Description

[0001] The present invention relates to a kit consisting of devices for gradually changing the position of a person's teeth, where the devices can each include at least two pairs of devices, and relates to a related design method, manufacturing method, and additional units. Background Art

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

[0003] - 1) readjusting the occlusal plane / occlusal surface, and / or

[0004] - 2) advantageously migrating the teeth in the entire set of teeth before, simultaneously, or afterwards, and / or

[0005] - 3) simultaneously improving the appearance and shape of the teeth aesthetically, where the aesthetic improvement often also brings about a functional improvement.

[0006] Dentistry includes, for example:

[0007] - the restoration of teeth,

[0008] - the use of implants,

[0009] - the aesthetic correction and improvement of teeth,

[0010] - the orthodontic (kieferorthopädisch) migration of the orientation and position of teeth in the upper and lower jaws.

[0011] Of particular importance is also the correction of the position and orientation of the occlusal plane / occlusal surface relative to the skull, as well as the correction of disorders in the jaw joints related to adverse conditions of the entire set of teeth. Detailed Description

[0012] The object of the present invention is to provide a kit consisting of devices for gradually changing the position of an individual's teeth, the kit including at least two pairs of devices. For example, the devices of the kit should be able to be easily manufactured or manufactured at low cost, and / or achieve a shorter treatment duration, and / or have a high wearer acceptance, and / or enable an overview of the treatment status at any time. In addition, a design method and a manufacturing method should be provided, which can be used, for example, to design and / or manufacture a kit consisting of devices, and alternatively or additionally can be used for other purposes. Related units should also be provided, such as computer systems, computer programs, computer program products, related digital design data, and related digital manufacturing data.

[0013] Regarding a kit consisting of devices, this object is achieved by the kit given in claim 1. The improvements are given in the dependent claims. Regarding the objects of the method and the unit, they are achieved by the patent subject matter according to the appended claims. The improvements are also given in the dependent claims.

[0014] A kit consisting of devices for gradually changing the position of a person's (e.g., a patient's) teeth may include at least two devices, which in themselves may each include at least one jaw device or at least two sub-devices, e.g., may each include a pair of devices. The jaw device may be implemented in one piece or in multiple pieces.

[0015] The jaw device may include device elements. The device elements may each include at least one receiving area for tooth elements (i.e., for teeth, denture elements, etc.). A veneer or veneer element may be a device element, which is preferably arranged at the anterior tooth position or the canine position. At the molar position (molar, premolar), there may be device elements having, for example, a height function or a ramp function.

[0016] According to an embodiment, the devices may each include at least one jaw device. At least one jaw device may be designed such that the receiving area of the jaw device can be placed on the dental arch of a person's upper jaw (i.e., may be an upper jaw device) or lower jaw (i.e., may be a lower jaw device).

[0017] According to an embodiment, the devices may be designed such that when the devices are worn in a predetermined order of the devices, the devices gradually change the tooth position through the mechanical interaction between the devices and at least one tooth element (i.e., for example, by the transmission of force and / or moment, especially torque). Each device or at least more than half of the devices may displace at least one tooth by a distance of, for example, 0.1 mm (millimeter) to 0.25 mm.

[0018] The tooth element may be a tooth, such as a natural tooth, such as a tooth crown or a partial tooth crown, or an artificial tooth whose root of the natural tooth has been replaced. The dental arch may be formed by an arc-shaped arrangement of tooth elements, such that it may also be referred to as a tooth element structure.

[0019] In the placed or use state, the upper jaw device may extend from a first tooth element in the molar position via a second tooth element at the canine position or the anterior tooth position to a third tooth element at another molar position on the other side of the dental arch compared to the molar position of the first tooth element. For each tooth element, there is a corresponding receiving area in the upper jaw device.

[0020] In the placed or use state, the mandibular device can extend from a first tooth element in the molar position via a second tooth element at the canine position or incisor position to a third tooth element at an additional molar position on the other side of the dental arch compared to the molar position of the first tooth element. For each tooth element, there is a corresponding receiving area in the mandibular device.

[0021] According to an embodiment, at least one jaw device of the first device can have, on its outer side, a first veneer element as a sub-region of the first device, in particular as a sub-region of the first jaw device.

[0022] According to an embodiment, at least one jaw device of the second device can have, on its outer side, a second veneer element as a sub-region of the second device, in particular as a sub-region of the second jaw device.

[0023] According to an embodiment, at least one optional jaw device of the third device can have, on its outer side, a third veneer element as a sub-region of the third device. The inclusion of the optional third jaw device can be used in particular to divide the "rocking movement" at the tooth element.

[0024] All three veneer elements can be located at the same position according to the tooth scheme. The veneer element can also be referred to as a dental veneer.

[0025] In a first cross-section, at the first veneer element, there can be a first outer contour and a first inner contour, in particular a front outer contour and a front inner contour.

[0026] In a second cross-section corresponding to the first cross-section, at the second veneer element, there can be a second outer contour and a second inner contour, in particular a front outer contour and a front inner contour.

[0027] Preferably, the following feature can also optionally be implemented: In a third cross-section corresponding to the first cross-section, at or in the third veneer element, there can be a third outer contour and a third inner contour, in particular a front outer contour and a front inner contour.

[0028] The relative position of the corresponding inner contour to the corresponding outer contour can change 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 an offset of the tooth element in the relevant receiving area, in particular an offset along at least one or more of the following directions:

[0029] - From front to back

[0030] - From back to front

[0031] - Axial torsion

[0032] - Laterally towards adjacent teeth, i.e., left or right,

[0033] - Also an offset from top to bottom or from bottom to top, if applicable.

[0034] The change in relative position or offset can be strictly monotonic, in particular increasing or decreasing strictly monotonically in one direction. Alternatively, a simple monotonic increase can also be achieved. Thus, in a series of devices following one another, there can also be devices with a constant relative position, for example because the offset is caused at other teeth.

[0035] Thus, in order, there can be no additional devices between the first device, the second device, and the third device. On the other hand, in order, there can also be additional devices between the first device and the second device and / or between the second device and the third device.

[0036] The numbering of the devices can be different from the numbering in the treatment plan, but this is not necessary. That is, the first device can be the first device according to the treatment plan. Alternatively, the first device can also be other devices according to the treatment plan, such as the second device, the third device, etc. According to the claims, the other numbering follows.

[0037] According to the claims, the first device can have a relative position A of the inner contour and the outer contour. According to the claims, the second device can have a relative position B of the inner contour and the outer contour. According to the claims, the third device can have a relative position C of the inner contour and the outer contour. Then, the following position order can be achieved: A, B, C or A, A, B, C, C or the like.

[0038] The cross-section can for example have a target occlusal plane as a reference, or a plane at a predetermined distance from the target occlusal plane.

[0039] The relative position of the first inner contour and the first outer contour can be different from the relative position of the second inner contour and the second outer contour.

[0040] 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 tooth can "move" relatively strongly, and the veneer (i.e., preferably its front side) can be stationary or move only relatively slowly.

[0041] The inner contour can include pressing elements (i.e., functional elements for tooth migration), in particular pressing elements that cause migration by means of at least one additional attachment at the tooth or tooth element or in the case of no attachment at the tooth or tooth element.

[0042] The change in the relative position of the inner contour and the outer contour can be shown in the change of the wall thickness contour. Thus, the wall thickness contour of the first veneering element (especially the front wall thickness contour) can be different from that of the second veneering element, and the wall thickness contour of the third veneering element (especially the front wall thickness contour) can be different from that of the second veneering element or from that of the first veneering element, especially due to the targeted change in the relative position of the corresponding inner contour and the corresponding outer contour, for example, different from the deep drawing process using a film with a uniform layer thickness, in which the inner contour and the outer contour coincide with each other, so that they have a substantially unchanged position relative to each other.

[0043] The technical effect of the change in the relative position of the inner contour and the outer contour is that there is a degree of freedom to determine the position of the outer contour independently of the position of the inner contour. For example, the outer contour can be realized or desired in the kit at an early stage, while the inner contour "imitates" the tooth element or realizes the migration of the tooth element.

[0044] The receiving area of the first veneering element can be designed to be different from that of the second veneering element and / or have a different position from that of the second veneering element. This difference can be suitable for causing the gradual migration of the tooth element. At the same time, the front wall thickness of the second veneering element can be different from that of the first veneering element, especially when the tooth element migrates from front to back or from back to front.

[0045] Therefore, when the tooth element migrates from back to front, the wall thickness, especially the front wall thickness, can generally decrease from the first veneering element to the second veneering element, and can also decrease from the second veneering element to the third veneering element if applicable. Here, the back wall thickness can, for example, increase correspondingly or remain unchanged.

[0046] Therefore, when the tooth element migrates from front to back, the wall thickness, especially the front wall thickness, can generally increase (along the entire course of the wall in the cross-section) from the first veneering element to the second veneering element, and can also increase from the second veneering element to the third veneering element if applicable. Here, the back wall thickness can, for example, decrease correspondingly or remain unchanged.

[0047] When the tooth element undergoes lateral migration, the front wall thickness can decrease in a sub-region and increase in another sub-region. However, the wall thickness to the adjacent tooth element can decrease or increase as a whole or along the entire course of the wall, especially when the adjacent tooth elements do not migrate simultaneously. This also applies to the torsion of the tooth or the lifting or combined migration of the tooth from the upper or lower jaw, such as torsion and lifting.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] The at least one first cladding element and the at least one second cladding element may be substantially identical in position and / or shape of their front outer contours.

[0052] For example, in the case of relatively small relevant tooth elements (such as teeth, tooth roots or implants, etc.), the front outer contour can be adapted to the tooth element located at the tooth position under the target tooth state or intermediate target tooth state (such as intermediate target tooth arrangement), as desired in the final medical body of the tooth element. The tooth element can be regarded as a residual occlusal element. 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 that completely corresponds to the target occlusal structure in the final medical body of the dentistry. Therefore, the migration of one or more tooth elements can be part of the treatment plan. Only a part of the tooth element can be migrated. Another part may already be in a suitable position, so that no migration is required with respect to this part.

[0053] "Fit" may mean to be consistent. Alternatively, "fit" may mean to be consistent with the target state as far as dental conditions allow.

[0054] The magnification 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)).

[0055] Isotropic magnification can be, for example, the so-called swelling in a too small canine or premolar; on the other hand, anisotropic magnification can be, for example, an increase in width.

[0056] Furthermore, compared to the relevant individual teeth and the relevant entire dental arch, the target tooth state can be more extensive. The dental arch in the device can be an anticipation of the target state of the dental arch in the upper jaw and / or the lower jaw, in particular an anticipation of the outer contour and / or the inner contour. It is generally desired to magnify the dental arch in the upper jaw or the lower jaw or both dental arches.

[0057] The anterior outer contour can present a magnification of the target tooth state in at least one dimension. According to another improvement, the anterior veneers of the first pair of devices and the anterior veneers of the second pair of devices can present the teeth at that tooth position in the target tooth state or in a magnification of the target tooth state. The magnification can be achieved, for example, by a value of 1% to 25%, preferably 5% to 15%, for example 10%. The magnification can be achieved using a factor (for example, a magnification factor of 1.01 to 1.25). The target tooth state or its magnification can include the shape, color, position, orientation, etc. of the relevant teeth (such as the relevant anterior teeth, canines, etc.). The veneers and / or the magnification can increase and / or ensure the stability of the device and are therefore a technical feature.

[0058] Therefore, in the design, the veneer can be a model or anticipation of the target state. On the other hand, as mentioned above, the veneer can also be designed according to other criteria.

[0059] The press-on veneer / veneer element can veneer the corresponding teeth in the state of being placed in a person's mouth. For example, the veneer can include recesses for the relevant teeth, especially recesses with or without an alignment function (i.e., depending on the treatment plan developed for the person). Alternatively, the veneer can also only partially surround the relevant teeth, for example, only be arranged on the front side of the teeth and not on the back side of the teeth.

[0060] It is also possible to use, for example, a press-on veneer / veneer element for which no teeth are assigned due to the absence of the corresponding teeth. In this case, the press-on veneer can assume a support function on the soft tissue or on or at the implant. These functions are described in detail below.

[0061] At least one dental veneer / veneer element can reproduce the physical outer contour or a slightly enlarged outer geometry of the outer contour of a tooth in a target state. As a result, a corresponding sensory impression can be generated, for example, on the inner side of the lips or the inner side of the cheeks in the mouth of the wearer of the device (i.e., a person). Thus, the target tooth alignment only needs to be adapted once, which increases the acceptance of the person for multiple devices. If the person still finds the target tooth alignment uncomfortable or inappropriate after the adaptation, the target tooth alignment can be corrected at an early stage (i.e., at the beginning or the first third of the treatment). The acceptance of the user increases because the user can see or feel the result at the end of a long treatment at the beginning of the treatment.

[0062] A doctor and / or an orthodontist and / or a person can at any time identify how far the actual state of a tooth is from the target tooth state based on the position of a recess in the device, because, for example, the distance of the recess to the frontal target plane is shortened. A dentist or an orthodontist can observe how close the actual state is to the target tooth position, in particular at the front of the dental veneer, by comparing the actual state of the tooth with the target tooth state shown by the dental veneer.

[0063] The dental veneer can be designed on its outer surface like the outer surface of the target alignment, or designed slightly differently, for example, due to the magnification to be considered and / or within the manufacturing tolerances and / or within a deviation range of less than 1 mm or less than 0.5 mm. When the relevant tooth has reached its final position and should not be changed by a structure or an attachment in the final treatment, a very thin dental veneer can be used. Breaks (Durchbrüche) can also be used in the dental veneer so that the tooth surface that has reached its final position is no longer covered by the veneer, but the tooth surface is arranged to be freely visible from the front.

[0064] The set of devices can include a pair of devices. Alternatively, multiple devices can be used for the lower jaw or the upper jaw, for example, a left device and a right device. In this case, the dental veneer can be arranged, for example, in the canine region.

[0065] In particular, there can be the following dental veneers / veneers or anterior tooth replicas:

[0066] - For example, as observed from a person, the first upper anterior dental veneer or anterior tooth replica (tooth body) of the upper left anterior tooth, and / or

[0067] - For example, as observed from a person, the first lower anterior dental veneer or anterior tooth replica (tooth body) of the lower left anterior tooth, and / or

[0068] - For example, as observed from a person, the second upper anterior dental veneer or anterior tooth replica (tooth body) of the upper right anterior tooth, and / or

[0069] - For example, as observed from a person, the second upper anterior dental veneer or anterior tooth replica (tooth body) of the upper left anterior tooth.

[0070] 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 veneer can have the same position relative to the human skull / facial features (in particular, the facial features determined by the skull features, i.e., in particular the features for determining the target alignment).

[0071] According to an improvement, when replacing the device pair in a person's mouth, at least one veneer of the second device pair can be located in the mouth at the same position as at least one veneer of the first device pair.

[0072] A third device pair of the kit can be located in sequence after the second device pair. The third device pair can also include at least one veneer that is configured to be similar to at least one veneer at the first device pair and / or similar to at least one veneer at the second device pair.

[0073] The order of the devices can be pre-determined by a treatment plan. At the end of the treatment, only one device can also be used instead of using a device pair.

[0074] The device can or should remain in the mouth during eating. This makes it possible for a person to have a better bite from the beginning. The mechanical stability of the device can withstand the chewing force, especially compared to devices / aligners made of a film by a deep-drawing process, and this is especially the case for devices milled from a stable material by a milling process. After eating or during daily tooth cleaning, the device or the currently worn device can be removed from the mouth so that it can be more easily cleaned, and the teeth or the remaining tooth structure can also be more easily cleaned.

[0075] Alternatively, the device can be removed from the mouth during eating.

[0076] The device can be set to be worn at least 15 hours, at least 20 hours, or at least 22 hours per day when it is its turn.

[0077] According to another improvement, at least a part of the device / device pair, at least half of the device pair or all device pairs, in particular a part of the upper jaw device and / or a part of the lower jaw device, can be manufactured using a subtractive manufacturing method (i.e., a method of selectively removing material from a workpiece during the manufacturing process) or using an additive manufacturing method (i.e., a method of selectively depositing material at the workpiece during the manufacturing process). In the first device pair and / or the second device pair, there may be undercuts, for example, that cannot be easily manufactured using a deep drawing process. Alternatively or additionally, in some devices of the device or device pair, there may be a material layer thickness difference of more than 2 mm or even more than 4 mm relative to the vertical direction (i.e., the height direction, for example) of the human head at the center of the occlusal surface. This cannot be easily achieved in the deep drawing process, in which a relatively thin film is placed on a mold and then deformed, for example, by pressure, vacuum, and / or the use of temperature (e.g., a temperature greater than 90 °C or greater than 100 °C).

[0078] The milling process can leave cutting marks or milling marks that are visible to the naked eye or only visible under a microscope. A polishing process can be used to smooth the outer surface. The maximum layer thickness at the center of the occlusal surface can be at least 50%, at least 100%, at least 200%, at least 300%, or at least 400% of the minimum layer thickness at the center of another occlusal surface of the same device (in particular the same upper jaw device or the same lower jaw device). Since the device can be directly manufactured by a subtractive method, additional forming (negative), such as in the case of deep drawing, is no longer required.

[0079] 3D (three-dimensional) printing processes (such as lithography, such as stereolithography) are particularly suitable as additive manufacturing methods, in which a liquid photosensitive plastic is hardened layer by layer with light or a laser to directly manufacture the devices of the kit.

[0080] Health-friendly plastics (such as synthetic resins, such as acrylic resins, epoxy resins, or vinyl ester resins, polyurethane PU, PMMA (polymethyl methacrylate)) are suitable as materials for the devices.

[0081] According to the improved solution, the first device (e.g., the first pair of devices) and the second device (e.g., the second pair of devices) or at least half of the devices / devices pairs or all devices / devices pairs include at least one dental veneer, which causes, at a person's teeth, in the covered area (i.e., previously substantially invisible), the application of the tooth alignment function and the displacement function relative to at least one dental arch of the person. The force transmission functional element (e.g., a functional element that interacts with the teeth using an attachment or acts directly on the teeth, e.g., a protrusion or a working surface in a recess for the tooth) can press the teeth in the corresponding direction. Here, at least one of the two dental arches of the person can be brought into a new condition, e.g., while the previously visible position of the dental veneer remains the same or only changes slightly, preferably with a total deviation of less than 0.6 mm or less than 0.4 mm during the entire kit process or during a longer sub - part of the kit that includes at least 20% of the devices (e.g., at least 5 devices). The alignment function and / or the displacement function can be gradually changed between successive steps of the kit in the accommodation area or recess for the teeth in the device / devices pair, while the relevant area was previously covered by the veneering element or the dental veneer.

