlusal plane can be preferably achieved. The change of the second arrangement compared to the first arrangement may be effected in an opposite direction or with an opposite trend to the change of the third arrangement compared to the second arrangement.

[0084] Thus, the third arrangement can be like the first arrangement. The third arrangement can be different from the first arrangement. The three devices / device pairs can again be placed directly one after the other according to the sequence. Alternatively, there can be other devices / device pairs between the three devices / devices, wherein for example the position of the occlusal plane is maintained.

[0085] "Opposite directions" or "opposite trends" may mean, for example, that the angle between the corresponding plane in the frontal plane (e.g., the sliding plane) and the occlusal plane first increases and then decreases or that the angle first decreases and then increases. Additionally or alternatively, the angle between the corresponding plane in the sagittal plane (e.g., the sliding plane) and the occlusal plane may first increase and then decrease or first decrease and then increase. Additionally or alternatively, the distance between the corresponding plane (e.g., the sliding plane) and the occlusal plane may also first increase and then decrease or first decrease and then increase.

[0086] For example, depending on the sequence, further devices of the kit can be located between them, ie between the second device and the third device, in particular with an identical arrangement of the respective receiving areas to the respective sliding planes (ie in particular with regard to the possibility of relearning the occlusal plane).

[0087] The technical effect of the embodiment may be that an "overshoot" is achieved. For example, during the learning process, an occlusal plane may be provided as a learning target, which is significantly different from the final desired occlusal plane than is achieved later. Due to the large difference, relearning may be simplified. However, there may also be other reasons for such an "overshoot", for example in order to better resolve blocking, i.e., to make unlocking easier, for example.

[0088] In this embodiment, the third device pair can still have the number "3" according to the sequence, but it is not necessary. The third device pair can be placed after the second device or second device pair according to the sequence (e.g., the sequence predetermined in the treatment plan) and / or also after the first device or first device pair.

[0089] According to an embodiment, in a fourth arrangement of the device, at least one jaw device may comprise at least one contact area at at least one height element. In a fourth arrangement or a fourth arrangement pair of at least two device pairs, a fourth receiving area for a tooth / tooth element or tooth element structure of the upper or lower jaw may be arranged according to a fourth arrangement relative to a fourth sliding plane of the fourth arrangement or the fourth arrangement pair.

[0090] The fourth arrangement may be different from the third arrangement. The fourth arrangement may enable a preferred neuromuscular relearning of the person's occlusal plane to a position of a fourth occlusal plane that may be different from the first occlusal plane and / or different from the second occlusal plane, in particular a preferred neuromuscular relearning of the person's occlusal plane with respect to its inclination and / or with respect to other position parameters of the occlusal plane to a position of a fourth occlusal plane that may be different from the first occlusal plane and / or different from the second occlusal plane. Thus, for example, the fourth arrangement may enable a preferred neuromuscular relearning of the person's occlusal plane to a position of a fourth occlusal plane that may be different from the first occlusal plane and / or different from the second occlusal plane. The change of the third arrangement compared to the second arrangement may be achieved in a direction opposite to the change of the fourth arrangement compared to the third arrangement or with an opposite trend.

[0091] The technical effect of this embodiment can realize the "swing" of "coming" and "back" and "coming" again. Fig.19 This is described in more detail. Thus, more freedom can be created in the design of the device and in the performance of dental treatment. For example, space can also be created for further migration of teeth or at least one dental arch.

[0092] In this embodiment, the fourth device pair can still have the number "4" according to the sequence, but this is not mandatory. The fourth device pair can be placed after the third device or the third device pair according to the sequence (e.g. the sequence predetermined in the treatment plan) and / or also after the first device / device pair and / or after the second device / device pair. The four devices / device pairs can be placed directly one after the other in the sequence. Alternatively, there can be further devices / device pairs between the four devices / devices, wherein, for example, the position of the occlusal plane is maintained.

[0093] According to an embodiment, the at least one height element can extend over at least two receiving areas or at least three receiving areas for at least one molar element, respectively, or have a length of 15 mm (millimeters) to 30 mm. Thus, the position of the plane can be determined robustly and / or simply, in particular primarily or decisively, by the at least one height element.

[0094] According to an embodiment, the at least one height element can have a height of at least 2 mm, at least 3 mm or at least 4 mm, in particular a height of less than 5 mm or less than 7 mm, in at least one of the at least two areas or at least three receiving areas. Thus, the position of the plane can be determined robustly and / or simply, in particular primarily or decisively by the at least one height element.

[0095] According to an embodiment, the at least one height element determines the height between the at least one contact area and a face of the receiving area facing away from the at least one contact area. According to an embodiment, at the face, the occlusal face of the dental element covered by the height element can be located at the same dental element position as the at least one contact area. The face can also be opposite the occlusal face, for example when an occlusal gap is predefined.

[0096] The distance defined by the height element may be 2 mm to 6 mm or 2.5 mm to 5 mm.

[0097] According to an embodiment, no height elements causing a height difference of, for example, more than 1 mm may be arranged on the second side of at least one device. Thus, there may be devices with a strong left / right asymmetry, which may be necessary for a specific treatment.

[0098] According to an embodiment, the at least one height element determines the height between the at least one contact area and a face of the receiving area facing away from the at least one contact area. According to an embodiment, at this face, the occlusal face of the dental element covered by the height element can be located at the same dental element position as the at least one contact area. This face can also lie opposite the occlusal face, for example when an occlusal gap is predefined.

[0099] Depending on the embodiment, the distance may be 2 mm to 6 mm or 2.5 mm to 5 mm.

[0100] According to an embodiment, at least one height element may be arranged on the second side of at least one device, which causes a height difference of, for example, more than 1 mm, more than 2 mm or more than 3 mm. The height difference may, for example, be less than 4 mm or less than 5 mm. Thus, there may be devices without or with relatively small left / right asymmetry.

[0101] According to another embodiment, at least one height element on the first side can be adjusted to a different height than at least one height element on the other side, preferably to a height difference of at least 0.5 mm, at least 1 mm or at least 1.5 mm. The adjusted height difference can be less than 5 mm (millimeters), less than 4 mm, less than 3 mm or less than 2 mm.

[0102] According to an embodiment, at least one height element can be adjusted to a height that is at least two times or at least three times the height of at least one device on at least one receiving area for anterior elements or canine elements. Thus, in these areas, where the height difference may be aesthetically and / or functionally undesirable or obstructive, the height difference achieved by the height element may be noticeable compared to other areas of the device. The difference may be less than 10 times or less than 7 times.

[0103] According to an embodiment, in which at least one height element is free of locking means, the locking means are designed to enter into a mechanical or magnetic coupling with relative locking. Such locking can be used to push the mandible forward or backward relative to the maxilla. Recesses and / or protrusions can be used as locking, which exceed the normal height of the crack. Thus, the recesses and / or protrusions on the occlusal surface of the height element can have a height of only, for example, less than 1 mm, to avoid locking.

[0104] Alternatively, at least one height element can also have such a locking device.

[0105] According to an embodiment, at least one height element adjusts a first height at a first tooth position and a second height at a second tooth position. The first height may be at least 0.25 mm, at least 0.5 mm or at least 1.0 mm greater than the second height. Thus, a decreasing or increasing height from or towards the front may be achieved.

[0106] This can apply in particular if the height element extends over at least two receiving areas or at least three receiving areas for the molar elements or has a length of at least 20 mm to 30 mm.

[0107] The variation in height within the height element may be less than 3 mm or less than 2 mm.The variation in height within the height element may take into account the anatomical structure of the mandible and / or mandibular joint.

[0108] Two regression lines or two regression planes may be used on the occlusal surface, namely the occlusal surface of the height element and the surface opposite thereto, at which or facing which the occlusal surface of the tooth or other dental element may be located.

[0109] Minimizing the distance and / or the sum of squared errors or other suitable mathematical measures can be used to determine the position of a line or plane. In this case, the Gaussian method of the minimum sum of squared errors is also mentioned. Other suitable mathematical measures other than the squared errors can also be used.

[0110] According to another embodiment, the height element may determine the distance between the contact area and the occlusal surface of the tooth element covered by the height element. The distance may be 2 mm to 6 mm or 2.5 mm to 5 mm. The distance may be less than 8 mm or less than 6 mm.

[0111] The elevation element may be solid in its interior or have at least one cavity, for example a honeycomb or otherwise supported cavity, located between the occlusal surface of the dental element and the contact area. The cavity may be connected to the receiving area of ​​the dental element, which may simplify the manufacture. However, the cavity may also be separated from the adjacent or adjoining receiving area, for example by a closing step during the manufacture.

[0112] The height element can be designed as an overlay and, for example, imitate a tooth crack or have the shape of another occlusal surface.

[0113] The height element can extend over at least one tooth element, for example over exactly one tooth element, at least two tooth elements or at least three tooth elements of a dental arch (arc-shaped tooth element structure) or corresponding receiving areas for these tooth elements.

[0114] When viewed from the patient, with respect to the same jaw, there is an asymmetry of the height elements on the right side compared to the left side, for example, there are height elements only on one side (height, for example, greater than 1 mm), and no height elements on the other side. In another embodiment, there may be height elements with different heights (for example, greater than 1 mm) on the left and right. The height difference may be greater than 1 mm, for example.

[0115] A plurality of height elements or at least one height element may, for example, be present only in the mandibular appliance and not in the maxillary appliance, or only in the maxillary appliance and not in the mandibular appliance. On the other hand, the height element may also be present in both the mandibular appliance and the maxillary appliance.

[0116] According to another embodiment, the new occlusal plane can differ from the person's starting occlusal plane or the person's current occlusal plane with respect to its position in the up-down direction and / or with respect to its position in the left-right direction. Thus, a change in inclination and a height shift can be achieved cumulatively or alternatively. Thus, the occlusal plane can be migrated in a medically required direction. The migration of the occlusal plane can be supported by an optional sliding function, which promotes relearning, in particular neuromuscular relearning.

[0117] The position in the up-down direction may be changed by a value such as 0.5 mm to 3 mm or 1 mm to 3 mm, for example.

[0118] The position may be changed in the left-right direction by, for example, a value of 0.5 mm to 3 mm or 1 mm to 3 mm.

[0119] For example, in addition or alternatively, with respect to other changes, i.e., for example, when the position of the occlusal plane remains unchanged, a twisting of the teeth / tooth elements of the dental arch (arc-shaped tooth element structure) or of the teeth / tooth elements of the two dental arches can be performed in the current occlusal plane, for example, about the surface normal of the occlusal plane. The twisting angle can be, for example, 1 to 5 degrees or 1 to 10 degrees.

[0120] In all these cases, relearning can be supported by optionally one or more sliding functions.

[0121] According to an embodiment, at least one device or at least one device pair can provide at least one additional dental technical function, i.e. in addition to the adjustment function of the plane, for example in addition to the sliding function. By the additional function itself, at least one device or at least one device pair is distinguished from at least one other device or at least one other device pair of the kit, i.e. the other device or the other device pair does not have this additional function.

[0122] The different functions may be one of the following: alignment function, shift function, height function, ramp function. These functions may be present only in one device or devices, for example, for adjusting the occlusal plane using a sliding contact surface, or in another device or pairs of devices. The function of adjusting a plane, in particular the occlusal plane, which can be achieved by at least one contact area at at least one height element may, for example, be present only in some devices of the kit and not in others.

[0123] The treatment time can be shortened by means of the one or more additional functions, since a plurality of functions can be carried out in parallel in time.

[0124] According to an embodiment, at least one device or at least one device pair can provide at least one additional function of another dental technology, i.e. in addition to the adjustment function of the occlusal plane on the contact area at the at least one height element and / or the sliding function in the sliding contact plane. At least one device or at least one device pair can have the additional function together with at least one other device of the kit or at least one other device pair of the kit in the same form of the functional element providing the function or in another form of the functional element providing the function.

[0125] Functions in the same form as functional elements providing a function may be: veneer element / dental veneer / form function (in particular with regard to the outer contour or the frontal contour or the canine contour) and / or color function.

[0126] By means of the one or more additional functions, it can be achieved, for example, that the person learns about the tooth target state or intermediate tooth target state relatively early. This can support adaptation or training. Furthermore, corrections can also be carried out early or the final medical object can be changed so that the person is satisfied with the final medical object, for example with regard to coloration and / or with regard to the tooth shape / tooth orientation or tooth element shape / tooth element orientation that is finally used.

[0127] The functions in different forms with functional elements providing a function may be: alignment function, shift function, height function, ramp function.

[0128] The treatment time can be shortened by means of the one or more additional functions, since, for example, a plurality of functions can be carried out in parallel in terms of time.

[0129] According to an embodiment, the arrangement may include an angle between a corresponding plane (e.g., a sliding plane) and a corresponding occlusal plane in a frontal plane. The angle between a corresponding plane (e.g., a sliding plane) and a corresponding occlusal plane in a frontal plane may change from one of the arrangements to an arrangement that follows the arrangement according to the sequence of the device. Alternatively or additionally, the arrangement may include an angle between a corresponding plane (e.g., a sliding plane) and a corresponding occlusal plane in a sagittal plane. The angle between a corresponding plane (e.g., a sliding plane) and a corresponding occlusal plane in a sagittal plane may change from one of the arrangements to an arrangement that follows the arrangement according to the sequence of the device.

[0130] Thus, all tilting movements of the occlusal plane can be carried out, ie in particular tilting movements in one spatial direction or in two spatial directions, for example orthogonal to one another.

[0131] According to an embodiment, the jaw device of the at least one device may include an upper jaw device and a lower jaw device, wherein:

[0132] - a flat first sliding surface area and a flat second sliding surface area can be present on the underside of the maxillary appliance,

[0133] - a flat third sliding surface area and a flat fourth sliding surface area may be present on the upper side of the mandibular device, and

[0134] In the use state of at least one device, the first sliding surface region and the fourth sliding surface region as well as the second sliding surface region and the third sliding surface region can slide relative to one another in a sliding plane.

[0135] At least one, at least two, at least three or all four sliding surface regions can be formed on the respective height element.

[0136] The use of four flat sliding surface areas allows for particularly precise orientation of the sliding plane, for example in the order of tenths of a millimeter, i.e. 100 micrometers and below. In addition, a sticky sliding effect or slip-stick effect can be used to promote relearning of the occlusal plane, i.e. a kind of pull-slide, which can significantly promote neuromuscular relearning, for example.

[0137] Furthermore, planar sliding surface areas are more robust than small sliding contact elements and are in particular more resistant to wear which could lead to an unnecessary shift of the occlusal plane.

[0138] Compared to a crack, the flat sliding surface area can be designed to be larger and can extend over a plurality of teeth or tooth elements, in particular over teeth or tooth elements which are adjacent to one another.

[0139] According to an embodiment, four sliding surface areas may have surfaces with lower mechanical friction resistance compared to other surfaces, for example to facilitate sliding.

[0140] According to an embodiment, in the first device or the jaw device of the first device pair (eg, the upper jaw device and / or the lower jaw device), the following features may be achieved:

[0141] - the deepest point of the right receiving area for the right tooth / tooth element has a right distance to a plane (eg a sliding plane),

[0142] - the deepest point of the left receiving area for the left tooth / tooth element has a left distance to a plane (eg a sliding plane),

[0143] The first frontal difference may be obtained by subtracting the value of the right distance from the value of the left distance.

[0144] In the second device or the jaw device of the second device pair (e.g. the upper jaw device and / or the lower jaw device), the following features can be achieved:

[0145] - the deepest point of the right receiving area for the right tooth / tooth element has a right distance to a plane (eg a sliding plane),

[0146] - the deepest point of the left receiving area for the left tooth / tooth element has a right distance to a plane (eg a sliding plane),

[0147] The second frontal difference may be obtained by subtracting the value of the right distance from the value of the left distance.

[0148] The value of the first frontal shape difference can differ from the value of the second frontal shape difference, in particular, for example, by at least 0.3 mm or at least 0.5 mm and / or by a value of 0.3 mm to 2 mm.

[0149] Embodiments may relate to two upper jaw devices of a first device or a first device pair and a second device or a second device pair, or to two lower jaw devices of a first device or a first device pair and a second device or a second device pair. In another embodiment, the above features may apply to both upper jaw devices of the two devices / device pairs and lower jaw devices of the two devices / device pairs.

[0150] When making comparisons, reference may be made to the absolute value (absolute value function), i.e., regardless of the sign. Alternatively, mathematical notation may be used.

[0151] The distance may be measured at the same tooth location in the maxillary appliance of the first appliance pair as in the maxillary appliance of the second appliance pair.

[0152] The distance may be measured normal to the plane or sliding plane, ie in particular the minimum distance. "Normal" may refer to the direction of the normal vector at the plane / sliding plane (ie for example perpendicular to the tangent vector).

[0153] Thus, the variation of the occlusal plane in the frontal plane can be significant, ie, different from random fluctuations, for example. This is especially true when the trend of the variation of the occlusal plane persists over a plurality of devices / device pairs.

[0154] According to an embodiment, in the first device or the jaw device of the first device pair (eg the upper jaw device and / or the lower jaw device), the following may be applicable:

[0155] the deepest point of the first right receiving area for the first right tooth / tooth element, for example as viewed from a person, has a first right distance to a plane, for example one of the sliding planes, in particular the first sliding plane or the fourth sliding plane,

[0156] the deepest point of the second right receiving area for the second right tooth / tooth element, for example viewed from a person, has a second right distance to the plane, for example the sliding plane,

[0157] Here, the first difference may be obtained by subtracting the value of the first right distance from the value of the second right distance.

[0158] In the second device or the jaw device of the second device pair (e.g. the upper jaw device and / or the lower jaw device), the following may apply:

[0159] - the deepest point of the first right receiving area for the first right tooth / tooth element, for example viewed from a person, has a first right distance to a plane, for example a sliding plane,

[0160] the deepest point of the second right receiving area for the second right tooth / tooth element, for example viewed from a person, has a second right distance to the plane, for example the sliding plane,

[0161] Here, the second difference may be obtained by subtracting the value of the first right distance from the value of the second right distance.

[0162] The value of the first difference can differ from the value of the second difference, in particular by, for example, at least 0.3 mm or at least 0.5 mm and / or by a value of 0.3 mm to 2 mm.

[0163] When making comparisons, reference may be made to the absolute value (absolute value function), i.e., regardless of the sign. Alternatively, mathematical notation may be used.

[0164] The first right tooth / tooth element and the second right tooth / tooth element may be adjacent to each other. In another embodiment, one or more teeth / tooth elements are present between the first right tooth / tooth element and the second right tooth / tooth element. This may apply to both teeth / tooth elements in the upper jaw and teeth / tooth elements in the lower jaw. Instead of teeth, other tooth elements or tooth element structures may also be present.

[0165] Thus, a change in the occlusal plane on the right side, for example in the sagittal plane, can be significant, ie, different from a random fluctuation, for example. This is especially true when the trend of the change in the occlusal plane persists over a plurality of devices / device pairs.

[0166] According to an embodiment, in the first device or the jaw device of the first device pair (eg the upper jaw device and / or the lower jaw device), the following may be applicable:

[0167] the deepest point of the first left receiving area for the first left tooth / tooth element, for example viewed from a person, has a first left distance to a plane, for example a sliding plane,

[0168] the deepest point of the second left receiving area for the second left tooth / tooth element, for example viewed from a person, has a second left distance to the plane, for example the sliding plane,

[0169] Here, the first difference may be obtained by subtracting the value of the first left distance from the value of the second left distance.

[0170] In the second device or the jaw device of the second device pair (e.g. the upper jaw device and / or the lower jaw device), the following may apply:

[0171] the deepest point of the first left receiving area for the first left tooth / tooth element, for example viewed from a person, has a first left distance to a plane, for example a sliding plane,

[0172] the deepest point of the second left receiving area for the second left tooth / tooth element, for example viewed from a person, has a second left distance to the plane, for example the sliding plane,

[0173] Here, the second difference may be obtained by subtracting the value of the first left distance from the value of the second left distance.

[0174] The value of the first difference can differ from the value of the second difference, in particular by, for example, at least 0.3 mm or at least 0.5 mm and / or by a value of 0.3 mm to 2 mm.

[0175] In the comparison, reference can again be made to the absolute value (absolute value function), ie, independent of the sign. Alternatively, the mathematical symbol can be used.

[0176] Thus, a change of the occlusal plane on the left side, for example in the sagittal plane, can be significant, ie, different from a random fluctuation, for example. This is especially true when the trend of the change of the occlusal plane persists over a plurality of devices / device pairs.

[0177] The first left tooth / tooth element and the second left tooth / tooth element may be adjacent to each other. In another embodiment, one or more teeth / tooth elements are present between the first left tooth / tooth element and the second left tooth / tooth element. This may apply both to teeth / tooth elements in the upper jaw and to teeth / tooth elements in the lower jaw. Instead of teeth, other tooth elements or tooth element structures may also be present.

[0178] Embodiments may involve a first device and a second device or two upper jaw devices of a first device pair and a second device pair, or involve a first device and a second device or two lower jaw devices of a first device pair and a second device pair.

[0179] In an embodiment, the above features may be applicable to both the upper jaw devices of the two devices / device pairs and the lower jaw devices of the two devices / device pairs.

[0180] Combinations with the above-described embodiments are also possible, namely changing the inclination in the frontal plane and changing the inclination in the sagittal section / lateral sagittal section. Thus, the occlusal plane can be shifted in all desired directions.

[0181] According to an embodiment, the jaw device of the first device (e.g., the upper jaw device of the first device or the first device pair or the lower jaw device of the first device or the first device pair) preferably has at least one (first) veneer element or at least one dental veneer on its front side. The jaw device of the second device (e.g., the upper jaw device of the second device or the second device pair or the lower jaw device of the second device or the second device pair) preferably has at least one (second) veneer element or at least one dental veneer on its front side.

[0182] According to an embodiment, at least one jaw device of the first device can have, on its outer side, a first covering element as a subregion of the first device, in particular as a subregion of the first jaw device.

[0183] According to an embodiment, at least one jaw device of the second device can have, on its outer side, a second covering element as a subregion of the second device, in particular as a subregion of the second jaw device.

[0184] According to an embodiment, at least one optional jaw device of the third device can have a third veneer element as a sub-region of the third device on its outer side. The inclusion of an optional third jaw device can be used in particular to divide a "rocking movement" at the tooth element.

[0185] All three veneer elements can be located at the same position according to the dental plan. The veneer elements can also be called dental veneers.

[0186] In the first cross section, a first outer contour and a first inner contour, in particular a front outer contour and a front inner contour, can be present at the first cladding element.

[0187] In a second cross section corresponding to the first cross section, a second outer contour and a second inner contour, in particular a front outer contour and a front inner contour, may be present at the second cladding element.

[0188] Preferably, the following feature can also be optionally realized: in a third cross section corresponding to the first cross section, at or in the third cladding element, a third outer contour and a third inner contour, in particular a front outer contour and a front inner contour, can be present.

[0189] The relative position of the respective inner contour and the respective outer contour can be changed progressively from the first veneer element to the second veneer element or from the first veneer element via the second veneer element to the third veneer element, in particular in order to achieve or cause a shift of the dental element in the associated receiving area, in particular in at least one or more of the following directions:

[0190] - From front to back

[0191] - From back to front

[0192] -Axial torsion

[0193] - laterally towards the adjacent teeth, i.e. to the left or right,

[0194] - Also where applicable, a shift from top to bottom or from bottom to top.

[0195] The change in relative position or offset can be strictly monotonous, in particular strictly monotonically increasing or decreasing in one direction. Alternatively, a simple monotonically increasing can also be achieved. Thus, in a series of devices following one another, there can also be devices whose relative position remains unchanged, for example because the offset is caused at other teeth.

[0196] Therefore, depending on the sequence, there may be no additional device between the first device, the second device and the third device. On the other hand, depending on the sequence, there may also be additional devices between the first device and the second device and / or between the second device and the third device.

[0197] The numbering of the devices may be different from the numbering in the treatment plan, but it does not have to be so. That is, the first device may be the first device according to the treatment plan. Alternatively, the first device may also be another device according to the treatment plan, such as the second device, the third device, etc. According to the claims, the other numbers follow.

[0198] According to the claim, the first device can have a relative position of inner and outer contour A. According to the claim, the second device can have a relative position of inner and outer contour B. According to the claim, the third device can have a relative position of inner and outer contour C. Then, the following sequence of positions can be achieved: A, B, C or A, A, B, C, C or similar.

[0199] The cross section may, for example, have a target occlusal plane as a reference, or have a plane at a predetermined distance from the target occlusal plane.

[0200] The relative position of the first inner contour to the first outer contour may be different from the relative position of the second inner contour to the second outer contour.

