METHOD FOR ANIMATED PICTURE REPRESENTATION OF MOVEMENTS OF THE TEETH OF THE LOWER JAW AND SYSTEM FOR ITS IMPLEMENTATION

Description

[0001] The invention relates to a method for the animated pictorial representation of movements of the teeth of the mandible, which ultimately serves to record the bite position and / or movement parameters of anatomical points of the mandible and / or the jaw relationship and / or the occlusion in a vertebrate, in particular a human. It further relates to a system for carrying out this method.

[0002] Mechanical and, more recently, virtual articulators are used to perform dental restorations and fabricate dentures and occlusal splints. This requires determining the patient's bite position. Traditionally, this is done using a mechanical facebow with a bite plate placed in the mouth. The position of the bite plate relative to the ear canal (which is related to the condyles) and the nasion (or orbital point) in the facial region is measured. The measured bite position is then transferred to the mechanical articulator using a plaster cast of the upper jaw.

[0003] Furthermore, it is necessary to determine movement parameters of anatomical points of the mandible, in particular the movement characteristics of the condyles (left and right) as well as those of the front teeth, and to set the key figures of the movement paths on the articulator.

[0004] Furthermore, it can be important to determine a new therapeutic jaw relationship or a correct bite between the teeth of the upper and lower jaws. An existing habitual bite – possibly with abraded teeth – can have negative aesthetic and functional effects and can also trigger temporomandibular joint dysfunction (TMD).

[0005] Furthermore, it is important to obtain information about the occlusion. Traditionally, a staining occlusal foil is used for this purpose. A correct occlusion – even during movement – ​​increases wearing comfort and the durability and lifespan of dental prostheses. Modern ceramic materials no longer wear down naturally but tend to fracture and / or damage healthy opposing teeth.

[0006] DE 102 18 435 A1 describes a method and a device for the 3-dimensional motion analysis of tooth surfaces of the mandible in relation to the maxilla. A sensor holder for the mandible is shown, which can support a position sensor.

[0007] Specifically, DE 102 18 435 B4 describes a motion measurement system and a paraocclusal attachment for securing a motion sensor to the mandible. The attachment consists of a tooth-mounted attachment and a sensor holder to which motion measurement sensors or markers of the motion analysis system (such as ultrasonic or optical markers) can be attached. Alternatively, the sensors of the motion measurement system can be directly and detachably connected to the tooth-mounted attachment. Motion measurement sensors can include, for example, camera or laser sensors, magnetic sensors, or sensors based on accelerometers or gyroscopes, or combinations thereof. To compensate for head movements, reference or receiver sensors are attached to the maxilla or via a headgear. Furthermore, stationary sensor systems, such as cameras, may be required.

[0008] A relevant method for the animated visual representation of movements of the teeth of the mandible for recording the bite position and / or movement parameters of anatomical points of the mandible and / or the jaw relation and / or the occlusion of a vertebrate, as well as a corresponding system, are known from JP 2020 501 830 A. DE 10 2018 26 097 A1 also discloses a method and system with this purpose, which is based on scanning the tooth surfaces on the one hand and on position and / or dynamic movement recording of the mandible with a suitably designed position sensor attached to the mandible on the other.

[0009] Further relevant state of the art is CN 112 790 888 A.

[0010] In procedures of the type described above, a serially manufactured attachment (hereinafter also referred to as a position sensor holding device) is fixed to the patient's mandible, and position and movement data are recorded using this attachment. In a separate step, an image of the tooth surfaces is obtained by directly scanning them with an intraoral scanner or by traditionally creating an impression of the tooth surfaces using a bite fork filled with impression material and then scanning this impression (extraorally).

[0011] The invention is defined by the independent claims.

[0012] The invention is based on the objective of providing an improved, in particular simplified and more accurate method of the generic type, as well as a position sensor holding device and a corresponding system suitable for such a method.

[0013] This problem is solved in its method aspect by a method according to claim 1 or 2 and in its apparatus aspect by a system according to claim 6 or 7. Advantageous developments of the inventive concept are the subject of the respective dependent claims.

[0014] The invention includes the idea of ​​simplifying the conventional method by using a position sensor holding device, which allows the direct and exact establishment of a positional relationship between the patient's tooth surfaces and the position sensor.

[0015] This eliminates the need for an additional bite fork, or at least simplifies the procedures performed with the patient. Attaching the measuring sensors to the teeth is quick, easy, mechanically stable, and highly precise with such a holding device. Because the position sensor holding device used in the proposed procedure inherently incorporates a positional relationship between the tooth surfaces and the position sensor attached to the holding device, time-consuming calibration steps are eliminated, and inaccuracies that are unavoidable when using non-specific, standard holding devices and the potential additional use of a bite fork are avoided. Furthermore, the greater convenience of the proposed procedure for the patient and the resulting greater acceptance in dental practice are worth mentioning.

[0016] In a variation of the procedure, an integrated (one-piece) holding / sensor device is designed and manufactured directly from the tooth surface data obtained through scanning. This device incorporates position sensors, i.e., corresponding position marker elements. This eliminates the need to assemble a standard-sized position sensor with a patient-specific position sensor holding device, thus simplifying handling in dental and oral surgery practices.