[0082] For example, the dental veneer can be arranged at at least two, at least three, at least four, at least five or at least six tooth positions, e.g., at at least one anterior tooth position, two anterior tooth positions and / or at least one canine tooth position.

[0083] According to the improved solution, at least in a part of the device, in the molar region of the maxillary device and / or the mandibular device, a combination consisting of a structure with a height function and a structure with a sliding function and / or a combination consisting of a structure with a height function and a structure with a maxillo - mandibular relative positioning function or a ramp function is configured such that the combination achieves the migration of the contact plane and the future occlusal plane relative to the initial treatment state, and in particular achieves the cranial and / or facial optimization of the occlusion mechanism (relative to the person's face). The structure can have a layer thickness / height towards the occlusal surface, which is at least 2 mm, at least 3 mm or at least 4 mm. This layer thickness / height or, where applicable, the layer thickness difference related to other areas of the same maxillary device or the same mandibular device can be advantageously manufactured using subtractive manufacturing methods or additive manufacturing methods.

[0084] According to the improvement scheme, at least a part of the device has or has a colored function coloring at at least a part or all of the previously visible veneer element or dental veneer of the device. The coloring can preferably be achieved as an effect of material selection or by coating (such as painting) an external material layer of the device pair or at least a part of the device. The coloring can include a white component and / or a yellow component. The coloring can be different from transparent and / or translucent coloring. The coloring can be an aesthetically pleasing and attractive coloring. However, a translucent layer can enhance the impression of natural teeth. The color can be implemented using health-friendly colors (for example, dyes used for or available for coloring food).

[0085] According to the improvement scheme, at least one device of the kit (such as a mandibular device) or a device pair, preferably at least one device pair among the first 20% of the device pairs of the kit, respectively has at least one designed veneer element / dental veneer or multiple dental veneers, and the veneer element / dental veneer or multiple dental veneers completely or mostly cover the teeth and / or tooth roots of a person in the previously visible area, so as to migrate behind the veneer element / dental veneer or multiple dental veneers in the covered area of these teeth and / or tooth roots. The migration preferably consists of a superposition of translation and torsion step by step, so as to guide the teeth and / or tooth roots in the covered area to the target position. Therefore, when observed from the front, in addition to its stabilizing function, the veneer element or dental veneer can cover these processes. Through covering / veneer, for a third party, these processes can be completed almost invisibly.

[0086] According to the improvement scheme, at least a first part of the device can be configured such that at the molars of a person, a height structure is first implemented through a height function. The height structure can be suitable for increasing the distance between the mandible and the maxilla in contact occlusion, and cause the unlocking of the previously blocked tooth migration. At least another part of the device pair, especially a part different from the first part, can be configured such that this unlocking (release) achieved especially by the height function enables the migration of the teeth or tooth roots of a person through an alignment function as part of a subsequent device / device pair and / or a change in the dental arch of a person through a displacement function as an additional part of a subsequent device. The tooth migration can be suitable for bringing the entire set of teeth of a person closer to the target alignment or an intermediate target tooth alignment.

[0087] According to the improvement scheme, in at least a part of the device (such as a device pair), in addition to the alignment function and / or the displacement function, the height function can also be combined with a sliding function. Therefore, at least a part of the device pair can have sliding surfaces on the left and right, and at least a local area of the sliding surface is smooth and / or unencrypted, so that the sliding surface can cause a neuromuscular stability requirement of the mandible relative to the maxilla when an active contact force is applied by the wearer or a person of the device in this area. For a person, the stability requirement can lead to an actual neuromuscular relearning of the position of the occlusal plane.

[0088] Although the mutually facing sliding surfaces of the upper and lower devices may be constructed complementary to each other, there may be an asymmetry between the left and right of elements (such as height structures different from each other) for defining the entire sliding surface. Encryption may mean the existence of elevations and depressions whose heights correspond to natural tooth grooves or tooth protrusions. Elements that are symmetrical to each other left and right may also be used to define the entire sliding surface.

[0089] According to an improvement, in at least one part of the device or pair of devices, in addition to the alignment function related to a person's individual teeth and / or the displacement function related to a person's dental arch, a ramp function may also be integrated. The relevant ramp may particularly have a ramp surface that is vertically or predominantly vertically oriented. The lateral surface or the predominantly lateral surface of the ramp may achieve the required distance between the lower jaw and the upper jaw. The ramp function may be adapted to generate a lateral reaction force under the contact force between the lower jaw and the upper jaw due to, for example, an inclined plane locally observed at the ramp, and this lateral reaction force causes the lower jaw to move left and right and / or forward and backward relative to the upper jaw at least in one of the combined lateral directions. Therefore, a change in the position of the lower jaw relative to the upper jaw can be achieved, where it is not necessary to change the dental arches of the lower jaw and / or the upper jaw, although in applicable cases it may also be changed.

[0090] According to an improvement, the last device or the last pair of devices of the kit may be constructed to achieve an imitation or as accurate an imitation as possible (for example, taking into account magnification and / or manufacturing tolerances) of the planned final medical body or the target tooth state or the target tooth alignment, for example in order to complete the treatment with the devices of the kit. Alternatively or additionally, an intermediate target tooth state may also be used. At least in the visible anterior tooth region, the imitation of the final medical body may be achieved by a front veneer element or a front tooth veneer, which is preferably shaped according to the planned final medical body and optionally tooth-colored or stained according to the planned final medical body by means of a color function. The front veneer element or the front tooth veneer may be replaced in the final medical body, for example, by a permanent or fixed medical body, for example in order to complete the overall treatment. Thus, the following elements may be used: Table Top (height construction), Onlay (using a ground tooth surface), Vernier (front veneer), Verkronung, Brücke, implant, especially combinations of the above elements, etc. Blockages on multiple teeth in the final medical body may be avoided as much as possible because this would be disadvantageous as it may, for example, damage the fine retention fibers (perforating fibers) of the teeth.

[0091] For example, "as accurate an imitation as possible" may mean "within the manufacturing tolerances" and / or taking into account the above-mentioned magnification and / or taking into account dental technical conditions.

[0092] According to the improvement scheme, the last device or the last pair of devices of the kit can be configured such that an as-accurate-as-possible imitation of the planned final medical body of a human tooth is achieved, wherein the imitation of the final medical body is achieved at least in the molar region by molar elements, in particular molar veneer elements or groups of such elements, for example, in order to complete the treatment with the devices of the kit. Alternatively or additionally, an intermediate target tooth state can also be used. These molar elements (groups) can have, for example, an occlusal surface geometry and an occlusal surface orientation based on the cranial geometry and / or anatomy of the human skull according to the planned final medical body or the intermediate target tooth state. These provisional molar elements (veneers) in the molar region can be replaced, for example, by dentures in the final medical body.

[0093] Medical imitation methods that take into account bone density (such as X-ray density) can be used. For example, segmentation can be achieved by Hounsfield X-ray density units to determine, for example, cranial features (such as orbits and / or inner ears), see, for example, Hornung (EP 3 332 731 A1) and Saxler WO 2020 / 141134 A1, which are incorporated herein by reference for all legal purposes.

[0094] In particular, the aim can also be to continuously or permanently change the position of the occlusal plane, i.e., also after the final medical body, in particular with respect to its inclination in the frontal plane and / or with respect to its inclination in the sagittal plane and / or its height position.

[0095] According to the improvement scheme, in at least a part of the pair of devices, there can be (in particular solidly implemented or hollowed out in the inner part) height profile elements or material thickenings at the occlusal surface, i.e., for example, protrusions that are at least twice the layer thickness / height at other occlusal surfaces of the same upper jaw device or the same lower jaw device. The total layer thickness / height of the area of the height profile element / material thickening is preferably greater than 2 mm or greater than 3 mm or greater than 4 mm. In other areas of the device, the maximum layer thickness of the occlusal surface or the height of the height profile element can be, for example, less than 2 mm, or even less than 1 mm. The height profile element or material thickening preferably can be present in the first pair of devices of the kit and / or in at least one pair of devices among the first 20% of the devices of the kit.

[0096] The height profile element can be realized by a material thickening (i.e., by more material relative to other regions). Alternatively, a cavity can also be used to realize the height profile element, which has the same function as the material thickening made of solid material. For example, in the case of the height profile element at the mandibular device, the cavity can be realized, for example, between the occlusal surface and the inner side of the occlusal wall / top facing the occlusal surface, or, for example, in the case of the height profile element at the mandibular device, the cavity can be realized between the occlusal surface and the inner side of the wall / bottom of the height profile element facing the occlusal surface.

[0097] According to the design, compared with the previous device or compared with the initial state of a person's teeth, a height transition part of the height profile element or the material thickening can be used. The height transition part of the height profile element or the thickening can be 3 mm to 6 mm.

[0098] According to the improvement, in the same maxillary device or the same mandibular device, at the same molar position, there can be height profile elements or thickenings with different heights from each other on the left and right. The height difference can preferably be at least 1 mm (millimeter), at least 2 mm or at least 3 mm. Thus, the asymmetry of a person's occlusion mechanism can be taken into account, for example, in order to reduce or eliminate this asymmetry. The asymmetry of the height profile element or the thickening can also cause pivoting due to the torsion of a person's mandible relative to the maxilla. Alternatively, height profile elements or thickenings with the same height can be used on the left and right, that is, the height profile elements / thickenings are symmetric with respect to each other left and right.

[0099] The left - right system of the wearer of the device pair can be used as a reference system. Alternatively, the left - right system of the previous observer (such as a dentist, a technician, an orthodontist) can also be used.

[0100] According to the design, the first anterior dental veneer of the first device or the first pair of devices may include a first recess / accommodation area for the anterior teeth of a person. The first anterior dental veneer of the second device or the second pair of devices may include a first recess / accommodation area for the same anterior teeth of a person. At least the labial outer surface of the first anterior dental veneer of the first device may be designed to be the same as or only slightly different from the labial outer surface of the first anterior dental veneer of the second device. The first recess of the first anterior dental veneer may have a first position relative to the labial outer surface of the first anterior dental veneer. The first recess of the second anterior dental veneer may have a second position relative to the labial outer surface of the second anterior dental veneer. Due to the translation of the person's teeth along the anteroposterior axis relative to the person's head, the first position may be different from the second position. The first anterior dental veneer of the first device may have a first material thickness, particularly in the first recess / accommodation area, in the labial direction. The first anterior dental veneer of the second device may have a second material thickness, particularly in the first recess / accommodation area, in the labial direction, and the second material thickness is preferably measured at the same position as the measurement position of the first material thickness in the first device / first pair of devices in the second device / second pair of devices. The first material thickness may differ from the second material thickness by at least 20% or at least 50%. This may be due to the fact that the anterior dental veneer remains substantially unchanged in its front region, but the translation of the anterior teeth occurs at its rear (e.g., from back to front or from front to back). This also applies to the anteroposterior inclination or torsion of the anterior teeth (i.e., the change in the layer thickness at the front side of the anterior dental veneer).

[0101] The change in the thickness of the material layer at the front side may be compensated by an opposite change in the material layer thickness at the rear side of the dental veneer, for example, in order to keep the overall stability of the device unchanged. Thus, when the layer thickness in the front region decreases, the layer thickness in the rear region of the dental veneer may increase, and when the layer thickness in the front region increases, the layer thickness in the rear region of the dental veneer may decrease. However, the material layer thickness in the rear region may also remain unchanged, for example, depending on dental technical conditions or other conditions.

[0102] According to an improved embodiment, the maxillary device of the first device or the first pair of devices or the mandibular device of the first device or the first pair of devices may have at least one second anterior dental veneer on its front side, which is adjacent to the first anterior dental veneer of the first device or the first pair of devices (e.g., the first veneer element described above). The maxillary device of the second device or the second pair of devices or the mandibular device of the second device or the second pair of devices may have at least one second anterior dental veneer on its front side, which is adjacent to the first anterior dental veneer of the second device or the second pair of devices (e.g., the second veneer element described above).

[0103] In addition, for a total of four recesses / accommodation areas, the following applies:

[0104] - wherein, the first anterior tooth veneer of the first device includes a first recess for the first anterior tooth of a person, or is adjacent to the first recess / accommodation area,

[0105] - wherein, the second anterior tooth veneer of the first device includes a second recess for the second anterior tooth of a person, or is adjacent to the second recess / accommodation area, wherein the second anterior tooth is located beside the first anterior tooth,

[0106] - wherein, the first anterior tooth veneer of the second device includes a first recess for the first anterior tooth of a person, or is adjacent to the first recess / accommodation area, and

[0107] - wherein, the second anterior tooth veneer of the second device includes a second recess for the second anterior tooth of a person, or is adjacent to the first recess / accommodation area.

[0108] The two anterior tooth veneers of the first device can be the same as the two anterior tooth veneers of the second device at least at the occlusal surface and / or the labial surface. Equality can exist with respect to the maximum width of the occlusal surface and / or the maximum width of the labial surface and / or the distance between adjacent occlusal surfaces from each other and / or the distance between adjacent labial surfaces from each other. This equality can be due to the external contour or external geometry of one or more veneers (especially in its anterior region) not changing.

[0109] The two recesses of the first device pair can be spaced from each other by a first distance, especially a minimum distance. The two recesses of the second device pair can be spaced from each other by a second distance, especially a minimum distance. The magnitude of the first distance can differ from the magnitude of the second distance by at least 20% or at least 50%. Due to the translation of the first anterior tooth of a person relative to the person's head along the left - right axis and / or the translation of the second anterior tooth along the left - right axis, the first distance can be different from the second distance. In this translation or these translations, it can also preferably result in the magnification or reduction of the distance between the two anterior teeth of a person.

[0110] As described above, the anterior tooth veneer / veneer element can remain unchanged especially in its frontal contour / geometry. However, the distance between the recesses can change. The change in the distance between the recesses can be directly caused by the translation of the anterior tooth or anterior teeth in its posterior region while the anterior tooth veneer remains basically unchanged in its anterior region. The translation can be, for example, to the right or to the left, or one tooth can be shifted to the right and the other tooth can be shifted to the left. Thus, the gap between the two anterior teeth can be closed, or the distance between the two anterior teeth can be enlarged. This also applies to the left - right inclination or torsion of the anterior tooth or anterior teeth, that is, to the change in the distance between the recesses in the anterior tooth veneer, but its external contour can remain unchanged.

[0111] Here, if the stability is reduced due to a decrease in the distance between the recesses, but the overall stability of the device can be maintained if the stability is increased again by a corresponding material addition in other areas (e.g., in the lateral areas of the recesses of the device or of one or more veneers).

[0112] According to another improvement, at least one device / device pair, at least two device / device pairs, at least three device / device pairs, at least four device / device pairs or at least 10 device / device pairs can be arranged in the order of the devices of the kit between the first device or the first device pair and the second device or the second device pair. Thus, the difference in the thickness of the material layer and / or the difference in the recess distance on multiple devices can be changed significantly and thus easily measurable or verifiable, for example by at least 0.5 mm or at least 1 mm or at least 2 mm.

[0113] According to an improvement, in at least a part of the device / device pair or in all device / device pairs, at least one veneer element or at least one veneer or multiple veneer elements / multiple veneers can uniformly comprise a single material. This can simplify the manufacturing.

[0114] According to an alternative improvement, in at least a part of the device / device pair or in all device / device pairs, at least one veneer element or at least one veneer or multiple veneer elements / multiple veneers can each comprise at least two different materials. Thus, a first material can be present in the outer area, and a second material can be present in the inner area surrounded by the outer area of one or more veneers. The first material has a greater hardness compared to the second material. Alternatively, the second material has a greater hardness compared to the first material. There can be a standardized method for determining the hardness (e.g., for determining the Shore hardness, especially in the case of using type A or D). Alternatively, a non-standardized method can also be used to determine the hardness.

[0115] When a harder material is used as the material (first material) in the outer area of one or more veneers, wear can be reduced, and the wearing comfort can be increased by the softer material inside.

[0116] If there are medical or other reasons, a softer material can be used in the outer area of one or more veneers.

[0117] According to the improved solution, the material in the internal region can extend over the entire dental arch or multiple tooth positions of the partial device of the device pair. The external region can be configured to be used successively for at least two mutually different internal regions. The external region can be used for, for example, at least 20% of the devices. A mechanical interface (e.g., a mechanical interface in terms of ports) can be defined between the internal region and the external region, and this mechanical interface is the same on at least two devices. Especially in the case of using a shape base and / or a clamping base, the internal region can be inserted into the external region and / or can be removed from the external region. Alternatively, additional fastening elements can also be used. Through this modular system, the manufacturing cost can be significantly reduced, and the total consumption of the devices in the manufacturing kit can be significantly reduced.

[0118] According to the improved solution, regarding the proximal free end of the mandibular device of the corresponding device / corresponding device pair, due to the expansion of the dental arch, the labial outer surface of the first dental veneer can have a different position in the sagittal section from the labial outer surface of the second dental veneer. The difference in position can be at least 1 mm or at least 1.5 mm. However, the position of the front side of the dental veneer can be substantially the same relative to the cranial reference system.

[0119] According to the improved solution, for example, by using the expansion of the dental arch, in the order of the devices of the kit, there can be no device or device pair or at least one device / device pair or at least two device / device pairs or at least three device / device pairs or at least four device / device pairs or at least 10 device / device pairs between the first device / first device pair and the second device / second device pair. On multiple devices, the total difference in position can be at least 0.5 mm or at least 1 mm or at least 2 mm.

[0120] According to another aspect, a method for designing a dental device is provided, especially a method for designing a multifunctional device. This method can be particularly suitable for designing the above-mentioned kit or a kit according to one of the above-mentioned improved solutions, where digital data can be generated. The design can be a preparatory stage for manufacturing one or more devices.

[0121] The method can include:

[0122] - Recording the initial tooth arrangement of the person's teeth in the upper jaw and / or the person's teeth in the lower jaw, preferably simultaneously recording at least one cranial feature and / or facial structure / feature in the cranial region of the person,

[0123] - Determining at least one reference structure of the person, preferably a cranial reference structure, before recording, during recording, or after recording,

[0124] - Determining the target tooth arrangement of the person's upper jaw teeth, especially relative to the person's upper jaw or the target upper jaw, considering the reference structure,

[0125] - Determining a target tooth alignment of the teeth of a human mandible, especially relative to a reference structure and in particular relative to a human mandible or a target mandible.