[0201] The migration of the inner contour relative to the dental arch can be greater than the migration of the outer contour relative to the dental arch. This means that the teeth can "move" relatively strongly, and the dental veneer (i.e. preferably its front side) can be stationary or only move relatively slowly.

[0202] The inner contour may comprise a pressing element, ie a functional element for tooth displacement, in particular a pressing element which causes displacement with at least one additional attachment at the tooth or tooth element or without an attachment at the tooth or tooth element.

[0203] The change in the relative position of the inner contour to the outer contour can be shown in the change in the wall thickness profile. Thus, the wall thickness profile of the first facing element (in particular the front wall thickness profile) can differ from the wall thickness profile of the second facing element, and the wall thickness profile of the third facing element (in particular the front wall thickness profile) can differ from the wall thickness profile of the second facing element and also from the wall thickness profile of the first facing element, in particular due to a targeted change in the relative position of the respective inner contour to the respective outer contour, for example in contrast to a deep-drawing process using a film of uniform layer thickness, in which the inner contour and the outer contour coincide with each other and thus have a substantially constant position relative to each other.

[0204] The technical effect of the variation of the relative position of the inner and outer contours is that a degree of freedom is created to achieve the position of the outer contour independently of the position of the inner contour. For example, the outer contour can be achieved or desired at an early stage in the kit, while the inner contour "models" the dental element or achieves the migration of the dental element.

[0205] The receiving area of ​​the first veneer element may be designed differently from the receiving area of ​​the second veneer element and / or have a different position than the receiving area of ​​the second veneer element. This difference may be suitable for causing a gradual migration of the dental element. At the same time, the front wall thickness of the second veneer element may be different from the front wall thickness of the first veneer element, especially when the dental element migrates from front to back or from back to front.

[0206] Thus, when the dental element migrates from back to front, the wall thickness, in particular the front wall thickness, can generally decrease from the first veneer element to the second veneer element and, where applicable, also from the second veneer element to the third veneer element. Here, the rear wall thickness can, for example, increase accordingly or remain unchanged.

[0207] Thus, when the dental element moves from front to back, the wall thickness, in particular the front wall thickness, can generally increase (along the entire course of the wall in the cross section) from the first veneer element to the second veneer element and, where applicable, also from the second veneer element to the third veneer element. In this case, the rear wall thickness can, for example, decrease accordingly or remain unchanged.

[0208] When a tooth element undergoes a lateral migration, the anterior wall thickness may decrease in a sub-region and increase in another sub-region. However, the wall thickness to the adjacent tooth element may decrease or increase overall or in the entire course of the wall, in particular when the adjacent tooth elements are not migrated simultaneously. The same applies to a rotation of the tooth or a lifting of the tooth from the upper or lower jaw or a combined migration, such as a rotation and a lifting.

[0209] The first veneer element can be located at the same position as the second veneer element according to the dental plan. According to an embodiment, the receiving area configured in the first veneer element can be designed differently from the receiving area configured in the second veneer element and / or have a different position than the receiving area configured in the second veneer element. Known dental plans are quadrant plans with four quadrants, such as (as viewed from the patient) upper right, upper left, lower left and lower right, or tooth numbering from left to right or from right to left in the upper or lower jaw.

[0210] Such design and / or positional differences may be adapted to cause a gradual migration of the dental element.The front wall thickness of the second veneer element may differ from the front wall thickness of the first veneer element, eg due to such design and / or positional differences.

[0211] This kit makes it possible to implement or approximate the position and / or shape of teeth or tooth elements, for example after the final treatment, at an early stage in the device. If the position or shape still changes during the treatment, for example, reference can be made to a temporary target state of the teeth / tooth elements. Other dental technical features are also conceivable.

[0212] The frontal plane outer contours of the at least one first cladding element and the at least one second cladding element may be substantially identical in position and / or shape.

[0213] At least one dental veneer of the first device / first device pair may be located at the same tooth position as a dental veneer / veneer element of the second device / second device pair. At least one dental veneer / veneer element of the first device / device pair and at least one dental veneer of the second device / device pair may be adapted to the tooth located at the tooth position in a target tooth state or an intermediate target tooth state, or conform to it, or present an enlargement (e.g. 1% to 10% enlargement) of the target tooth state or the intermediate target tooth state. The enlargement may be isotropic, i.e. uniformly enlarges in all directions, or anisotropic.

[0214] The intermediate target or intermediate target tooth state can be derived from the intermediate target of the treatment. For example, from the perspective of the devices considered in sequence, the intermediate target tooth state is first reached for at least one device and then for multiple devices.

[0215] The at least one first veneer element (dental veneer) and the at least one second veneer element (dental veneer) may be substantially identical in position and / or shape of the front outer contours thereof.

[0216] For example, in the case of a relatively small dental element of interest (such as a tooth, a tooth root or an implant, etc.), the front outer contour can be adapted to the dental element at this tooth position in a target dental state, as desired in the final medical body of the dental element. Alternatively, the front outer contour can also be adapted to an intermediate target dental state (e.g. an intermediate target tooth arrangement).

[0217] The tooth elements can be considered as residual occlusal elements. A plurality of residual occlusal elements can form a residual occlusal structure. Together with the device, the residual occlusal structure and the device can produce a temporary occlusal structure, which is then transformed into a permanent occlusal structure in the final dental workpiece, which corresponds exactly to the target occlusal structure or has only relatively minor deviations due to the tooth condition.

[0218] The relocation of one or more dental elements may be part of a treatment plan. Only a portion of a dental element may be relocated. Another portion may already be in a suitable position, so that no relocation is required with respect to this portion.

[0219] "Fit" may mean to be consistent. Alternatively, "fit" may mean to be consistent with the target state as long as dental conditions allow.

[0220] The enlargement can be effected in at least one spatial dimension or spatial direction, for example anisotropically in at least two spatial dimensions (orthogonal directions), for example anisotropically or in all three spatial dimensions / directions (isotropically).

[0221] Isotropic enlargement can be, for example, so-called expansion in undersized canines or premolars. On the other hand, anisotropic enlargement can be, for example, an increase in width without proportional enlargement of the other dimensions or without enlargement at all. Preferred directions of enlargement can be labial, labial-lingual, buccal and buccal-lingual.

[0222] Furthermore, the target tooth state may be broader than the associated single tooth and the associated entire dental arch. The dental arch in the device may be an anticipation of the target state of the dental arch in the maxilla and / or mandible, in particular an anticipation of the outer contour and / or the inner contour. It is often desirable to enlarge the dental arch in the maxilla or mandible or to enlarge both dental arches. The dental arch may comprise teeth or tooth units, i.e. the dental arch may be an arc-shaped tooth element structure.

[0223] The front outer contour can present an enlargement of the target tooth state in at least one dimension. According to another improvement, the front tooth veneer of the first device pair and the front tooth veneer of the second device pair can present the teeth located at the tooth position in the target tooth state or under the enlargement of the target tooth state. The enlargement can be achieved by a value of, for example, 1% to 25%, preferably 5% to 15%, for example 10%. The enlargement can be achieved using a factor (for example, an enlargement factor of 1.01 to 1.25). The target tooth state or its enlargement can include the shape, color, position, orientation, etc. of the relevant teeth (for example, relevant front teeth, canines, etc.). The tooth veneer and / or enlargement can increase and / or ensure the stability of the device and is therefore a technical feature.

[0224] Therefore, in the design scheme, the veneer can be a model or anticipation of a target tooth state or an intermediate target tooth state. On the other hand, as mentioned above, the veneer can also be designed according to other criteria.

[0225] The veneer / veneer element can be placed in the mouth of a person to veneer the corresponding tooth. For example, the veneer can include a recess for the relevant tooth, in particular a recess with an alignment function or without an alignment function (i.e., depending on the treatment plan for the person). Alternatively, the veneer can also only partially surround the relevant tooth, for example, only be arranged on the front side of the tooth, but not on the back side of the tooth.

[0226] It is also possible to use dental veneers / veneer elements which are not assigned teeth, for example due to corresponding tooth loss. In this case, the dental veneer can assume a supporting function on the soft tissue or on or at the implant. These functions are described in detail below.

[0227] At least one dental veneer / veneer element can reproduce the physical outer contour or slightly enlarged outer contour or outer geometry of the teeth in the target state. Thus, a corresponding sensory impression can be produced in the mouth of the wearer of the device (i.e. the person), for example on the inside of the lip or the inside of the cheek. Therefore, only one adaptation to the target tooth arrangement is required, which increases the person's acceptance of multiple devices. If the person still finds the target tooth arrangement uncomfortable or unsuitable after the adaptation, a correction of the target tooth arrangement can be performed at an early stage, i.e. at the beginning or in the first third of the treatment. User acceptance increases, because the user can see or feel the result at the end of a long treatment at the beginning of the treatment.

[0228] The doctor and / or orthodontist and / or person can recognize at any time based on the position of the recess in the device how far the actual state of the teeth is from the target tooth state, because, for example, the distance of the recess to the frontal target surface is shortened. The same applies to intermediate target tooth positions or intermediate target tooth arrangements. The dentist or orthodontist can observe how close the actual state is to the target tooth position, especially at the front of the dental veneer, by comparing the actual state of the teeth with the target tooth state shown by the dental veneer.

[0229] The veneer can be designed on its outer surface like the outer surface of the target arrangement or designed slightly differently, for example due to enlargements to be taken into account and / or within the scope of manufacturing tolerances and / or within the scope of deviations of less than 1 mm or less than 0.5 mm. Very thin veneers can be used when the relevant teeth have reached their final position and are not to be modified by structures or attachments in the final treatment. It is also possible to use a break in the veneer so that the tooth surface that has reached the final position is no longer veneered, but the tooth surface is arranged so that it is freely visible from the front.

[0230] The device may comprise a device pair. Alternatively, a plurality of devices separated from each other, such as a left device and a right device, may be used for the mandible or the maxilla. In this case, the dental veneer may be arranged, for example, in the canine region.

[0231] In particular, the following dental veneers / veneers or anterior tooth replicas may be present:

[0232] - For example, from a human perspective, such as a first upper left front tooth veneer or a front tooth replica (not rooted in the jaw), and / or

[0233] - for example from a person, such as a first lower left anterior veneer or anterior replica (not rooted in the jaw), and / or

[0234] - For example, from a human perspective, such as a second upper right anterior veneer or anterior replica (not rooted in the jaw), and / or

[0235] - For example, from a human perspective, such as a second upper left front tooth veneer or a front tooth replica (not rooted in the jaw).

[0236] In all devices of the kit or in at least half of the devices or device pairs of the kit, the front side of at least one dental veneer / veneer element can have the same position relative to the person's skull / facial features (in particular facial features determined by the skull features, i.e., features in particular for determining the target alignment).

[0237] According to an improved solution, when replacing a device pair in a person's mouth, the second device or at least one dental veneer / veneer element of the second device pair can be located at the same position in the mouth as the first device or at least one dental veneer / veneer element of the first device pair.

[0238] The third device / device pair of the kit can be located after the second device / device pair in the sequence. The third device / device pair can also include at least one dental veneer / veneer element that is constructed similarly to the at least one dental veneer / veneer element at the first device / device pair and / or similarly to the at least one dental veneer / veneer element at the second device / device pair.

[0239] The sequence of the devices can be predetermined by a treatment plan, in particular a digital treatment plan stored in a computer. At the end of the treatment, it is also possible, for example, to use only one device instead of a device pair.

[0240] The dental veneer / veneer element can cover the teeth or the dental elements located behind them and / or can preferably have the color and / or shape of the teeth, that is, the dental veneer / veneer element can be made of opaque material or include an opaque material layer, for example made of yellow or white material.

[0241] The dental veneer / veneer element can be made of a different material than the deep-drawn film, i.e. a material with regions of different layer thicknesses, for example with a thickness difference of more than 1 mm or more than 2 mm. The device or dental veneer / veneer element made from the deep-drawn film has essentially the same layer thickness. An alternative production method to deep-drawing can be the use of subtractive methods (e.g. milling) or additive methods.

[0242] According to an embodiment, the first device or the first device pair and / or the second device or the second device pair or at least one further device or at least one further device pair of the kit may include a functional element that applies one or more alignment functions to teeth / tooth elements or applies one or more alignment functions to teeth / tooth elements, and / or applies a displacement function to teeth / tooth elements or applies a displacement function to teeth / tooth elements in relation to at least one dental arch (arc-shaped dental element structure) of a person in order to bring at least one dental arch of a person into a new condition, for example in order to expand the dental arch.

[0243] The new condition may in particular be an expansion of the dental arch (arc-shaped tooth element structure) in the upper and / or lower jaw, for example in order to create space for a dental reconstruction or a dental implant.

[0244] In particular in combination with the above-mentioned dental veneer / veneer element, at least one dental veneer or veneer element can result in: at the person's teeth, in the area that was previously covered, applying an alignment function of the teeth and a displacement function with respect to at least one dental arch of the person so as to bring at least one dental arch of the person into a new condition, while the previously visible position of at least one dental veneer / veneer element remains the same or changes only slightly, preferably remains the same or changes only slightly over the course of the entire kit or in a sub-area of ​​the kit that includes at least 20% of the devices of the kit.

[0245] According to an embodiment, at least a part of the device or device pair can be configured such that in the molar region of a person, a height structure is first achieved by a height function (e.g. using a height element). The height structure can be suitable for increasing the distance between the mandible and the maxilla in contact occlusion and leading to unlocking of previously blocked tooth migration. Additionally or alternatively, the occlusal plane can be migrated or changed by the height function. At least another part of the device / device pair is configured such that, after unlocking is achieved by the height function, tooth migration of the person's teeth is achieved by an aligner-function as part of a subsequent device / device pair and / or a change of the person's dental arch is achieved by a shifting function as an additional part of a subsequent device / device pair.

[0246] The first device or first device pair and / or the second device or second device pair can belong to devices or device pairs that implement a height structure by means of a height function, which, for example, expands or corresponds to a function for adjusting the occlusal plane and / or can supplement a sliding function. Thus, according to an embodiment, a height structure is first implemented, wherein an adaptation and / or training of a preferred neuromuscular relearning of the occlusal plane can be implemented. After this, a device with an alignment function can be used in the previously blocked area. In an embodiment, a blockage in at least one area can be resolved, wherein the execution of an alignment function and / or a displacement function has already begun in at least another area, in particular an unblocked area.

[0247] According to an embodiment, preferably when constructing the sliding area or sliding surface area, the roughness depth Rz (roughness value, roughness) on at least one contact area can be less than 5 microns, or the average roughness Ra on at least one contact area / sliding area can be less than 1.5 microns or less than 1.3 microns.

[0248] The so-called mean roughness depth (also called ten-point height), previously denoted by the symbol Rz (according to DIN (German Industrial Standard) EN (European Standard) ISO (International Organization for Standardization) 4287:1984), is no longer valid as an ISO characteristic value (from DIN EN ISO 4287:1997).

[0249] However, the mean roughness depth Rz can still be output by older measuring equipment and can be determined as follows:

[0250] The measurement section defined on the surface of the workpiece is divided into seven individual measurement sections, of which the five central measurement sections are of equal size. The evaluation is performed only on these five measurement sections, since the Gaussian filter to be applied requires the first and second individual measurement sections, or the convolution has a non-negligible start and end behavior.

[0251] The difference between the maximum and minimum values ​​is determined for each individual measured section of the profile.

[0252] - Calculate the average value from the five individual roughness depths obtained.

[0253] The average roughness Ra can be formed according to DIN EN ISO 4287:2010 as follows:

[0254]

[0255] The mean value z can be calculated as follows:

[0256]

[0257] The mean roughness depth Rz can be converted into a mean roughness value, for example 5 micrometers Rz can correspond to a mean roughness Ra of 1.3 micrometers to 0.25 micrometers, where the average estimated value can be 0.812 micrometers, see for example https: / / www.facturee.de / online-tools / rz-ra-rechner / . This corresponds to a roughness level N of 7, which can be achieved, for example, by fine machining. Therefore, surfaces with a roughness level lower than 8 or 7 can be used.

[0258] According to an embodiment, at least a part of the devices or device pairs or all devices or device pairs can consist uniformly of a single material. This can enable simple production, which is particularly cost-effective.

[0259] According to an embodiment, in particular according to an alternative embodiment, at least a part of the device or device pair or all devices or device pairs can include at least two materials that are different from each other, preferably a first material in the outer area and a second material in the inner area surrounded by the outer area. Compared to the second material, the first material can have a greater hardness. Alternatively, compared to the first material, the second material has a greater hardness.

[0260] When a harder material is used as the material in the outer region (first material), wear can be reduced and the wearing comfort can be increased by the softer material in the inner region.

[0261] As materials, in particular health-friendly plastics can be used, for example synthetic resins such as acrylic resins, epoxy resins or vinyl ester resins, polyurethane PU, PMMA (polymethyl methacrylate), multilayer PMMA or the like.

[0262] According to another embodiment, the device or device pair or these devices or device pairs that cause a change in the position of the occlusal plane (in particular the inclination of the occlusal plane) and / or realize a preferred neuromuscular relearning of the occlusal plane can be designed so that a lateral movement and / or an anteroposterior movement of the modules relative to each other and to the teeth or other tooth element structures is possible. The additional degree of freedom in the relative movement can accelerate the relearning. Therefore, a combined movement consisting of a lateral movement and an anteroposterior movement (i.e., for example a diagonal movement or a rotational movement) can also be beneficial. Other directions of relative movement are, for example: anteroposterior, left-right or a combination of anteroposterior and left-right.

[0263] The receiving area can be dimensioned to form a transverse edge gap, preferably a transverse edge gap around at least one tooth or around at least one tooth element. Preferably, an occlusal edge gap can also be formed, which is only interrupted by a smaller support surface (e.g. a point-shaped support surface) than the occlusal edge gap, which can be adapted to the tooth contour. The transverse edge gap or the occlusal edge gap can have a width of, for example, 0.3 mm to 1.4 mm or 0.4 mm to 1.4 mm. The transverse edge gap or the occlusal edge gap can be greater than 0.3 mm. The upper limit of the transverse edge gap or the occlusal edge gap can be less than 3 mm, less than 2 mm or less than 1.75 mm.

[0264] The biomechanical and neurophysiological effects or improved effects of the device pair which can be used as a training device can also occur in the case of a limited range of lateral movement of the teeth or tooth elements in the case of an optional marginal gap, because the training effect can be based on the mobility in the equilibrium position, which is given by the marginal gap. However, even without marginal gaps, good to very good training results can still be achieved. The training can be carried out consciously or unconsciously, for example during biting, in particular during eating.

[0265] If you don't use edge clearance, it's easier to apply the alignment function at the same time.

[0266] The training or adaptation to the new bite plane can be performed without additional exercises. In another embodiment, the training can include active conscious participation of the person, for example in the form of conscious bite and release exercises, for example to train the bite muscles. Release can be performed as soon as sliding starts, for example as soon as the maxillary device or mandibular device moves relative to the teeth in the marginal gap. Alternatively, as mentioned above, the training can also be performed without marginal gap. In this case, sliding occurs due to the sliding function. The training can also be performed without a sliding plane and sliding movements.

[0267] The two modules / devices of the device pair can be designed so that, in particular in the state of use, but also outside the oral cavity where applicable, when the modules / devices are placed accordingly on each other, the modules / devices are adjacent to each other in the region of the separation-sliding plane. The modules / devices of the device pair can in particular be adjacent to each other so that a lateral movement of the modules relative to each other and / or relative to the teeth is possible or permitted.

[0268] Thus, a lateral movement of the module / device relative to the tooth / one or more tooth element structures is possible, in particular if the tooth or tooth crack does not hinder such lateral movement. However, sliding and, where applicable, marginal clearance are optional, since even without sliding and / or marginal clearance, an adjustment or migration of the occlusal plane, in particular a tilting of the occlusal plane, can be performed.

[0269] Another aspect of the invention relates to a method for designing a dental device, in particular for designing or designing and manufacturing a kit according to one of the above embodiments, the method comprising:

[0270] - recording the initial tooth arrangement of the person's teeth or tooth elements or tooth element structures in their upper jaw and / or the initial tooth arrangement of the person's teeth or tooth element structures in their lower jaw,

[0271] - determining at least one reference structure of the person before, during or after the recording,

[0272] - determining a target tooth arrangement of teeth / tooth elements or tooth element structures of an upper jaw of a person relative to the upper jaw or a target upper jaw taking into account said reference structure, and / or

[0273] - determining a target tooth arrangement of teeth / tooth elements or tooth element structures of a human jaw relative to the jaw or a target jaw taking into account the reference structure,

[0274] - providing digital data that follow one another in sequence, for example with a data set of teeth / tooth elements or tooth element structures for the upper jaw and / or a data set of teeth / tooth elements or tooth element structures for the lower jaw, based on a starting tooth arrangement and at least one target tooth arrangement or intermediate tooth arrangement,

[0275] - designing a kit with devices (in particular for supporting a migration of a person's occlusal plane) based on the digital data, the kit comprising at least two devices, at least five devices, at least ten devices, etc.

[0276] The device may respectively comprise at least one jaw device. The at least one jaw device may comprise an upper jaw device and / or a lower jaw device. The device may be designed such that the device is worn by a person according to a predetermined sequence.

[0277] In at least one device, at least one jaw device may include at least one height element on a first side. At least two contact areas may be configured at the at least one height element at mutually different positions of the molar element. At least one further contact area may be configured on a second side of the at least one jaw device.

[0278] In an embodiment, at least three contact areas may define a plane. The plane may differ from the person's starting occlusal plane or the person's current occlusal plane with respect to its inclination in the frontal section or the sagittal section changed by at least one height element and / or with respect to its height position changed by at least one height element,

[0279] In an embodiment, in at least another device of the kit, another inclination and / or another height position of the corresponding plane in the frontal section and / or sagittal section is adjusted by at least one additional height element, which differs in the adjusted height from at least one height element.

[0280] In an embodiment, at least one device or device pair can provide at least one additional function of another dental technology, which is also provided by at least another device pair of the kit in the same or different manner. Here, reference is also made to the technical effects described in detail above.

[0281] In a design solution, the method may further include at least one of the following steps:

[0282] - Determining the force vectors required for tooth displacement, for example using the finite element method (FEM) or the finite difference method (FDM) or other suitable computer-based method.

[0283] - Based on the force vectors, the shape of the recess and / or the force transmission element (appendage and / or projection and / or active surface in the recess) in the device of the kit comprising at least two device pairs is determined.

[0284] The device associated with the method can also be constructed like the above-mentioned device, that is, for example, including an upper jaw device and a lower jaw device respectively. In the case of considering the force vector, the device pairs of the device can be designed so that they cause a gradual change in the position of the teeth of the person in the order of the device pairs.

[0285] There may be at least 10 devices, at least 20 devices or at least 30 devices in the kit. There may be fewer than 100 devices in the kit. The exact number of devices may be given in the treatment plan (particularly in a digital treatment plan) and may depend, for example, on whether attachments are used or the pressure on their teeth that the person concerned can still accept.

[0286] Digital data may include data sets or may be stored and / or structured in other suitable ways. Thus, for example, a database, in particular a relational database, may be used. Alternatively, data structuring may be achieved in other suitable ways and methods.

[0287] According to an embodiment, in at least two devices or device pairs, the maxillary device and / or the mandibular device each comprises at least one contact area at the height element, for example at least one sliding contact area. In a first device or a first device pair of at least two devices / device pairs, a first receiving area for a tooth or tooth element structure of the maxilla or mandible can be arranged according to a first arrangement relative to a first plane / sliding plane of the first device or the first device pair. In a second device or a second device pair of at least two devices / device pairs, a second receiving area for a tooth or tooth element structure of the maxilla or mandible can be arranged according to a second arrangement different from the first arrangement relative to a second plane / sliding plane of the second device or the second device pair.

[0288] By means of a second arrangement different from the first arrangement, it is possible to relearn the position of a person's occlusal plane from a plane / occlusal plane associated with the first arrangement to a plane / occlusal plane associated with the second arrangement, in particular to relearn the inclination of a person's occlusal plane from a plane / occlusal plane associated with the first arrangement to a plane / occlusal plane associated with the second arrangement, preferably to achieve neuromuscular relearning.

[0289] Alternatively or additionally, the height position of the plane / occlusal plane can also be varied, for example the distance of the plane / occlusal plane from the upper jaw, for example this distance can be reduced or increased.

[0290] In addition or alternatively, where applicable, a lateral shift of the plane / occlusal plane may also be performed or realized in the current plane / occlusal plane, for example from back to front, from front to back, rotationally, from left to right or from right to left, etc.

[0291] The receiving area can have side walls which can be arranged transversely to the tooth or tooth element. Functional elements which press laterally on the tooth / tooth element or exert a force on the tooth / tooth element in another way can be arranged at the side walls.