[0126] - Providing a series of data sets for the teeth of the upper jaw and / or the teeth of the lower jaw, the series of data sets consisting of groups of digital data sets (in particular, for example, pairs of digital data sets each having a data set) following one another in sequence, based on a starting tooth alignment and a target tooth alignment or a target shape and / or a target position of a target upper jaw and / or a target lower jaw.

[0127] The method can use the technical features given in claim 1 or the features given in claims 1 to 20.

[0128] The target tooth alignment can be used as a basis for manufacturing at least one veneer element / dental veneer (especially an anterior dental veneer), and, where applicable, also including a canine veneer or additional veneers / veneer elements for other teeth (such as premolars or molars).

[0129] According to an improvement, at least one veneer element or at least one dental veneer can be presented in a target tooth state or an intermediate target tooth state or the teeth at that tooth position at a suitable magnification of the target tooth state or the intermediate target tooth state. Regarding the magnification range, the above range can also apply to the method.

[0130] According to an improvement, at least one veneer element or at least one dental veneer can be used for at least one device or a plurality of devices of a kit of devices for gradually changing the tooth position of a human. Here, at least one device can be different from the last device of the kit, or a plurality of devices can be different from the last device of the kit.

[0131] Therefore, the technical effects mentioned above for at least one dental veneer of a kit consisting of devices can also be indirectly applicable to a method of designing a device including at least one veneer element or at least one dental veneer, that is, for example, a target tooth state can be used or presented in advance.

[0132] Suitable methods can be used to provide data, for example:

[0133] - Using collision detection with an OBB (Oriented Bounding Box) tree / graph, and / or

[0134] - Representing a three-dimensional structure using a Voronoi diagram.

[0135] Recording the starting - tooth alignment of the teeth can also include recording a bone image of the patient's head, which also shows the position of the mandible in the starting mandible position, the position of the maxilla in the starting maxilla position, and the positions of the teeth of the maxilla in the starting tooth positions and the positions of the teeth of the mandible in the starting tooth positions.

[0136] Determining a reference structure may include determining at least one reference plane taking into account the structure / structural features of at least one cranial bone of the human (patient)'s head or the facial structure features of the human's face, wherein the facial features are preferably closely related to the cranial structure.

[0137] Taking into account cranial features may be a prerequisite for long-term treatment success. The cranial structure is in particular the structure outside the upper jaw of the human and / or in particular the structure outside the lower jaw of the human. The cranial structure may:

[0138] - relate to features of the skull and / or head, such as the temporal region, ears, inner ear region, eye sockets, cheekbones, etc.,

[0139] - be suitable for determining the sagittal plane, such as the median sagittal plane through the skull, in particular at half the distance between features that occur in pairs (i.e., exactly between the determined inner ear regions or between the other features mentioned above, etc.),

[0140] - be suitable for determining a substantially transverse plane, such as the target occlusion plane, see EP 33 32 731 A1, which is incorporated herein by reference for all legal purposes.

[0141] The reference structure may for example include a Cartesian reference plane system, which was proposed in WO 2020 / 141134 for a training device, but can also be used for other purposes, such as for the proposed method. Document WO2020 / 141134 A1 is incorporated herein by reference for all legal purposes.

[0142] If for example the sagittal plane is known, a plane orthogonal thereto, such as at least one frontal plane or group of frontal planes and / or at least one transverse plane or group of transverse planes, can be determined.

[0143] 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 can be given in the treatment plan and can depend on for example whether attachments are used or the pressure on the teeth that the relevant person can still tolerate.

[0144] In the design, the method may further include at least one of the following steps:

[0145] - determining the force vectors required for tooth migration, for example using the finite element method (FEM) or the finite difference method (FDM) or other suitable computer-based methods.

[0146] - Based on the force vector, determine the shape of the recesses and / or force transmission elements (attachments and / or working surfaces in the projections and / or recesses) in the devices of a kit comprising at least two pairs of devices.

[0147] The devices related to this method can also be constructed like the above-mentioned devices, i.e., including an upper jaw device and a lower jaw device respectively, for example. Considering the force vector, the devices or pairs of devices can be designed such that they successively cause a gradual change in the position of a person's teeth in the order of device / pair of devices.

[0148] Mounting the attachments to the teeth can play an important role in the success of the treatment. Compared with the teeth, the attachments can be small fastening elements made of a composite material (i.e., a tooth-like substance), which ensure that tooth movement can occur faster, more easily, and more effectively. The attachments can be used as anchors, and the aligners grip the anchors to complete the movement, such as raising the teeth. The pressure required for tooth movement can be precisely applied through the attachments. In addition, the attachments can achieve complex movements, such as the torsion of teeth, and ensure that the correction is carried out without unnecessary "intermediate movements".

[0149] In principle, the treatment can be carried out without attachments. In some malpositions, attachments are not required at all and / or the attachments are omitted according to requirements or arranged at a later time point. Treatment without attachments can result in the need for more splints to achieve the target alignment.

[0150] Each digital data set or each pair of digital data sets can include:

[0151] - Data describing the tooth alignment of the teeth in the upper jaw, and / or

[0152] - Data describing the tooth alignment of the teeth in the lower jaw.

[0153] The successive tooth alignments in the upper jaw can gradually progress from the initial tooth alignment of the teeth in the upper jaw to the final tooth alignment or the target tooth alignment. The successive tooth alignments in the lower jaw can gradually progress from the initial tooth alignment of the teeth in the lower jaw to the final tooth alignment or the target tooth alignment.

[0154] According to an improvement, the method can preferably be used for treating malpositions and / or aging phenomena at a person's full set of teeth. Other applications are also feasible.

[0155] According to an improvement, a multifunctional overall treatment plan can be formulated, which integrates multiple functions into the devices of the kit. Each of the functions can include a sub-treatment plan, which is related to the tooth positions of a person's individual teeth or full set of teeth.

[0156] The overall treatment plan can describe which of the multifunctional capabilities are activated when and / or to what extent, where at least two, at least three, at least four, at least five, or at least six functional types can be selected from the following groups and integrated:

[0157] - Alignment function, where the migration of at least one tooth is achieved by smaller gradual displacements, smaller gradual tilts, or smaller gradual torsions through at least a part of the device or through all of the devices, where the gradual amount is preferably less than 0.3 mm (millimeters) or less than 0.2 mm, and / or

[0158] - Displacement function, where the large-scale displacement of teeth is achieved through tilting and translation and optionally tilt correction through at least a part of the device or through all of the devices to migrate or change the dental arch, where the dental arch migrates at least 1 mm or at least 2 mm, or is extended at least 1 mm or at least 2 mm, and / or,

[0159] - Shape function, where the shape of at least a part or all of the devices of the kit is designed using dental veneers preferably arranged in the perceptible front region and / or in the visible region for aesthetic design, where preferably the dental veneers cover the teeth or tooth roots, and / or

[0160] - Color function, where at least a part or all of the devices have a separate color in at least the front-visible dental veneers of the device pair or at least at the front-visible dental veneers of the device pair, especially having the color of human teeth or other attractive tooth colors, such as aesthetic, attractive colors, especially having a color different from colorless transparent or colorless translucent materials, and / or

[0161] - Height function, where a solid structure with material is implemented in the molar region of the device or a part of the device, preferably on the molars, where the structure preferably has a layer thickness of at least 2 mm or at least 3 mm or at least 4 mm, and / or

[0162] - Sliding function, where a solid structure with a constructed sliding surface is used in at least a part of the device, preferably the solid structure has a layer thickness of at least 2 mm or at least 3 mm or at least 4 mm and / or has low friction and / or no retainers (recesses, grooves, profiles), and / or

[0163] - Maxilla-mandible relative positioning function, preferably a ramp function, where locally inserted ramps, inclined planes, springs, or other elements that generate lateral reaction forces in the contact between the maxilla and the mandible are used in at least a part of the device, and / or

[0164] - Implant function, in at least a part of the device, the implant function has a supporting function and / or fastening function and / or positioning function at the implant of a human for the maxillary device or the mandibular device of the device pair, wherein preferably, the implant mainly bears axial loads, and / or

[0165] - Supporting function, especially when teeth are missing at important positions in the dental arch, in at least a part of the device or in all device pairs, the supporting function provides a supporting function for at least one of the maxillary device or the mandibular device in the device on the soft tissue of a human.

[0166] Additional functions can be selectively added, such as an orthosis function, such as the Saxler orthosis, see WO2020 / 141134 A1, 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 marking / marking / ruler) or other methods. The orthosis can include an edge gap, but this is not necessary.

[0167] In at least one sub-part of the kit, the alignment function for orthodontic action and the shaping function for aesthetic action can be applied simultaneously and integrated into the device.

[0168] At least one or more of the above-described improvement solutions for the kit can equally apply to the method:

[0169] - The force transmission functional element for the alignment function and the displacement function is covered by at least one dental veneer,

[0170] - Especially in the molar region of the maxillary device and / or the mandibular device, a combination composed of a structure with a height function and a structure with a sliding function and / or a combination composed of a structure with a height function and a structure with a ramp function,

[0171] - Coloring,

[0172] - The designed dental veneer included in at least one of the first 20% devices in the kit,

[0173] - First implement the height structure by means of the height function, and then implement appropriate tooth migration through one or more alignment functions and / or implement appropriate dental arch changes through one or more displacement functions,

[0174] - In addition to the alignment function and / or the displacement function, there are also the height function and the sliding function,

[0175] - In addition to the alignment function and / or the displacement function, there is also the maxillary-mandibular relative positioning function (for example, the ramp function),

[0176] - The last device of the kit is an as-precise-as-possible imitation of the planned final medical prosthesis in the visible anterior tooth region, and / or

[0177] - The last device of the kit is an as-precise-as-possible imitation of the planned final medical prosthesis of a human tooth in the molar region.

[0178] According to the improvement scheme, after wearing the last device pair, the final medical prosthesis of a human tooth and / or tooth root can be achieved according to the treatment plan. The final medical prosthesis can create a permanent occlusal surface consistent with the planned occlusal surface. The final medical prosthesis can create a front surface consistent with the planned front surface, in particular consistent with the shape and / or position of the labial outer surface of at least one anterior veneer and / or consistent with the shape and / or position of the labial outer surface of the second anterior veneer.

[0179] According to another aspect, a manufacturing method is provided, which can be used to manufacture the above-mentioned kit and / or a device based on a kit designed according to one of the above methods. Therefore, the above technical effects can also be applied to the manufacturing method. A subtractive manufacturing method can be used to manufacture a kit composed of devices or device pairs or at least a part of the device, such as more than half of the device. A subtractive cutting method, in particular milling, can be used. Alternatively, an additive manufacturing method, in particular 3D (three-dimensional) printing, can be used. The above technical effects of the method are also applicable here, for example, it is easy or easier to make undercuts and / or layers with different thicknesses at the center of the occlusal surface.

[0180] All devices can be produced at the same manufacturing location, for example, on the same machine. This can simplify logistics, for example. Alternatively, the first part of the device can be produced at the first manufacturing location, and the second part of the device can be produced at the second manufacturing location, for example, in order to ensure the rapid availability of the first device and, where applicable, one or two additional devices on the one hand, and to reduce the overall manufacturing cost by using low-cost manufacturing on the other hand. In addition, when the relevant device can be manufactured in this technology, a traditional deep-drawing process can also be used to manufacture some devices of the kit, for example, when the shape function (one or more veneers) has not yet been integrated.

[0181] According to another aspect, the following unit is provided:

[0182] - A computer, which includes: at least one storage unit, and

[0183] A control unit, which is designed to execute the instructions of a program, and the instructions cause the computer to execute at least a part of one of the above methods, in particular to execute the steps related to the design of the device, in particular automatically or semi-automatically.

[0184] - A computer program comprising machine-readable instructions which, when executed by a control unit, cause the control unit to execute at least a part of one of the above methods.

[0185] - A computer program product comprising machine-readable instructions which, when executed by a control unit, cause the control unit to execute at least a part of one of the above methods, and / or

[0186] - Digital data, in particular design data and / or manufacturing data for manufacturing a device pair using a manufacturing machine, which is generated by one of the above methods or is required by such a method.

[0187] According to another aspect, digital data is provided for describing a kit consisting of devices for gradually changing the position of a person's teeth. The digital data can describe a device or a device pair, which respectively includes an upper device and / or a lower device.

[0188] The upper device is designed such that it can be mounted on the dental arch in a person's upper jaw. The lower device can be designed such that it can be mounted on the dental arch in a person's lower jaw.

[0189] The device or the device pair can be designed such that when the device or the device pair is successively worn by a person in a predetermined order according to the device or the device pair, the device or the device pair causes a gradual change in the position of the person's teeth.

[0190] The digital data can preferably describe at least one first dental veneer or at least one veneer element at the front side of the upper device of the first device or the first device pair or the lower device of the first device or the first device pair.

[0191] The digital data can preferably describe at least one second dental veneer at the front side of the upper device of the second device or the second device pair or the lower device of the second device or the second device pair.

[0192] Similarly, a third dental veneer / veneer element of a third device pair or a third device can also be described.

[0193] At least one dental veneer of the first device or the first device pair can be located at the same tooth position as the dental veneer of the second device or the second device pair. In addition, the digital data can reproduce the technical features described in claim 1 or the technical features given in claims 1 to 20.

[0194] At least one dental veneer of the first device or the first device pair and at least one dental veneer of the second device or the second device pair can be presented on the teeth at that tooth position in a target tooth state or an enlarged target tooth state.

[0195] According to another aspect, there is provided a treatment plan, in particular a digital treatment plan for gradually changing the position of a person's teeth, in particular a treatment plan using a kit according to one of claims 1 to 20 or a method according to one of claims 21 to 33.

[0196] The treatment plan can describe the treatment process of a person. The treatment plan can determine the following data at least in sub - parts or throughout the treatment plan:

[0197] - The number of the devices or pairs of devices of the kit,

[0198] - The identification of the tooth positions within the corresponding devices or corresponding pairs of devices, and

[0199] - The determination of the treatment function for the corresponding tooth positions of the corresponding devices or corresponding pairs of devices,

[0200] wherein the treatment plan includes a shaping function as a treatment function, which determines the shape of at least two veneers or at least three veneers, in particular the shape of the anterior veneers,

[0201] and wherein at least one veneer of the first device or first pair of devices is located at the same tooth position as the veneer of the second device or second pair of devices and / or the veneer of the third device or third pair of devices.

[0205] The treatment plan can include a data set, or be based on a database, in particular a relational database. Alternatively, the digital data or digital treatment plan can also be described by other suitable means and methods.

[0207] The technical effects given above for the kit and method or other aspects also apply equally to the digital data and digital treatment plan.

[0208] Although the present invention has been described in detail and illustrated by preferred embodiments, the present invention is not limited to the disclosed examples, and those skilled in the art can derive other variations therefrom without departing from the scope of protection of the present invention.

[0209] The same reference numerals denote the same technical features, unless otherwise specified. In this application, "can" represents both the possibility of implementation and the actual technical implementation. The concepts of the present disclosure are described in a specific context according to preferred implementation examples, namely, aligners. However, the disclosed concepts can also be applied to other situations and / or arrangements, especially in cases where alignment is not required.

[0210] The above has widely explained the features and technical effects of the present invention. The following will explain additional features and technical effects of the embodiments of the present disclosure, such as the subject matter of the claims.

Those skilled in the art should also recognize that equivalent structures should not deviate from the spirit or scope of the present disclosure, such as as defined in the appended claims.

[0211] To more fully understand the disclosed concepts and their technical effects and advantages, reference is now made to the following description in conjunction with the accompanying drawings. The following drawings are schematic diagrams of complex multi-dimensional methods and multi-functional devices. In principle, these drawings can only reflect partial aspects of the shown implementations of the devices and methods.

[0227] Figure 15 shows a device having a height function, a ramp function, a sliding function, an alignment function, and a shape function, and

[0228] Figure 16 shows a computer system.

[0229] Those skilled in the art are faced with a variety of requirements and objectives that should be combined to be achieved. The above detailed presentation of the prior art shows that for each of these sub-domains, very feasible methods are known and equally feasible devices can be available. However, the devices and methods available so far can only meet some of the requirements separately. The integrated combination of elements and measures in a single device or in a gradually changing set of devices has so far been unknown and unavailable, especially without the resulting synergistic effects.

[0230] The proposed technology can demonstrate a significant and very important expansion of the functional range of devices for the optimization of the entire dentition or the entire occlusion mechanism. For the pure alignment function 210, which can be supplemented by classical orthodontic functions 220 such as traction devices, as now proposed, the option of adding at least one, preferably at least 2, particularly preferably at least 3 additional functions can be provided.

[0231] In particularly complex embodiments, 4 or 5 or 6 function types can be combined. For example, the preferred additional functions can be selected from the following group: shape function 230, color function 240, height function 250, CMD function, and cranial function. A particularly preferred combination of function types is the alignment function 210, shape function 230, height function 250, color function 240, and CMD function.

[0232] From a biomechanical and orthopedic perspective, the effects of combined treatment can even extend beyond the occlusion mechanism. Combined treatment does not only involve the teeth, jaw joints, and skull. Combined treatment also involves the atlas, cervical vertebrae, and other parts of the locomotor apparatus (Bewegungsapparat), particularly the thoracic and lumbar vertebrae, for example up to the sacrum. The preliminary results of this combined treatment show that through cranial optimization, spinal misalignments can also be improved.

[0233] Described systematically and schematically, the multi-functional integration method can include treatment periods, particularly periods of treatment planning, characterized by multiple different functions. Thus, such treatment planning is not presented only on one level for each tooth in the dentition. A complete-level treatment plan can be created for each function that optionally acts on the teeth, for example by numbering the teeth from left to right and numbering the devices or device pairs or device stages from top to bottom. Thereby, in addition to the numbering of the individual teeth and the numbering of the devices or the numbering of the individual device pairs, a "third dimension" of the treatment plan is given by the multiple functions. This is too comprehensive for a given scope description. Therefore, the presentation focuses on different function types or functionalities, i.e., on multiple levels of the treatment plan, where different function types can have different effects on each tooth in the entire dentition.

[0234] In general, different from comparative-alignment clamping, the proposed solution can include an integrated multidisciplinary diversity of functions that are in the sequence of device pairs 10.n (n = 1…x) each having a maxillary splint (maxillary device) 11.n and a mandibular splint (mandibular device) 12.n. Three groups of functions will be explained in detail below. Additional functions can be added. Similarly, some of the functions explained can be used optionally, i.e., when needed.

[0235] Migration functions Alignment 210 and Displacement 220

[0236] Classical orthodontic functions can be part of the function selection to be combined. The alignment function 210 involves the migration of at least one tooth relative to the dental arch, in particular relative to adjacent teeth. Thus, even with only an oral scan of the surfaces of the dental arches of the upper jaw OK, 5 and the lower jaw UK, 4, the alignment function 210 can be displayed. By installing so-called attachments at the teeth, the possible forces and moments applied to the teeth can be selectively changed.

[0237] The displacement function 220 involves the migration of a single tooth driven by forces that interact with the opposite side, such as through rubber bands or side wedges. The combination of the alignment function 210 and the displacement function 220 is also part of the new combinations that can be proposed in the multifunctional method and the multifunctional device 10.

[0238] 1) Function type Alignment function 210 (Alignment function): At least one device pair 10.n has alignment elements (in particular alignment cavities or material recesses) for the accommodation and force guidance of teeth. The alignment elements can interact directly with the selected teeth or with the attachments installed at the selected teeth.

[0239] 2) Function type Displacement function 220 (Migration): At least one device pair 10.n has a force application element with an additional function. The force application element with the additional function preferably acts between the upper jaw and the lower jaw. The force application element with the additional function can be configured as a guiding wedge or a traction rubber, etc.

[0240] Function Shape 230 and Color 240

[0241] Two particularly striking new functions are emphasized. One or two functions are integrated, which can have both technical effects and affect aesthetics: the shape function 230 of the new tooth shape and the color function 240. The shape function 230 can be achieved by the fact that the outer shape of the veneer does not in principle follow the pre-determined outer shape of the teeth of person P in the actual state, and the veneers together form the device. More precisely, in particular by replicating at least one target tooth arrangement, the shape of each veneer can be optimized or repaired in the device 10. For example, in the case of a full set of teeth with worn teeth, this can be advantageous in order to later achieve a suitable height of the occlusal surface.

[0242] The second function is the color function 240. The color function can include not only the actual color of the veneer, but also the complex color effects produced by the teeth. Here, each veneer can obtain its own color function, and basically this color distribution can vary from device n to device n + 1 in the kit 100.

[0243] 3) Functional type Shape function 230 (Shape): At least one device for 10.n can have an artificially shaped dental veneer or an artificially shaped dental component, herein referred to as a dental veneer or dental body, in particular a replica of at least one target - tooth arrangement. The maxillary splint 11 and / or the mandibular splint 12 can include a plurality of specially shaped dental veneers here. The dental veneers can cover the accommodation areas of the teeth or tooth roots such that their relative movement takes place step - by - step behind the scenes. Dental veneers are also used to fill gaps and provide load - bearing dental veneers for implants. Thus, shape - correction, in particular shape - correction of the external geometry, can be carried out simply and economically at an early stage when needed.

[0244] 4) Functional type Color function 240 (Color): At least one device for 10.n has dental veneers equipped with individual color characteristics. The color characteristics of the dental veneers can vary from tooth to tooth. In particular, the front teeth can have a different color from the canines, and the canines can also have a different color from the molars. The color function can be integrated in a very early treatment step in order to combine with the shape function to produce an attractive appearance. Here, the color appearance can be gradually brought closer to the desired state to test the best presentation. Thus, color - correction can be carried out simply and economically at an early stage when needed.

[0245] Molar region function 250 / 260 / 270

[0246] Different from traditional alignment - treatment, the proposed multi - functional treatment can include a set of important functions that can be applied especially to the molar region but can affect the entire occlusion mechanism. For example, three complementary functions can be distinguished. First is the raising of the occlusal surface itself (height function 250), i.e., constructing a certain thickness on the occlusal surface of the molars. The premolars and canines can also be affected by the raising. In the region of the front teeth, this can also be a clearly visible lengthening and enlargement.

[0247] However, biomechanically and physiologically, the height function 250, i.e., the raising of the molars by supports integrated into the splint - like device 10 composed of the maxillary part 11 and the mandibular part 12, is already very important. The supports can be implemented with different thicknesses in the upper - right, lower - right, upper - left, and lower - left, such that there is asymmetry. In the sagittal plane and the frontal plane, by installing structures of different heights in the molar region, a new optimized position of the occlusion plane can be adjusted. Where applicable, the different thicknesses or heights of the supports can not be specifically manufactured by deep - drawing. However, 3D printing and 3D milling etc. can be used as manufacturing methods.

[0248] In contrast, the sliding surface (sliding function 260) is implemented, replacing the natural protrusions and fissures in the molar region. Here, the upper and lower sliding surfaces can correspond to each other, i.e., for example, have complementary shapes to each other. Here, the upper surface can be designed differently from the lower surface. For example, the lower surface is almost flat and smooth, while the upper surface is a cylindrical ball with the cylinder axis from right to left. Different implementations can allow different sliding movements and rolling movements of the mandible relative to the maxilla in detail. This is called the sliding function 260. The sliding function 260 may at least need to cover the protrusions and fissures of the teeth located below it. The sliding surface can also be mounted on a structure of any thickness. The sliding surface can be flat, or formed into a spherical, cylindrical, hyperbolic, convex, concave or other shaped.

[0249] In contrast, the implementation of the lateral migration function (lateral function, ramp function 270) can act in the anterior-posterior (front-back) and left-right lateral directions in the lateral plane. In the simplest case, this can be a ramp or inclined plane that makes continued migration difficult or blocked starting from a specific area. For example, ramps of the same extension on the left and right sides can be used to push the mandible forward immediately after the mouth is closed. When the orientation of the ramp in space changes, the opposite effect occurs and the mandible can be pushed backward. Using ramps of opposite extensions on the right and left sides, the mandible can be twisted or pivotally rotated relative to the maxilla. Using partially anterior-posterior extended ramps or inclined planes, the mandible can be migrated from right to left or from left to right. All of these may require a structure with a certain minimum height in the molar region. However, the structure does not necessarily have to include a ramp or inclined plane.

[0250] 5) Functional type: height function 250 (height): At least one device for 10.n can have a height structure in at least one molar region, and the height structure can at least cover the fissures (tooth pits, tooth protrusions). In the four quadrants I to IV of the full set of teeth, the height structures can be different in height, and / or the height structures can be different in inclination. Preferably, the height structure can be increased by 0.5 mm (millimeters) to 6 mm. Particularly preferably, the height structure is increased by 1 mm to 4 mm. Here, the increase can indicate the total layer thickness beyond the occlusal surface, for example, the total layer thickness at the center of the occlusal surface. The structure can have a protrusion-like structure at the contact surface and / or does not have to be a flat ramp and / or inclined plane or a smooth sliding surface.

[0251] 6) Functional type: Sliding function 260 (sliding): The device may have a slidable surface element in at least the molar region for 10.n, and this surface element preferably has a low surface roughness. The orientation of the sliding surface may be parallel to the previous occlusal plane, or may be arranged inclined to the previous occlusal plane, in particular to set a new occlusal plane as the sliding plane. The sliding surfaces in the four quadrants I to IV may be formed complementarily up and down or differently. The effect of the sliding surface may be that as long as there are no, for example, ramps, stop forces or blocking forces, the contact force may be largely perpendicular to the sliding surface.

[0252] 7) Functional type: Lateral function or ramp function 270 (ramp): At least one device pair 10.n of the device may have a structure with a lateral force acting in at least one molar region, such as a ramp or a local inclined plane. The ramp may be oriented such that it generates a reaction force non-orthogonal to the occlusal plane during the contact between the maxillary device 11 and the mandibular device 12 when closing the mouth. Depending on the orientation of the ramp or inclined plane with the same action, the lateral force may be generated backward, forward, left or right. When combining ramps with different actions on the right and left sides, a torque around the main vertical axis may be generated. By using projections that generate a clear preferred direction corresponding to the opposite sides of the upper and lower jaws so as to adjust the lateral force acting, a shaped occlusal plane can be formed, and a special form integrating local inclined planes can be generated. Within certain mechanical limits, a combination of the sliding function 260 and the lateral function 270 or ramp function 270 is feasible, for example, in one embodiment, the sliding surface of the sliding function 260 can slide almost unobstructedly to a certain stop range on the inclined plane of the ramp function 270 and then start to almost prevent further movement or make it difficult. There may also be height structures of the height function 250 here to realize the sliding surface of the sliding function 260 and the ramp of the ramp function 270.

[0253] Additional anchoring function 280 / 290

[0254] In most cases, the maxillary splint 11 and the mandibular splint 12 of the device or device pair 10 of the kit 100 may be held respectively by retainers in the upper dental arch or the lower dental arch.

[0255] 8) Functional type Implant function 280 (implant): At least one device pair 10.n may also have at least one element for fastening at the implant, i.e., for example, in the case where a person already has such an implant or such an implant is implanted within the scope of a treatment plan. However, biomechanically and physiologically, most implants should not be overloaded at the implant-bone interface, as this would weaken the anchoring in the jaw and particularly interfere with the anchoring of the bone. For example, by integrating specific implant elements or implant function 280, the anchoring of an upper jaw splint or a lower jaw splint can be carried out within the scope of the provided method at the implant, and the implant element or implant function fastens the device at the jaw without transmitting, for example, interfering forces and moments. Forces acting axially in the direction of the implant axis are particularly allowed.

[0256] 9) Functional type Support function 290 (support): At least one device pair 10.n may also have at least one element that supports on a bone body structure covered with soft tissue, particularly the gingiva. Support on the gingiva can be beneficial when teeth or implants do not need to be fully anchored and when, for example, a plurality of teeth should be moved to a higher position from the jawbone. For example, the support function 290 is required when there are no implants and / or when molars are missing or the area of molars is missing.

[0257] Multi-functional or multi-functional embodiments

[0258] The device 10 of the kit 100 may include an upper jaw splint and a lower jaw splint, and the upper jaw splint and the lower jaw splint may be equipped with a plurality of functions, such as functions selected from a multi-functional group of functions. The multi-functional group of functions may include function elements designed correspondingly in at least two, preferably some or a plurality of the devices of the kit 100.

[0259] During the stage or period of multi-functional treatment by using the device or device pair 10 in the kit 100, the device may use at least two or at least three or at least four different functions from the following functional types, preferably at least five functional types, particularly preferably at least six functional types, wherein the alignment function 210 and the aesthetic shape function 230 may particularly preferably occur at least partially during the operation of the kit:

[0260] -1) Functional type Alignment function 210 (alignment),

[0261] -2) Functional type Displacement function 220 (displacement),

[0262] -3) Functional type Shape function 230 (shape),

[0263] -4) Functional type Color function 240 (color),

[0264] -5) Functional type Height function 250 (height),

[0265] -6) Functional type: Sliding function 260 (Sliding),

[0266] -7) Functional type: Ramp function 270 (Ramp),

[0267] -8) Functional type: Implant function 280 (Implant), and

[0268] -9) Functional type: Support function 290 (Support).

[0269] Although according to the prior art, the alignment splint is a combination of functions 201 and 220, the proposed type of fully integrated multi-functional device includes the selection of functions 210 to 290, especially also including the selection of shape functions.

[0270] The most visibly obvious objects can be that these devices not only include the alignment function 210, but also at least the shape function 220, and preferably also the color function 240 as an aesthetically important function. Since the shape function 230 can largely visually cover the alignment function 210, the alignment can be performed behind the scenes, making it almost invisible to the viewer of person P wearing these devices in sequence. Additional technical effects can also be added.

[0271] Multi-functional method

[0272] The proposed method can generate and / or use a kit 100 consisting of multi-functional devices 10.1 to 10.x, for example, according to a multi-functional or multi-dimensional treatment plan BP. The "phases" of multi-functionality can not only include the alignment of individual teeth, but also other dimensions of multi-functional additional functions for each tooth or tooth area. For the sake of displayability on the graphical plane, the assignment of individual teeth to the full set of teeth is no longer shown, but rather an example of the implementation of a step sequence of fully integrated multi-functional and / or multi-dimensional steps on these multi-functional or multi-dimensional treatment dimensions 210 to 290 of the treatment is shown.

[0273] Multi-functional multi-dimensional treatment plan BP

[0274] In alignment therapy, not every tooth has to be moved. Additionally, the teeth to be moved do not have to move in all phases of the treatment plan. In the proposed multi-functional therapy, geometrically, biomechanically, and physiologically feasible sets of treatment plans BP that appear viable can be generated, but these treatment plans can be three-dimensional, where only two dimensions are shown and explained here, namely the multi-functional dimension and the numbering of the corresponding devices according to the order of device use. In the tooth alignment display, these treatment plans can be successively located on separate levels, and then it can be indicated for each tooth whether and to what extent the relevant function is activated. Due to the complexity of the effects of multi-functional devices, the treatment plan can be three-dimensional here. In a combination consisting of preferably 5 to 8 functional types, there can be 5 to 8 characteristics in each phase regarding how to handle each tooth or what form the splint should have to achieve this goal. Since there are usually several feasible ways, such as introducing the shape function 230 and the color function 240 earlier or later, for example, this variability can be utilized to determine the fastest or most economical treatment plan BP. Other selection criteria can also be adopted, such as immediately using the shape function 230 to enable person P to immediately adapt to or check the target state. If, for example, due to an accident affecting person P's tooth area or due to insufficient compliance of person P or the patient, a deviation or conflict with the treatment plan occurs unexpectedly, the treatment plan BP can be adapted. Compared with the previous narrow-band alignment therapy, the multi-functionality can provide significantly more adaptation possibilities.

[0275] In a particularly preferred embodiment, at least one or more of the alignment function 210, the displacement function 220 (displacement), the shape function 240 (shape), the height function 250 (height), the sliding function 260 (sliding), and the ramp function 260 (ramp) can be combined. Additionally, a feasible function is the color function 240, and if necessary, an implant function 280 and / or a support function 290 can also be added.

[0276] In the treatment plan BP, alignment can be planned first, where the alignment function 210 can be combined with the displacement function 220 (displacement) in the dental arch to, for example, achieve the displacement of teeth outward towards a further constructed dental arch, such as in the lower jaw UK, 4 and / or in the upper jaw OK, 5. The enlargement of one or more dental arches can be advantageous to, for example, create space for appropriate tooth displacement and / or subsequent tooth structures.

[0277] If a collision between the upper middle teeth and the lower middle teeth is detected in the step-by-step treatment plan BP, the occlusal surface height can be increased by the structure of the height function 250. Preferably, the height function 250 can be used in the start phase of the treatment plan BP, where the layer thickness of the height function elements can be gradually increased from one device to another. Compared with the original starting tooth alignment, the first device can have a relatively large jump of the height function elements of the height function 250, for example, more than 2 mm or even more than 3 mm.

[0278] At the same time, the sliding function 260 can preferably be activated because otherwise, for example, biomechanical and muscular as well as neurophysiological load conditions may occur, especially in the jaw joints. To enable the desired position correction of the lower jaw UK, 4, a ramp function can preferably be integrated in a subsequent phase or period of the multi-functional treatment plan BP or the ramp function can be integrated into the device. But this can also be done in advance. If the patient or person P wears an implant, the implant anchoring element 280 can also be integrated, for example, from the very beginning. In the case of a person who supports missing important teeth, the support function 290 can be integrated as a support into the device of the kit 100 or into a part of the device as needed.

[0279] Multi-layer device

[0280] Due to the use of the shape function 230, requirements can be placed on the material of the visible area of the splint (device). Particularly preferably, a very attractive and natural-looking material is used, such as multi-layer PMMA (polymethyl methacrylate) or other suitable materials. However, in terms of distinguishing between multi-layer materials or single-layer materials, this material can be regarded as a material layer, i.e., a homogeneous material. The seemingly attractive polymer material may not be entirely suitable for manufacturing the entire splint or the entire device. There may be materials that are more suitable for forming the recesses that should accommodate the teeth and, where applicable, migrate the teeth.

[0281] Therefore, in a preferred embodiment, the lower jaw splint and / or the upper jaw splint can be composed of at least two different materials. The externally visible layer can be made of a material that looks as attractive as possible or feels good in the mouth. This material can at the same time be a material that can sufficiently resist the occlusal action of the occlusal movement, for example, the occlusal action of this occlusal movement can also occur when the person P is not eating. The inner layer or the inner region can be provided with surface elements or can be entirely composed of a material that enhances adhesion (see, for example Figure 14 )

[0282] In another embodiment, the occlusal surface can be made of a relatively wear-resistant material, while other areas of the splint are made of another material with lower wear resistance. Therefore, the splint (device) can remain functional and / or healthier for a longer time.

[0283] The inner layer or inner region (see Figure 14 , reference numeral 18) can be completely or partially surrounded by a visually appealing outer layer. Depending on the relative position of the tooth receiving area of the splint with respect to the shape function 230 designed to be an appealing visible dental veneer, the inner layer or inner region of the splint can locally have different thicknesses.

[0284] In a preferred embodiment, with respect to the advanced splints of the kit 100, at least for at least 2, at least 3, or at least 4 successively following groups of devices 10, only the inner layer 18 or inner region having the tooth receiving area changes, while the outer layer having the dental veneer shape 19 remains unchanged. For example, so that person P can wear and feel the target tooth alignment, reduce the number of adaptations when changing devices, or achieve other technical effects.

[0285] In the proposed device, in a particular embodiment, the inner layer 18 or inner region of the maxillary splint 11 and / or the mandibular splint 12 is manufactured separately and inserted into the outer layer of the splint (see Figure 14 ). As long as the shape function 230 remains unchanged on multiple devices 10 and only the tooth receiving area for the teeth to be migrated needs to be migrated, in a particular embodiment, the tooth receiving area can be made of a second material and inserted into a splint having a dental veneer shape 19 composed of shaped bodies to form the entire splint for the mandible or maxilla. Thus, the total cost of manufacturing the splint or device can be significantly reduced because only the internal components need to be replaced, while the dental veneer and, where applicable, other outer regions of the device can be used multiple times with different internal components from each other.