[0292] The data can be provided using any suitable method, for example:

[0293] - Collision detection using an OBB (Oriented Bounding Box) tree / graph, and / or

[0294] -Use Voronoi diagram to represent three-dimensional structures.

[0295] Recording the starting tooth arrangement of the teeth / tooth element structure may also include recording a skeletal image of the patient's head or skull, wherein the image also shows the position of the lower jaw in the lower jaw starting position, the position of the upper jaw in the upper jaw starting position, and the position of the teeth / tooth element structure of the upper jaw in the starting tooth position and the position of the teeth / tooth element structure of the lower jaw in the starting tooth position.

[0296] Determining the reference structure may include determining at least one reference plane taking into account at least one structure / structural feature of a skull of a skeletal image of a person's (patient's) head or facial structural features of a person's face, wherein the facial features are preferably closely related to the skull structure.

[0297] Consideration of skull features may be a prerequisite for long-term treatment success. Skull structures may be structures other than the upper jaw of a person and / or structures other than the lower jaw of a person. Skull structures may:

[0298] -Features involving the skull and / or head, such as the temples, ears, inner ear region, eye sockets, cheekbones, etc.

[0299] - Suitable for determining a sagittal plane, such as the mid-sagittal plane through the skull, particularly half way between features that appear in pairs (ie exactly between the determined inner ear regions or between other features mentioned above, etc.).

[0300] - Suitable for determining essentially transverse planes, such as a target occlusal plane, see EP 3 332 731 A1 ("CranioPlan" (may be a trademark)), which is incorporated herein by reference for all legal purposes.

[0301] The reference structure may, for example, comprise a Cartesian reference plane system as proposed in WO 2020 / 141134 (3D structure marking or 3D ruler) for determining the separation-slip plane of a training device, but may also be used for other purposes, such as for the proposed method. WO 2020 / 141134 A1 is incorporated herein by reference for all legal purposes.

[0302] If, for example, the sagittal plane or an axis transverse thereto is known, planes orthogonal thereto, for example at least one frontal plane or a group of frontal planes and / or at least one transverse plane or a group of transverse planes, can be determined.

[0303] Depending on the implementation (CranioPlan - which may be protected as a trademark or otherwise), determining the reference structure may include:

[0304] i) determining the inner ear axis, preferably using digital 3D image data,

[0305] ii) determining the position of at least one eye,

[0306] iii) determining at least one skull plane including the axis of the inner ear and the position of at least one eye,

[0307] iv) Using the skull plane as an auxiliary plane or to calculate an auxiliary plane, for example by determining the average of two planes each including the eye position.

[0308] v) Use auxiliary planes to determine the occlusal plane by:

[0309] A1) determining a torsion axis which is parallel to the inner ear axis and is located on the other side of the inner ear axis compared to the eye axis,

[0310] A2) using the twist axis to twist the auxiliary plane downward by a predetermined angle, such as an angle of 11 to 17 degrees or an angle of 13 to 15 degrees, so as to obtain a target occlusal plane or a plane parallel to the target occlusal plane, or

[0311] B1) Twist the auxiliary plane around the inner ear axis to obtain a second auxiliary plane,

[0312] B2) Shift (translate) the second auxiliary plane downwards.

[0313] Step B2) may be performed in order to obtain a target occlusal plane or a plane parallel to the target occlusal plane,

[0314] In step B2), the auxiliary plane can be displaced, for example, by a section over which the displaced second auxiliary plane coincides with the target occlusal plane obtained according to alternative A.

[0315] The exact angle can be determined with the aid of a sphere that is digitally fitted to digital data describing the foramen magnum, the large oval opening in the occipital bone of the skull (ie, the back of the head).

[0316] The position of the torsion axis can be determined, for example, by the following method:

[0317] - determining a first center point of the inner ear axis between two inner ear points,

[0318] - determining a second center point of the eye axis between the two eye points,

[0319] - determining the distance between the first center point and the second center point,

[0320] - determining a connecting straight line between the first center point and the second center point,

[0321] - Extend the connecting straight line backwards by a length that is approximately twice the determined distance (e.g. 1.5 to 2.5 times or 1.75 to 2.25 times or 1.9 to 2.1 times) to obtain the point through which the torsion axis passes, i.e. the original length of the section between the two center points, e.g. tripled.

[0322] In contrast to the plane, the method, hereinafter referred to as "CranioPlan" (may be a trademark), can also determine and / or take into account the so-called Speer curve of the tooth occlusal plane. In this case, for example, the position of the tooth in the center of the right jaw (maxilla or mandible) or in the center of the right jaw (maxilla or mandible) can be offset, wherein the corresponding tooth can be arranged below the occlusal plane.

[0323] The "CranioPlan" (which may be a trademark) method or the method according to Hornung is described in detail in EP 3 332 731 A1. This document is incorporated herein by reference for all legal purposes.

[0324] According to another method, facial features, in particular facial features corresponding to the above-mentioned bony features of the facial skull, can be used. Thus, the radiation exposure caused by X-rays can be reduced or completely avoided.

[0325] The method known as "CranioPlan" (which may be a trademark) may be performed manually, semi-automatically or automatically, in particular computer-assisted.

[0326] According to another embodiment (3D structure marker / 3D marker / 3D ruler), in particular an alternative embodiment, determining the reference structure may include:

[0327] -3D imaging and generation of digital data,

[0328] - manually identify or automatically identify anatomical landmarks using digital data,

[0329] - defining the transverse direction using the identified anatomical landmarks, thereby also determining the direction of the sagittal plane Sm,

[0330] - determine the center points between anatomical landmarks,

[0331] - Use a digital 3D structure marker consisting of at least three flat packages:

[0332] -1) a transverse plane bag comprising a plurality of transverse planes parallel to each other,

[0333] -2) a frontal plane package, which includes a plurality of frontal planes parallel to each other, and

[0334] -3) at least one sagittal plane package comprising a plurality of sagittal planes parallel to each other,

[0335] - introduce 3D structural markers into the 3D image space involved in the digital data,

[0336] - When the midsagittal plane Sm is determined, the 3D structural marker is oriented to the determined center point. Alternatively, the sagittal plane is first placed at the determined center point and then in a separate step the center plane of at least one sagittal plane package is oriented, for example coincidentally, to the previously placed sagittal plane.

[0337] - translating the 3D structure marker to a first anchor point, which is preferably located in the midsagittal plane Sm,

[0338] - twisting the 3D structure marker using a second anchor point, e.g. rotating to the second anchor point,

[0339] - scaling the 3D structure marker using the third anchor point, in particular isotropically scaling the 3D structure marker,

[0340] - Use 3D structural landmarks to determine the ideal occlusal plane.

[0341] A preferred method is described below, where the lateral direction is first determined based on anatomical landmarks (part A) and then a further adaptation step is performed (part B). Here, the user can create an axis in the image plane at the anatomical landmark (e.g. the zygomatic bone, eye socket or inner ear region) or a plane perpendicular to the image plane, since this plane is displayed as a line in the cross-sectional view.

[0342] Part A

[0343] -1)-3D imaging: In the first step, a 3D image of a body part (e.g., a patient's head) can be achieved.

[0344] -2) Generate digital data: Through the processing of the images, a digital or virtual 3D body can be generated in the second step. Steps 1 and 2 can also be performed in one step.

[0345] -3) Visualization: In the third step, a cross-section of this 3D body can be displayed.

[0346] -4) Identification of anatomical landmarks: In the fourth step, the landmarks of the bone structures can be identified in the appropriately selected cross-sectional views.

[0347] -5) Defining transverse directions: In a fifth step, at least one transverse direction can be defined, which for example connects two symmetrical marks. This can be achieved by an axis, or by a plane and a second plane intersecting it.

[0348] -6) Defining the direction of the sagittal plane: In the sixth step, the definition of the position of the mid-sagittal plane Sm can be achieved, whose orthogonal normal is the transverse axis or is parallel to the transverse axis.

[0349] -7) Determine the center point: In the seventh step, the center can be determined between suitable markers so that the midsagittal plane Sm of the upper facial skull can be accurately determined. This may not be completely clear or provide a certain degree of freedom, because the skull in the posterior region usually has a different orientation than the anterior upper facial skull, up to 2 degrees. A practical solution based on an average method or previous experience is provided here.

[0350] -8) Determining the position of the median (middle) sagittal plane Sm: In the eighth step, the median sagittal plane Sm can be determined by the center point determined in the seventh method step and the orthogonality caused by the determined cross-sectional directions.

[0351] -9) Check other views: In the optional ninth step or in multiple such steps, other cross-sectional views can be obtained to control position and orientation or to complete other tasks and problems.

[0352] In part A, the order of the steps can be varied as long as the result is the orientation of the sagittal plane defined by means of anatomical landmarks.

[0353] For part B, the following 3D structural mark (abbreviated as mark (label) or ruler (ruler)) can be used, which structural mark can include at least three flat packages.

[0354] -1) a flat bag comprising a plurality of mutually parallel transverse planes,

[0355] -2) a flat bag, which comprises a plurality of frontal planes parallel to each other, and

[0356] -3) at least one plane package, which includes a plurality of sagittal planes parallel to each other, such as a left sagittal plane package and a right sagittal plane package.

[0357] The known Fibonacci sequence or Fibonacci arrangement is: 3, 5, 8, 13, 21, etc., i.e. the next number in the sequence is the sum of the first two numbers. This sequence can be used to determine the distances of the planes in a three-plane package, for example, the first two planes are at a distance of, for example, 3 mm from each other, the second and third planes are at a distance of, for example, 5 mm from each other, the third and fourth planes are at a distance of, for example, 8 mm from each other, etc. Alternatively, the plane distances (e.g. the same distance between adjacent planes) can also be selected by other means or methods. Then, by the above-mentioned scaling, the distances can be scaled (e.g. enlarged).

[0358] 3D structural markers can also be used to directly determine the mid-sagittal plane or a plane parallel thereto.

[0359] Part B

[0360] -1) Add 3D markers: In the first step, the 3D structure marker can be introduced and inserted into the 3D image space so that it can be seen in the view. At this point, the flat package can be displayed as parallel lines.

[0361] -2) Orienting the 3D marker to the mid-sagittal plane Sm: In a second step, the structure marker can be oriented with its intra-sagittal plane structure perpendicular to the transverse axis of the bone structure.

[0362] -3) Translation of 3D markers: In a separate third step, a 3D structure marker may be placed on an anchor point in the midsagittal plane, in an embodiment, such as the intersection of lines or planes T3 (third transverse plane) and F5 (fifth frontal plane) in the midsagittal plane Sm at the base point BP of the foramen magnum.

[0363] -3) Twisting the 3D marker: In a fourth step, the 3D structure marker may be oriented by rotating (twisting) around an axis parallel to the transverse axis so that in the sagittal plane image, the transverse plane stretches in the direction of a connecting line, such as along the axis BP-GP (palatal point). In an embodiment, the rotation may be performed around a fixed point where the intersection points T3 and F5 are located. The rotation brings the line T3 into a position passing through two anchor points, such as the base point BP and the palatal point (GP). Thus, the 3D structure marker is oriented at an angle.

[0364] -5) Scaling the 3D markers: In the fifth step, the frontal line can be made to pass through a suitably selected third anchor point by linear scaling of the markers or linear scaling of the 3D structure markers. In an embodiment, the third anchor point can be the nose point NP (Nasionspunkt). In an embodiment, the correct individual scaling size is achieved when the frontal line F1 and thus the frontal plane passes through the nose point or the Nasionspunkt NP.

[0365] -6) Analysis of symmetry: In a subsequent optional sixth step, the proportions of the body parts can optionally be analyzed for symmetry and harmony. Thus, inclinations or inclination shifts, for example of the mandible and the current occlusal plane, are often indicated.

[0366] -7) Determination of the ideal occlusal plane: In a further seventh step, for example, a first transverse plane (e.g. referred to as T1) can be used as an idealized occlusal surface or an idealized occlusal plane for the subsequent orientation of, for example, a prosthesis or an appliance. The first transverse plane can pass through the incisal point IP, i.e. the point of contact of the incisal edges of the two lower central incisors, which can be achieved in particular by using the Fibonacci sequence.

[0367] The order of the steps in Part B may be varied.

[0368] In part C after the ideal occlusal plane has been determined, regardless of the method used to determine the occlusal plane (e.g. CranioPlan (may be a trademark) or 3D structural markings by Saxler / Hornung), the following steps can be performed to produce one or more training devices in a kit of devices:

[0369] - In an eighth step following the seventh step, free spaces can be created in the digital data space for the teeth and / or dental implants of the upper and lower dental arches, so that the devices can then be precisely mounted on the respective dental arches without pinching or damaging the gums. Subtractive operations, in particular Boolean operations, can be used here. Marginal clearances can also be taken into account where applicable.

[0370] - In an optional eighth step, by digitizing the digital model defined in the eighth step, a precise definition of the position of the device and its two parts in the mouth can be achieved with the planned form fit only at specific support points between the device and the dental arch or at small support surfaces compared to, for example, tooth cracks. Alternatively, the edge clearance may not be used and a support of a larger area may be used.

[0371] - In a subsequent ninth step, the device can be manufactured in its parts and completely for the individual case and can then be used for that patient.

[0372] A method using a 3D structure marker (3D marker or 3D ruler) according to Saxler and Hornung is described in WO 2020 / 141134 A1, wherein no mention is made of a kit consisting of a device, in particular no mention is made of a kit consisting of an aligner or of a device having an alignment function. This document is incorporated herein by reference for all legal purposes.

[0373] Other methods can use facial features, in particular facial features that correspond to the above-mentioned bony features of the facial skull. This can reduce or completely avoid the radiation exposure caused by X-rays.

[0374] Methods using 3D structure markings (markers / rulers) can be performed manually, semi-automatically or automatically, in particular computer-assisted.

[0375] The determined occlusal plane can be identical in both methods (CranioPlan (can be a trademark), 3D marker / ruler), but does not have to be. In both methods, three spatial angles of the normal to the occlusal plane with the three coordinate axes of the Cartesian coordinate system and three position coordinates relative to the three coordinate axes can be considered, i.e. a total of 6 parameters.

[0376] In contrast to planes, in the above-mentioned "3D marker / ruler" method, the so-called Speech curve of the occlusal surface of the teeth can still be determined and / or taken into account. In this case, for example, the position of the teeth in the center of the right jaw (maxilla or mandible) or in the center of the right jaw (maxilla or mandible) will deviate, wherein the corresponding teeth can be arranged below the occlusal plane.

[0377] In other embodiments, the occlusal plane can be determined using methods other than the “CranioPlan” (which may be a trademark) according to Hornung (EP 3 332 731 A1) or the method according to Saxler, Hornung (3D structure marking, 3D marking, 3D ruler, WO 2020 / 141134 A1).

[0378] Alternatively, other suitable methods may be used to determine the target occlusal plane.

[0379] According to an embodiment, after wearing the last device or the last device pair, the final medical structure of the person's teeth and / or tooth roots can be achieved according to the treatment plan. The final medical structure can create a permanent occlusal surface that is consistent with the planned occlusal surface.

[0380] According to another aspect, a manufacturing method is provided, which is particularly used for manufacturing a kit according to one of the above embodiments or a device based on a kit designed according to one of the above methods. In the manufacturing method, a subtractive manufacturing method (preferably a cutting method, in particular milling) can be used to manufacture a kit consisting of a device or a device pair or at least for manufacturing a part of a device.

[0381] Alternatively, additive manufacturing methods, in particular 3D printing (three-dimensional printing), are used for producing a kit of devices or a pair of devices or at least for producing a part of a device.

[0382] The manufacturing method may involve an individually customized device for insertion into a (particularly human) mouth. The device may consist of or include at least one maxillary module and / or at least one mandibular module. The digital 3D model of the device may be positioned as a preform with orthogonal axes in a 3D model of a head with its orthogonal axes, so that the axes of the device (preform) are parallel to the axes of the head. The axes of the head may be generated primarily on the basis of markings of areas of the facial skull or of inner areas of the skull. By positioning, the positions of grooves may be generated, which grooves are generated in the preform for the teeth of the dental arches of the maxilla and mandible in the 3D digital model, for example in particular by subtraction or other methods of removing digital shapes, so that modules with these grooves are then generated using additive or subtractive manufacturing techniques.

[0383] The device can be designed in one country (first country) and manufactured in the same country or another country (second country). One or more devices can be worn or used, for example, in the first country, the second country or the third country. At least the first part of the kit can be quickly manufactured in the same country where the related device is also used, for example to avoid long and / or time-consuming transport routes. Another part of the same kit can be manufactured in another country, because the other part is not needed until later, so the longer transport distance becomes less important and the manufacturing cost reduction at the production site will be decisive.

[0384] Another aspect relates to a computer system comprising:

[0385] - at least one memory unit designed to store the instructions of the program, and

[0386] - A control unit, which is designed to execute instructions of a program, which instructions cause the computer to perform at least a part of the above method, in particular to perform steps related to the design of the device of the kit. Therefore, the above technical effects can also be applied to computer systems.

[0387] Another aspect relates to a computer program, which includes machine-readable instructions, which, when executed by a control unit, cause the control unit to perform at least a part of the method according to one of the above aspects or one of the above embodiments. Therefore, the above technical effects can also be applied to the computer program.

[0388] Another aspect relates to a computer program product, which includes machine-readable instructions, which, when executed by a control unit, cause the control unit to perform at least a portion of the method according to one of the above aspects or one of the above embodiments. Therefore, the above technical effects can also be applied to the computer program product.

[0389] Another aspect relates to digital data, in particular design data and / or manufacturing data of a device for manufacturing a kit or a device pair for manufacturing a kit using a manufacturing machine, which is generated using a method according to one of the above aspects or one of the above embodiments, or is required for the above manufacturing method. Therefore, the above technical effects can also be applied to digital data.

[0390] The digital data may describe a kit of devices for shifting the occlusal plane of a person. The digital data may describe at least two devices or at least two device pairs, which respectively include a jaw device (e.g. an upper jaw device and / or a lower jaw device) and are designed so that the devices or device pairs are worn by the person in sequence according to a predetermined order of the devices / device pairs.

[0391] The maxillary appliance may be designed so that it is placed on a dental arch in the upper jaw of a person.The mandibular appliance may be designed so that it is placed on a dental arch in the lower jaw of a person.

[0392] In at least one device, at least one jaw device may include at least one height element on a first side. On at least one height element, at least two contact areas may be constructed at different positions of the molar element. At least one additional contact area may be constructed on the second side of at least one jaw device. At least three contact areas may determine a plane. The plane may be different from the starting occlusal plane of the person or the current occlusal plane of the person with respect to its inclination changed by at least one height element in the frontal section and / or sagittal section and / or with respect to its height position changed by at least one height element. In at least another device of the kit, another inclination and / or another height position of the corresponding plane in the frontal section and / or sagittal section may be adjusted by at least one additional height element, which is different from at least one height element in the adjusted height. At least one height element or multiple height elements may adjust a height that is at least twice or at least three times the height of at least one device on at least one accommodating area for anterior teeth elements or canine elements.

[0393] The digital data may include data sets. Additionally or alternatively, a database structure may be used for structuring the digital data, in particular to facilitate access (reading and / or writing), for example when changing the digital data. Furthermore, a relational database may be used, for example, or the digital data may be described and / or stored in other suitable ways and methods.

[0394] The above-mentioned embodiments and improvements are also applicable to digital data.

[0395] Another aspect relates to treatment planning, in particular digital treatment planning for shifting the occlusal plane of a person, in particular when using a kit according to one of the above aspects or one of the above embodiments, or when using a method according to one of the above aspects or one of the above embodiments. The treatment plan may describe a course of dentistry and dental treatment of a person. The treatment plan may determine the following data at least in sub-parts or in the entire treatment plan:

[0396] - the number of the device pair of the set or the number of the set,

[0397] - identification of the tooth positions within the corresponding device pair, and

[0398] - determination of the treatment function for the respective tooth position of the respective pair of devices,

[0399] Therefore, the decision is made in at least three "dimensions", that is, respectively based on three parameters. On the one hand, this requires the processing of a larger amount of data, and on the other hand, it increases the flexibility of the treatment plan.

[0400] The kit mentioned in the treatment plan (ie the basis of the treatment plan) can be used to support the migration of the person's occlusal plane and / or perform other functions, in particular alignment functions and / or shifting operations.

[0401] The kit mentioned in the treatment plan may include at least two devices, at least five devices or at least ten devices. The devices may respectively include at least one jaw device. The at least one jaw device may respectively include an upper jaw device and / or a lower jaw device. The devices may be designed so that the devices are worn by the person according to the order predetermined in the treatment plan.

[0402] In at least one device, at least one jaw device may include at least one height element on a first side. At least two contact areas may be configured at different positions of the molar element at at least one height element. At least one additional contact area may be configured on the second side of at least one jaw device. At least three contact areas may determine a plane. The plane may be different from the starting occlusal plane of the person or the current occlusal plane of the person with respect to its inclination changed by at least one height element in a frontal section or a sagittal section and / or with respect to its height position changed by at least one height element. In at least another device in the kit, another inclination and / or another height position of the corresponding plane in the frontal section and / or the sagittal section may be adjusted by at least one additional height element, which is different from at least one height element in the adjusted height. At least one height element or multiple height elements may adjust a height that is at least twice or at least three times the height of at least one device on at least one accommodating area for anterior teeth elements or canine elements.

[0403] Thus, the treatment plan may allow a combination consisting of a shift of the occlusal plane and, for example, an alignment function. Thus, the above-described technical effects also apply to digital treatment planning.

[0404] The above-mentioned embodiments and improvements may also be applicable to treatment planning.

[0405] The digital treatment plan may include a data set. Additionally or alternatively, a database structure may be used for structuring the digital treatment plan, in particular to facilitate access (reading and / or writing), for example when changing the digital data. Furthermore, a relational database may be used, for example, or the digital treatment plan may be described and / or stored in other suitable ways and methods.

[0406] The digital treatment plan may, for example, be suitable and adaptable for submission to a dental or other health insurance company, such as to obtain approval prior to treatment and / or to obtain reimbursement from the insurance company during or at the conclusion of treatment.

[0407] In particular, digital therapeutic programs may include the following features:

[0408] - optionally quickly approaching a target occlusal plane or a training occlusal plane different from the target occlusal plane, e.g. with only one device or less than five devices or less than six devices, wherein preferably a significant shift of the occlusal plane is achieved according to a tooth plan, e.g. according to a quadrant plan, e.g. by at least 1 mm, at least 2 mm or at least 3 mm at at least one tooth position, and / or

[0409] - optionally "overshooting" the change, for example overshooting to a training occlusal plane and then returning to a target occlusal plane, the training occlusal plane being more different from the starting occlusal plane than the starting occlusal plane is from the target occlusal plane, and / or

[0410] - "overshoot" again in the other or opposite direction, for example to a mid-occlusal plane which differs less from the starting occlusal plane than the starting occlusal plane differs from the target occlusal plane.

[0411] Another aspect of the invention may relate to a training method in which a new occlusal plane is learned as described above.

[0412] Although the present invention has been described in detail by way of preferred embodiments, the present invention is not limited to the disclosed examples and those skilled in the art may derive other variations therefrom without departing from the scope of protection of the present invention.

[0447] The displacement function 220 may be shown in a device that is suitable or adapted to follow a larger plan to relocate teeth, preferably in a further larger construction of a dental arch or arch-shaped arrangement of tooth elements.

[0448] The shape function 230 may be shown at the device 10, where at least some of the dental veneers have an individual shape that is different from the shape of the real medical (where applicable) tooth or tooth root, for example:

[0449] - where the shape is reconstructed, and / or

[0450] - wherein the dental veneer covering the actual or underlying tooth / tooth element is larger and / or more voluminous than the underlying tooth, and / or

[0451] - where the veneer is longer, and / or

[0452] -Where the dental veneer has a different and more conformable shape than the tooth.

[0453] like Figure 1 As shown, the image visible from the outside can be generated or composed by the shape of the visible dental veneer. The proposed technology can be characterized in that the shape of the device 10 (as long as it is visible from the outside) changes little or not at all on the device or a part of the device of the kit 100, but changes in the covered area, in particular at the covered teeth.

[0454] When the device is outside the mouth of the person P, the professional can recognize the difference between the devices 10 at the faintly recognizable starting points of the alignment elements 13 during operation of the kit. However, changes to the dental set of the person P can occur either in the areas of the actual teeth of the dental set that are covered by one or more dental veneers or in the molar area that is not directly visible from the outside.

[0455] The treatment plan may generally include x stages, where x is the natural number mentioned above. The kit 100 may include x number of devices, one each for the maxillary OK, 5 and the mandibular UK, 4, i.e., a pair. The point of application of the interaction force between the device and the tooth may vary from device to device. Thus, the tooth may be gradually moved. Figure 1 The covered mounted force function element 13 is shown systematically in FIG.

[0456] It may be particularly meaningful if the device 10 is already optimized in shape and optionally in color in the integrated technology. For example, at a quick glance, the differences between the devices 10 of the set 100 cannot be seen from the external geometry and / or color. The differences between the devices 10 that follow one another may lie in particular at the front teeth covered by one or more dental veneers, in particular in the exact location of the recess into which the tooth intrudes, i.e., for example, in the functional element 13 that can exert a force on the tooth and in the free space provided for the tooth to move in reaction to this force F.

[0457] The movement of the teeth can take place behind the scenes following the treatment plan BP and is not directly recognizable from the outside. The last device 10 forms the end of the multifunctional alignment treatment. The complete set of teeth with teeth and roots in the new position can then be provided with the dental final treatment 300. The tactile and visual impression will only change slightly in the transition from the last device to the final treatment. In the final treatment 300, the teeth can be blocked as little as possible, because otherwise bone integration may be affected.

[0458] The device or device pair 10 of the kit 100 may be used by a person P (e.g., see Figure 8 and Fig.10 ) are worn in sequence. All or part of the device pair may include dental veneers. Dental veneers are marked with NI1.2, N.II.1.2, N.III.1.2, N.IV.1.2, NI1.2, etc. according to their position. The identification follows the tooth position identification used by dentists and orthodontists, that is, four quadrants or sectors I, II, III and IV are used, and the teeth in the quadrants are numbered from 1 to n from front to back relative to the reference system of person P. From the observer's perspective, quadrant I is located at the upper left, quadrant II is located at the upper right, quadrant III is located at the lower right, and quadrant IV is located at the lower left. Therefore, the quadrants can be displayed in a clockwise direction, that is, clockwise. The naming of dental veneers can be as follows:

[0459] - The first letter is N (replica, veneer), as opposed to Z for teeth or A for recesses,

[0460] - The Roman numeral in the second position indicates the quadrant, as above.

[0461] - the third digit indicates the position within the quadrant, and

[0462] The digit in the fourth position indicates the number of the relevant device in the sequence of devices 10 of the set 100 .

[0463] For example, the dental veneers NI1.2, N.II.1.2, N.III.1.2, and N.IV.1.2 are located in the first position or front position of the first quadrant I, the second quadrant II, the third quadrant III, and the fourth quadrant IV, respectively, in this order. Figure 1 As shown, the veneer position is located in the second device, which is indicated by the last number respectively. In the use state of the device 10.2, the corresponding tooth positions of the corresponding front teeth behind the dental veneer are ZI1.2, Z.II.1.2, Z.III.1.2 and Z.IV.1.1. The second tooth on the upper left as viewed from the observer has the marking ZI2.2, i.e. it is located in the second position of quadrant I in the device 10.2. Therefore, the relevant dental veneer or tooth replica is marked with NI2.2.

[0464] The number n can represent a device or device pair 10 in the middle part of the sequence or set 100, for example, see dental veneer NI2.n, which is located at the same position as dental veneer NI1.2 and can be designed the same as dental veneer NI1.2 on its outer face, in particular its front face. The three dots indicate that at least one further device pair, usually a plurality of device pairs, of the set 100 can be located between the third device pair 10.3 and the device pair 10.n.

[0465] The number x may denote the last device or device pair 10.x of a sequence or a set, for example, see dental veneer NI1.x, which may correspond to dental veneer NI1.2, NI1.n, i.e. have the same external shape and / or may be arranged in the same position relative to the upper dental arch of the device, in particular the maxillary device 11. The three dots again indicate that at least one further device pair, typically a plurality of device pairs, of the set 100 may be located between device pair 10.n and device pair 10.x.

[0466] The device parts that are located on the right side "re" of the device when viewed from the observer (dentist, technician, orthodontist) are located on the left side relative to the person wearing the device (device pair), which is indicated by "li (P)" in the figure. Similarly, the device parts that are located on the left side "li" of the device when viewed from the observer are located on the right side relative to the person wearing the device (device pair 10.1, etc.), which is indicated by "re (P)" in the figure.

[0467] therefore, Figure 1It is clearly shown that the front area of ​​the devices 10.1 to 10.x can remain unchanged, while the alignment function 210 of the devices is changed. Additionally or alternatively, the front area of ​​the devices 10.1 to 10.x can remain unchanged, while the structure in the molar area is changed, for example, the structure with the height function 250 and / or the sliding function 260 and / or the ramp function 270 is changed, for example, see the molar area in the first quadrant I, which can be different in the first device 10.1 than in the second device 10.2, and in the last device 10.x than in the middle device 10.n, see arrows P1 and P2.

[0468] Figure 2 A comparison alignment treatment plan BP2 for a number x of alignment splints S.1 to Sx is roughly schematically shown in a functional diagram. The functions included therein can be divided into an alignment function 210 and a displacement function 220. The alignment function 210 is used, for example, to better integrate individual teeth or groups of teeth into the basic dental arch.

[0469] The shifting function 220 is used, for example, to migrate or change the dental arch on a large scale, for example, in expanding the dental arch, so as to create more space. In many cases, the shifting function 220 can be used to carry out such expansion, so as to first enable alignment of existing teeth, i.e., to create the required space.

[0470] Since the alignment splint can also squeeze the tooth from the inside and thus tilt it outwards, there can be a certain degree of overlap between the alignment function 210 and the displacement function 220. Usually, a so-called attachment can correspond to an alignment element at a recess in the splint that accommodates the tooth, but this attachment is not mounted at the splint, but at the corresponding tooth. The area of ​​the tooth in the splint usually allows a certain mobility in the desired direction of the tooth migration. Therefore, success can be achieved within certain limits by combining the alignment function 210 with the displacement function 220 alone.

[0471] The sequence of splints can guide the teeth to a new situation, in particular those teeth that were initially very different from the target state can be displaced and / or twisted. After the alignment treatment using the last splint 10.x, the teeth are in a new formation, but they still look the same as before. Only then can the teeth be further treated in the final treatment 300 using aesthetic, dental and dental techniques, such as veneers and / or crowns and / or countertops. In this case, only then can the appearance of the teeth be changed, but it can be changed drastically at this time. Especially in the case of adult patients or people with a full set of worn and misaligned teeth, this type of alignment treatment may have obvious weaknesses and very limited effectiveness.

[0472] In the comparative example, the treatment plan BP2 may include only two sub-treatment plans BP2a and BP2b, which indicates that only a few functions are used in the comparative set S1-x consisting of devices or device pairs. In particular, the comparative set S1-x may not include the shape function 230, i.e., dental veneer. In contrast, the devices or device pairs S1, ..., Sn, ... Sx of the comparative set S1-x may be made of transparent or at least translucent materials.

[0473] Figure 3 The proposed multifunctional treatment plan BP3 is schematically shown. The kit 100 comprises a number x of devices 10. The kit 100 is built on an initial state 200 of a complete set of teeth. The first device of the kit 100 is the device 10.1 and the last device is the device 10.x. In the multifunctional treatment step of the kit 100, the state 10.x is reached with the device 10.x, i.e. the end of the treatment is reached with the splint or device. Then the final treatment 300 can be carried out.

[0474] By means of the multifunctional combination of these functional elements combined in a fully integrated manner in the kit 100 of the device 10, a simple alignment splint can be produced, for example according to Figure 2 Comparison of - multidisciplinary effects that cannot be achieved with the alignment splints S.1 to Sx. Starting from the state reached by the device 10, the final medical treatment 300 can then be carried out with the table top, veneer, etc., ie after the removal of the last splint 10.x.

[0475] With the color function 240 activated, the color selection can be pre-tested during the multifunctional treatment. In the embodiment shown, the alignment function 210 can extend over a large portion of the kit 100 as the tooth is displaced relative to its adjacent teeth, or as shown, over the entire kit 100. The devices 10.1 to 10.x then successively carry the appropriate alignment elements at the selected recesses or have the appropriate position or shape for the teeth to displace the selected teeth by contact forces and rotational or tilting moments combined with the required freedom of movement.

[0476] In the illustrated embodiment, multifunctional diversity comprises alignment function 210, shift function 220, shape function 230, color function 240, height function 250, sliding function 260, ramp function 270, implant function 280 and support function 290. The arrow along the function column shows that the function can be optionally activated, but it is not necessary to activate continuously in all devices. In general (not shown here), some functions in the current kit 100 just can not be activated, because female patients or male patients (people P) do not need this function. Especially rarely, namely only when there is implant, implant function 280 just may be activated.

[0477] It can be clearly seen that, for example, in the case of using dental veneers or dental replicas, the shape function 230 can be used from the beginning, i.e. in the first device 10.1 and / or in all devices 10.1 to 10.x. This can be relatively unproblematic in some treatment situations. In other cases, this can be supported or implemented by other suitable functions of the functions 210, 202, 240 to 290.

[0478] The use of dental veneers or veneer elements may be technically associated with the color function 240, so that transparent materials without dyeing and / or without white or other opaque coatings may not be suitable for bringing visual coverage functions. However, if the stability function and / or tactile function of the dental veneer or veneer element is sufficient or provides other sufficient advantages, transparent materials can be used, for example.

[0479] The color function 240 can be used optionally from the outset, i.e. in the first device 10.1 and / or in all devices 10.1 to 10.x. The color function 240 can also be optionally varied within the kit to find a suitable color tone or a suitable color gradient. The color function 240 can achieve colors that are different from transparent and / or translucent materials. Within this understanding, white is also considered a color, because white also fulfills the function of shielding or veneer.

[0480] The arrow in the shift function 220 which starts later indicates, for example, that an alignment is first performed before the shift function 220 is started in the device 10 . f.

[0481] The initially activated sliding function 260 means, for example, that in the molars the first device can carry a sliding device, while the subsequent ones no longer do. In contrast, in the molar region the height function 250 (height) is present continuously in the example, because, for example, the teeth are worn and a previous bite that was too deep must be corrected. In general, the functional elements implemented in the device 10 can differ between successive devices. A device 10.n may not only differ from the subsequent device 10.n+1 in the geometry of the force transmission element 13, but may also include a different combination of functional elements and functional types, but the exterior of the dental veneer may remain the same or unchanged.

[0482] An important feature is that the shape function 230 can also be used very early as a mechanical stabilization function, and where applicable as a biomechanical function or as an aesthetic function, and in accordance with Figure 2 No dental veneer is used in the comparison-alignment-treatment, so the shape and / or position of the recess does not change behind the dental veneer or in the dental veneer relative to the dental veneer that does not change in the front. The shape change is caused by the design of the dental veneer associated with the device 10, rather than by simple material deformation around the receiving portion or recess for receiving the tooth.

[0483] In this compact multifunctional illustration of the selected treatment plan BP3, it is noted that each column for each function can relate to a pattern of typically up to 32 teeth of a dental set. The view shown is therefore the sum of the teeth of the dental set. Activation of a function means that it is activated in the associated device in at least one tooth or at least one group of teeth. Figure 3 and Figure 4 The multifunctional "phases" shown, for a complete multifunctional treatment plan BP3 or BP4, also add dental "phases" associated with individual tooth positions (up to 32 tooth positions). This distribution of activations to the individual teeth is not shown here.

[0484] The treatment plan BP3 can be completed with final medical treatment 300, i.e., for example, by veneers and / or crowns or countertops, preferably oriented towards the final or target tooth state, i.e., oriented in accordance with the labial shape of the dental veneer NI1.1 etc. which is also oriented towards the final or target tooth state.

[0485] The treatment plan BP3 includes, for example, nine sub-treatment plans BP3a to BP3i, which correspond to the above-mentioned functions 210 to 290 in sequence.

[0486] Additional features may optionally be added, such as an orthosis feature 275, such as a Saxler orthosis, see WO2020141134A1, which is incorporated herein by reference for all legal purposes. The separation sliding plane of the orthosis can be determined according to Saxler (3D structure marker or marker or 3D ruler) or according to other methods. The orthosis can include edge gaps, but does not have to.

[0487] Figure 4 A treatment plan BP4 is shown for a special but also frequently occurring situation, which has no implant function 280 and no support function 290, but has a significant shape function 230, i.e. a shape function of a frontally visible dental veneer, for example, of a splint, and / or a color function 240, i.e. a color design of a frontally visible dental veneer, for example, of a splint, in particular a color design different from a transparent and / or translucent color design.

[0488] In this case, the maxillary splint 11 is positioned in a direct clamping manner on the teeth of the maxillary OK, 5, and the mandibular splint 12 is positioned in a direct clamping manner on the teeth of the mandibular UK, 4. A gradual, subsequent alignment function 210 with tooth migration and orientation is then used for the position of the final treatment 300. At the same time, as required, in the case shown, a stage of a displacement function 220 occurs in the middle area of ​​the sequence, in which the teeth are moved outwards, for example. This displacement function 220 would be more significant in other cases. This displacement function 220 can generally be a prerequisite for having sufficient space so that the teeth can be individually designed in shape and size accordingly in the final stage 300 (final treatment) after the multifunctional treatment by the kit 100.

[0489] The step-by-step, subsequent alignment function 210 is illustrated by a plurality of arrows to illustrate the Figure 3 The complexity of the alignment is increased. Therefore, during the treatment planning BP4, the alignment may involve different teeth.

[0490] The shape function 230 can also be staged, as illustrated by a plurality of arrows, for example, so that there is no sudden movement from an initial state to a final state, i.e., so that, for example, an enlargement of the dental arch is not immediately visible and thus not clearly visible to all, but is staged and thus inconspicuous to third parties and to the person P. Thus, the shape function 230 (veneer) does not have to be oriented to the final target tooth state from the outset. Intermediate target tooth states can be used. Alternatively, in the treatment plan BP4, a shape function 230 that remains unchanged or is only slightly changed can also be used, using the associated tooth veneers and / or tooth replicas.

[0491] exist Figure 4 In the embodiment shown, other features may also be optionally added, such as an orthosis feature 275, such as a Saxler orthosis, see WO2020141134A1, which is incorporated herein by reference for all legal purposes. The separation sliding plane of the orthosis can be determined according to Saxler (3D structure marker or 3D marker or 3D ruler) or according to other methods. The orthosis can include edge gaps, but it does not have to.

[0492] exist Figure 4 In the example, the optional color function 240 is shown to be activated in stages in an arrow sequence so as not to suddenly move from an initial state to an optimized brighter state, for example from a yellower coloration to a whiter or white coloration. Alternatively, a color function 240 that remains unchanged or substantially unchanged can also be used in the treatment plan BP4, for example, the color can only be changed within the scope of manufacturing possibilities and / or manufacturing tolerances.

[0493] Also in Figure 4 In, with Figure 3 Likewise, the height function 250 is continuously activated because the tooth is worn in the initial state 200. The sequence of arrows along the function column 250 shows that structures of different heights are used successively or successively in the molar region.

[0494] The sliding function 260 is illustrated in stages on the devices or device pairs 10 . 1 to 10 . x , for example in the molar region by means of a sliding region.

[0495] The ramp function 270 will be additionally activated periodically, in particular when the biomechanics of the jaw joint require it, for example in the second half of the kit 100.

[0496] Functions 280 (implants) and 290 (supports) may not be applicable, for example, because they involve a complete set of teeth that still contains all teeth or only a few teeth are missing. Alternatively, functions 280 (implants) and 290 (supports) can also be used in BP4 treatment planning and thus also in the devices of kit 100.

[0497] The sequence shown here serves only as an explanation aid. This correct sequence for a given patient or person P can be determined based on the initial state and with the help of the planned target state. In any case, however, even for complex misalignments and wear situations, the multifunctional treatment offers many more treatment possibilities than before. The target group can be patients or persons P between the ages of 30 and 80, i.e. this target group can be very large. Since functional advantages, especially in terms of aesthetics and / or tactile sensations, are considered decisive, the patient's willingness to invest can be very high. In particular in patients over the age of 50, and in particular in persons over the age of 60, due to wear, it is usually meaningless to use, for example, only a pure alignment treatment such as the alignment function 210 and, where applicable, also the shifting function 220.

[0498] The treatment plan BP4 includes sub-treatment plans BP4a to BP4i, which correspond to the above-mentioned functions 210 to 290 in sequence.

[0499] Figure 5 In the upper figure, a mandibular portion 12 is shown as part of a device or a device pair 10 . Figure 5 a shows a first device component 12 from a first stage of the kit 100, Figure 5 b shows a second device component 12 from a second phase or second sub-portion of the kit 100 .

[0500] Figure 5 a In the molar region, the sliding surface 15 is indicated by the number 15. This can be a feature of an activated height function 250 in combination with an activated sliding function 260.

[0501] exist Figure 5 In b, the height function 250 is still activated, but the sliding function 260 is not activated. Instead, the ramp function 270 is activated in the form of a small but effective ramp at the teeth in the molar area. This can be seen in the contact surface 16, which is designed in a protruding manner with inclined flanks and a small ramp (see arrow P5). These move the mandible UK, 4 laterally forward during occlusal contact and therefore have a completely different effect than the sliding function 260 at the same occlusal height.

[0502] exist Figure 5 a and Figure 5 In b, the front teeth are veneered and covered by the dental veneer 19 associated with the mandibular splint 12. The displacement of the actual teeth thus takes place in a covered manner. In the area of ​​the front teeth, the dental veneer 19, which is also aesthetically designed, forms the covering. In this case, the alignment function 210 and the displacement function 220 are installed in the recesses for the teeth, entirely according to the needs of the individual and the period. However, this can only be seen when the splint is taken out of the mouth. In the area of ​​the molars, the structures 15 and 16 cover the teeth. However, this can only be seen from the outside, for example, when the mouth is opened to a large extent.

[0503] Figure 6 The schematic diagram shows different states of the device 10 , for example, taken from a kit 100 , wherein only the mandibular splint 12 is shown in each case. The maxillary splint is omitted in each case for a better illustration of the molar region.

[0504] Figure 6 a shows a starting state 50 of the teeth of a person P or patient. Figure 6 a shows an abnormality in the state of the teeth, which is usually caused by classic orthodontic measures, i.e., for example, after the extraction of two teeth in the lower jaw. As a result, the undersized dental arch in the lower jaw is not widened, for example. This promotes the wear of the teeth. In this case, the state of the jaw joint is usually poor and craniomandibular dysfunction (CMD) may often occur. The jaw joint and the occlusal plane may then also require treatment.

[0505] according to Figure 6 b, the first mandibular splint 12.1 is located on the full set of teeth in the starting state 50, but the first mandibular splint already shows the shape function 230 at the tooth veneers 19 designed to be larger, the front teeth are located behind and / or below these tooth veneers. Figure 6 a Compared to the anterior teeth, the anterior teeth appear to no longer require treatment, even though they require treatment and are being treated.

[0506] Starting from the splint 12.1 in the initial state 50, there can be a period in the multifunctional treatment plan BP and the corresponding number of devices, in which a raised sliding surface 15 is installed in the right and / or left molar area 56 / 57. The sliding surface can be mainly flat or part of a hypersurface. The sliding surface can thus form a sliding function 260. The degree of the heightening gives the height of the height function 250. The contact surface in the molar area can also include ramps and steps or different ramps of the ramp function 270.

[0507] According to the vector force decomposition, the contact in the slope and / or inclined plane can cause the force component of the occlusal muscles to act on the mandibular UK, 4, so that a transverse or anterior-posterior directed force component is generated. This can achieve a change in the contact force in the jaw joint, and the mandibular UK, 4 can be displaced or twisted relative to the maxillary UK, 5.

[0508] In a specific embodiment, the asymmetrical arrangement of the sliding surfaces 15 and the ramps 17 in the right and left molar region can be selected to enable complex position corrections consisting of translations and torsions (for example, with a total of 6 degrees of freedom), see in particular Figure 6 c.

[0509] The intermediate or ultimate goal of multifunctional therapy can be Figure 6 d shows a state 60 with a wider dental arch and a larger dental veneer 19. At the same time, for example, especially in the molar area, the occlusal plane can be correctly adjusted biomechanically and misalignments in the jaw joint can be corrected. All these different treatment goals can be jointly achieved simultaneously in the device 10 of the kit 100, wherein the series of devices 10 are respectively composed of an upper jaw splint 11 and a lower jaw splint 12.

[0510] Figure 7 Roughly schematically, a relatively high structure 15 (such as Figure 7 a) can be used in particular in the molar region to firstly enable the lateral mobility of the mandible and / or secondly to form a sliding surface with a functional type 60 (sliding). The structure 15 can also be referred to as a thickening or as a height element. The structure 15 can be completely filled with material, i.e. the structure 15 is solid. Alternatively, the structure 15 can also include a cavity in its interior, in particular when mechanical stability is to be ensured. The cavity can, for example, reduce the mass of the device.

[0511] In the contact state, lateral mobility of the teeth may be necessary in order to be able to move the teeth better and / or without collisions by means of the alignment function 210 (positioning function) and / or by means of the displacement function 220. In contrast, if, for example, Figure 2If, like the comparative aligner shown, the occlusal plane is covered with a layer having a relatively uniform layer thickness, neither a sliding surface is formed nor a release of mobility occurs.

[0512] Figure 7 b shows a specific variant that initially uses thinner structures and very quickly introduces taller structures (e.g. Figure 7 a) may cause discomfort. Therefore, the height of the structure required for treatment can be increased or decreased as needed. Figure 7 The state of b gradually increases to Figure 7 The state of a. Figure 7 Status b can already lead to a certain degree of relief for the jaw joint.

[0513] The direction of the mandibular displacement can be adjusted by means of bevels in the detailed design of the contact surface 16 between the maxillary OK, 5 and the mandibular UK, 4. At the same time, the alignment function 210 and the displacement function 220 may already be realized and used within a narrower range.

[0514] for Figure 7 In the case shown in a, it may be necessary that the structures of the maxillary OK, 5 on the depicted side can be implemented in terms of strength to be weaker than in the mandibular UK, 4. This is useful, for example, when the occlusal plane is non-physiologically inclined and / or should be shifted according to the skull or skull analysis of the skull symmetry conditions in the skull of the patient P. Such complex shapes of the devices for the maxillary OK, 5 and the mandibular UK, 4 cannot be produced, for example, by deep drawing. However, such complex shapes can be produced by additive manufacturing, such as 3D printing, or subtractive manufacturing, such as milling.

[0515] The structures 15 may be bilaterally symmetrical or asymmetrical with respect to each other.

[0516] Figure 8 A section through the jaw or also through the jaw joint of a patient P is clearly and schematically shown, the patient wearing a device consisting of two parts 11 and 12, which can have specific features. The device can include or contain an occlusal ramp 17 in the molar area and a sliding surface 15 also in the molar area. When the mandibular UK, 4 and its sliding surface 15 move backward along the front axis, contact occurs at the occlusal ramp 17 in the dotted circle. This hinders the backward movement of the mandibular UK, 4 and thus prevents the backward compression of the jaw joint 5, see arrow P8a.

[0517] For example, the height of the occlusal ramp 17 and the sliding surface 15 is adjusted so that an upward compression of the jaw joint 5 is also prevented, see arrow P8b. As a result, the muscles can be stretched and the jaw joint is relaxed. If the sliding surface 15 is designed to have different heights and the position and pattern of the ramp 17 are designed to be asymmetrical on the right and left, a shift of the occlusal plane, in particular a change in the inclination of the occlusal plane, occurs as long as the device is worn.

[0518] Since the final treatment 300 may be planned to be installed after the last device 10 , such an optimized position of the occlusal plane may be prepared with the aid of a multifunctional treatment and a kit 100 of devices, enabling such a physiologically favorable position to be achieved in the final treatment 100 .

[0519] If the structural and correction functions 250, 260, 270 cannot be performed at all due to the use of conventional alignment devices, i.e. alignment devices without a high level of structure, then the complex final treatment 300 has to be performed in the old, non-physiological position of the occlusal plane. Otherwise, the suddenly changed occlusal plane would then be a burden on the patient, which could also be disadvantageous for the already completed final treatment 300, since the new position of the occlusal plane cannot be adapted to. This could, for example, lead to the destruction or damage of the final treatment 300, i.e., the destruction or damage of, for example, a crown or the like. In contrast, by means of a structural stepwise change of the occlusal plane and / or skull optimization, treatment effects are achieved that were previously not possible or were only possible in or with significantly longer treatment times.