[0286] End of treatment

[0287] The last device 10.x of the kit consisting of x devices constitutes the end of the alignment treatment, resulting in a new position of the real teeth. Since, for example, the occlusion plane can be corrected optionally simultaneously in the initial period, the biomechanics can also be optimized at this time, provided of course that when the teeth are adapted both functionally and aesthetically to the target geometry by restorative measures on the one hand and on the other hand. The required installation space can be available at this time because, for example, the occlusion is increased separately by occlusal plane elevation and / or because space is created by arch enlargement. The final dental medical body 300 after splint treatment with the kit 100 consisting of devices 10.1 to 10.x can be different from the last splint because the teeth are then, for example, individually brought into this target geometry by means of so-called "tabletops", bridge structures, inlays, veneers, etc. Here, the final geometric state of the restored teeth can be the same as or very similar to the shape and arrangement of the teeth in the full set of teeth already replicated by the sequence of splints 10 and finally by the last splint 10.x.

[0288] Functional and technical effects

[0289] The following functional and technical effects can be produced:

[0290] - Compared with a device having only the basic alignment function 210, the mechanical stability of the device can be significantly higher by installing components providing additional functions.

[0291] - In particular, the height structure of the height function 250 can lead to an improvement in the mechanical stability of the area where the molars are arranged or should be rearranged (i.e., the molar area of the device).

[0292] - In particular, at least one veneer or a plurality of veneers included in the shape function 230 can significantly improve the mechanical stability of the device in the anterior tooth area of one or more devices.

[0293] - It can cause an early mechanical action on the sensitive areas of the inner side of the upper lip and / or the inner side of the lower lip, thereby stimulating the muscles of the occlusion mechanism and initiating neuromuscular processes.

[0294] The biomechanical and / or cranial optimization of the position of the occlusion plane can be an important advantage related to biomechanics and health. This can be achieved by reducing the load on the teeth and by a physiologically better load pattern in the jaw joint. In terms of neuromuscular, the advantage can lie in the better stretching of soft tissues by the larger volume (Volumina) of the veneers and structures. This can have a positive impact on biomechanics and, if applicable, produce additional aesthetic and psychological advantages.

[0295] The increased stability can be used to introduce stronger forces into the teeth. By the increased stability, the risk of breakage of the device, for example, when inserting the device into the mouth, when removing the device from the mouth of person P, or when dropping the device, can be reduced.

[0296] Additional functional effects

[0297] In addition to numerous functional and technical effects, there can also be other functional effects. An important and popular advantage among patients is that the patient or person P can very quickly or early obtain the feeling of the target tooth alignment and / or obtain a very aesthetically appealing appearance of the full set of teeth or obtain a replica of the target alignment of the full set of teeth, even though the alignment function 210 and the displacement function 220 as part of the kit 100 can still cause further tooth migration behind the scenes.

[0298] In terms of customer satisfaction, the advantage can be that the patient or person P can see what the result looks like from an external visual observation and / or feel what the result will be like even during a treatment period lasting several months.

[0299] Psychological and / or psychosomatic advantages or effects can in particular be caused by a higher bite and larger veneers. Larger teeth, rather than teeth that have been ground down and become too short, can represent more youth and more strength. The patient will feel younger and, in most cases, also physically significantly more comfortable. This can significantly increase the patient's willingness to be treated and can lead to the device being worn very willingly and as continuously as possible, which is very important for treatment success.

[0300] In an intelligent and interdisciplinary treatment plan (see Figure 3 and Figure 4 ), further advantages are clearly positive. Through the interdisciplinary combined mode of action of the kit 100 of the device, treatment goals can be achieved in terms of function and restoration without endangering biomechanical processes and the cranial orientation of the bite plane as was the case with previously used traditional methods and devices.

[0301] Specifically, the following biomechanical, muscular and neurophysiological advantages can exist in the cranial region (i.e., the bony skull). The biomechanics of the skull and the neurophysiology of the cranial muscles can make the position of the bite plane favorable in the optimal state of the skull. The optimal state of the skull can be approached as closely as possible. Here, migrations and relaxations can occur in the cranial region, especially in the jaw joint region. These can have an impact on anatomical changes over the course of several months, which can exceed one millimeter. Such an order of magnitude can be considered significant in the dental field because patients perceive an inaccuracy of 0.1 millimeter as disturbing. Even better is to optimize the bite plane of the skull during the alignment treatment because otherwise, i.e., if the bite plane is corrected subsequently, many objects in the full set of teeth will change again. Therefore, in the kit 100 of the proposed devices 10.1…10.x, in at least some of the devices, preferably in the early maxillary splint OK, 5 and the mandibular splint UK, 4, elements for cranial optimization can be advantageously integrated. Elements for cranial or cranial optimization can be, for example, a higher sliding splint area of the sliding function 260 or a higher ramp of the ramp function 270. Put simply, the optimization can relate to the position and / or orientation of the morphological jaw joint axis, even if the jaw joint is not a hinge joint (Scharniergelenk) in the strict sense.

[0302] To adjust an optimized occlusal plane for cranial anatomy and geometry, the multifunctional treatment plan BP can use a combination consisting of the height function 250 and / or the sliding function 260 and / or the ramp function 270. In particular, wear on one side after unfavourable tooth extraction at an early age may lead to a significant inclination of the occlusal plane. To be able to reorient the occlusal plane, individual matching patterns can be designed from the functions 210 to 290 so as to perform appropriate cranial optimization as reasonably as possible. The actual final period of one or more alignment functions 210 and displacement functions 220 is only feasible after adjusting the occlusal plane according to cranial analysis. In combination with the adjustment of the occlusal plane, disorders of the jaw joints can be treated. These disorders can gradually disappear slowly during the optimal adjustment of the occlusal plane. However, to achieve faster progress in jaw joint treatment, the multifunctional treatment can use a combination consisting of the height function 250 and the sliding function 260. Thereby, the functional effect of the orthosis can be fully integrated into the device and the treatment plan. Therefore, pre-treatment or follow-up treatment using an orthosis may no longer be required after multifunctional treatment.

[0303] Advantages and effects of the multifunctional technique, such as those related to aesthetics.

[0304] Aesthetic advantages can be achieved for the first time in combination with technical effects, additional biomechanical effects and / or the above-mentioned physiological advantages. From the patient's perspective, the advantages can lie in the aesthetic state of the full set of teeth being restored at a very early stage, preferably from the beginning, thus resulting in a significant external improvement, and no pain occurring in the jaw joint area during and after treatment.

[0305] The alignment function 210 and the displacement function 220 can be planned such that a predictable enlargement of the dental arch can be achieved, and in particular, at the end of treatment, the optimal position of the teeth in the enlarged dental arch can be achieved. Additionally or alternatively, individually designed dental veneers of the shaping function 230 can be integrated. The individually designed dental veneers can be larger in the first splint as part of the device 10 and follow or correspond to the desired larger dental arch.

[0306] Therefore, the multifunctional treatment plan can bring an early replica of the beautiful reconstruction of the optimized tooth shape for the observer by using dental veneers or tooth replicas. This can be an obvious external feature of the patient or person P undergoing multifunctional treatment. In contrast, a patient undergoing only traditional alignment treatment does not initially improve the aesthetics of the full set of teeth.

[0307] The multifunctional treatment can, for the first time, very quickly and temporarily reconstruct the strongly worn and overly short teeth of an older full dentition, resulting in a very rapid and very obvious improvement in terms of aesthetics and / or haptics. Here, the older visual and haptic impressions of the worn full dentition can be converted, early or quickly, into an attractive and healthy impression of a younger full dentition by means of a dental replica or veneer.

[0308] The multifunctional treatment can also have further advantages: In the case of an optional combination with a color function 240, the veneers of the splint can be aesthetically improved step by step at reasonable cost. Depending on the expectations of the patient or person P, the splint can be designed optically in the previously visible veneer so that it pre-emptively acquires the subsequently desired tooth color. Thus, in the treatment plan BP, optimized coloring can in principle be carried out early. Excellent additive manufacturing techniques can bring additional advantages here. However, materials with very excellent properties, such as polymer multilayer materials, can also be used. These materials can enable a mechanically very stable device. In addition, these materials can also produce a very good aesthetic impression, visually or also haptically, for example in machining. Color correction can be carried out early to avoid additional costs and additional effort in the final medical body.

[0309] Function combinations changed via the step sequence of the kit

[0310] The proposed device 10 can consist of an upper jaw splint 11 and a lower jaw splint 12 respectively, and is characterized in that the device 10 can have a comprehensive combination of different functional types. In principle, the above functional types are available for selection. The functions of the above functional types can be used on the teeth or tooth regions when needed and when appropriate. However, not all and / or not all of the functions of the above functional types have to be used simultaneously. This means that depending on the need and suitability, functions can also be omitted. The multifunctional treatment plan BP can determine which functions are activated for which teeth and when and which functions are not activated. The multifunctional treatment plan BP can, for example, consider up to eight or more functions at this time, and the treatment modes can be diversified accordingly. Therefore, not all functions of the multifunctional treatment plan BP can always be extracted from a single device.

[0311] Figure 1 A roughly schematic and very simplified illustration of the kit 100 of the device 10 is shown, where the device 10 consists of an upper jaw splint 11 and a lower jaw splint 12 respectively. The kit 100 of the device 10 includes x devices 10.1 to 10.x, where x is a natural number, for example 10 to 50.

[0312] The devices of the kit can include a combination consisting of functions (in the embodiments shown here, at least a) alignment function 210, b) displacement function 220, and c) shaping function 230). The functions can occur in a device in a combined manner, or occur successively in individual numbers of devices at different times in the kit 100, or occur only in a single device.

[0313] The alignment function 210 can be shown in the contact element 13, which can be adapted or configured to transfer force and torque to a tooth or tooth root in order to better position the teeth side by side. Optionally, the tooth can be provided with an attachment.

[0314] The displacement function 220 can be shown in a device that is adapted or configured to follow a large-scale plan to migrate a tooth, preferably to follow a large-scale plan to migrate a tooth in terms of further enlarging the dental arch.

[0315] The shaping function 230 can be shown at the device 10, where at least some of the veneers have an independent shape that is different from the shape of the real medical (where applicable) tooth or tooth root, for example:

[0316] - where the shape is reconstructed, and / or

[0317] - where the veneer covering the actual or underlying tooth is larger or has a greater volume compared to the underlying tooth, and / or

[0318] - where the veneer is longer, and / or

[0319] - where the veneer has a more suitable shape different from that of the tooth.

[0320] As Figure 1 shown, the view visible from the outside can be generated or composed of the shape of the visible veneers. The feature of the proposed technique can be that on the device or a part of the device of the kit 100, the shape of the device 10 (as long as it is visible from the outside) changes little or not at all, while changes occur in the covering area, especially at the covered tooth.

[0321] When the device is outside the mouth of the person P, a professional can identify the differences between the devices 10 at the faintly recognizable starting points (Ansatzpunkten) of the alignment elements 13 during the operation of the kit. However, the changes in the person's full set of teeth either occur in the area covered by one or more veneers at the actual teeth of the full set of teeth, or occur in the molar area that cannot be directly seen from the outside.

[0322] The treatment plan can generally include x stages, where x is the natural number as described above. Kit 100 can include x devices, one for the upper jaw OK, 5 and one for the lower jaw UK, 4, i.e., a pair. The force application points of the interaction forces between the devices and the teeth can vary from device to device. Thus, the teeth can be gradually migrated. In Figure 1 the force-functional element 13 of the covering mount is systematically shown.

[0323] Particularly meaningful can be that, in an integrated technology, the devices 10 have been optimized in terms of shape and optionally color. For example, during a quick observation, the differences between the devices 10 of kit 100 cannot be seen from the external geometry and / or color. The differences between successive devices 10 can particularly lie in the front teeth covered by one or more veneers, especially in the exact position of the recesses of the tooth intrusion, i.e., for example, in the force-functional element 13 where the force can be applied to the tooth and in the free space provided for the tooth for the reaction movement to the force F.

[0324] The movement of the teeth can follow the treatment plan BP behind the scenes and cannot be directly recognized from the outside. The last device 10 forms the end of the multi-functional alignment treatment. Then, the full set of teeth with the teeth and tooth roots in the new position can be equipped with the dental final medical body 300. The tactile and visual impressions will only change slightly when transitioning from the last device to the final medical body. In the final medical body 300, the teeth can be blocked as little as possible, because otherwise the osseointegration may be affected.

[0325] The devices or device pairs 10 of kit 100 can be worn successively by person P (for example, see Figure 8 and Figure 10 ). All or some of the device pairs can include veneers. The veneers are marked with N.I.1.2, N.II.1.2, N.III.1.2, N.IV.1.2, N.I.1.2, etc. according to their positions. The identification follows the tooth position identification used by dentists and orthodontists, i.e., using four quadrants or sectors I, II, III, and IV, and the teeth in the quadrants are numbered successively from 1 to n from front to back with respect to the reference system of person P. As observed by the observer, quadrant I is in the upper left, quadrant II is in the upper right, quadrant III is in the lower right, and quadrant IV is in the lower left. Thus, the order of the quadrants can be shown in a clockwise or clockwise direction. The naming of the veneers can be as follows:

[0326] - The first letter is N (replica, veneer), in contrast to which the tooth is Z or the recess is A,

[0327] - The Roman numeral in the second place represents the quadrant, as described above,

[0328] - The number in the third place represents the position within the quadrant, and

[0329] - The digit in the fourth place represents the number of the relevant device in the order of the devices 10 of the kit 100.

[0330] For example, the dental veneers N.I.1.2, N.II.1.2, N.III.1.2, N.IV.1.2 are located in the first or front positions of the first quadrant I, the second quadrant II, the third quadrant III, and the fourth quadrant IV respectively in this order. As Figure 1 shown, the positions of the said veneers are in the second device, which are respectively represented by the last digit. In the state of use of the device 10.2, the corresponding tooth positions of the corresponding front teeth behind the dental veneers are Z.I.1.2, Z.II.1.2, Z.III.1.2, and Z.IV.1.1. The second tooth from the upper left as observed by the observer has the mark Z.I.2.2, that is, it is in the second position in the quadrant II in the device 10.2. Therefore, the relevant dental veneer or tooth replica is marked with N.I.2.2.

[0331] The number n can represent the order or the device or device pair 10 in the middle part of the kit 100. For example, see the dental veneer N.I.2.n, which is located in the same position as the dental veneer N.I.1.2, and its outer surface, especially its front surface, can be designed to be the same as that of the dental veneer N.I.1.2. The three dots indicate that at least one additional device pair, usually multiple device pairs, of the kit 100 can be located between the third device pair 10.3 and the device pair 10.n.

[0332] The number x can represent the order or the last device or device pair 10.x of the kit. For example, see the dental veneer N.I.1.x, which can correspond to the dental veneers N.I.1.2, N.I.1.n, that is, the same outer shape and / or can be arranged in the same position relative to the device, especially the upper dental arch of the upper jaw device 11. The three dots again indicate that at least one additional device pair, usually multiple device pairs, of the kit 100 can be located between the device pair 10.n and the device pair 10.x.

[0333] The device part located on the right "re" in the device as observed by the observer (dentist, technician, orthodontist) is on the left side relative to the person wearing the device (device pair). This is indicated by "li(P)" in the figure. Similarly, the device part located on the left "li" in the device as observed by the observer is on the right side relative to the person wearing the device (device pair 10.1, etc.). This is indicated by "re(P)" in the figure.

[0334] Therefore, Figure 1It is clearly shown that the front regions of devices 10.1 to 10.x can remain unchanged, while the alignment function 210 of the devices changes. Additionally or alternatively, the front regions of devices 10.1 to 10.x can remain unchanged, while the structures in the molar regions change, for example, structures with a height function 250 and / or a sliding function 260 and / or a ramp function 270 change. For example, referring to the molar region in the first quadrant I, this molar region can be different in the first device 10.1 than in the second device 10.2, and can be different in the last device 10.x than in the intermediate device 10.n, see arrows P1 and P2.

[0335] Figure 2 A comparison - alignment - treatment plan BP2 for x alignment splints S.1 to S.x is 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 tooth groups into the basic dental arch. The displacement function 220 is used, for example, for large - scale migration or alteration of the dental arch, for example, in expanding the dental arch in order to create more space. In many cases, the displacement function 220 can be utilized for such expansion so that the alignment of existing teeth can be carried out first, that is, in order to create the required space. Since the alignment splint can also squeeze the teeth from the inside, thereby causing the tooth to tilt outwards, there can be a certain degree of overlap between the alignment function 210 and the displacement function 220. Generally, the so - called attachments can correspond to the alignment elements at the tooth - receiving recesses in the splint, but the attachments are not mounted on the splint, but on the corresponding teeth. The tooth - receiving regions in the splint generally allow a certain degree of mobility in the desired direction of tooth migration. Therefore, by separately combining the alignment function 210 with the displacement function 220, success can be achieved within certain limits. The sequence of the splints can guide the teeth to a new condition, especially those teeth that are initially very different from the target state can be displaced and / or twisted. After the alignment treatment with the last splint 10.x, the teeth are in a new formation, but they still look the same as before. Only until this point can the teeth be further treated medically in the final treatment 300 using aesthetic, dental - technical, and dental - technological means, such as through veneers and / or crowns (Kronen) and / or facings. In this case, only at this time can the appearance of the teeth change, but it can change significantly at this time. Especially in the case of adult patients or persons with full - scale tooth wear and malposition, this type of alignment treatment may have obvious weaknesses and very limited effects.

[0336] In a comparative example, the treatment plan BP2 may include only two sub-treatment plans BP2a and BP2b, which indicates that fewer functions are used within the comparative kit S1-x consisting of the device or pair of devices. In particular, the comparative kit S1-x may not include the shaping function 230, i.e., veneers. In contrast, the device or pair of devices S1, …, S.n, … S.x of the comparative kit S1-x may be made of a transparent or at least translucent material.

[0337] Figure 3 Schematically shown is the proposed multi-functional treatment plan BP3. Kit 100 includes x number of devices 10. Kit 100 is built on the initial state 200 of the full set of teeth. The first device of kit 100 is device 10.1 and the last device is device 10.x. In the multi-functional treatment step of kit 100, state 10.x is reached using device 10.x, i.e., the end of the treatment is reached using a splint or device. Then the final medical treatment 300 can be implemented.

[0338] Through the multi-functional combination of these functional elements combined in a fully integrated manner in kit 100 of devices 10, a multi-disciplinary effect is produced that cannot be achieved with simple alignment splints, such as the comparative-alignment splints S.1 to S.x according to Figure 2 Starting from the state reached by device 10, the final medical body 300 can then be implemented using a tabletop, veneer, etc., i.e., after removing the last splint 10.x.