[0520] Detailed observation, Figure 8 A typical situation is shown schematically, such as can occur as a late consequence after the extraction of four premolars in orthodontic treatment. Due to the misalignment, severe wear and even loss of the normal alignment of the teeth, for example in terms of the Spee curve, can occur. In this case, the teeth must not only be displaced or can be displaced by a tilting moment, but are also subject to elongation, i.e. moved upwards or downwards, so that, for example, the section protruding from the gum is "elongated". This can be achieved by means of a corresponding relief area for the teeth in the upper jaw, which has free space for a solidly constructed maxillary splint (not shown, for the mandibular device 12 see Fig.12 ).

[0521] Fig. 9 Shown in accordance with Fig. 9 a and Fig. 9 Cross-section through the mandibular device 12 for the mandibular UK, 4 in the two cases following each other. Fig. 9In a, in particular the incisor 51 is twisted and not optimally positioned. Although the outer contour of the device 12 remains essentially unchanged, the teeth 51a, 52a, 53a, etc. on the left side of the lower dental arch of the person P and the teeth 51b, 52b, 53b, etc. on the right side of the lower dental arch of the person P are covered by the dental veneer of the device and are moved inside or behind the dental veneer by the alignment function 210. In this case, the free space that the teeth can occupy is gradually transferred from one device to another relative to the dental veneer visible from the outside.

[0522] This makes it possible to reproduce the final shape and final appearance of the complete set of teeth viewed from the outside very quickly or at an early stage, while the alignment covered by the veneer area of ​​the device can continue. Fig. 9 The molars in a are too close to each other, especially on the right side, and are too far forward, see offset V9a. This is probably because the lower left molar was extracted at a young age, and later the wisdom tooth on the left closed the dental gap, while the lower right wisdom tooth was extracted.

[0523] Fig. 9 b shows the situation after successful migration of the anterior teeth by the alignment function 210 combined with successful large-scale displacement of the molars by the displacement function 220 of the widening dental arch. In addition, the right-left offset of the proximal molars 57a and 57b can be reduced, that is, the offset V9b is significantly smaller than the offset V9a, for example, less than half of the offset V9a, or even less than a quarter of the offset V9a.

[0524] As can be clearly seen from the shadow outline of the splint in the cross-sectional view, the shape of the dental veneer of the splint 12 visible from the outside, especially from the front, does not change significantly. The displacement of the teeth can usually be carried out in a covered manner. At the same time, the height function 250 and / or the sliding function 260 and / or the ramp function 270 required in the applicable case are not shown or cannot be shown in the cross-sectional view.

[0525] Fig.10 A comparative example of an alignment splint made, for example, of a deep-drawn, nearly transparent thermoplastic film material is shown. A frontal face of a mandibular incisor is shown through, the incisor having the splint located thereon. Fig.10a shows an initial state S.1 in which the incisors (i.e. the right anterior tooth Z.IV.1.1 as viewed from person P and the left anterior tooth Z.III.1.1 as viewed from person P) are too far apart from one another, wherein the last digit indicates the position of the respective tooth at the point in time when the device with the same number was first placed on the tooth. It can be seen how the almost transparent covering follows the contour of the tooth, wherein a small free space is provided in each case for the intended migration of the incisor 51 shown to the middle, see for example the free space FR10a. On the pressing side, there is a force transmission contact area 13 in each case. As a force transmission element 13, an active surface can be used, which can act directly on the tooth 51 or indirectly on the tooth 51 via an attachment (not shown). Fig.10 a shows the resulting force vector F from left to right to indicate the direction of the left-right displacement of tooth 51, Z.IV.1.1.

[0526] Fig.10 b shows the same teeth Z.IV.1.n, Z.III.1.n after further migration to the mid-sagittal plane SE. The gap between the incisors 51 or the anterior teeth is closed. The almost transparent splint gradually covers the teeth and follows the incisors 51 that are formed and moved. This comparison-alignment-technique is characterized by a substantially identical thickness of the deep-drawn film that partially covers the teeth and / or a relatively consistent imitation of the shape of the recesses at the outer shape of the device.

[0527] Fig.10 a also shows the occlusal region O.IV.1.1 above the tooth Z.IV.1.1 and the occlusal region O.III.1.1 above the tooth Z.IV.1.1. The occlusal region O.IV.1.1 forms an upper covering for the recess A.IV.1.1 of the tooth Z.IV.1.1. In contrast, the occlusal region O.III.1.1 forms a covering for the recess A.III.1.1 of the tooth Z.III.1.1.

[0528] Fig.10 b also shows the occlusal area O.IV.1.n above the tooth Z.IV.1.n, which is identical to the tooth Z.IV.1.1 but has a different position and / or inclination, and the occlusal area O.III.1.n above the tooth Z.III.1.n, which is identical to the tooth Z.III.1.1 but has a different position and / or inclination, and the tooth Z.III.1.n which is identical to the tooth Z.III.1.1 but has a different position and inclination.

[0529] Axis A10.1a Fig.10The original position of the tooth Z.IV.1.1 is shown in a. The axis A10.2a shows the original position of the tooth Z.III.1.1. The occlusal area O.IV.1.1 has, for example, a maximum width B10.1a. The occlusal area O.IV.1.1 has, for example, a maximum width B10.2a. The labial outer surface or the lingually oriented surface of the device can also have a similar maximum width at the wall of the recess A.IV.1.1 or A.III.1.1. For example, the distance D10.1a (spacing) is located between the occlusal area O.IV.1.1 and O.III.1.1. For example, the distance D10.2a is located between the recess A.IV.1.1 and A.III.1.1.

[0530] Axis A10.1a and A10.2a are also Fig.10 b to illustrate the change in the position of tooth 51. From the observer's perspective, tooth Z.IV.1.n is relative to Fig.10 The position of the same tooth Z.IV.1.1 in a is shifted to the right. From the observer's perspective, the tooth Z.III.1.n is relative to Fig.10 The position of the same tooth Z.III.1.1 in a is shifted to the left.

[0531] For example, the occlusal region O.IV.1.n has a maximum width B10.1b, which is approximately equal to the width B.10.1a. For example, the occlusal region O.III.1.n has a maximum width B10.2b, which is approximately equal to the width B.10.2a. The labial (outwardly facing) or lingual (inwardly facing) oriented face of the device may also have a similar maximum width in the region of the recess A.IV.1.n or A.III.1.n. The widths B10.1b and B10.2b may remain constant, since the device Sn is also manufactured in a deep-drawing process, the tooth 51 does not change in its width, and therefore the tooth replica in the mold used for deep-drawing does not change either.

[0532] For example, the distance D10.1b (distance) is located between the occlusal areas O.IV.1.n and O.III.1.n. The distance D10.1b is smaller than the distance D10.1a due to the deep drawing process which depicts a smaller distance between the teeth 51. The same applies to the distances of the labial sides at the walls of the recesses A.IV.1.n and A.III.1.n.

[0533] The distance D10.2b (distance) between the recesses A.IV.1.n and A.III.1.n can be as large as the distance D10.2a, which is also determined by the deep-drawing process. The free space FR10b in the recess A.IV.1.n is much smaller than the corresponding free space FR10a in the recess A.IV.1.1. It should be noted that the deep-drawing process is carried out around a model (deep-drawing die) of the tooth 51, wherein the model (deep-drawing die) is extended around the area where the free spaces FR10a, FR10b, etc. are located later.

[0534] Fig.11 The results show that the difference between the anterior teeth and the comparative example (see Fig.10 ) Different embodiments. The mandibular splints 12.1 and 12.n are made of or include a polymer, for example, which preferably has an aesthetic, high-quality appearance similar to dentin and enamel, ie is also shiny, but preferably not transparent. Fig.11 The front teeth 51 that are still too far apart in a should be moved so that they are relatively closer to each other, but only to the extent that a larger dental veneer or restoration of the front teeth is not required in the final completion period or final medical period 300. The dental veneer is formed early in the treatment by one or more splints 12.

[0535] exist Fig.11 In a, the shape of the incisor or anterior tooth 51 (tooth veneer, tooth replica) is already significantly larger than the partially worn tooth 51, especially in the occlusal direction. This is because the shape of the tooth 51 or the tooth veneer is larger than the tooth 51 according to Fig.10 The comparative example of splint S.1 or Sn is realized by extending the area beyond the incisor further. In the visible area, the incisor 51 is mostly or completely covered by the dental veneer.

[0536] The splint 12.1 shows a force-transmitting contact area 13 between the recess of the splint and the tooth 51 or at the recess. Thus, the tooth 51 is displaced so that the teeth 51 are brought closer and closer to each other, see for example the force vector F. Here, if one observes in detail, the recess for the tooth to be displaced is displaced relative to the almost unchanged dental veneer forming the splint 12.1 or included in the splint 12.1. In this stepwise displacement of the recess for the tooth, the wall thickness of the splint in the vicinity of the tooth to be displaced changes, see distance / spacing D11.2a and distance / spacing D11.2b. In the direction of further displacement, the displacement free space is respectively recreated and the contact area 13 is respectively redirected so that a moment can be applied to the tooth again in the subsequent splint.

[0537] Fig.11b shows a tooth 51 that has been moved at a smaller distance. Here, the dental veneer, such as N.IV.1.n and N.III.1.n, is larger than the tooth 51 or Z.IV.1.n and Z.III.1.n, in particular, larger than the area of ​​the tooth 51 that is not in the gums. However, the dental veneer or tooth replica, such as N.IV.1.n and N.III.1.n, preferably looks like a tooth.

[0538] and Fig.10 Compared to b, the distance of the teeth 51 may preferably be larger, because more space is needed or may be needed for a larger dental veneer. The proposed embodiment may be characterized in that a dental veneer larger than the teeth forms the front section of the splint and covers a recess inside the splint, which accommodates the teeth and provides a contact force, which moves stepwise relative to the dental veneer in the direction in which the teeth should migrate, so that the teeth migrate relative to the dental veneer of the splint. It may also be characterized in that Fig.10 Compared to the comparative example in the , the dental veneer is embodied significantly longer, for example in order to restore the original length or a length exceeding it for worn teeth. Neither of these features occurs in the comparison-alignment-splint.

[0539] Thus, the free space FR11 a may be much narrower than the free space FR10 a , for example because other manufacturing techniques are used, such as subtractive or additive manufacturing techniques, instead of deep drawing processes (pressure, vacuum and / or temperature).

[0540] Fig.11 a shows the resulting force vector F from left to right to indicate the direction of the left-right displacement of tooth 51, Z.IV.1.1.

[0541] Fig.11 a also shows the occlusal area of ​​the dental veneer N.IV.1.1 above the tooth Z.IV.1.1 and the occlusal area of ​​the dental veneer N.III.1.1 above the tooth Z.IV.1.1. The occlusal area of ​​the dental veneer N.IV.1.1 forms an upper covering for the recess A.IV.1.1 of the tooth Z.IV.1.1. The occlusal area of ​​the dental veneer N.III.1.1 forms a covering for the recess A.III.1.1 of the tooth Z.III.1.1.

[0542] Fig.11 b also shows the occlusal area of ​​the dental veneer N.IV.1.n above the tooth Z.IV.1.n and the occlusal area of ​​the dental veneer N.III.1.n above the tooth Z.III.1.n, the tooth Z.IV.1.n being identical to the tooth Z.IV.1.1 but having a different position and / or inclination, and the tooth Z.III.1.n being identical to the tooth Z.III.1.1 but having a different position and inclination.

[0543] exist Fig.11 In a, axis A11.1a shows the original position of tooth Z.IV.1.1. Axis A11.2a shows the original position of tooth Z.III.1.1. The occlusal area of ​​dental veneer N.IV.1.1 has, for example, a maximum width B11.1a. The occlusal area of ​​dental veneer N.IV.1.1 has, for example, a maximum width B11.2a. The labial (outward) or lingual (inward) oriented surface of the device may also have a similar maximum width on the wall of recess A.IV.1.1 or A.III.1.1. The distance D11.1a (spacing) is, for example, located between the occlusal areas N.IV.1.1 and N.III.1.1 of the dental veneer. The distance D11.2a is located between recess A.IV.1.1 and A.III.1.1.

[0544] Axis A11.1a and A11.2a are also Fig.11 b to illustrate the change in the position of tooth 51. From the observer's perspective, tooth Z.IV.1.n is relative to Fig.11 The position of the same tooth Z.IV.1.1 in a is shifted to the right. From the observer's perspective, the tooth Z.III.1.n is relative to Fig.11 The position of the same tooth Z.III.1.1 in a is shifted to the left.

[0545] For example, the occlusal region of the dental veneer N.IV.1.n has a maximum width B11.1b, which is approximately equal to the width B.11.1a. For example, the occlusal region of the dental veneer N.III.1.n has a maximum width B11.2b, which is approximately equal to the width B.11.2a. The labial or lingually oriented face of the device 12.n may also have a similar maximum width in the region of the recess A.IV.1.n or A.III.1.n. The widths of B11.1b and B11.2b may be unchanged, since the dental veneer already has a target shape or an enlarged shape.

[0546] For example, the distance D11.1b (distance) is located between the occlusal areas of the veneers N.IV.1.n and N.III.1.n. The distance D11.1b is equal to the distance D11.1a, because the veneers or tooth replicas N.IV.1.1, N.III.1.1, N.IV.1.n and N.III.1.n already have their target shape and are no longer changed in the front area and / or the occlusal area and / or the lingual area. The same applies to the distances of the labial and / or lingual sides of the recesses A.IV.1.1, A.III.1.1, A.IV.1.n and A.III.1.n.

[0547] The distance D11.2b (pitch) between recesses A.IV.1.n and A.III.1.n may be smaller than D11.2a, as described above, for example due to a more precise manufacturing process rather than a deep drawing process. The free space FR11b in recess A.IV.1.n may be smaller than or equal to the corresponding free space FR11a in recess A.IV.1.1.

[0548] Fig.11 The devices 12.1 and 12.n shown and preferably all other devices of the same kit 100 can be manufactured by a subtractive manufacturing process (e.g. milling) or by an additive printing process (e.g. 3D printing), which, compared to deep drawing processes, in particular allows for the production of greater variations in layer thicknesses of occlusal surfaces or other surfaces (e.g. labial sides, lingual sides) and / or allows for the production of undercuts, for example in the superior-inferior direction relative to the teeth of person P.

[0549] Fig.12 Shown are sections through the molars and anterior teeth in two different, successively succeeding stages of treatment with the proposed splint in the example of the mandible UK, 4.

[0550] Fig.12 a shows a splint with a high structure (eg with a sliding surface 15) in the molar region of the lower jaw (UK, not shown), which surrounds a molar 56 that is too low. This molar is to be moved upwards. Fig.12 In a, above the molar 56, there is an unfilled cavity in the recess, into which the molar 56 can move. In the region of the front teeth 51, outgrowth is also possible when the forces are directed accordingly.

[0551] therefore, Fig.12 b shows a later state still with the sliding surface 15, in which the molar 56 has grown into the recess in the splint 12. The front teeth 51 that are also growing outwards may require that the splint 12 has a deeper recess, into which the teeth 51 that are higher up and thus larger above the gums can be inserted. A feature here can be that Fig.12 In the present invention, the teeth are moved without changing the outer contour of the device 10 or the mandibular splint 12 shown here. The different wall thicknesses required for the splint 12 or the device 10 are achieved by suitable manufacturing processes, for example by precision machining of polymer materials or by 3D printing. Fig.12 What is not shown is that during treatment the position of the teeth may also be shifted laterally and the axis of the teeth may also be tilted, for example simultaneously with or alternating with the lifting.

[0552] and Fig.12 Compared with a, Fig.12b, the same teeth Z12a, Z12b are displaced upwards, see horizontal lines H1, H2. The outer contour of the device 12 can remain unchanged here, see the position of the tooth veneers N12a, N12b in the front area of ​​the device 12 and / or the sliding surface 15 in the molar area of ​​the device 12 relative to the line H1.

[0553] Therefore, the distance D12a or D12b corresponding to the layer thickness of the dental veneer N12a or N12b in the front area can be reduced, wherein the position of the dental veneer N12a or N12b relative to the horizontal lines H1, H2 does not change, and / or the outer shape / contour of the dental veneer N12a or N12b, especially in the front area, does not change or changes only slightly.

[0554] Fig.13 Two variants of the design of dental veneers 19 , N13a , N13b which appear identical when viewed from the outside are shown in the anterior region. Fig.13 a shows a structure made of solid material, wherein the outer contour is formed by the material of the visible dental veneer N13a, while the inner contour of the material forms the receiving area for the tooth Z13a. As a movement stimulus, the inner surface in the recess can exert local forces and moments on the tooth Z13a.

[0555] Fig.13 b shows the same arrangement from the outside. However, in this partial view the device consists of two materials in two areas. Fig.13 The cross-sectional view of FIG. 1 shows in the outer region a dental veneer 19, N13b which is preferably composed of an aesthetically pleasing, attractive material, in particular of a non-transparent material. A larger recess is required inside the region 19, N13b composed of such a material compared to the tooth Z13b. This larger recess is partially filled with a second material so that a suitable recess for the tooth Z13b remains. The filling 18 located inside can be softer or harder than the outer shell of the dental veneer 19. In a special embodiment, the outer dental veneer region via the successively following devices 10.n, 10.n+1, etc. remains unchanged, and only the shape of the recess for the tooth in the filling region 18 of the device changes. A section through the mandibular device 12 is shown respectively, but the same variant can also be applied to the maxillary device 11.

[0556] A narrow free space FR13a may be located between the tooth Z13a and the bottom of the dental veneer 19, N13a, which may also be referred to as a tooth replica / veneer element. Similarly, a narrow free space FR13b may exist between the tooth Z13b and the bottom of the dental veneer 18, 19, N13b (particularly the bottom of the inner material of the dental veneer 18, 19, N13b). The dental veneer 13b may also be referred to as a tooth replica / veneer element, because the tooth replica / veneer element, together with the tooth Z13b, replicates the target tooth state of the tooth Z13b.

[0557] Fig.14 Three optional steps in a kit 100 of a device or device pair 10 are shown, in particular the mandibular devices 12.1, 12.n and 12.x, in particular the incisors Z14a, Z14b and Z14c in sections in three successively following steps of a migration that can be referred to as a shifting function 220. The purpose of such a migration is, for example, to enlarge the dental arch by pushing the teeth further outward. Since the teeth are firmly fixed in the jaw with their roots, a shift (which can also be referred to as a migration) can be a tilting of the teeth around a low tilting axis and at the same time an adaptation of the dental veneer in its dimensions (extension) and / or orientation, if observed carefully. In the shifting function 220, it is proposed no longer to tilt the teeth only, but to shift the dental veneer or veneer element and to adapt it in size. The recess for the actual tooth 51 can be changed in terms of tilt by exerting a force significantly above the tilting axis. With the placement of the splint, the replicas N14a, N14b, N14c of the restored teeth 51 then appear shifted, although the actual teeth 51 are tilted in the covered area. Compared to a purely directly visible tilting of the teeth outwards, the displacement of replicas N14a, N14b, N14c and the corresponding restorations such as the last replica N14c may be more suitable visually or functionally when the teeth are too inwards, unless the teeth were already too inwards tilted in the initial state.

[0558] The same tooth Z14a to Z14c is shown in three different positions, wherein a dental veneer N14a to N14c is used, whose outer contour, in particular the front outer contour, can be unchanged or remain the same. The axes A14a to A14c show the above-mentioned inclination about the inclination axis, which is Fig.14 Vertically to the page.

[0559] The section St14a, St14b or St14c from the center line of the dental veneer (tooth replica) N14a or N14b to a vertical reference line, which may lie in the tilt axis, for example, increases continuously and corresponds to the respective forward expansion or displacement of the dental veneer N14a to N14b.

[0560] Material layer thicknesses D14a, D14b, D14c show the layer thicknesses of the front regions of the dental veneers (veneer elements) N14a, N14b and N14c. Compared to layer thickness D14c, layer thickness D14b is reduced, for example, because the reduction in layer thickness caused by the inclination of tooth Z14b is greater than the increase in layer thickness caused by the displacement of dental veneer N14b. Layer thickness D14c is the same as layer thickness D14c, for example, because the reduction in layer thickness caused by the inclination of tooth Z14c is equal to the increase in layer thickness caused by the displacement of dental veneer N14c relative to the vertical reference line.

[0561] Fig.15 A special case of the intermediate period is roughly schematically shown, in which the device 10.n consists of an upper jaw splint 11.n and a lower jaw splint 12.n. In the contact between the lower jaw UK, 4 and the upper jaw OK, 5, the ramp-shaped functional element 17.n generates a force component that is lateral and / or anteroposteriorly directed as a ramp function 270. In the example shown, an excessive forward movement of the lower jaw UK, 4 is specifically prevented in the misalignment known as mandibular retraction (Sunday-Bite). The ramp 17.n in the device 10.n can be positioned and oriented in different ways relative to the molars 56, 57 in order to gradually and carefully move the lower jaw UK, 4 backward to a new static position. At the same time, a strong overheight portion with a height function 250 and a distinct sliding surface with a sliding function 260 can be integrated. Therefore, the high structure in the molar area can be very strong or very high, so that the lower jaw UK, 4 also maintains contact bite in the actual static equilibrium position. It can be seen in the jaw joint head 6 that the jaw joint head 6 is sufficiently far from the rear wall 7 of the jaw joint in the upper jaw, see distance D15. The rearward displacement of the lower jaw by the ramp function 270 is therefore a targeted measure. Only by the rearward displacement of the lower jaw in combination with a pronounced height function 250 with a solid or hollow structure in the molar area can a heavy cross bite, for example, be relieved.

[0562] Fig.15The situation in an intermediate stage of the kit 100 is shown, in which the lower incisors 51, 52 have been brought behind the upper incisors. There is an example here in which it can make sense to keep the teeth of the mandibular UK, 4 small first and then reconstruct them as part of one or more splints by appropriately sized and appropriately shaped dental veneers when they have reached the correct position. In fact, in the shortest possible state, the front teeth 51 / 52 of the mandibular UK, 4 can be more easily migrated backwards from the wrong bite below the upper incisors. In contrast, in the maxillary OK, 5, treatment can be carried out from the beginning or from the beginning by means of the shape function 230 and the optional color function 240. At the end of the multifunctional treatment with x devices, it can also be planned to remove the last device 10.x according to the treatment plan BP. Then, it can be planned to implement the final medical treatment 300 with veneers, countertops, etc., while the position of the occlusal plane is preferably selected cranial and the height of the structure above the teeth that still exist can be maintained.

[0575] In the following, further embodiments of a kit consisting of devices are explained, which enable the position of the occlusal plane to be relearned, preferably neuromuscularly. Figures 1 to 16 Alternatively, other embodiments may also be independent of Figures 1 to 16 The embodiment of use.

[0576] A method of making a multifunctional dental device is described. In a preferred embodiment, the multifunctional device 10.n may not only have an alignment function 210, optionally with or without accessories. Additionally or alternatively, the multifunctional device may also have a function of adjusting a new bite plane or allowing neuromuscular learning of the position of a new bite plane. Thus, the device may have a recognizable feature that allows relearning the position of a new bite plane.

[0577] The goal of the set 100 of the device 10 can be to arrange the teeth in the dental arch more aesthetically and / or medically more rationally, to control misalignments, to enlarge the tooth bodies where necessary and / or to adjust an occlusal plane or a target denture plane or a target dentition plane that is as optimal as possible in terms of physiological craniosynthesis, for example, according to the method of "CranioPlan" (possibly a registered trademark) or Hornung. For this purpose, a contact plane can be used, which forms a systematic separation plane between the maxillary part 11 and the mandibular part 12 of the device 10.

[0578] The position of the new contact plane can be determined, for example, by first determining the ideal position of the contact plane or occlusal plane from the digital data of the skull. For this purpose, several alternative methods are available. In this document, for example, the method "CranioPlan" according to Hornung (possibly a registered trademark) (EP 3 332 731 A1) and the 3D marking or 3D ruler method according to Saxler-Hornung (WO 2020 / 14134 A1) are explained in more detail.

[0579] The document EP 3 332 731 A1 is incorporated herein by reference for all legal purposes. In addition, the document WO 2020 / 141134 A1 is also incorporated herein by reference for all legal purposes.

[0580] However, this ideal position may not be fully achieved due to the anatomical accommodation limitations present in the jaw joint, which may result, for example, in a unilateral dislocation of the jaw joint. In this case, an ideal position can be generated that is as close as possible to the maxillary-mandibular (OK-UK) contact plane, so that the jaw joint can be stressed as anatomically correctly as possible.

[0581] The method may be represented or implemented by computer-implemented techniques.

[0582] 1. Input or input data can be the following digital data:

[0583] 3D (three-dimensional) image recordings, preferably voxel data (voxel-volume elements) of the material density of the head, for example voxel data of a complete set of teeth, eye sockets and right and left inner ears.

[0584] - Alternatively, but probably not sufficient, it is possible to use scan data (sampling) from an intraoral scanner for 3D reconstruction, which may be very important for the reproduction of the gingiva.

[0585] 2. The ideal target contact plane / occlusal plane can be determined by:

[0586] -2a) X-ray data can be segmented into teeth, bones and gums.

[0587] -2b) The teeth of maxillary OK and mandibular UK can constitute a complete set of teeth (dentition) in the initial state.

[0588] -2c) In the initial state, the set of teeth can be assigned a starting contact plane 310, SKE for maxillary-mandibular OK-UK contact (chewing). Therefore, a pentagonal flat virtual / digital surface can be suitable,

[0589] -2d) From the digital data of the anatomical structure of the skull, the ideal position of the ideal contact plane 350, IKE can be derived, i.e. it can be determined where the ideal contact plane 350, IKE should be located, if this is possible. For example, a virtual / digital 3D CranoPlan (possibly a registered trademark) construction according to Hornung (EP 3 332 731 A1) can be performed, or a virtual / digital 3D ruler according to Saxler Hornung (WO 2020 / 14134 A1) can be fitted to the digital data of the skull.

[0590] 3. The actual target contact plane 330, ZKE can be determined by:

[0591] -3a) can determine the freedom of movement of the mandibular UK relative to the maxillary OK in the jaw joint,

[0592] -3b) Starting contact plane 310, SKE can migrate towards the ideal contact plane by interpolation until at least one stopping condition is satisfied in the jaw joint,

[0593] - 3c) This stop contact plane or an approximation thereof can be used as target contact plane 330 , ZKE for the construction of the kit 100 of the device 10 .

[0594] 4. The calculation method for devices 10.1 ... 10.x can be as follows:

[0595] 4a) The transition from the starting contact plane 310 to the target contact plane 330, ZKE can be carried out very quickly, for example in less than 40% of x stages or steps, preferably in a maximum of 5 stages, until the target contact level 330, ZKE is reached, particularly preferably in a maximum of 3 stages.

[0596] -4b) Optionally, in a further stage, a number y of stages may first be exaggerated to the position of the training contact plane 340, TKE. The training contact plane 340, TKE may be suitable for performing specific stretching and movement training of the jaw joint and / or for relearning the position of an easier occlusal plane, for example compared to training using the target contact plane 330, ZKE. During the training, the person P may respectively tense the masticatory muscles around an unstable equilibrium position until a lateral disengagement or lateral movement of the mandible relative to the maxilla occurs. Alternatively or additionally, if one or more devices 10 are kept in the mouth during a meal, the training may be performed implicitly during chewing.

[0597] -4c) A single target contact plane 330, ZKE can then be set for the device 10.n, for example a target contact plane 330, ZKE consisting of an upper jaw device 11 and a lower jaw device 12, for example by the arrangement of a shaped body or a dental veneer (one or more veneer elements), which is replaced by the person's still usable teeth at the end of the treatment, or in the final medical treatment 300 by a corresponding denture, for example a denture such as a model cast denture, a sleeve denture, an attachment denture, an implant-supported denture (such as a rod-type denture, a snap-in denture), a veneer, an inlay, a crown, an artificial tooth, a dental implant, etc.

[0598] 5. The transition to subsequent care (e.g., final care 300) can be done as follows:

[0599] -5a) At the end of the treatment, the dental and / or aesthetic medicine of the individual teeth, bridges or implants can preferably be performed so that the target contact plane 330, ZKE is set as close as possible, or if it becomes possible in between, even a better plane can be set, for example, it can be located closer to the ideal contact plane 350, IKE, or at a new ideal contact plane 360, IKE II.

[0600] -5b) For this purpose, a new cranial analysis can be performed. This can lead to new results and a new ideal contact plane 360, IKE II, since the cranial condition and / or the anatomy of the mandibular joint can change only slightly over a few months in the case of load changes, for example.

[0601] It may include using methods and devices or programs (software), for example, as explained in DE 10 2012 002 817 B4 (Knorr, Hornung). This document is incorporated herein by reference for all legal purposes. For example, the following digital volume tomography (DVT) imaging (images) may be used:

[0602] - Acteon Whitefox - Patient positioning in sitting or standing position: Cylinder, 599 images, FOV (Field of View) 60mm (millimeter) x 60mm, 80mm x 80mm, Resolution 0.15μm (micrometer), 105kV (kilovolt), 9mA (milliamp), Pulsed, Dental scan 360° (degrees), 25 seconds, Active 6.8 seconds, Focal spot 0.5, Manufacturer: Satelec (Acteon Group) - de Götzen – Milano.

[0603] - NewTom 5G - Patient positioning in supine position: Cylinder, 659 images, FOV 60mm x 60mm, 80mm x80mm, Resolution 0.125μm, 110 kV, 16 mA, Pulsed, Dental scan 360°, 36 sec, Active 7.3 sec, Focal spot 0.3, Manufacturer: QR srl - Verona IT.

[0604] During the image acquisition process, digital DICOM (Digital Imaging and Communications in Medicine, may be a trademark) data may be generated.

[0605] For segmentation (object masking) of 3D-DICOM data sets, 3D software can be used, such as the OnDemand3DTMApp program (version 1.0 or higher). OnDemand3DTMApp allows the management of medical 2D (two-dimensional) and 3D (three-dimensional) images. A wide range of 2D and 3D tools are provided for data analysis, formatting and segmentation.

[0606] In order to be able to segment (object mask) data representing tissue structures or the like (e.g. air, fat tissue, water, bone, root elements, dentin, enamel and other materials present in a complete tooth) by means of the Hounsfield density range, a calibration of the DVT device according to the Hounsfield scale may be necessary. Each voxel can then be uniquely assigned in this way to a value in the range of -1000 to +3000 Hounsfield. For example, the value for air is -1000 Hounsfield, for fat tissue -100 Hounsfield, for water 0 Hounsfield, for bone 500 to 1500 Hounsfield; for implants and enamel 3000 Hounsfield. Different values ​​can be highlighted by different colors.

[0607] The individual STL files (originally Stereolithography, now also other distributions) or other suitable formats (such as VRML (Virtual Reality Modeling Language), SLP, OBJ, etc.) can then be read or imported into other software, such as 3D-Tool Version 10 Basic or other programs. The 3D-Tool software or other programs can be used for professional data preparation for rapid manufacturing at a later stage, in particular for the production of rapid prototypes. An alternative CAD program is, for example, the Blender program.

[0608] Methods that can be used for rapid manufacturing (also called rapid prototyping) can include methods that start directly from a virtual (digital) computer-generated model and produce the corresponding real model. Examples of such methods include milling processes (such as contour milling processes) or generative and additive manufacturing processes (3D printers, laser sintering, stereolithography methods).

[0609] The final data set can be transferred to a milling machine, such as a Girrbach (may be a registered trademark) milling machine, to manufacture the denture.

[0610] The specific operation details of using digital tooth data and / or skull data to generate digital data for describing the device have been described above or will be described later, such as Boolean subtraction, intersection formation, etc. These methods are basically known to those skilled in the art, so they are only mentioned here without detailed description.

[0611] The difference between the starting contact plane 310, SKE, the target contact plane 330, ZKE and the ideal contact plane 350, IKE can be described as follows. The starting contact plane 310, SKE can be given by the current contact between the maxillary OK and the mandibular UK in the starting state. The first device in the kit can contain the starting contact plane 310, SKE. In other embodiments, the first device of the kit can already contain a contact plane that deviates from the starting contact plane 310, SKE.

[0612] If the occlusion is significantly misaligned, the initial contact plane 310, SKE, may shift unphysiologically, i.e. not in accordance with the normal life course. As a result, the occlusion may be dysplastic or malocclusal, such as deep overbite or crossbite. The jaw joint may be subjected to undue loads, has adapted to this state, and is therefore no longer optimally configured.

[0613] The ideal contact plane 350, IKE can be adjusted according to the existing skull and its biomechanics. This is possible even if the mandible is not in an adjusted ideal state.

[0614] The target contact plane 330, ZKE, can be as close to the ideal contact plane as possible without affecting the jaw joint. The training contact plane 340, TKE, can be set temporarily. This creates the effect of a bulky orthosis.

[0615] The following illustrations are already known and are derived from WO 202 / 141134 A1. This document is incorporated by reference into the present application for all legal purposes. The training contact plane is also tilted in two dimensions relative to the starting contact plane, but only a single orthosis is produced there, not a set of devices with possible additional functions and further shifted planes / occlusal planes. The following illustrations may be a bit too explicit. In practice, it is usually only possible to shift by a few millimeters or even less.

[0616] A relatively fast migration in the training contact plane, at least for example a migration of a few millimeters, for example a migration of 2 mm to 5 mm, can be performed to achieve a relearning of muscle function and neurophysiology during training. Therefore, from a functional point of view, a fast and slightly exaggerated migration of the occlusal plane can be important in order to set the target position after, for example, n=19 devices 10 and to maintain it until the final device of, for example, 10.24 or 10.25, see for example Fig.19 Description.

[0617] Fig.17 A device 10 for shifting the occlusal plane is shown with a training function for relearning the position of the occlusal plane. Fig.17 The upper part of the diagram shows two small schematic diagrams, and the lower part shows a rough schematic diagram with the mandibular UK, 4 and the maxillary OK, 5 and the inserted device 10, 1300, i.e., the details of the device 10 itself are not shown, because the focus is on the positioning of the contact plane. The device 10, 1300 can include sliding contacts that allow, for example, the upper jaw device 11 of the device 10, 1300 to slide sideways relative to the lower jaw device 12 of the device 10, 1300. In addition, the device 10, 1300 can also include at least one further dental technical additional function or multiple dental technical additional functions, such as in combination with the upper Figure 1 Functions 210 to 290 are explained.

[0618] exist Fig.17 c, that is Fig.17In the lower half of the figure, the original contact plane 310 of the cross-section of the teeth 56 / 57 can be seen. The cross-section can be identified through the mandible UK, 4 and the nasal region of the skull 1, 1200. The symmetry plane 2, 1250 and the symmetry structure 3 of the skull are marked, which symmetry structure depends in particular on the position of the eyes / eye sockets and / or zygomatic bones and the position of the right and left inner ear regions. Suitable features of the inner ear region include inner ear bones and / or parts of the balance organs, acceleration sensing organs, eardrums, cochleas or other significant areas or anatomical landmarks.

[0619] In this example, the set training contact plane 340, TKE is the same as the ideal contact plane 350, IKE, which is located perpendicular to the sagittal symmetry plane and the vertical symmetry axis 2, 1250. Fig.17 When observing the positions of the mandibles in c, it can be seen that these mandibles are approximately at the same height on the ideal contact plane, while the initial contact plane 310 and SKE are tilted relative to it.

[0620] If, for example, the training contact plane 340, TKE deviates greatly from the starting contact plane 310, SKE so as to "jump", i.e., necessary changes to the device 10 having the contact planes at the positions of planes 340, 350 would cause discomfort to the patient, or if there are other reasons, a less deviated contact plane 330 (not shown) may be provided, the less deviated contact plane being located between the starting contact plane 310, SKE and the training contact plane 340, TKE.

[0621] Fig.17 The training device 10 , 1300 is shown in detail with a separating sliding plane 1301 , TGE or a training contact plane 340 , TGE shown in a roughly schematic diagram at the position of the ideal occlusal plane. Fig.17 a schematically shows the skeletal structure of the skull 1, 1200 with the maxilla OK, 5, 1220 and the skeletal structure of the mandible UK, 4, 1230 adjacent to but not part of the skull 1, 1200. The dental arch 1221 of the maxilla OK, 5, 1220 and the dental arch 1231 of the mandible UK, 4, 1230 are covered by the device 10, 1300. The skeletal structure of the skull 1200, in particular the area around the eyes rather than the maxilla itself, can be analyzed to define the position and orientation of the main axes of the training device 10, 1300. Critical is the transverse axis 1215, see e.g. Fig.18 , and the vertical axis 1250 and the front-to-back axis 1205 which is not visible from the front, see also Fig.18 .

[0622] Fig.17b schematically shows a side view of the skeletal structure of the skull 1, 1200 (skull) in virtual 3D space, wherein the head is tilted forward enough so that the front-back axis 1205 of the skull 1200 extends horizontally in the image. The transverse right-left axis 1215 is in Fig.17 b is perpendicular to the image, i.e., perpendicular to the image plane outward or perpendicular to the image plane inward. The idealized occlusal plane 1201 is defined by these two axes 1205 and 1215 and is perpendicular to the vertical axis 1250 and contains the axis 1205. The separation sliding plane 1301, the training contact plane 340 of the TGE or device 10, 1300 can be precisely positioned so that the separation sliding plane 1301, the training contact plane 340 of the TGE or device 10, 1300 coincides with the idealized chewing plane 1201.

[0623] In a cross-sectional or side view, the anterior-posterior axis 1305 of the device 10,1300 is located on the anterior-posterior axis 1205 of the skull 2,1200. The vertical axis 1350 of the device 10,1300 is parallel to the vertical axis 1250 of the skull 2,1200.

[0624] Fig.17 c shows the superposition of Fig.17 c shows a front view of the outline of the device 10, 1300 with the separating sliding plane 1301, TGE or the training contact surface 340, TKE in a frontal section. The separating sliding plane 1301 or the training contact plane 340 is located as accurately as possible on the idealized chewing plane 1201 or the ideal contact plane 350, IKE. Fig.17 c illustrates the biomechanically and neurophysiologically important position and orientation of the separating sliding plane 1301 or the training contact plane 340, TKE between the upper part 11, 1320 and the lower part 12, 1330 of the device 10, 1300. In practical application, if the device parts 11, 1320 and 12, 1330 are manufactured exactly according to the dental arch, the separating sliding plane 1301 or the training contact plane 340, TKE will be uniquely formed due to the form fit of the device parts 11, 1320 and 12, 1330 used. The device 10, 1300 can be, for example, a training device or an orthosis, for example, the device 10, 1300 has additional dental functions 210 to 290. The device 10, 1300 with at least two parts 11, 1320 and 12, 330 can also be unilaterally asymmetrical and / or manufactured from multiple parts. The device 10 with at least two components 11, 1320 and 12, 330 can also be a device in a kit 100, which can include at least one training device or multiple training devices. Multiple devices 10 in the kit 100 can also have sliding contact areas that allow sliding movements, in particular sliding surface areas or other sliding contact areas.

[0625] When planning and manufacturing the device 10, 1300, in particular for jaw joint muscle training or jaw joint therapy, the transverse plane T1 of the 3D structure marker (3D Marker) 500 can be used as a reference plane, which is different from the transverse direction 1216 of the current occlusal plane and is aligned with the cross-sectional direction 1215. The direction of the anterior-posterior axis 1205 can also be located in the transverse plane T1. This can be an idealized occlusal plane T1a or a reference plane T1a, so that this plane is the plane in which the mandibular UK, 4, 1230 can perform lateral sliding movement relative to the maxillary OK, 5, 1220 when the device 10, 1300 is used.

[0626] In a two-part device 10, 1300 with a separating sliding plane 1301 or a training contact plane 340, TKE, for this purpose, when planning in a digital or virtual three-dimensional space, a preferred method is to orient a digital or virtual preform (preform) for the production of the components 11, 1320 and 12, 1330, or to orient the device 10, 1300 with a separating sliding plane 1301 virtually so that the separating sliding plane 1301 or the training contact plane 340, TKE of the device is in the direction of the idealized occlusal plane 340, 1201, IKE. In a particularly preferred embodiment, the separating sliding plane 1301, 340, TGE, TKE is identical in its angular orientation and vertical position to the transverse plane T1 or the reference plane T1a determined from the three-dimensional structure marking 500.

[0627] Fig.18 A schematic side view of a digital image of a head or skull 1, 1200 is shown in which a digital device 10, 1300 for shifting an occlusal plane is used. Fig.18 The head is schematically shown from the side and spatially positioned so that the coordinate system 1, 1200 of the skull is located vertically. In this spatial orientation, the anterior-posterior main direction 1105 of the occlusal plane 110 is at an oblique angle to the lateral main direction 1205 of the skull 1, 1200, while the separating sliding planes 1301, 340, TGE, TKE are positioned along this lateral main direction. The lateral main direction 1305 of the device 10, 1300 is therefore generated by appropriately positioning the preform or the entire preform in the 3D image space of the main direction 205 of the skull, so as to generate, for example, a training device as a contour of the preform and a contour of the dental arch together with an air gap by performing a Boolean operation using the digital data of the teeth and the digital data of the preform. Such operations are common in 3D software, for example called subtraction, intersection, etc. The same applies to the alignment of the other two spatial angles seen from the front and top, but not from the side. The role of the optional air gap or gap has been explained above. The gap in Fig.23If further occlusal clearance is required, the optional, substantially point-like contact points of the device 10, 1300 on the teeth can be supplemented manually, semi-automatically or automatically by a CAD (computer-aided design) program.

[0628] Fig.19 A part of a treatment plan BP19 is shown, which concerns a sequence of stages for migrating the function of the occlusal plane or allowing a preferably neuromuscular relearning of the function of the occlusal plane. Fig.19 The stages are shown for a suite 100 consisting of an apparatus 10. From a starting state a target state 10.x is reached which should be reached at the apparatus 10.x.

[0629] Fig.19 The downward pointing axis in the coordinate system shown in the figure represents the devices 10 of the kit 100 in order. In this embodiment, there are 24 devices (10.1 to 10.24). In other embodiments, there may be x devices in the kit 100, where x may be greater than or equal to 25, for example. Kits with fewer than 20 or fewer than 24 devices may also be used. The rightward dimension or Fig.19 The axis pointing to the right in the coordinate system shown represents the degree of inclination of the contact plane with respect to the initial contact plane 310. This degree may, for example, include a spatial angle, such as angle W1 or W2 or W3. Or this degree may also include multiple spatial angles, such as W1 and W2. In other examples, the degree may also additionally or alternatively relate to the position coordinates of the occlusal plane and / or a rotation around the normal of the occlusal plane, such as causing the midline position of the teeth of the dental arch to change.

[0630] The position of the contact plane in the initial state is indicated by the initial contact plane 310, SKE. The position of the ideal contact plane 350, IKE is also indicated. The ideal contact plane 350, IKE can be derived from the symmetry of the skull, for example, see Fig.17 The contact planes 320.1, 320.2, 320.3, 320.4 set in the devices 10.1, 10.2, 10.3 and 10.4 are quickly adjusted to an angle inclination or position 340, i.e. on the training contact plane 340, TKE, to effectively reprogram the neuromuscular function controlling the bite muscles. The devices 10.1, 10.2, 10.3 and 10.4 can have sliding contact areas and other dental technology additional functions.

[0631] This allows learning of movement patterns corresponding to the target contact plane 330, ZKE, in particular rapid learning. Fig.19In the embodiment shown, the ideal contact plane 350, IKE is not set, because this would cause the jaw joint to overload its fibrous structure and cartilage. After the training period, starting from device 10.n, a target contact plane 330, ZKE is set, for example n is 19, the position of which is significantly different from the starting contact plane 310, SKE, but from a cranial perspective, it is not as ideal as the ideal contact plane 350, IKE. This may be due to the fact that the jaw joint area has been significantly deformed. Devices 10.n to 10.x may no longer include an optional sliding contact area.

[0632] There are also cases where the target contact plane ZKE can be set to the ideal contact plane 350, IKE, especially when the deviation of the starting occlusal plane 310, SKE is not large. Therefore, in another embodiment, the ideal contact plane 350, IKE is set because the jaw joint in its fiber structure and in its cartilage allows this setting.

[0633] Specifically, Fig.19 The process shown is as follows:

[0634] 1) In the first period PH1: from the arrangement AOA (device 10.1) or the contact plane 320.1, via the arrangement AOB (device 10.2) or the contact plane 320.2, via the arrangement AOC (device 10.3) or the contact plane (320.3), to the training contact plane 340, TKE in the arrangement AOD (device 10.4), wherein the deviation from the starting occlusal plane or the starting contact plane increases continuously and with Fig.19 Compared with the overall process shown, the changes are rapid. Fig.19 In the process shown, the training contact plane 340, TKE is set closer to the ideal contact plane 350 than the target contact plane 330, ZKE, which is manifested as an overshoot US1. In another embodiment, it is possible to set directly to the target contact plane 330, ZKE, wherein there can then be a training phase, for example, whose length can be similar to Fig.19The training phase PH2 shown is the same and can even be longer. It is assumed here that the devices 10.1, 10.2, etc. are worn according to a predetermined schedule, for example replaced every week or every two weeks. The devices 10.1, 10.2, 10.3 and 10.4 can have sliding contact areas and other dental technical additional functions, but this is not necessary. The contact area or sliding contact area can be changed, in particular with respect to the arrangement of the receiving area of ​​the teeth or tooth elements in the devices 10.1, 10.2, 10.3 and 10.4, because the training sliding plane TGE or TKE should be changed. Alternatively, no sliding contact area can be used in the devices 10.1, 10.2, 10.3 and 10.4 or in some of them, even if this is the case, the occlusal plane or contact plane can still be shifted as described because, for example, uneven contact areas are used.

[0635] 2) In the second period PH2: The AOD arrangement is retained, for example in the device 10.5 to 10.13. In the second period, the training contact plane TKE is therefore used for the neuromuscular (re)training of the bite muscles. If the device 10.5 to 10.13 remains in the mouth during the meal, the training can be implicitly carried out in the bite. Deliberate training can be carried out in a supplementary or alternative way. The training duration is, for example, 10 minutes to 1 hour per day, wherein the training time can also be divided into multiple training periods per day. During the training period, exercises can be carried out according to a predetermined exercise plan.

[0636] Devices 10.5 to 10.13 may have sliding contact areas and other dental technology additional functions. The sliding contact areas may remain unchanged because the training sliding planes TGE or TKE should remain unchanged. The dental technology additional functions 210 to 290 of devices 10.5 to 10.13 or at least some of the dental technology additional functions 210 to 290 may be different from each other. On the other hand, these devices may also have dental technology additional functions that remain unchanged, such as a shape function 230 (tooth veneer / veneer element) and / or a color function 240. Unchanged functions may also have appeared in devices 10.1 to 10.4, but this is not necessary. There may be edge gaps in devices 10.5 to 10.13, which are conducive to neuromuscular relearning of the position of the occlusal plane, for example.

[0637] Alternatively, contact areas are used during the training period instead of sliding contact areas, which allow no sliding or relatively limited sliding, i.e. for example uneven contact areas between the upper jaw and the lower jaw or between an upper jaw device and a lower jaw device or between one of these devices and a tooth / tooth element on the opposite side fixed directly to the jawbone.

[0638] 3) In the third period PH3: the contact plane will be moved back again, wherein the contact plane can be directly adjusted to the target contact plane 330, ZKE, or as Fig.19 As shown, relative to the position of the target contact plane 330, ZKE and the overshoot US1, an overshoot US2 is performed in another direction. The overshoot US2 is, for example, smaller than the overshoot US1, but may also be the same or larger. There may be medical or other reasons for using overshoot US2, such as solving similar problems such as occlusal interference of teeth. The migration can be performed by arranging AOE (device 10.14) to arranging AOF (device 10.15), wherein the arrangement AOF may also remain unchanged in devices 10.16 and 10.17. Finally, the arrangement AOF can be transitioned to the arrangement AOG corresponding to the position of the target contact plane 330, ZKE, for example using two devices 10.18 and 10.19. Devices 10.13 to 10.19 may include sliding contact areas, but this is not necessary. Sliding can simplify neuromuscular relearning of, for example, the position of the occlusal plane. Optional edge gaps can also facilitate neuromuscular relearning, particularly relearning related to the sliding plane.

[0639] Alternatively, in the third period PH3, contact areas can also be used instead of sliding contact areas, which allow no sliding or relatively limited sliding, i.e., for example, uneven contact areas between the upper jaw and the lower jaw or uneven contact areas between the upper jaw device and the lower jaw device or uneven contact areas between one of these devices and the tooth / tooth element on the opposite side directly fixed to the jawbone.

[0640] 4) In the fourth period PH4: the contact plane of AO6 can be maintained, see for example devices 10.20 to 10.24, where device 10.24 can be the last device 10.x in the kit 100. In the fourth period, training may no longer be required. Therefore, devices 10.19 to 10.24 can implement the alignment function 210 or other functions 220 to 290. Devices 10.19 to 10.24 may not include a sliding contact area. Alternatively, devices 10.19 to 10.24 or a portion thereof may include a sliding contact area.