[0339] In the case where the color function 240 is activated, the color selection can be pre-tested during the multi-functional treatment. In the illustrated embodiment, the alignment function 210 can extend over most of kit 100 as the teeth migrate relative to their adjacent teeth, or extend over the entire kit 100 as shown. Then, devices 10.1 to 10.x continuously carry suitable alignment elements or have a suitable position or shape for the teeth at the selected recesses to migrate the selected teeth by contact force and torsional or tilting moments combined with the required degrees of freedom of movement.

[0340] In the illustrated embodiment, the multi-functional diversity includes an alignment function 210, a displacement function 220, a shaping function 230, a color function 240, a height function 250, a sliding function 260, a ramp function 270, an implant function 280, and a support function 290.

[0341] The arrows along the function column indicate that the functions can be optionally activated, but do not have to be continuously activated in all devices. Generally (not shown here), some of the functions in the current kit 100 may not be activated because the female or male patient (person P) does not require the function. Particularly rarely, the implant function 280 may only be activated in the presence of an implant.

[0342] It can be clearly seen that, for example, in the case of using dental veneers or tooth replicas, the shape function 230 can be used from the very beginning, that is, it can be used in the first device 10.1 and / or in all devices 10.1 to 10.x. This can be relatively unproblematic in some treatment cases. In other cases, this can be supported or achieved by other suitable functions of functions 210, 202, 240 to 290.

[0343] The use of dental veneers can have a technical association with the color function 240, such that transparent materials without staining and / or without white or other opaque coatings may not be suitable for providing a visual covering function. However, if the stabilizing function and / or the tactile function of the dental veneer is sufficient or provides other sufficient advantages, then transparent materials can be used, for example.

[0344] The color function 240 can be optionally used from the very beginning, that is, in the first device 10.1 and / or in all devices 10.1 to 10.x. The color function 240 can be optionally varied within the kit to find a suitable hue or a suitable color gradient. The color function 240 can achieve colors different from transparent and / or translucent materials. Within this understanding, white is also regarded as a color because white can also satisfy the function of covering or veneering.

[0345] The arrow in the shifting function 220 that starts later, for example, indicates that alignment will be carried out first before the shifting function 220 starts in the device 10.f.

[0346] The initially activated sliding function 260, for example, indicates that in the molars, the first device can carry a sliding device, while the later ones do not. In contrast, in the molar region, the height function 250 (height) is continuously present in the example because, for example, the teeth are worn and a previously too deep occlusion must be corrected. Generally, the functional elements implemented in the device 10 can be different between the devices following one another. The device 10.n not only differs from the subsequent device 10.n + 1 in the geometry of the force transmission element 13, but can also include different combinations of functional elements and functional types, but the exterior of the dental veneer can remain the same or unchanged.

[0347] An important feature is that the shape function 230 can also be used very early as a mechanical stabilizing function and also, where applicable, as, for example, a biomechanical action function or as an aesthetic function, while in the comparison - alignment - treatment according to Figure 2 no dental veneers are used, so that the shape and / or position of the recess does not change behind or in the dental veneer either, relative to the dental veneer with no change in the front part. The shape change is proposed by the design of the dental veneer related to the device 10, rather than by simple material deformation around the receiving part or recess for accommodating the tooth.

[0348] In the compact multi-functional illustration of the selected treatment plan BP3 here, it should be noted that each column for each function can be related to the pattern of usually up to 32 teeth of the full set of teeth. Thus, the view shown is the sum of the teeth of the full set of teeth. Activation of a function means activation in at least one tooth or at least one group of teeth in the relevant device. In addition to here Figure 3 and Figure 4 the multi-functional "phases" shown, for the complete multi-functional treatment plan BP3 or BP4, dental "phases" related to individual tooth positions (up to 32 tooth positions) are also added. This distribution of activation on individual teeth is not shown here.

[0349] Treatment plan BP3 can utilize the final medical body 300, i.e., completed, for example, by veneers and / or crowns or table tops, preferably oriented towards the final or target tooth state, i.e., oriented in accordance with the labial shape of dental veneers N.I.1.1 etc. which are also oriented towards the final or target tooth state.

[0350] Treatment plan BP3 includes, for example, nine sub-treatment plans BP3a to BP3i, which sequentially correspond to the above functions 210 to 290.

[0351] Figure 4 A treatment plan BP4 for special but also frequently occurring situations is shown, which does not have the implant function 280 and the support function 290, but instead has a significant shape function 230 (i.e., the shape function of the anterior visible dental veneer of a splint, for example) and / or a color function 240 (i.e., the color design of the anterior visible dental veneer of a splint, especially different from a transparent and / or translucent color design).

[0352] In this case, the maxillary splint 11 is located on the teeth of the maxilla OK, 5 in a directly clamping manner, and the mandibular splint 12 is located on the teeth of the mandible UK, 4 in a directly clamping manner. The step-by-step, subsequent alignment function 210 with tooth migration and orientation will end at the position for the final medical body 300 afterwards. At the same time, as needed, in the case shown, the phase of the displacement function 220 occurs in the middle area of the sequence, in which the teeth move outwards, for example. This displacement function 220 will 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 terms of shape and size in the final stage 300 (final medical body) after multi-functional treatment with the kit 100.

[0353] The step-by-step, subsequent alignment function 210 is illustrated by a plurality of arrows to illustrate with Figure 3There is an increase in the complexity of alignment. Thus, during treatment plan BP4, alignment can involve different teeth.

[0354] The shape function 230 can also be phased, as illustrated by multiple arrows, for example, so as not to move suddenly from an initial state to a final state, i.e., such that, for example, the enlargement of the dental arch does not occur visibly immediately and thus is not visibly apparent to everyone, but rather occurs in phases and thus unobtrusively for a third party and person P. Thus, the shape function 230 (veneers) does not have to be directed towards the final target tooth state from the beginning. Intermediate target tooth states can be used. Alternatively, in treatment plan BP4, in the case of using relevant dental veneers and / or dental replicas, a shape function 230 that remains unchanged or only changes slightly can also be used.

[0355] Optionally, additional functions can be added, such as the orthosis function 275, such as the 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 markings / markers / scales) or other methods. The orthosis can include an edge gap, but this is not necessary.

[0356] Figure 4 It is shown that the optional color function 240 is activated in phases by arrows so as not to move suddenly from an initial state to an optimized brighter state, for example, from a more yellow coloring to a more white or white coloring. Alternatively, in treatment plan BP4, a color function 240 that remains unchanged or remains substantially unchanged can also be used. For example, the color can only vary within the scope of manufacturing possibilities and / or manufacturing tolerances.

[0357] Also in Figure 4 as in Figure 3 the same, the height function 250 is continuously activated because the teeth are worn in the initial state 200. The order of the arrows along the function column 250 shows that structures of different heights are used continuously or successively in the molar region.

[0358] The sliding function 260 is shown in stages at the devices or device pairs 10.1 to 10.x, for example, by a sliding area in the molar region.

[0359] The ramp function 270 is additionally activated in stages, especially when the biomechanics of the jaw joint requires it, for example, in the second half of the kit 100.

[0360] The sequence shown here is only for explanatory assistance. The correct sequence for a given patient or person P can be determined based on the initial state and with the aid of the planned target state. However, in any case, even for complex malpositions and wear situations, the multi-functional treatment offers far more treatment possibilities than ever before. The target group can be patients or person P aged 30 to 80 years, i.e., the target group can be very large. Since functional advantages (especially in terms of aesthetics and / or haptics) are considered decisive, the willingness to invest can be high. Especially in patients over 50 years old, and especially in people over 60 years old, due to wear, a pure alignment treatment using only the alignment function 210 and, where applicable, also the shifting function 220 is usually not meaningful.

[0361] The treatment plan BP4 includes sub-treatment plans BP4a to BP4i, which correspond in sequence to the above-mentioned functions 210 to 290.

[0362] In Figure 4 In the method explained, additional optional functions can also be added, such as the orthosis function 275, for example the 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 markings / markers / scales) or other methods. The orthosis can include an edge gap, but this is not necessary.

[0363] Figure 5 The mandibular part 12 is shown in the above figure as part of the device or device pair 10. Figure 5 a shows the first device part 12 of the first period from the kit 100, Figure 5 b shows the second device part 12 of the second period or second sub-part from the kit 100.

[0364] Figure 5 a shows the sliding surface 15 numbered 15 in the molar region. This can be a characteristic of the combined activation of the height function 250 and the sliding function 260.

[0365] In Figure 5 b, the height function 250 is still activated, but the sliding function 260 is not activated. Instead, the ramp function 270 is activated in a small and effective bevel manner at the teeth in the molar region. This can be recognized in the contact surface 16 with a protruding design having inclined flanks and small ramps (see arrow P5). These migrate the lower jaw UK, 4 laterally forward during occlusal contact, so at the same occlusal height, it acts completely differently from the sliding function 260.

[0366] In Figure 5 a and Figure 5In b, the front teeth are veneered and covered by the dental veneers 19 associated with the lower splint 12. Thus, the migration of the actual teeth occurs in a covered manner. In the front tooth region, moreover, the aesthetically formed dental veneers 19 form the covering part. In this case, the alignment function 210 and the displacement function 220 are installed in the recesses for the teeth, fully in accordance with the requirements of the individual and the period. However, this can only be seen when the splint is taken out of the mouth. In the molar region, the structures 15 and 16 cover the teeth. However, this can only be seen from the outside, for example, when the mouth is opened wide.

[0367] Figure 6 Schematically shown are different states of the device 10, for example, extracted from the kit 100. Here, only the lower splint 12 is shown separately. To better show the molar region, the upper splint is omitted respectively.

[0368] Figure 6 a shows the starting state 50 of the teeth of the person P or the patient. Figure 6 a shows an abnormality in the tooth state, which is usually caused by classical orthodontic measures, that is, for example, after extracting two teeth in the lower jaw. Thus, the too-small dental arch in the lower jaw is not widened, for example. This promotes tooth wear. At this time, the state of the jaw joint is usually poor, and craniomandibular disorders (CMD) may often occur. Then, the jaw joint and the occlusal plane may also need treatment.

[0369] According to Figure 6 b, the first lower splint 12.1 is located on all the teeth in the starting state 50, but the first lower splint already shows the shape function 230 at the designed larger dental veneers 19, and the front teeth are located behind and / or below these dental veneers. Thus, at first glance, compared with Figure 6 a, the front teeth appear to no longer need treatment, even if the front teeth need treatment and are being treated.

[0370] Starting from the splint 12.1 in the initial state 50, there can be a period in the multi-functional treatment plan BP and a related number of devices, where raised sliding surfaces 15 are installed in the molar regions 56 / 57 on the right and / or left. The sliding surfaces can mainly be planar or part of a hyper-surface. The sliding surfaces can thus construct the sliding function 260. The degree of elevation gives the height of the height function 250. The contact surfaces in the molar region can also include the slopes and steps or different inclined surfaces of the ramp function 270.

[0371] According to the decomposition of vector forces, the contact in the ramp and / or inclined plane can cause the force component of the masticatory muscles to act on the mandible UK,4, such that a laterally or anteroposteriorly directed force component is generated. Thereby, a change in the contact force in the jaw joint can be achieved, and the mandible UK,4 can be displaced or twisted relative to the maxilla UK,5.

[0372] In a specific embodiment, the asymmetrical arrangement of the sliding surfaces 15 and the ramps 17 in the right and left molar regions can be selected such that a complex position correction consisting of translations and rotations (e.g., a total of 6 degrees of freedom) becomes possible, particularly see Figure 6 c.

[0373] An intermediate or final goal of the multifunctional treatment can be Figure 6 the state 60 shown in d with a wider dental arch and larger dental veneers 19. At the same time, for example, particularly in the molar region, the occlusal plane can be biomechanically adjusted correctly, and the malposition in the jaw joint can be corrected. All these different treatment goals can be jointly achieved in the device 10 of the kit 100, where this series of devices 10 are respectively composed of an upper jaw splint 11 and a lower jaw splint 12.

[0374] Figure 7 Roughly schematically shown, a relatively high structure 15 (as Figure 7 shown in a) can be particularly used in the molar region to firstly achieve the release of the lateral mobility of the mandible and / or secondly to constitute a sliding surface of the functional type 60 (sliding). The structure 15 can also be referred to as a thickening. The structure 15 can be completely filled with material, i.e., the structure 15 is solid. Alternatively, the structure 15 can also include cavities inside, particularly when mechanical stability is ensured. The cavities can reduce the mass of the device.

[0375] In the contact state, the lateral mobility of the teeth may be necessary in order to be able to migrate the teeth better and / or without collision by aligning the function 210 and / or by means of the displacement function 220. In contrast, if, as in the comparison - alignment according to Figure 2 a layer with a relatively uniform layer thickness is applied to the occlusal plane, neither a sliding surface is constituted nor is the release of mobility generated.

[0376] Figure 7 b shows a specific variant, where initially a thinner structure is used and the relatively high structure (as Figure 7 shown in a) introduced very quickly causes discomfort. Therefore, the height of the structure required for treatment can be gradually increased from the state according to Figure 7 b to the state according to Figure 7 a as needed. The state according to Figure 7 b can already lead to a certain degree of relief in the jaw joint.

[0377] The direction of mandibular displacement can be adjusted by an inclined plane in the detailed design of the contact surface 16 between the upper jaw OK, 5 and the lower jaw UK, 4. At the same time, the alignment function 210 and the displacement function 220 may already be implemented and applied within a narrower range.

[0378] For Figure 7 the situation shown in a, it may be necessary that the structure on the depicted side of the upper jaw OK, 5 can be implemented with less strength compared to the lower jaw UK, 4. For example, this makes sense when the occlusal plane is non-physiologically inclined and / or when migration should occur according to the cranial or skull analysis of the cranial symmetry conditions in the patient P's skull. Such complex shapes for the devices for the upper jaw OK, 5 and the lower jaw UK, 4 cannot be manufactured by deep drawing, for example. However, such complex shapes can be manufactured by means of additive manufacturing (such as 3D printing) or subtractive manufacturing (such as milling).

[0379] The structure 15 can be symmetric or asymmetric with respect to each other from left to right.

[0380] Figure 8 A cross-section through the patient P's jaws is clearly and schematically shown, where the patient is wearing a device consisting of two parts 11 and 12, which can have specific features. The device can include or incorporate an occlusal-ramp 17 in the molar region and also a sliding surface 15 in the molar region. When the lower jaw UK, 4 and its sliding surface 15 move backward along the front-rear (anterior-posterior) axis, contact occurs at the occlusal-ramp 17 in the dashed circle. This hinders the backward movement of the lower jaw UK, 4, thus preventing backward compression of the jaw joint 5, see arrow P8a.

[0381] For example, the heights of the occlusal-ramp 17 and the sliding surface 15 are adjusted such that upward compression of the jaw joint 5 is also prevented, see arrow P8b. Thereby the muscles can be stretched and the jaw joint is relaxed. If the sliding surface 15 is configured in a way that is designed to have different heights and the position and pattern of the ramp 17 are configured in a way that is designed to be asymmetric from left to right, migration of the occlusal plane will occur as long as the device is worn.

[0382] Since it is planned to install the final medical body 300 after the last device 10, this optimized position of the occlusal plane is prepared by means of a multi-functional treatment and a kit 100 consisting of devices, such that this physiologically favorable position can be achieved in the final medical body 100.

[0383] If the structural and correction functions 250, 260, 270 cannot be performed at all due to the use of a conventional alignment device (i.e., an alignment device without a high structure), then one is forced to perform the complex final medical body 300 in the old non-physiological position of the occlusal plane. Otherwise, the suddenly changed occlusal plane would burden the patient at this time. In contrast, by means of a stepwise change of the occlusal plane and / or cranial optimization, treatment effects that were previously not feasible or were only feasible in a significantly longer treatment time or with a significantly longer treatment time are achieved.

[0384] In a detailed view, Figure 8 a typical situation is schematically shown, for example, a situation that may occur as a late consequence after the extraction of four premolars in the case of orthodontic treatment. Due to the malposition, severe wear will occur, and even the normal alignment of the teeth will be lost, for example, with respect to the Spee's curve. In this case, the teeth must not only migrate by means of a tilting moment but also be affected by elongation, i.e., move up or down, so that the section protruding from the gum "elongates". This can be achieved by a corresponding relief area for the teeth in the upper jaw, which has free space for a solidly constructed upper jaw splint (not shown, see Figure 12 ) for the lower jaw device 12.

[0385] Figure 9 Shows in accordance with Figure 9 a and Figure 9 b the cross-section through the lower jaw device 12 for the lower jaw UK, 4 in two successive cases. In Figure 9 a, in particular, the incisors 51 are twisted and not optimally positioned. Although the outer contour of the device 12 remains basically 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 veneers of the device and are moved inside or behind the veneers by the alignment function 210. Here, the free space in which the teeth can stand migrates step by step from one device to another with respect to the veneers visible from the outside.

[0386] Thus, it is feasible that, when observed from the outside, the final shape and final appearance of the full set of teeth can be replicated very quickly or early, while the alignment covered by the veneer area of the device can continue. Figure 9 The molars in

[0387] Figure 9b shows the situation after the successful migration of the anterior teeth through the alignment function 210 and the successful large-scale displacement of the molars through the arch expansion displacement function 220. 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, and even less than a quarter of the offset V9a.

[0388] It can be clearly seen from the shaded contour of the splint in the cross-sectional view that the shape of the dental veneer of the splint 12 visible from the outside, especially from the front, has not changed significantly. The migration of the teeth can generally occur in a covered manner. At the same time, the required height function 250 and / or sliding function 260 and / or ramp function 270 are not shown or cannot be shown in the cross-sectional view when applicable.

[0389] Figure 10 A comparative example of an alignment splint made of, for example, a deep-drawn almost transparent thermoplastic film material is shown. A frontal section through the incisors of the lower jaw with the splint located thereon is shown. Figure 10 a shows the initial state S.1, in which the incisors 51 (i.e., the right anterior tooth Z.IV.1.1 observed from person P and the left anterior tooth Z.III.1.1 observed from person P) are too far apart from each other, where the last digit indicates the position of the corresponding tooth at the time point when the device with the same number is first placed on the tooth. It can be seen how the almost transparent covering follows the tooth contour, and for the expected migration of the shown incisors 51 towards the middle, a smaller movement free space is provided respectively, for example, see the free space FR10a. On the pressing side, there are force transmission contact areas 13 respectively. As the force transmission element 13, a working surface can be used, which can act directly on the tooth 51 or indirectly on the tooth 51 via an accessory (not shown). Figure 10 a shows the generated vector F from left to right to indicate the direction of the left-right displacement of the tooth 51, Z.IV.1.1.