[0641] Fig.19The chronological sequence is shown, first the digitally and then the planes / occlusal planes actually executed in conjunction with the dental arch and appliances 11, 12. The illustration shows the planes / occlusal planes used in the 3D design (to the right) and the consecutive numbering of appliances 11, 12 (towards). It is important to note that the actual effective occlusal plane can only be formed when appliances 11, 12 are placed on the dental arch, for example, if only mandibular appliances are used as planned and not maxillary appliances, the biomechanical and neurophysiological effect of the currently generated occlusal plane will not be as expected in the plan. The thick black line indicates the planned trajectory, i.e. in the first few appliance pairs, the occlusal plane is quickly and drastically migrated, where the teeth may not or cannot follow so quickly.

[0642] In the first phase PH1, for example, the occlusal surface of the device facing the opposite side is raised and the device is thickened, preferentially in the molar area, i.e. here height elements are used. At the same time, the veneers in the incisor and canine area can be made larger and longer, as long as this change does not hinder the remodeling of the tooth structure. This quickly produces an aesthetic effect similar to the treatment result. The device is very comfortable to wear - especially when the jaw joint is not damaged - and due to its aesthetic advantages, it is highly accepted by the patient P and is not removed unplanned. This seemingly unimportant point is crucial for the correct sequence. Because if the device is removed unplanned, progress will be significantly delayed and may even lead to rebound and interference problems. It has been shown that the aesthetic or functional design of the anterior teeth and canines also provides great advantages in terms of food intake, because the optimized shape of the teeth also greatly improves the bite. Unlike orthotics, the device does not need to be removed for food intake. However, it needs to be cleaned like third-party teeth.

[0643] If during the actual treatment, the migration of the tooth deviates from the planned tooth position, the pre-calculated 3D contours of the devices 11, 12 will no longer be suitable. In this case, once the real position of the tooth is accurately acquired again, a new 3D calculation of the devices 11, 12 can be performed. This can then serve as a new starting point for the subsequent method. In this case, the previous occlusal plane is not completely aligned, but this does not cause a noticeable disturbance and at most only causes some delays.

[0644] Fig. 20 A parasagittal section parallel to the middle or median sagittal plane Sm is shown through a device, such as device 10.4 for shifting the occlusal plane. Device 10.4 comprises a maxillary part 11 and a mandibular part 12 as a device pair, as well as a receiving area 1134 for teeth of OK, 5, 1220 and for teeth of UK, 4, 1230.

[0645] Fig. 22 The protrusions shown above may be optional.

[0646] The contact plane provided in the device 10.4 is a training sliding plane 340, and in the case shown, the contact surface is flat and smooth, without a ramp function. This is a special case in which the device 10.4 achieves a significant orthotic function 275. This is a training state in which the contact plane 340 deviates greatly from the starting contact plane 310. The target contact plane 330 deviates less from the starting contact plane in the embodiment shown. The black area is a section through the material of the device 10.4. The teeth of the mandible can in certain cases protrude into the material of the maxillary component.

[0647] Fig. 20 The training device 10.4 with a larger inclination angle in the full set of teeth is shown from the side, see e.g. Fig.18 The side view shows that the separating sliding plane 110 of the device 10.4 is not exactly located in the occlusal plane 111, for example, the initial occlusal plane 310, SKE. Compared with the occlusal plane 111, 310, SKE, the separating sliding plane 110 is located lower at the rear (right side in the figure) molar.

[0648] The molars of the mandible can extend far into the region of the maxillary part 11. Therefore, an optional correction of the training device may be necessary. The correction can be a parallel displacement of the transverse plane or the separation sliding plane 110, TGE, TKE upwards or downwards parallel to the plane T1, so that the wall thickness of the remaining processed preform / preform reaches the minimum value that can be manufactured, or the penetration of the teeth on the opposite side is not too large, or the wall thickness on the training device reaches an appropriate thickness. The sliding direction of the front view and the side view will not change due to the upward and downward displacement of the transverse plane. Alternatively, no additional displacement is required.

[0649] The protrusion 1125 in the shape of a hill (or a platform) can be used as a support point or support area in the maxillary device 11 and contact the teeth or tooth elements of the maxillary OK, 5. The protrusion 1135 in the shape of a hill (or a platform) can be used as a support point or support area in the mandibular device 12 and contact the teeth or tooth elements of the mandibular UK, 4. The protrusions 1125, 1135 can have approximately the same height, so that they can also reflect the contours of the receiving areas 1124, 1125.

[0650] The distance between the contact surface at the protrusion 1125 and the training sliding plane TGK may be defined as a difference D1.

[0651] If edge gap 1122 is not used (see e.g. Fig. 22 and Fig.23), and for example, therefore also without using an occlusal gap, the projections 1125 and 1135 can be omitted, since with the projection 1125 the material of the upper jaw device 11 would extend over the entire occlusal area up to the teeth / tooth elements, and with the projection 1135 the material of the lower jaw device 11 would extend over the entire chewing area up to the teeth / tooth elements. However, the arrangement of the receiving areas 1124, 1125 to the training sliding plane TGK can remain essentially unchanged.

[0652] Fig.21 A parasagittal section through a device (eg, 10.1) for shifting an occlusal plane is shown, wherein the device (eg, 10.1) is placed in the order of the devices 10 of a kit (eg, 100), for example, at Fig. 20 The device 10.4 is shown from the front.

[0653] Device 10.1 includes protrusions 1125, which correspond to protrusions 1125 of device 10.4 and are, for example, located at the same tooth position as protrusions 1125 of device 10.4. Device 10.1 also includes protrusions 1135, which correspond to protrusions 1135 of device 10.4 and are, for example, located at the same tooth position as protrusions 1125 of device 10.4.

[0654] The distance between the contact surface at the protrusion 1125 and the training sliding plane TGK (see Fig.21 The double arrow in the figure can be defined as the difference D2. The difference D2 can be different from the difference D1 according to the migration of the occlusal plane. In an embodiment, the difference D2 is slightly smaller than the difference D1, for example, the difference D2 is at least 10% smaller than the difference D1. The difference in the values ​​of the difference D1 and D2 can indicate that the accommodation areas 1124 and 1125 are relatively Fig.21 In particular, the starting occlusal plane 310, SKE and Fig.21 The angle W2a between the training sliding plane TGK shown can be smaller than the starting occlusal plane 310, SKE and Fig. 20 The angle W2b between the illustrated training sliding planes TGK is, for example, at least 10% smaller than the value of the angle W2b.

[0655] In other embodiments, angle W2b may be smaller than angle W2a. Angles W2a, W2b may vary the same on the right and left sides, or may vary differently on the right side of the tooth / tooth element compared to the left side.

[0656] If the lateral edge gap 1122 is not used (see e.g. Fig. 22 and Fig.23), and for example, therefore also without using an occlusal gap, the projections 1125 and 1135 can be omitted, since with the projection 1125 the material of the upper jaw device 11 would extend over the entire occlusal region up to the teeth / tooth elements, and with the projection 1135 the material of the lower jaw device would extend over the entire occlusal region up to the teeth / tooth elements. However, the arrangement of the receiving areas 1124, 1125 to the training sliding plane TGK can remain essentially unchanged.

[0657] Fig. 22 In the upper part, a section through the sliding surface of the device for shifting the occlusal plane is shown, and in the lower part, a plan view of the device for shifting the occlusal plane is shown. Fig. 22 A first smooth sliding surface 1123 is schematically shown, which can coincide as accurately as possible with a transverse plane of cranial orientation, which is parallel to the axes 1110 and 1115 . Fig. 22 Likewise shown is an occlusal plane 1111, for example, a starting occlusal plane 310, SKE, which is inclined relative to the direction of the transverse axis 1110 when viewed from the front. The starting occlusal plane can also be inclined relative to the first smooth sliding surface 1123 when viewed from the side in a sagittal section (not shown). Fig. 22 As shown in, see for example Fig.21 ). However, this is not required.

[0658] If the teeth are numbered 1 to 7, starting from the middle incisor, as is customary in dentistry, a clear asymmetry can be seen, in this case due to the missing 7th molar on the right side of the picture. The support points 1125 can still be positioned according to the symmetry plane of the skull. The line between the support points 1125.1 of the right tooth 3 and the left tooth 3 is therefore not symmetrical to the dental arch, but corresponds to a differently positioned cranial symmetry. Similarly, the posterior right-left line between the left tooth 3 and the support points 1125.2 of the left tooth 3 can also not be symmetrical to the dental arch, but to the skull, see for example the line or plane 1205.

[0659] The symmetry of the skull can particularly define the starting point of the muscles and is crucial for neuromuscular function. From the perspective of mechanical contact points and force transmission, it can be seen that in the cross-sectional view AB, the edge gap 1122 width is preferably 0.4 mm. If the optional edge gap 1122 is used, the edge gap can avoid the lateral force being directly transmitted to the teeth 1221. Due to the partially arcuate shape of the edge gap 1122 and the free space 1124 reserved for the teeth, the device 10 cannot be a tightly mounted splint, but a loosely mounted device. In this embodiment, the device can only be placed on the support areas 1125.1 and 1125.2.

[0660] If the edge gap 1122 is omitted instead and the splint 1120 is in direct contact with the teeth, the teeth will be subjected to lateral forces and the resulting forces on the teeth will no longer be perpendicular to the separation sliding plane. This will reduce the training effect, but this is not necessarily the case, for example, if the sliding surface 1123 exists and there is a corresponding counter-sliding contact area, such as a similarly planar sliding surface or other element, such as a raised portion of the tooth / tooth element or a mandibular device protrusion of the relevant device (such as 10.1, 10.4, etc.).

[0661] As mentioned several times above, even without using the orthosis function 275 , an occlusal plane can be learned, wherein a sliding surface, in particular a flat sliding surface, is optional, ie in particular also including the above-mentioned edge gap 1122 .

[0662] The theoretical connection of the relearning process will be shown below using the orthosis function 275 as an example, although this is not intended to limit the scope of protection, but to help understand the device. Since the occlusal surface of the tooth 1221 also forms a lateral mesh with the splint 1120, the occlusal surface of the tooth cannot be shaped, and the edge gap 1122 can extend to the support area 1125, which preferably does not transmit lateral forces, but only pressure. From a neurophysiological point of view, the low-friction lateral sliding surface 1123 has the effect that the force can only act vertically on the sliding surface as long as the sliding surfaces of the maxillary and mandibular parts do not collide. This vertically acting pressure can be sensed by the retaining fibers of the teeth (Sharp's fibers) and fed back to the sensors of the bite device. At the same time, the muscle spindles and / or ligament spindles can also sense the load and stretch of the muscles, ligaments and / or tendons. This can change the control of the muscles by the sensory motor area of ​​the brain, which can also be called relearning. For this biomechanical and neurophysiological training function, it is important that the separation sliding plane is not on the current occlusal plane 111, but on the cranial transverse planes 1110, 1115. Since the separation sliding plane 1123 is inclined relative to the starting occlusal plane 1111, some teeth of the maxilla often penetrate the mandibular part, which can then be manipulated accordingly.

[0663] A similar relationship applies if marginal clearance is not used. In this case, relearning of the occlusal plane may occur during feeding, or during separate training sessions, or through involuntary occlusal movements while the device is worn.

[0664] For teeth extending across the separation sliding plane 1100, for example, there may be larger recesses in the opposing device components to still allow sliding motion without edge gaps or without multiple edge gaps.

[0665] The edge gap 1122 between the edge of the planar recess 1124, 1134 and the tooth / tooth element can preferably be greater than 0.3 mm, particularly preferably between 0.4 mm and 1.4 mm. As long as there is a penetration recess 1122 or 1132, i.e., when the tooth or tooth element of the mandibular UK, 4 extends into the maxillary device 11 and / or when the tooth or tooth element of the maxillary OK, 5 extends into the mandibular device 11, the freedom of movement of the mandibular relative to the maxilla along the separation sliding plane 1110 is limited by the edge gap 1122 of the planar recess 1124, 1134 or the receiving area 1124, 1134. The biomechanical and neurophysiological effects of the device 100 used as a training device can be unaffected by the restricted lateral range of movement, because in the equilibrium position there is still lateral flexibility, which flexibility is still maintained by the edge gap 122. As mentioned above, other measures can also be taken instead of just a small edge gap.

[0666] The biomechanical function of the orthotic device with a training effect can be achieved after the maxillary module / device 1120 is placed on the mandibular module / device 1130 and the two modules are brought into contact with the dental arches of the maxilla 1221 and the mandible 1231 in the mouth as a set by closing the mouth. At this point, the mandibular UK, 5, 1230 and the maxillary OK, 4, 1220 can be placed in relative positions defined by the personalized 3D geometry of the modules. At the same time, right-left and back-to-front sliding movements and torsion around the axis 1160 perpendicular to the separation sliding plane can be performed freely within a certain range and may be almost frictionless. As a result, the orthogonal condition effect of the contact forces between the maxillary OK, 5, 1220 and the mandibular UK, 4, 1230 can begin.

[0667] This balance may be relatively unstable or metastable biomechanically, since the retaining components of the teeth can be eliminated by the sliding surface 1110. It is this unstable or metastable force state that can be manifested in detail as a mechanical instability with the lateral sliding of the mandibular UK, 5, 1230 forward or backward, left or right, which needs to be or can be stabilized by the neuromuscular system like upright walking. Therefore, the sense of balance can be activated, which can train the neurophysiological and sensory motor structures of the jaw joint and the bite device, and even act on the muscles of the head and neck. A similar process can also occur if the edge gap 1122 is not used.

[0668] Fig.23The tooth support area of ​​the maxillary OK, 5, 1221 in the device for shifting the occlusal plane (see maxillary device 1120) is shown in detail. FIG. 32 shows a detail of the support area 1125 in a particularly preferred embodiment. The position of the support area can be aligned with the cranial symmetry of the patient's skull, for example, a DVT recording of the head at the position of the support area is taken. The support area 1125 minimizes lateral densification. In addition, an edge gap 1122 can be present. The support area 1125 does not necessarily have to be circular and can be designed so that lateral forces are exerted as little as possible. A preferred embodiment is a projection supported on a very small area, and the edge gap 1122 can be provided around it. Thus, the support 1125 can transmit forces perpendicular to the separation sliding plane TGE, but the support does not, for example, clamp the teeth laterally. The pressure generated by the occlusal pressure can only be transmitted point by point in a relatively small area 1125. The diameter of the preferred support area 1125 is less than 4 mm, particularly preferably less than 2.5 mm, and the edge gap is preferably less than 1 mm, particularly preferably less than 0.5 mm.

[0669] Fig.24 Schematically shown are a first device 10.1 for shifting the occlusal plane and a second device 10.2 for shifting the occlusal plane. As mentioned above, these devices can be placed in a predetermined order in the first position and the second position, but this is not necessary, as long as, for example, the second device is placed in sequence after the first device.

[0670] Instead of a flat sliding surface GF, other sliding contact areas can also be used, for example a pairing of a flat sliding surface with other counter-sliding elements or uneven surfaces. The flat sliding surface can be arranged in the upper jaw device 11.1 or the lower jaw device 12.1. However, it is also possible to alternate within a device or between different devices 10.1, 10.2, etc., for example a flat sliding surface on the upper right and a flat sliding surface on the lower left.

[0671] The device 10.1 comprises an upper jaw device 11.1 and a lower jaw device 12.1, wherein:

[0672] - a flat first sliding surface region GF1.1 and a flat second sliding surface region GF2.1 are located on the underside of the maxillary appliance 11.2,

[0673] a flat third sliding surface region GF3.1 and a flat fourth sliding surface region GF4.1 are located on the upper side of the mandibular device 12.1, and

[0674] In the use state of at least one device 10 . 1 , the first sliding surface region GF1 . 1 and the fourth sliding surface region GF4 . 1 as well as the second sliding surface region GF2 . 1 and the third sliding surface region GF3 . 1 slide relative to one another in the plane GE1 .

[0675] The device 10.2 comprises an upper jaw device 11.2 and a lower jaw device 12.2, wherein:

[0676] a flat first sliding surface region GF1.2 and a flat second sliding surface region GF2.2 are located on the underside of the maxillary appliance 11.2,

[0677] a flat third sliding surface region GF3.2 and a flat fourth sliding surface region GF4.2 are located on the upper side of the mandibular device 12.2, and

[0678] - In the use state of at least one device 10.2, the first sliding surface area GF1.2 and the fourth sliding surface area GF4.2 as well as the second sliding surface area GF2.2 and the third sliding surface area GF3.2 slide relative to each other in a sliding plane GE2, which can differ from the sliding plane GE1, for example in terms of the inclination angle or other parameters mentioned above.

[0679] In other embodiments, non-planar contact areas are used instead of planar sliding surfaces. However, the geometrical relationships mentioned still apply to these contact areas, wherein reference can be made to the plane corresponding to the sliding plane GE with regard to the distances.

[0680] Fig.25 The arrangement of the recessed areas of the teeth relative to the sliding plane is shown in the right part of the maxillary appliance 11.1 of the first device 10.1 and in the right part of the maxillary appliance 11.2 of the second device 10.2.

[0681] In the upper jaw device 11.1 of the first device 10.1, the following situations may occur:

[0682] the first right receiving area AB1a.1 of the first right tooth Z.1a.1 has a first right distance A1a.1 to the deepest point of the plane / sliding plane GE1 or the sliding surface GF1.1,

[0683] the second right receiving area AB1b.1 of the second right tooth Z.1b.1 has a second right distance A1b.1 to the deepest point of the plane / sliding plane GE1 or the sliding surface GF1.1,

[0684] The first difference D25a is obtained by subtracting the value of the first right distance A1a.1 from the value of the second right distance A1b.1.

[0685] In the maxillary devices 11.2, 12.2 of the second device 10.2, the following situations may occur:

[0686] the first right receiving area AB1.2 of the first right tooth Z.1a.2 has a first right distance A1a.2 to the plane / sliding plane GE2 or to the deepest point of the sliding surface GF1.2,

[0687] the second right receiving area AB1.2 of the second right tooth Z.1b.2 has a second right distance A1b.2 to the plane / sliding plane GE2 or to the deepest point of the sliding surface GF1.2,

[0688] The second difference D25b is obtained by subtracting the value of the first right distance A1a.2 from the value of the second right distance A1b.2.

[0689] The value of the first difference D25a may differ from the value of the second difference D25b, for example, due to a migration of the occlusal plane, in particular a change in the inclination of the occlusal plane, for example in a sagittal section or a parasagittal section, in particular of at least 0.3 mm or at least 0.5 mm, and / or in a value in the range of 0.3 mm to 2 mm.

[0690] The same also applies to the left side, ie, independently of the right side. In another embodiment, the mentioned relationship can apply to the right side of the device 10.1, 10.2, and can also apply to the left side of the device 10.1, 10.2.

[0691] although Fig.25 Only the upper jaw devices 11.1 and 11.2 are shown, but the above-described relationships also apply to the lower jaw devices 12.1, 12.2 independently of or in combination with these devices.

[0692] The above relationship also applies if other sliding areas or "densified" areas that cannot slide against each other are used instead of the planar sliding surfaces GF1.1, GF1.2.

[0693] In other embodiments, non-planar contact areas are used instead of flat sliding surfaces. However, the geometrical relationships mentioned still apply to these contact areas, wherein reference can be made to the plane corresponding to the sliding plane GE or the sliding surface or surfaces GF1.1, GF1.2 with regard to the distances.

[0694] Fig.26 shows the arrangement of the recessed areas of the teeth relative to the sliding plane in the upper jaw device 11.1 of the first device 10.1 and the upper jaw device 11.2 of the second device 10.2,

[0695] In the upper jaw device 11.1 of the first device 10.1, the following situations may occur:

[0696] the right-hand receiving area AB1.1 of the right tooth Z.1a.1 has a right-hand distance A1a.1 to the deepest point of the plane / sliding plane GE1 or sliding surface GF1.1,

[0697] the left receiving area AB2.1 of the left tooth Z.2a.1 has a left distance A3a.1 to the deepest point of the plane / sliding plane GE1 or sliding surface GF2.1,

[0698] Wherein the first front difference D26a is obtained by subtracting the value of the right distance A1a.1 from the value of the left distance A3a.1, and

[0699] In at least one maxillary device 11.2 of the second device 10.2, the following may be true:

[0700] the right-hand accommodation area AB1.2 of the right tooth Z.1a.2 has a right-hand distance A1a.2 to the deepest point of the plane / sliding plane GE2 or sliding surface GF1.2,

[0701] the left receiving area AB2.2 of the left tooth Z.2a.2 has a left distance A3a.2 to the deepest point of the plane / sliding plane GE2 or sliding surface GF2.2,

[0702] The second front difference D26b is obtained by subtracting the value of the right distance A1a.2 from the value of the left distance A3a.2.

[0703] The value of the first front difference D26a may differ from the value of the second front difference D26b, in particular by at least 0.3 mm, or at least 0.5 mm and / or by a value in the range of 0.3 mm to 2 mm. This may be due to a migration of the occlusal plane, for example a change in the inclination of the occlusal plane and / or a change in another position parameter or parameters, in particular in the frontal section or parafrontal section.

[0704] The above relationships also apply to the mandibular devices 12.1 and 12.2, for example, independently of the conditions in the maxillary devices, or in combination therewith.

[0705] The above relationship also applies if other sliding areas or "densified" areas that cannot slide on each other are used instead of the planar sliding surfaces GF1.1, GF1.2, GF1.1, GF1.2.

[0706] in particular, Fig.25 and Fig.26 The embodiments in the drawings may be used in combination, or other embodiments described in the above illustrated embodiments may be adopted.

[0707] In other embodiments, non-planar contact areas are used instead of flat sliding surfaces. However, the geometrical position relationships mentioned still apply to these contact areas, wherein reference can be made to the plane corresponding to the sliding plane GE or one or more sliding surfaces GF1.1, GF2.1, GF1.1, GF1.2 with regard to the distance.

[0708] FIG27 shows the height components of the mandibular device and their corresponding final treatment 300. FIG27 shows the height components of the mandibular device and their corresponding final treatment 300. Fig.27a The upper part shows a schematic diagram of a very simplified partial view of the device 11, wherein the device 11 covers Fig.27a and 27b A half-arch is shown, in this case with seven teeth 1 to 7. In the molar region 5, 6, 7, the device can be extended in the chewing thickness by means of onlay-like elements (one or more height elements), so that the contact surface of the device 11 relative to the opposite side (not drawn) is significantly higher than the natural chewing surfaces of the cross-hatched teeth 1 to 7. The individualized occlusal plane of the complete set of patient P is cut in the mandible through the line 601 in the image plane.

[0709] A preferred calculation method uses the minimization of the sum of squares of the occlusal plane distances. The new individualized occlusal plane 602 generated by the device 11 is located closer to the opposite side (not shown), i.e., higher in FIG. 27 . The two intersection lines of the occlusal planes 601 and 602 with the drawing plane are not parallel. The new occlusal plane is therefore higher and is inclined, i.e., in particular in the sagittal plane. In addition, there may be a migration of the premolars, molars and incisors within the occlusal plane (not shown).

[0710] In the frontal section, the inclination of the occlusal plane can remain unchanged, for example, when the set of teeth already has symmetry in the teeth. As an alternative or in addition, the occlusal plane can also be shifted in the frontal section, ie in particular a change in inclination, in which case a height element can also be used.

[0711] Figure 27b The final treatment 300 is schematically shown in FIG. The medical elements 111.1 to 11.7 are placed separately on the teeth 1 to 7. The original continuous device 11 can be replaced by 7 independent medical elements 111.1 to 111.7. The occlusal plane generated by the medical element 111 is shown in this schematic diagram. Figure 27b Zhongyu Fig.27a The same as in the case of the occlusal contours, as they are essentially the same. As long as the crown and its root are relocated after the final treatment 300, the effective occlusal plane may change accordingly, but it will still be higher than before.

[0712] The key point is the question of why it is so important to re-elevate an occlusal plane that has already been displaced in life. In the first period of application of the set of devices 11, 12, it is necessary to quickly elevate the contact plane in order to create free space to migrate teeth 1 to 7. After the tooth migration, the contact plane can be slightly lowered. Due to the previous strong lifting, the ligaments and muscles of the jaw joint have been stretched, and now the jaw joint will obtain a beneficial relaxation in the new occlusal plane position. The difference in the position of the occlusal plane is exaggerated in Figure 27. In addition, the new occlusal plane 602 generally converges more compactly than the rear end of the old occlusal plane 601, that is, the opposite of the situation shown in Figure 27.

[0713] With regard to the jaw joint, the position of the new occlusal plane can cause the rear part of the mandibular UK4 to be lowered, thereby relaxing the jaw joint. In many cases, the rear part of the mandibular UK4 is lowered by much less than 2 mm, while the front part can reach 8 mm. Accordingly, the medical body 111 for the front teeth can be designed to be significantly longer than the old front teeth axis. It is not feasible to lift the front teeth out of the jaw. Therefore, the front teeth, canines and premolars can usually obtain correspondingly designed covers, inlays or veneers and table top forms, or corresponding full crown restorations can be performed.

[0714] Dataset

[0715] The present invention can be based on digital technology, ultimately capable of processing 3D surface and 3D volume data sets. The 3D data set can be obtained through a three-dimensional surface, which is preferably recorded using an intraoral scanner and / or DVT. The 3D data can be used to define a beneficial effective occlusal plane 602, which includes the cranial region, in particular the inner ear. The inner ear can define a biomechanically important transverse axis in the right-left direction.

[0716] In a preferred implementation, 3D data can be generated by a digital imaging method of the skull region and the jaw region, and a transverse axis parallel to the transverse axis of the inner ear region is defined. The favorable position of the occlusal surface can be defined as follows: the position is parallel to the plane of the transverse axis passing through the inner ear region in the transverse direction. The initial virtual occlusal plane defined in this way can also be referred to as the target denture / dentition plane TDP. The virtual target denture / dentition plane can realize the occlusal plane of the device 11, 12, and the contact surface of the tooth element of the device is aligned along the target denture / dentition plane when the device is installed on a real full set of teeth by designing the device. The position of the target denture / dentition plane can be obtained by using a patent applied by Frank Hornung in 2016 ("CranioPlan", which may be a registered trademark) and disclosed by EP 3 332 731 A1, and the document is cited in its entirety for all legal purposes. Therefore, in a particularly preferred embodiment of the method, the TDP can be aligned to the inner ear region along the transverse axis, and can be aligned according to other features of the skull or skull 1, 1200.

[0717] By means of the digital three-dimensional design of the surface, milling data or printing data can be generated. A suitable device can generate or produce an actual tangible kit or a first quantity 1…x of the device based on a digital image of the kit of the device. The first device can be adapted to the full set of teeth in a very personalized way and can already produce different types of changes, such as migration and veneers. Subsequent devices can be based on the tooth arrangement generated by the previous device and further influence and change it. In this way, a changed state can be produced in the patient's dental arch. The currently effective occlusal plane cannot be generated by the patient's dental arch, but by the device located on the dental arch. The set occlusal plane sequence can be achieved by appropriate 3D design of subsequent or sequentially arranged devices 11, 12.

[0718] In other words, the device 10, in particular the maxillary device 11 and / or the mandibular device 12, is proposed for the maxillary or mandibular, and consists of device elements (e.g. replicas of teeth) that can be combined into a device that covers the patient's dental arch Z1 (tooth element structure arranged in an arc) and / or dental arch Z2 (tooth element structure arranged in an arc). A kit 100 of devices 10 is provided, each of which can be individually adapted to a single dental arch Z1, Z2 in terms of aesthetics, biomechanics and dental technology. Alternatively, the device 10 can also only contain the maxillary device 11 and / or the mandibular device 12, for example in a part of the kit 100, or in the entire kit 100. Alternating maxillary devices 11 and / or mandibular devices 12 are also possible in the device 10.

[0719] The biomechanical adaptation, in particular to individual treatment requirements, may relate to the position of the occlusal plane. The occlusal plane is a plane that the set of teeth fits into in the usual sliding occlusal state. When the device 10 (maxillary device 11 and / or mandibular device 12) is placed in the mouth of the patient P, the device may come into contact with the opposite side (OK, 5 or maxillary device 11 or UK, 4 or mandibular device 12), wherein the contact surface is a tooth body / tooth element of the set of teeth or a tooth replica of the opposite second device (12 or 11).

[0720] Each tooth replica of one or more devices 10 (maxillary device 11 and / or mandibular device 12) can be utilized by a centrally supported (at least one free end) or end-supported (fixed at the ends) dental bridge element, or by a receiving area of ​​a dental element. The dental elements in the dental arch of the full set of teeth can be correspondingly accommodated by the receiving elements of the device 10, such as the maxillary device 11 and / or the mandibular device 12.

[0721] By placing the receiving elements of the device 10 (maxillary device 11 and / or mandibular device 12) in the device 10 (maxillary device 11 and / or mandibular device 12) differently from the tooth elements in the complete set of teeth, reaction forces and reaction moments can be transmitted from the device 10 to the tooth elements. These forces and moments on the tooth elements can cause the tooth elements in the complete set of teeth to migrate in the dental arch. The tooth elements / tooth elements are preferably selected from: natural teeth, filled teeth, crowned teeth, veneer teeth, pile teeth, implants, molars, etc.

[0722] Therapeutic, aesthetic and restorative treatments in dentistry aim to maintain or achieve the healthiest possible state of teeth, jaws, joints and muscles as well as nerves. Therefore, the spatial position and orientation or inclination of the occlusal plane relative to the maxilla and to the mandible may play an important role that is not as easily perceived as the visible aesthetics of a complete set of teeth. However, the position of the biomechanically and neurophysiologically effective occlusal plane also has an important influence on the health of the neck, the occlusal muscles, the neck muscles, the shoulder and arm regions, and even the spine. Changes in the biomechanically and neurophysiologically effective occlusal plane are often evident by rapid changes in muscle tone, improvements in headaches and back pain. In the long term, shifts in the occlusal plane lead to therapeutically desired changes in the muscular and skeletal structures of the skull and head region, shoulders, back, etc. The biomechanical and neurophysiological effects of the occlusal plane may depend on the relative positioning of the occlusal surfaces that actually come into contact.

[0723] Thus, the proposed kit 100 allows a biomechanically and physiologically valid occlusal plane to be adjusted independently of the existing anatomical and dentally configured occlusal plane.

[0724] The kit 100 is capable of utilizing the individually designed 3D geometry of the device 10 (11, 12) to directly integrate with the existing dental element structure (dental arch) in the jaw of the patient (P) to establish an individualized biomechanically and neurophysiologically effective occlusal plane.

[0725] As the position of the teeth in the jaw gradually changes, a defined occlusal plane may also be gradually set for the set 100 of devices 10 ( 11 , 12 ), for example by correspondingly designing the 3D geometry of one or more devices 10 ( 11 , 12 ).

[0726] If the position of the teeth in the jaws does not change or hardly changes, a defined occlusal plane can also be set step by step for the set 100 of devices 11 , 12 , for example by means of a correspondingly designed 3D geometry of the devices 11 , 12 .

[0727] In order to define the occlusal plane in relation to the head and jaws of the patient P, it may be necessary to directly combine the tooth arrangement and the 3D geometry of the devices 11, 12. The devices, if installed in an incompatible set of teeth, may not only lead to jamming of the tooth receiving areas, but may also lead to incorrect adaptation of the occlusal plane.

[0728] For the individual definition of an effective occlusal plane that is biomechanically and neurophysiologically advantageous, it may be necessary to know the relative position of the occlusal plane to the skull (cranial) structures. The relative position of the inner ear and the cochlea, especially the right and left positions, is far more important than the outer ear region. Alternatively or additionally, the position of the eyes is also very important, because the jaw, neck and shoulder girdle work together to stabilize head movements, thus making it possible to achieve clear vision during movement, for example, with the help of biosensor mechanisms.

[0729] Therefore, a primary goal of providing truly efficient and personalized orthodontic or dental care to patient P may be to define an occlusal plane that is highly effective for patient P, and to perform dental care to at least approximate achieving that occlusal plane.

[0730] However, the acceptance of splints or dental and / or orthodontic medical systems may be very dependent on their aesthetic appearance, fit feel in the mouth, and effect on speech.

[0731] A second goal is to provide medical treatment that is highly acceptable to the patient population, so these devices should be aesthetically and / or functionally attractive compared to braces or orthoses, which otherwise would not function and / or could not be worn sufficiently permanently.

[0732] The second object can be achieved by using at least one quarter or at least half of the device 10 (11, 12) in the kit 100 in a particularly preferred embodiment, so that at least one veneer element or at least two veneer elements are provided in the anterior tooth area (1, 2, 3, 4).

[0733] If these veneer elements are used and the underlying covered tooth / tooth element needs to be relocated, this can be achieved by relocating the receiving area of ​​the covered tooth element in the device 11, 12 relative to the device 11, 12. This will produce reaction forces and reaction moments on the tooth and its root, even if the visible and aesthetic veneer elements are not significantly moved. Thus, a new personalized occlusal plane can be set by one step or a few steps, preferably few steps. At the same time, aesthetically advantageous veneer elements can be installed in the anterior and / or canine area, which are implemented as part of the device 10 (11, 12) with suitable dimensions and suitable relative positions. In addition, targeted tooth / tooth element migration can be performed as needed, covered by the veneer elements or visible by the partially synchronously moved tooth elements, so as to move the tooth / tooth element to a suitable position and spatial orientation in the jaw of the patient P.

[0734] After therapeutically and aesthetically advantageous use, the device 10 (11, 12) can be removed. The tooth / tooth element in the dental arch Z1, Z2 of the patient P can now be arranged in a different way than before. The goal is to make the tooth / tooth element better suited for the final treatment 300. If the teeth are poorly aligned due to wear, defects or poor morphology, simple migration may not be sufficient to achieve the alignment goals, because the occlusal plane may not be correct. In addition, the aesthetics and geometry of the teeth may be affected by wear, causing the teeth to become too short, for example due to intense bruxism. The final treatment 300 of the teeth / tooth elements can then be performed after the tooth / tooth element has been repositioned.

[0735] Where a tooth / tooth element is missing in the dental arch of the individual, a bridge element can be designed, or an implant can be prepared and placed. The geometry of the artificial crown / tooth element as an implant superstructure can be positioned with reference to a dental replica of a previously aesthetically and / or biomechanically effective device shaped with which the patient P is already familiar.

[0736] The device 10 (11, 12) can gradually take on the appearance of the final dental medical body 300 during the step-by-step treatment of the complete set of teeth. Nevertheless, due to the covering function, the tooth elements of the device can be larger than the tooth body / tooth elements of the final medical body in at least one dimension. On worn or modified teeth, the shape of the tooth replica / veneer element in the device may already take on the form of a crown, or preferably be slightly larger in at least one dimension. Usually this enlargement occurs on the lingual-buccal and lingual-front sides, because otherwise it would be impossible to cover and guide the tooth body.

[0737] As a temporary measure, a personalized splint having a three-dimensional geometric structure that is almost identical to the last device 10 (11, 12) in the kit can be arranged and temporarily glued to the prepared dental arch as the final medical body. During this process, and before, a material that is very high-quality in terms of aesthetics and mechanical properties can be used as material. Aesthetically and / or mechanically very high-quality is multi-layer PMMA (polymethyl methacrylate, plexiglass), which can also have a color gradient so that the tooth replica at the back is darker than the tooth replica at the front. Thus, a plurality of layers can form the preform, for example, the number of layers is in the range of 10 to 30 layers, or in the range of 10 to 20 layers. The technical effect of the multi-layer structure can be to imitate the color and / or function of natural tooth material as accurately as possible.

[0738] Not only a biomechanically and / or neurophysiologically effective occlusal plane setting may be of personal importance. It is also important for the subsequent final medical device 300 to transfer as much tooth material as possible from the patient's complete set of teeth to the calculated target. For this purpose, a transfer element can be used. The simplest transfer element can be a receiving element for the tooth material / tooth element, which is designed so that it exerts physical forces and moments on the teeth as long as the device is placed on the dental arch.

[0739] Further migration elements may be recesses in combination with attachments bonded to the teeth, sliding elements, splint elements, specially designed contact surfaces on opposite sides, preferably solid built ramp elements etc.

[0740] The tooth element can be covered and moved by the device 10 (11, 12). The tooth element can also be an implant. Implants should only be subjected to compressive loads based on biomechanics and should not be subjected to tilting or tilting migration. Because the implant is bone-grown, rather than fixed in the bone around the natural tooth root by Sharp's retaining fibers. Bone-grown implants may behave differently than tooth roots located in the jawbone, because there can be no retaining Sharp's fibers on the implant.

[0741] A particular type of migration can be the migration of teeth relative to the jaw bone, mainly in the direction of the tooth axis. Teeth with natural roots respond to the missing loads through the function of Sharp's fibers, so that the tooth grows out of the jaw bone by a few tenths of a millimeter - even in elderly people. Implants cannot or should not migrate significantly from their established position.

[0742] The device 10 (11, 12) can include a marginal clearance element 1122, which can be individually adapted to surround the recorded tooth / tooth component, forming a marginal clearance and an occlusal clearance so that the tooth is free of stress. The free tooth can thus be slightly displaced axially out of the jawbone at this point. This is usually not sufficient to establish a height of an occlusal plane that works well from a biomechanical and neurophysiological point of view. Therefore, the displacement of the defect is usually compensated by placing an onlay-like structure (height element) as part of the device 10 (11, 12) on the so-called underlength or shortened tooth, so that the distance between the corresponding occlusal plane and the tooth / tooth component placed behind is maintained.

[0743] At the latest when the complete set of teeth contains implants, the limit of migration of these implant / tooth elements is reached by the aligner, compared to the device 1 (11, 12) in the 100 sets proposed here, because height elements can still be used, which are larger compared to other areas of the device and / or compared to the low height of the deep-punched film.

[0744] Nevertheless, a shift of the occlusal plane is still possible, for example, because it may be better from a neurophysiological, biomechanical and functional point of view, but this will lead to collisions between all teeth, and the teeth in the root direction, that is, upward or downward, or possibly in other directions, are usually not able to be shifted accordingly to the desired extent. In this regard, the device 10 (11, 12) of the kit 100 uses a height element to achieve the shift of the occlusal plane, especially when the inclination of the occlusal plane changes, and the height element can cover and / or support the implant.

[0745] So far, in most cases, the orthodontic transfer that can be achieved is a transverse translation movement and a superimposed tilting (rotation about the transverse axis) and / or rotation about the long axis of the tooth or the axis perpendicular to the occlusal plane. Such a transfer can in principle be described by six parameters, and three translation directions can be defined for each tooth, even if the transfer can be zero. It is also possible to define three rotation directions, when a tooth needs to be tilted or tilted about the long axis.

[0746] Traditional methods usually use brackets and wires, or use the aligner method. The aligner method works by tilting and shifting the teeth, specifically to create a more aesthetically pleasing picture side by side. For example, a name like "Dr. Smile" represents a more beautiful smile.

[0747] Traditionally, sets of aligners are manufactured by deep drawing as a step-by-step effective migration device and have a wall thickness resulting from the deep drawing process. If ramps or side structures are added to the aligner, these local modifications to the preferably transparent aligner will be hollow due to deep drawing. Due to the low mechanical stability, especially if a supporting structure is missing, it is impossible to keep such a device in the mouth while eating, thus omitting a significant training effect.

[0748] Therefore, until now, it has only been possible to perform tooth displacements that do not significantly affect the position of the occlusal plane, in particular not in a few steps or in rapid transitions. In particular, it has not been possible to change the inclination of the occlusal plane until now. But now there is a new possibility to shift the occlusal plane using splints like aligners and / or splints that have an aesthetic effect or encourage wearing, without having to correspondingly significantly shift the teeth in the event of such a change in the occlusal plane.

[0749] The kit 100 presented here describes a technique for how to rapidly achieve therapeutically targeted displacement of the occlusal plane by technical means, even if the teeth are unable to keep up with the rate of such displacement. Treatment can continue, wherein one or more devices (10, 12) can be gradually changed so that the tooth is received in the dental arch and displaced as much as possible, preferably on at least one tooth / tooth element or more teeth / tooth elements.

[0750] The device 10 (11, 12) may have a receiving area for each tooth body / tooth element of the dental arch Z1 and / or dental arch Z2. These receiving areas may allow the device (11, 12) to be placed on the dental arch Z1 and / or Z2. The device (11, 12) may generate a retaining force by adapting the design of the tooth body / tooth element, and the individual tooth elements may be more or less movable by reaction forces and reaction moments.

[0751] The setting of the new occlusal plane can be determined by an onlay element arranged occlusally adjacent (placed above the tooth element in the mandible) or at least one height element which is designed such that its contact surface with the opposite side is closer to the opposite side than the contact surface of the occlusal surface of the covered tooth element.

[0752] Therefore, deep-drawn aligners with additional functions can be used to change the joint position. A change in the position of the jaw joint or the joint head on the mandible may be a stimulus for the growth of the jaw bone, but this process is very slow. The migration of the jaw joint cannot directly change the position of the occlusal surface of the tooth element in conventional aligners, thereby generating a new position of the occlusal plane.

[0753] However, the splint / splint kit proposed by kit 100 can quickly achieve this: the splint / splint kit can change the position of the occlusal plane by changing the thickness of the onlay-like construction on the occlusal surface, and then the movement of the teeth will occur, for example as far as possible. In elderly patients, the construction may need to reach 5mm. However, regardless of the age of the person P, the teeth can only move 1mm from the bone with their roots at most, and for a 50-year-old person it may be less, for example only 0.5mm at most. A tilting or tilting migration may be easier to achieve, which may result in a lateral migration of the teeth of up to several millimeters, thereby helping to adjust the dental arch of the mandible, such as moving it forward or backward.

[0754] However, for biomechanical reasons, the height of the relative occlusal surfaces in the mandible and maxilla can be decisive when correcting the physiological occlusal plane. In contact occlusion, the position of the mandible relative to the maxilla can be caused by the adjacent row of onlay-like occlusal structures (height elements). Thus, the onlay-like occlusal structures (height elements) can be integrated only into the maxillary appliance 11, only into the mandibular appliance 12, or into both appliances 11, 12.

[0755] For example, if the patient's teeth are worn due to bruxism, etc., this wear is usually unilateral and asymmetrical. In this case, the jaw joint can first be relaxed and the ligaments can be pre-stretched. And this can be achieved by rapid changes (e.g. a few mm per week) - which can be faster than the gradual lifting of the teeth of the mandible or the usual alignment changes (e.g. less than 0.5 mm per week). Functional preparation of the longer teeth for the new bite position and the so-called re-juvenation can be achieved for each tooth element / tooth replica by thickening (height element) of the onlay type or adding a suitable occlusal surface shape and appropriate thickness, wherein the tooth element / tooth replica of the tooth splint-like device 10 (11, 12) preferably forms an integrally connected dental arch or a replica of a dental arch, which can be placed on the dental arch of the patient P. By means of a geometrically preferred occlusal design, a new occlusal position relative to the mandibular UK, 4 or the maxillary UK, 5 can be immediately produced when using at least one device 10 (11, 12). However, the occlusal structure does not necessarily have to be formed in an onlay-like manner (height element), but can also have other functional geometries, for example as a flat sliding surface, in particular on at least one height element, or as a rolling sliding surface, in particular on at least one height element. A plurality of adjacently placed tooth elements or tooth replicas or veneer elements of the device 10 (11, 12) can be combined to form a functional dental arch area.

[0756] The preferred sliding surface can be realized via 3 or 4 or more tooth elements or tooth replicas as part of the device 10 (11, 12). The sliding surface elements can be planar or can form other types of supersurfaces in space, such as cylindrical. It is crucial that molars are preferably used, and the molars are graded and inclined upward and / or downward by the device so that a new contact state is formed when they come into contact. It is pointed out again that the new contact state between the maxillary OK, 5 and the mandibular UK, 4, for example by splints placed in contact with each other, at least for example the maxillary device 11 and / or the mandibular device 12, is not produced directly by the migration of teeth, nor by a slope, but is produced, for example, by a thickening or height element of the device 10 (11, 12) of the type of an onlay in the occlusal surface area of ​​the tooth element.

[0757] Known transparent deep-drawn aligner splints cannot, without further modifications, be used to set new occlusal planes using onlay areas of different thickness (height elements) on tooth elements, unless these teeth have been relocated according to six preset parameters. Such modifications are only possible after understanding the contents of this document.

[0758] In a particularly preferred embodiment, the means 10 (11, 12) for shifting the occlusal plane, which are applied in sequence, are designed such that the occlusal engagement of adjacently placed tooth elements is designed to form a solid filled onlay-like region (height element) which can be up to 5 mm thick, for example. It is also possible to provide one or more cavities in the onlay-like region (height element), in particular when using a supporting structure, for example, according to a stable honeycomb or another arrangement of bars between the different cavities.

[0759] The area (height element) of the onlay-like design may preferably differ in the position and inclination of the contact surface of the opposite surface of the maxillary or mandibular device from the natural complete tooth embedded in the dental arch, for example in at least one spatial angle, and there may be an occlusal distance between the occlusal surface of the tooth element or tooth replica present as part of the device 10 (11, 12) and the occlusal surface of the tooth body / tooth element in the lower dental arch, i.e. the element directly anchored in the mandibular UK, 4 or the maxillary OK, 5 (e.g. in the bone and or connected to Sharp's fibers).

[0760] The thickness of the onlay-like structures (height elements) of the adjacently placed tooth replicas as part of the device 10 (11, 12) does not necessarily have to be successively decreasing or increasing, since the tooth in the lower arch may have been processed or at a different height in the arch. What is critical is only the new contact surface or occlusal plane formed after the use of the device and its biomechanical and physiological impact on the patient.

[0761] When facing the opposite side, the contact surface is preferably flat and smooth. This can facilitate the person's learning of the occlusal plane.

[0762] When the contact surface faces the opposite side, it can also be designed to be splint-shaped, spherical or spherical. This may ultimately affect the freedom of movement, stability and / or instability of the contact between the maxilla and mandible when the device 10 (11 and / or 12) is used.

[0763] The onlay-like thickness (height element) of the occlusal structure (height element) can be individually adjusted from one tooth element to another or from one tooth replica to another. This adjustment can be done in digital form by designing a second envelope surface outside the inner surface of the device 10 (11, 12) inclined or facing the tooth, in particular by using a Boolean function, the surface of the tooth or tooth element in the jaw can be subtracted from the digital data of the device 10 (11, 12). The 3D design freedom directed to the outer surface facing the opposite side allows a free design of the structure height (height element) while allowing the desired sliding properties, shape properties and / or kinematic movement properties of the contact surface that can be generated by contact with the opposite side.

[0764] Preferably, the design surface of the first part device 11 or 12 pointing to the opposite side and the corresponding design surface of the second part device 12 or 11 of the same device 10 are designed so as to form the desired relative position between the upper jaw and the lower jaw in the case of contact, as well as the possibility of movement or encryption according to the contact geometry of these design surfaces.

[0765] Therefore, when the patient uses the device 10 (11 and / or 12), the mandibular UK, 4 can quickly enter a new biomechanically and / or therapeutically required relative position relative to the maxillary OK, 5. In addition, a biomechanically and / or therapeutically required relative position can be achieved.

[0766] In a preferred embodiment, the onlay-like structural area is located in the area of ​​the molars (5), (6), (7), (8), for example in all four quadrants of the set. In contrast, in the canine area (3) and in the anterior area (1), (2), a veneer element is preferably designed as part of the device 10 (11, 12), also as part of the premolars.

[0767] If there is a bridge in the dental arch, an onlay-like structure (one or more height elements) as part of the device 11, 12 may at least partially span the bridge area.

[0768] If there are implants in the dental arch, it can be noted that the 3D contours and surfaces of the structural elements (height elements) of the onlay type do not exert any tilting moments on the implants.

[0769] A kit (100) is explained, the kit (100) having a device for supporting the migration of the occlusal plane of a person (P), comprising:

[0770] At least two device pairs 10,

[0771] The device pair 10 comprises a dental and maxillary device,

[0772] The dental and maxillary device comprises an upper jaw device (11) and / or a lower jaw device (12), and

[0773] wherein the device is designed to be worn by a person (P) in a predetermined sequence,

[0774] wherein, in at least one device 10.1, 10.2, at least one dental device (11, 12) comprises at least one height element on a first side,

[0775] wherein at least two contact areas are formed at different positions of the molar element at at least one height element,

[0776] wherein at least one further contact region is formed on a second side of at least one dental appliance 11, 12, and

[0777] Therein, at least three contact areas define a plane GE,

[0778] wherein the plane GE deviates from the initial occlusal plane of the person P or the current occlusal plane of the person P in the frontal section or the sagittal section by a degree of inclination of the change of at least one height element and / or by a degree of height position of the change of at least one height element,

[0779] In at least one other device of the kit 100 , in the frontal section or the sagittal section, different inclinations and / or different height positions of the respective planes are set by at least one other height element, which differs in the set height from at least one height element.

[0780] Furthermore, a method for designing a dental device is explained, in particular for designing or for designing and manufacturing a kit 100 according to the above-mentioned embodiments, improvements and examples, comprising the following steps:

[0781] recording the initial tooth arrangement of the teeth or tooth element structure of the person P in his upper jaw UK, 5 and / or the teeth or tooth element structure of the person P in his lower jaw UK, 4,

[0782] determining at least one reference structure of the person P before, during and after recording,