[0390] Figure 10 b shows the state of the same teeth Z.IV.1.n, Z.III.1.n after continuing to migrate to the middle sagittal plane SE. The gap between the incisors 51 or the anterior teeth closes. The almost transparent splint gradually covers the teeth and follows the moving incisors 51 formed here. The characteristic of this comparison-alignment technique is the substantially same thickness of the deep-drawn film that partially covers the teeth and / or the relatively consistent imitation of the concave shape at the external shape of the device.

[0391] Figure 10a 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.III.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.

[0392] Figure 10 b also shows the occlusal region O.IV.1.n above the tooth Z.IV.1.n and the occlusal region O.III.1.n above the tooth Z.III.1.n. The tooth Z.IV.1.n is identical to the tooth Z.IV.1.1 but has a different position and / or inclination. The tooth Z.III.1.n is identical to the tooth Z.III.1.1 but has a different position and inclination.

[0393] The axis A10.1a is in Figure 10 a shows the original position of the tooth Z.IV.1.1. The axis A10.2a shows the original position of the tooth Z.III.1.1. The occlusal region O.IV.1.1 has, for example, a maximum width B10.1a. The occlusal region O.IV.1.1 has, for example, a maximum width B10.2a. Similar maximum widths can also be on the labial outer face or the lingually oriented face of the device on the wall of the recess A.IV.1.1 or A.III.1.1. The distance D10.1a (spacing) is, for example, between the occlusal regions O.IV.1.1 and O.III.1.1. The distance D10.2a is between the recesses A.IV.1.1 and A.III.1.1.

[0394] The axes A10.1a and A10.2a are also shown in Figure 10 b to illustrate the change in the position of the tooth 51. As seen by the observer, the tooth Z.IV.1.n is shifted to the right relative to Figure 10 the position of the same tooth Z.IV.1.1 in a. In contrast, as seen by the observer, the tooth Z.III.1.n is shifted to the left relative to Figure 10 the position of the same tooth Z.III.1.1 in a.

[0395] 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. Similar maximum widths can also be present on the labial or lingual oriented surfaces of the device in the regions of the recesses A.IV.1.n or A.III.1.n. The widths B10.1b and B10.2b can be constant because the device S.n is also manufactured in a deep drawing process, and the teeth 51 do not change in their width, so the tooth replicas in the die for deep drawing also do not change.

[0396] For example, the distance D10.1b (spacing) is located between the occlusal regions O.IV.1.n and O.III.1.n. The distance D10.1b is less than the distance D10.1a due to the deep drawing process depicting a smaller distance between the teeth 51. This also applies to the distances on the labial side at the walls of the recesses A.IV.1.n and A.III.1.n.

[0397] The distance D10.2b (spacing) 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, where the model (deep drawing die) expands around the regions where the free spaces FR10a, FR10b, etc. will later be located.

[0398] Figure 11 An embodiment is shown that is different from the comparative example, especially in the anterior tooth region (see Figure 10 )). The mandibular splints 12.1 and 12.n are made of or include a polymer, for example, which preferably has an aesthetically pleasing, high-quality appearance similar to dentin and enamel, i.e., for example, is also shiny, but preferably not transparent. In Figure 11 a, the anterior teeth 51 that are still too far apart from each other should be migrated so that they are closer to each other, but only to a distance that is not required for larger veneers or for the restoration of the anterior teeth during the final finishing period or the final medical body period 300. During treatment, the veneers are formed in the early stage by one or more splints 12.

[0399] In Figure 11 a, the shaped bodies (veneers, tooth replicas) of the incisors or anterior teeth 51 are already significantly larger than the partially worn teeth 51. This is because the shaped bodies or veneers of the teeth 51 are larger than according to Figure 10This is achieved by the area of splint S.1 or S.n in the comparative example extending further beyond the incisors. In the visible area, the incisors 51 are mostly or completely covered by veneers.

[0400] The splint 12.1 shows a force transmission contact area 13 between or at the concave part of the splint and the tooth 51. Thus, the tooth 51 is migrated so that the teeth 51 move closer and closer to each other, for example, see the force vector F. Here, upon close observation, the concave part for the tooth to be migrated moves relative to the veneer that forms or is included in the splint 12.1 and remains almost unchanged. In this step-by-step movement of the concave part for the tooth, the wall thickness of the splint near the tooth to be migrated changes, see the distance / spacing D11.2a and the distance / spacing D11.2b. Along the direction of continued migration, free spaces for movement are recreated respectively, and the contact area 13 is redirected respectively so as to be able to apply a moment to the tooth again in the subsequent splint.

[0401] Figure 11 Figure b shows the migrated teeth 51 with a smaller distance. Here, the veneers (such as N.IV.1.n and N.III.1.n) are larger than the tooth 51 or Z.IV.1.n and Z.III.1.n, especially larger than the non-gingival area of the tooth 51. However, the veneers or tooth replicas (such as N.IV.1.n and N.III.1.n) preferably look like teeth.

[0402] compared with Figure 10 Figure b, the distance between the teeth 51 can preferably be a bit larger because more space may be needed or required for larger veneers. The features of the proposed embodiment can be that the veneer larger than the tooth forms the frontal segment of the splint and covers the concave part inside the splint, which accommodates the tooth and provides contact force, and moves step by step along the direction in which the tooth should migrate relative to this veneer, so that the tooth migrates relative to the veneer of the splint. The features can also be that, compared with the Figure 10 comparative example, the veneer is implemented to be significantly longer, for example, in order to reproduce the original length or a length beyond it for worn teeth. Neither of these two features appears in the comparative-aligning splint.

[0403] Therefore, the free space FR11a can be much narrower than the free space FR10a, for example, because other manufacturing techniques are used, such as subtractive manufacturing techniques or additive manufacturing techniques, rather than the deep drawing process (pressure, vacuum, and / or temperature).

[0404] Figure 11 Figure a shows the generated force vector F from left to right to indicate the direction of the left-right displacement of the teeth 51, Z.IV.1.1.

[0405] Figure 11a also shows the occlusal area of veneer N.IV.1.1 above tooth Z.IV.1.1 and the occlusal area of veneer N.III.1.1 above tooth Z.IV.1.1. The occlusal area of veneer N.IV.1.1 forms an upper covering for recess A.IV.1.1 of tooth Z.IV.1.1. In contrast, the occlusal area of veneer N.III.1.1 forms a covering for recess A.III.1.1 of tooth Z.III.1.1.

[0406] Figure 11 b also shows the occlusal area of veneer N.IV.1.n above tooth Z.IV.1.n and the occlusal area of veneer N.III.1.n above tooth Z.III.1.n. Tooth Z.IV.1.n is the same as tooth Z.IV.1.1 but has a different position and / or inclination, and tooth Z.III.1.n is the same as tooth Z.III.1.1 but has a different position and inclination.

[0407] Axis A11.1a is in Figure 11 a 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 veneer N.IV.1.1 has, for example, a maximum width B11.1a. The occlusal area of veneer N.IV.1.1 has, for example, a maximum width B11.2a. Similar maximum widths can also be on the labial outer face or the lingually oriented face of the device on the wall of recess A.IV.1.1 or A.III.1.1. The distance D11.1a (spacing) is, for example, between the occlusal areas of veneers N.IV.1.1 and N.III.1.1. For example, the distance D11.2a is between recesses A.IV.1.1 and A.III.1.1.

[0408] Axes A11.1a and A11.2a are also shown in Figure 11 b to illustrate the change in the position of tooth 51. As observed by the observer, tooth Z.IV.1.n is shifted to the right relative to the position of the same tooth Z.IV.1.1 in Figure 11 a. In contrast, as observed by the observer, tooth Z.III.1.n is shifted to the left relative to the position of the same tooth Z.III.1.1 in Figure 11 a.

[0409] 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. Similar maximum widths can also be present on the labial or lingual oriented surfaces of the device 12.n in the region of the recesses A.IV.1.n or A.III.1.n. The widths B11.1b and B11.2b can be constant since the dental veneer already has the target shape or an enlarged shape.

[0410] For example, the distance D11.1b (spacing) is located between the occlusal regions of the dental veneers N.IV.1.n and N.III.1.n. The distance D11.1b is equal to the distance D11.1a since the dental 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 no longer change in the anterior region and / or occlusal region and / or lingual region. This also applies to the distances of the labial and / or lingual surfaces at the walls of the recesses A.IV.1.1, A.III.1.1, A.IV.1.n and A.III.1.n.

[0411] The distance D11.2b (spacing) between the recesses A.IV.1.n and A.III.1.n can be less than D11.2a, as described above, for example due to a more precise manufacturing method rather than a deep drawing process. The free space FR11b in the recess A.IV.1.n can be less than or equal to the corresponding free space FR11a in the recess A.IV.1.1.

[0412] Figure 11 The shown devices 12.1 and 12.n and preferably all other devices of the same kit 100 can be manufactured by subtractive manufacturing methods (such as milling) or by additive printing processes (such as 3D printing), which, compared to the deep drawing process, particularly allow for greater variations in the layer thickness of the occlusal surface and / or allow for undercuts to be manufactured, for example, in the vertical direction with respect to the teeth of the person P.

[0413] Figure 12 Cross-sectional views through the molars and front teeth are shown in two different, successive stages of treatment with the proposed splint in the example of the lower jaw UK,4.

[0414] Figure 12 a shows a splint with a high structure (such as having a sliding surface 15) in the molar region of the lower jaw (UK, not shown), which surrounds the too-low molar 56. This molar should be moved upwards. In Figure 12In a, above the molar, there is an unfilled cavity in the recess into which the molar can move. In the region of the front teeth 51, outward growth is also possible when the force is guided accordingly.

[0415] Therefore, Figure 12 b shows the subsequent state still having the sliding surface 15, in which the molar 56 has grown into the recess in the splint 12. It may be that for the front teeth 51 that also grow outward, the splint 12 has a deeper recess into which the more upward teeth and thus the larger teeth 51 above the gums can be inserted. The feature here can be that in Figure 12 during this process, tooth migration occurs while the outer contour of the device 10 or the mandibular splint 12 shown here does not change. The different wall thicknesses required for the splint 12 or the device 10 are achieved by suitable manufacturing methods (such as by precision machining of polymer materials or by 3D printing). In Figure 12 what is not shown is that during treatment, the position of the teeth can also migrate laterally, and the axes of the teeth can also be inclined, for example, elevation can be carried out simultaneously or alternately.

[0416] Compared with Figure 12 a, in Figure 12 b, the same teeth Z12a, Z12b are shifted upward, see the horizontal lines H1, H2. The outer contour of the device 12 can remain unchanged here, see the veneers N12a, N12b in the front region of the device 12 and / or the position of the sliding surface 15 in the molar region of the device 12 relative to the line H1.

[0417] Therefore, the distances D12a or D12b corresponding to the layer thickness of the veneers N12a or N12b in the front region can be reduced, where the positions of the veneers N12a or N12b relative to the horizontal lines H1, H2 remain unchanged, and / or the external shape / contour of the veneers N12a or N12b, especially in the front region, does not change or only changes slightly.

[0418] Figure 13 Two variants of the structure of the veneers 19, N13a, N13b that look the same from the outside in the front tooth region are shown. Figure 13 a shows a structure made of solid material, where the outer contour is formed by the material of the visible veneer N13a, and the inner contour of the material forms the receiving area for the tooth Z13a. As a movement stimulus, the inner surface at the recess can apply local forces and torques to the tooth Z13a.

[0419] Figure 13 b shows the same arrangement when viewed from the outside. However, when observed locally, the device consists of two materials in two regions. Figure 13The sectional view of b shows in the outer region dental veneers 19, N13b, preferably composed of an aesthetically pleasing and attractive material, in particular a non-transparent material. Compared with the tooth Z13b, a larger recess is required inside the region 19, N13b composed of this material. This larger recess is partially filled with a second material such that a suitable recess for the tooth Z13b is retained. The inner filling 18 can be softer or harder compared to the outer shell of the dental veneer 19. In a particular embodiment, the outer dental veneer region of the successive 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. Cross-sections through the lower jaw device 12 are shown respectively, however the same variants can equally apply to the upper jaw device 11.

[0420] A narrow free space F13a can be located between the tooth Z13a and the bottom of the dental veneers 19, N13a, which can also be referred to as tooth replicas. Similarly, a narrow free space F13b can be located between the tooth Z13b and the bottom of the dental veneers 18, 19, N13b (in particular the bottom of the inner material of the dental veneers 18, 19, N13b). The dental veneer 13b can also be called a tooth replica because it, together with the tooth Z13b, replicates the target tooth state of the tooth Z13b.

[0421] Figure 14 Three alternative steps in a kit 100 of devices or device pairs 10 are shown, in particular the lower jaw devices 12.1, 12.n and 12.x, and in particular cross-sections through the incisors Z14a, Z14b and Z14c in three successive steps of a migration that can be called a displacement function 220. The purpose of such a migration is, for example, to enlarge the dental arch by further pushing the teeth outwards. Since the teeth with roots are firmly located in the jawbone, upon closer inspection, the displacement can be an inclination of the teeth around a low inclination axis, while at the same time being an adaptation of the dental veneer in its dimensions (extension) and / or orientation. At this point it is proposed that in the displacement function 220, not only the teeth are inclined, but the dental veneer is displaced and adapted in size. The recess for the actual tooth 51 can be changed in terms of inclination by significantly applying a force above the inclination axis. With the placement of the splint, the replicas N14a, N14b, N14c of the subsequently restored tooth 51 are displaced, although the actual tooth 51 is inclined in the covered area. Compared to a pure directly visible outward inclination of the teeth, the displacement of the replicas N14a, N14b, N14c and the corresponding restoration such as the last replica N14c can be visually or functionally more suitable when the teeth are too far inwards, unless the teeth were already too far inwards inclined in the initial state.

[0422] The same teeth Z14a to Z14c are shown in three different positions, where veneers N14a to N14c are used, and their outer contours, especially the frontal outer contours, can remain unchanged or the same. Axes A14a to A14c show the inclination about the inclined axis mentioned above, and the inclined axis is Figure 14 perpendicular to the page in

[0423] The sections St14a to St14c from the midlines of the veneers (tooth replicas) N14a to N14b to a vertical reference line that can be located, for example, in the inclined axis continuously increase and correspond to the expansions or displacements respectively achieved forward by the veneers N14a to N14b.

[0424] The material layer thicknesses D14a, D14b, D14c show the layer thicknesses of the veneers N14a, N14b, and N14c in their front regions. Compared with the layer thickness D14c, the layer thickness D14b is reduced. For example, because the inclination of the tooth Z14b causes a greater reduction in the layer thickness than the increase in the layer thickness caused by the displacement of the veneer N14b. The layer thickness D14c is the same as the layer thickness D14c. For example, because the reduction in the layer thickness caused by the inclination of the tooth Z14c is equal to the increase in the layer thickness caused by the displacement of the veneer N14c relative to the vertical reference line.

[0425] Figure 15 Roughly and schematically show special cases of an intermediate period, where the device 10.n consists of an upper splint 11.n and a lower splint 12.n. During the contact between the lower jaw UK,4 and the upper jaw OK,5, the ramp-shaped functional element 17.n generates lateral and / or front-back oriented force components as a ramp function 270. In the shown example, it is targeted to prevent the overly forward movement of the lower jaw UK,4 in the aspect of a malocclusion called mandibular retrusion (Sunday-Bite). The ramp 17.n in the device 10.n can be gradually positioned and oriented in different ways relative to the molars 56, 57 so as to gradually and carefully move the lower jaw UK,4 backward to a new rest position. At the same time, a solid superstructure with a height function 250 and an obvious sliding surface with a sliding function 260 can be integrated. Therefore, the high structure in the molar region can be solid or high, so that the lower jaw UK,4 also maintains contact occlusion in the actual rest equilibrium position. It can be seen in the jaw joint head 6 that the jaw joint head 6 is far enough from the rear wall 7 of the jaw joint in the upper jaw, see the distance D15. Therefore, the backward migration of the lower jaw caused by the ramp function 270 is a targeted measure. Only through the backward migration of the lower jaw, combined with an obvious height function 250 with a solid or hollow structure in the molar region, can, for example, a severe crossbite be relieved.

[0426] Figure 15Shows an intermediate stage of the kit 100, where the lower incisors 51, 52 have been brought behind the upper incisors. Here is an example where it can be meaningful for the teeth of the lower jaw UK, 4 to remain smaller first and then be reconstructed as part of one or more splints by veneers of appropriate size and shape when they reach the correct position. In fact, in the shortest possible state, the anterior teeth 51 / 52 of the lower jaw UK, 4 can be more easily migrated backward from the malocclusion under the upper incisors. In contrast, in the upper jaw OK, 5, treatment can be carried out from the beginning or from the start through the shape function 230 and the optional color function 240. At the end of the multi-functional treatment using x devices, the last device 10.x can also be planned to be removed according to the treatment plan BP. Then, it can be planned to implement the final medical body 300 using veneers, table tops, etc., while the position of the occlusion plane is preferably selected cranially, and the structural height above the remaining teeth can be maintained.

[0427] Figure 16 Shows a computer system 1600, a computer system 1600 that can execute the method steps mentioned herein, particularly automatically or semi-automatically. The computer system 1600 may include:

[0428] - A computer 1610,

[0429] - An optional input device I, such as one or more keys, an alphanumeric keyboard, a computer mouse, a trackball, a data receiving unit (such as a data receiving unit for receiving data via the Internet or an intranet).

[0430] - An optional output device O, such as a screen (such as a touch-sensitive screen) or a data sending unit (such as a data sending unit for sending digital data via the Internet or an intranet).

[0431] Using the input device, a digital representation of, for example, a person's teeth can be "shifted" on the screen. Alternatively or additionally, a calculation process can be initiated to calculate the device pair 10.

[0432] The computer 1610 may include:

[0433] - One or more processors P, which are configured to execute program instructions, such as program instructions of an operating system (Windows (may be a trademark), IOS (Input Output System) (may be a trademark), Linux (may be a trademark), etc.), particularly program instructions of an application for executing the method steps or parts thereof mentioned herein, and / or

[0434] - A storage unit M, which is designed to store program instructions and / or data, such as data generated when executing program instructions. The storage unit M may include volatile memory (such as RAM (Random Access Memory), DRAM (Dynamic RAM), etc.) or non-volatile memory (SSD (Solid State Drive), EPROM (Electrically Programmable Read-Only Memory), etc.) and / or

[0435] - At least one computer program or computer program product, such as BIOS (Basic Input / Output System), which may be an independent program or part of an operating system OS, and / or

[0436] - Optionally, a bus 1620, which is between one or more processors P and the storage unit M, or between other units of the computer 1610, or between other units of the computer system 1600.

[0437] There may be other units known to those skilled in the art, such as a power supply, an Internet or intranet connection, such as a connection based on Internet Protocol IP, etc.

[0438] A manufacturing machine Ma (such as a computer-aided manufacturing machine (CAM) or a computer numerical control (CNC) milling machine or a three-dimensional (3D) printer) can be connected to the computer system 1600, such as locally or via a data transmission network. A scanning device S (scanner) can also be coupled to the computer system 1600, such as to scan the teeth of a person P or a dental mold of the teeth of a person P, especially in the electronic field and / or the optical field to scan the teeth of a person P or a dental mold of the teeth of a person P.

[0439] Through the model function (veneers), when wearing the first aligner, the final position with, for example, a 10% magnification can be seen or achieved. The magnification can be achieved by values from 1% to 20%, especially values from 5% to 15%. Therefore, the wearing comfort relative to the lips, that is, the balance between the soft tissue and the final position of the teeth, can be integrated from the very beginning.

[0440] By designing different inclined planes between the two aligners, treatment oriented by centricity (the condyle and fossa in the maximum ideal position) can be carried out from the very beginning. The teeth can move inside the splint (device). Through the external structural shape and the resulting encryption, a central condyle trajectory that matches digital volume tomography (DVT) or other imaging methods can be achieved. From a medical perspective, this can be a great advantage of the veneer-aligner. The veneer-aligner acts on CMD and the associated postural discomfort and jaw discomfort from the very beginning.

[0441] For example, early developmental occlusions (e.g., crossbites) often have a distracting dislocation of the condyles. During treatment, for example, the anterior teeth in the upper jaw must be moved forward. During the movement, the teeth to be moved must overcome the obstacle of the lower anterior teeth and finally maintain balance in front of, behind, or above them in the acute stage. This jitter effect can cause serious damage to the affected teeth, and during this period, the jaw joint slides excessively backward (cranial dorsal load vector), for example, into the sensitive bilayer area, which is also an area crucial for the metabolism of the joint disk on the condyle. The bilayer area includes, for example, an upper layer and a lower layer. In the bilayer area, it can sometimes cause significant discomfort or even pain. An anterior bite can only be anterior, and when the muscles are tense, it may have a great lever effect on the jaw joint. This, in turn, can lead to compression of jaw joint problems. All of these can be prevented or significantly alleviated by the design or improvement of the new concept.

[0442] Through the known V.T.O. (Visual Treatment Objective), according to Ricketts (Holdaway) and model analysis (e.g., Staub - Cranial), in KFO (orthodontics), treatment aids (dental devices) for upcoming KFO treatments are currently being planned. The teeth are visually (virtually) migrated in the upper and lower jaws. By this method, three - dimensional repositioning of the teeth and jaws cannot be achieved because parameters determining the sagittal plane (only cephalometric analysis, tele - radiographic analysis), coronal plane, and horizontal position cannot be included, because, for example, only 2D tele - radiographic lateral images are available.

[0443] When planning the "multifunctional dental device", these missing but useful parameters (determinants) can be determined as markers (structural markers), for example, from 3D - Dicom - data (Digital Imaging and Communications in Medicine), including, for example, digital image data (CT (Computed Tomography), CBCT (Cone - Beam Computed Tomography), MRI (Magnetic Resonance Tomography), etc.), which can be used to analyze jaw relationships and tooth status. A feasible analysis method is the cranial analysis according to "CranioPlan", i.e., the "Saxler - analysis".

[0444] Force - conduction disorders in the lower jaw UK, 4 and / or the upper jaw OK, 5 can be identified and resolved in an orthognat or eugnath manner. This can be achieved by an asymmetric thickening (i.e., for example, material thickening or elevation) of the "multifunctional dental device" in the cranial (skull) direction (occlusal plane, dental arch from left to right, from right to left). In addition, torsional moments can be generated by using asymmetric ramps or lateral displacements in the device.

[0445] Determination of the reference structure may include:

[0446] i) Preferably using digital 3D image data, determining the inner ear axis,

[0447] ii) Determining the position of at least one eye,

[0448] iii) Determining at least one cranial plane including the inner ear axis and the position of at least one eye,

[0449] iv) Using the cranial plane as an auxiliary plane or a computationally assisted plane, for example, by determining the average of two planes respectively including the eye positions,

[0450] v) Using the auxiliary plane to determine the occlusal plane in the following manner:

[0451] A1) Determining a torsion axis parallel to the inner ear axis and located on the other side of the inner ear axis compared to the eye axis,

[0452] A2) Using the torsion 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 the target occlusal plane or a plane parallel to the target occlusal plane, or

[0453] B1) Twisting the auxiliary plane around the inner ear axis to obtain a second auxiliary plane,

[0454] B2) Shifting (translating) the second auxiliary plane downward.

[0455] B2) So as to obtain the target occlusal plane or a plane parallel to the target occlusal plane,

[0456] B2) For example, so as to obtain a section through which the shifted second auxiliary plane coincides with the target occlusal plane obtained according to alternative A.

[0457] The exact angle can be determined with the aid of a sphere that is numerically adapted to the digital data describing the foramen magnum, i.e., the large oval opening in the occipital bone (back of the head) of the skull.

[0458] The torsion axis can be determined, for example, by the following method:

[0459] - Determining a first center point of the inner ear axis between two inner ear points,

[0460] - Determining a second center point of the eye axis between two eye points,

[0461] - Determining the distance between the first center point and the second center point,

[0462] - Determining the connecting line between the first center point and the second center point,

[0463] - Extend the connecting straight line backward by a section of length, which is approximately twice the determined distance (for example, 1.5 to 2.5 times or 1.75 to 2.25 times or 1.9 to 2.1 times) in length, to obtain the point through which the axis of torsion passes, that is, the original length of the section between the two center points is magnified three times, for example.

[0464] Cranial plan

[0465] Different from the plane, the method hereinafter referred to as "cranial plan" can still determine and / or consider the so-called Spee Kurve of the occlusal surface of the teeth. In this case, for example, the position of the teeth in the center of the right jawbone (maxilla or mandible) or in the center of the right jaw (maxilla or mandible) will deviate, and the corresponding teeth can be arranged below the occlusal plane.

[0466] According to the method of Hornung (EP 3 332 731 A1), which is incorporated herein by reference for all legal purposes.

[0467] Other methods can use facial features, especially facial features corresponding to the bone features of the facial skull mentioned above. See, for example, US 2015 / 0265374 A1, which is incorporated herein by reference for all legal purposes. Thus, the radiation load caused by X-rays can be reduced or decreased.

[0468] The cranial plan method can be performed manually, semi-automatically or automatically, especially computer-aided.

[0469] In another embodiment, determining the reference structure may include:

[0470] - 3D imaging and generating digital data,

[0471] - Manually identifying or automatically identifying anatomical landmarks,

[0472] - Using the identified anatomical landmarks to define the transverse direction, thereby also determining the direction of the sagittal plane,

[0473] - Determining the center points between the anatomical landmarks,

[0474] - Placing the median sagittal plane Sm at the determined center points,

[0475] - Using a digital 3D structure marker including at least three plane packages:

[0476] - 1) A transverse plane package, which includes a plurality of transverse planes parallel to each other,

[0477] - 2) A frontal plane package, which includes a plurality of frontal planes parallel to each other, and

[0478] - 3) At least one sagittal plane packet, which includes a plurality of sagittal planes parallel to each other,

[0479] - Introduce 3D structure markers into the 3D image space,

[0480] - Orient the 3D structure markers to the midsagittal plane Sm,

[0481] - Translate the 3D structure markers to a first anchor point, which is preferably located in the midsagittal plane,

[0482] - Twist the 3D structure markers using a second anchor point,

[0483] - Scale the 3D structure markers using a third anchor point,

[0484] - Determine the ideal occlusal plane using the 3D structure markers.

[0485] The following describes a preferred method. First, determine the transverse direction according to anatomical markers (Part A), and then perform further adaptation steps (Part B). Here, the user can create an axis (such as 215) at the anatomical markers (such as the zygomatic bone, eye socket, or inner ear region) in the image plane or create a plane perpendicular to the image plane, because this plane appears as a line in the cross-sectional view.

[0486] Part A

[0487] - 1) - 3D imaging: In the first step, image generation of a 3D image of a body part (such as the patient's head) can be achieved.

[0488] - 2) Generate digital data: By processing the image, a digital or virtual 3D body can be generated in the second step.

[0489] - 3) Visualization: In the third step, cross-sectional views of this 3D body can be displayed.

[0490] - 4) Identify anatomical markers: In the fourth step, markers of bone structures can be identified in appropriately selected cross-sectional views.

[0491] - 5) Define the transverse direction: In the fifth step, at least one transverse direction can be defined, which connects two symmetric markers, for example. This can be achieved by an axis or by a plane and a second plane intersecting it.

[0492] - 6) Define the orientation of the sagittal plane: In the sixth step, the position of the sagittal plane (Sm) can be defined, whose orthogonal normal is the transverse axis.

[0493] -7) Determine the center point: In the seventh step, the center 211 can be determined between suitable markers so that the median sagittal plane Sm of the upper cranial bone can be accurately determined. This may not be entirely clear or may not provide a certain degree of freedom because the cranial bone usually has a different orientation in the posterior region from that of the anterior upper facial cranial bone, up to 2 degrees.

[0494] -8) Determine 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 resulting from the determined transverse direction.

[0495] -9) Check other views: In the optional ninth step or in multiple such steps, other cross-sectional views can be obtained to control the position and orientation or to complete other tasks and problems.

[0496] In part A, the order of the steps can be changed as long as the result is to define the orientation of the sagittal plane with the help of anatomical markers.

[0497] For part B, the following 3D (three-dimensional) structure markers (abbreviated as markers or rulers) can be used, which can include at least three plane packs:

[0498] -1) A plane pack that includes a plurality of transverse planes parallel to each other,

[0499] -2) A plane pack that includes a plurality of frontal planes parallel to each other, and

[0500] -3) At least one plane pack that includes a plurality of sagittal planes parallel to each other, such as a left sagittal plane pack and a right sagittal plane pack.

[0501] The known Fibonacci sequence or Fibonacci arrangement is: 3, 5, 8, 13, 21, etc., that is, the next term in the sequence is the sum of the previous two terms. This order can be used to determine the distance between the planes in the three plane packs. For example, the distance between the first two planes is 3 mm from each other, the distance between the second plane and the third plane is 5 mm from each other, the distance between the third plane and the fourth plane is 8 mm from each other, etc.

[0502] Part B

[0503] -1) Add 3D markers: In the first step, the 3D structure markers can be introduced and inserted into the 3D image space so that the 3D structure markers can be seen in the view. At this time, the plane packs are only shown as parallel lines.

[0504] -2) Orient the 3D markers to the median sagittal plane Sm: In the second step, the structure markers can be oriented with their internal sagittal plane structure perpendicular to the transverse axis of the bone structure.

[0505] -3) Translating the 3D marker: In an independent third step 830, the 3D structural marker can be placed on the anchor point in the midsagittal plane. In an embodiment, for example, at the base point BP of the foramen magnum, at the intersection of the line or plane T3 (the third transverse plane) and F5 (the fifth frontal plane) in the midsagittal plane Sm.

[0506] -4) Twisting the 3D marker: In the fourth step, the 3D structural marker can be oriented by rotating (twisting) about an axis parallel to the transverse axis such that in the sagittal plane image, the transverse plane extends along the direction of the connecting line, for example, along the direction of the axis BP-GP (gnathion point). In an embodiment, the rotation can be performed about the fixed point where the intersection points T3 and F5 are located. The rotation positions the line T3 to pass through two anchor points (for example, the base point BP and the gnathion point (GP)). Thus, the 3D structural marker 500 is oriented at an angle.

[0507] -5) Scaling the 3D marker: In the fifth step, the frontal line can be made to pass through a suitably selected anchor point 601 by linear scaling of the marker or the dimensions of the 3D structural marker. In an embodiment, the anchor point 601 is the nasion point NP (Nasionspunkt). In an embodiment, when the frontal line F1 and thus the frontal plane pass through the nasion point or the Nasionspunkt NP, the correct individual scaling dimension is achieved.

[0508] -6) Analyzing symmetry: In a subsequent optional sixth step, the symmetry and harmony of the proportions of the body part can then be selectively analyzed. Here, inclinations are often shown, for example, the inclination of the mandible and the current occlusal plane.

[0509] -7) Determining the ideal occlusal plane: In a further seventh step, for example, the first transverse plane (T1) can be used as the ideal occlusal surface or the ideal occlusal plane for subsequent alignment of, for example, a denture or a device. The first transverse plane 501.1 (T1) can pass through the incisal point or the incisal point IP, that is, the contact point of the incisal edges of the two lower central incisors, which can be achieved especially by using the Fibonacci sequence. In the case of a separable device with an upper and a lower part, particularly preferably, the separation plane between the two parts can be implemented as a separation-sliding plane, that is, for example, without a retaining member (protrusion) and having very low friction and / or roughness, for example, less than 5 micrometers. When planning and shaping the device, the position of the separation-sliding plane in the digital or virtual 3D space can be placed as precisely as possible at the position of the ideal occlusal plane, or if the ideal occlusal plane cannot be used or should not be used due to medical or other reasons, on a plane parallel to it.

[0510] The order of the steps in part B can be changed.

[0511] In part C after determining the ideal occlusal plane, regardless of the method used to determine the occlusal plane, the following steps can be carried out to manufacture one or more training devices in the kit consisting of the devices:

[0512] - In the eighth step after the seventh step, free space can be created for the teeth and / or dental implants of the upper and lower dental arches so that the device can be precisely mounted on each dental arch later without pinching or damaging the gums. Subtraction operations can be used here. Marginal gaps can also be considered.

[0513] - In the eighth step, by completing the digital model in the eighth step, precise definition of the position of the device and its two parts in the mouth can be achieved using, for example, a planned form fit only at specific contact points between the device and the dental arch.

[0514] - In the subsequent ninth step, the device can be manufactured in its parts and fully customized for this situation and then used for this patient.

[0515] According to the 3D markers or 3D scales of Saxler and Hornung, see WO 2020 / 141134 A1. This document is incorporated herein by reference for all legal purposes.

[0516] Other methods can use facial features, especially facial features corresponding to the bone features of the facial skull mentioned above, see for example US 2015 / 0265374 A1, which is incorporated herein by reference for all legal purposes. Thereby, the radiation load caused by X-rays can be reduced or decreased.

[0517] In other embodiments, the occlusal plane can be determined using a method different from the methods according to Hornung (EP 3 332 731 A1) or according to Saxler, Hornung (3D scale, WO 2020 / 141134 A1).

[0518] The 3D marker / scale method can be performed manually, semi-automatically or automatically, especially computer-aided.

[0519] The determined occlusal plane can be the same in both methods (cranial planning, 3D marker / scale), but this is not necessary. In both methods, three solid angles of the normal of the occlusal plane with the three coordinate axes of the Cartesian coordinate system and three position coordinates relative to the three coordinate axes, i.e., a total of 6 parameters, can be considered.

[0520] Unlike in the case of a plane, in the above-described "3D marking / ruler" method, the so-called Spee curve of the occlusal surface of the teeth can still be determined and / or taken into account. In this case, for example, there is a deviation in the position of the teeth in the center of the right jawbone (maxilla or mandible) or in the center of the right jaw (maxilla or mandible), where the corresponding teeth can be arranged below the occlusal plane.

[0521] Alternatively, other suitable methods can be used to determine the target occlusal plane.

[0522] A kit 100 is described that consists of devices for gradually changing the position of the teeth of a person P, the kit including at least two devices 10.

[0523] Wherein the devices 10 each include at least one jaw device 11, 12.

[0524] Wherein at least one of the jaw devices 11, 12 is designed such that the receiving areas of the jaw devices 11, 12 can be placed on the dental arches of the maxilla OK, 5 or the mandible UK, 4 of the person P.

[0525] Wherein the devices 10 are designed such that when the devices are worn in a predetermined order according to the devices, the devices gradually change the tooth position through the mechanical interaction of the devices and at least one tooth element.

[0526] Wherein at least one of the jaw devices 11, 12 of the first devices 10.1, 10.2 has on its outer side first veneer elements N.I.1.2, N.IV.1.2 that are sub-regions of the first devices 10.1, 10.2.

[0527] Wherein at least one of the jaw devices 11, 12 of the second devices 10.n has on its outer side second veneer elements N.I.1.n, N.IV.1.n that are sub-regions of the second devices 10.

[0528] Wherein the first veneer elements N.I.1.2, N.IV.1.2 are located at the same positions as the second veneer elements N.I.1.n, N.IV.1.n according to the tooth scheme.

[0529] Wherein the receiving areas of the first veneer elements N.I.1.2, N.IV.1.2 are designed to be different from and / or have a different position from the receiving areas of the second veneer elements N.I.1.n, N.IV.1.n.

[0530] Wherein this difference is suitable for causing a gradual migration of the tooth elements, and

[0531] Among them, the front side wall thicknesses of the second veneering elements N.I.1.n, N.IV.1.n are different from those of the first veneering elements N.I.1.2, N.IV.1.2.

[0532] In addition, a method for designing a multifunctional dental device is explained, including:

[0533] - Recording the initial tooth arrangement of the teeth of person P in their upper jaw and / or the teeth of person P in their lower jaw, preferably simultaneously recording at least one cranial feature and / or facial structure / feature in the cranial region of person P,

[0534] - Determining at least one reference structure, such as a cranial reference structure, of person P before, during, or after the recording,

[0535] - Determining the target tooth arrangement of the teeth of the upper jaw OK, 5 of person P relative to the reference structure,

[0536] - Determining the target tooth arrangement of the teeth of the lower jaw UK, 4 of person P relative to the upper jaw UK, 4 of person P or the target upper jaw UK, 4 while considering the reference structure,