[0017] This modification of the inventive method is also reflected in the fact that, in the inventive system, instead of a position sensor holding device and separate position sensors, the aforementioned integrated holding / sensor device is designed, manufactured and used in the position and / or motion measurements.

[0018] It should be noted that, in addition to the aforementioned tooth surface data, surface data of the adjacent gums, which are scanned together with the teeth, can optionally also be used in the procedure and system.

[0019] Furthermore, it should be noted that the actual (optical) visual representation or the corresponding display device (screen) is not necessarily required for every application of the procedure and system. The underlying moving image data can also be directly incorporated into further evaluations or diagnostic steps and optionally displayed visually in such an expanded context.

[0020] In a practically significant implementation of the procedure, the tooth surface data obtained by scanning are fed to a computing unit of a CAD design device, and the position sensor holding device is designed using a CAD method.

[0021] In further practically significant embodiments, the position sensor holding device is three-dimensionally milled from a prefabricated plastic part using the tooth surface data obtained through scanning. Accordingly, in preferred embodiments of the system, the production equipment includes a milling machine for milling at least the surface of the position sensor holding device facing the teeth from a prefabricated base body, or a 3D printer for the additive manufacturing of the position sensor holding device, particularly from a polymer material.

[0022] One important application of the proposed method is a procedure for recording the bite position and / or jaw relation and occlusion with additional reference measurement in a defined position of the mandible relative to the maxilla, especially in habitual occlusion.

[0023] In this practically significant application, the procedure further comprises the following steps: Scanning of the upper jaw and animated representation of the movement of the teeth of the lower and upper jaw in conjunction with the tooth surface data and positional relation data, scanning of at least one contiguous tooth surface of the upper and lower jaw in a defined closed jaw position to determine a starting position of the animated pictorial representation of the movement of the teeth.

[0024] In this process, the predefined position is specifically secured with registration material.

[0025] In a corresponding extension of the system, the position measuring system includes a facebow component that interacts with the sensor device attached to the teeth and is fixed to a facebow attached to the head of the vertebrate, or a spatially fixed component.

[0026] Regarding the part of the proposed method and system relating to position measurement, as well as the aforementioned application / extension, it should be noted that these are generally known to those skilled in the art, particularly from the applicant's publications on intellectual property rights. Since reference can be made to this readily available knowledge, a detailed description of these steps, components, and implementations is omitted here.

[0027] The position sensor holding device used in the process, which forms a central component of the proposed system, comprises a base body shaped in an arc shape to adapt to the tooth row of the lower jaw of a vertebrate, one surface of which is designed to be placed on the lower jaw according to an image of the tooth surfaces of at least one section of the lower jaw, and a sensor device holding element which is designed for the position- and angle-accurate attachment of a position sensor to the base body.

[0028] In one embodiment of the position sensor holding device, this includes posterior support sections for support in the area of ​​the posterior teeth and optionally the underlying gingiva, wherein each posterior support section is shaped such that it extends at least partially in a mesial direction over or under a posterior tooth and over the adjacent gingiva.

[0029] In another embodiment, the base body and the holding element are formed in one piece and are manufactured, in particular, by a milling process or a 3D printing process. It is understood that the associated position sensor has a connector adapted to the holding element of the holding device. Such holding element / connector combinations are also known to those skilled in the art.

[0030] In another embodiment, the base body, the holding element, and the position sensor are formed in one piece and are essentially manufactured using a milling process or a 3D printing process. It is assumed here that the position sensor contains features that can be recognized and processed by a position measuring system.

[0031] It is also possible in one version to add position sensor components to such a milled or printed device, which are either removable or remain permanently attached to the base body.

[0032] The invention will now be described with regard to further features and advantages using exemplary embodiments, which are explained in more detail with reference to the figures. These show: Fig. 1 a schematic representation of an embodiment of the method according to the invention; Fig. 2 a schematic representation of an embodiment of the system according to the invention; Fig. 3 an embodiment of a position sensor holding device in a schematic oblique view; Fig. 4 an extended embodiment according to Fig. 3 in a top view; Fig. 5 an embodiment with a plateau in a top view; Fig. 6 the embodiment according to Fig. 5 in a side view; Fig. 7 another embodiment of the attachment according to the invention, in a perspective view; Fig. 8 another embodiment, in a side view and Fig. 9 Another embodiment in a perspective view, together with a lower jaw.

[0033] In the following description, largely the same reference numbers are used for identical and similarly functioning parts.

[0034] Fig. 1 shows a schematic representation of a procedure for recording jaw relation and / or occlusion.

[0035] In step S1, the surfaces of mandibular teeth are first captured and stored, preferably using an intraoral scanner. In step S2, a position sensor retention device, comprising at least one retention element for holding a position sensor (or a retention element with integrated position sensor), is designed using this tooth surface data. The retention device is adapted to the captured surfaces so that, when placed on the maxilla, it is positioned in a predefined position and orientation relative to the teeth and preferably does not impede the sliding of the maxillary teeth towards the mandibular teeth.

[0036] In step S3, which can be performed entirely or completely during or following step S2, position relation data for the relative position and relative orientation of a position sensor connected to the holding device are stored relative to the surface of the position sensor holding device adapted to the scanned tooth surfaces.

[0037] In step S4, the attachment is either machined from a prefabricated base body using a subtractive machining process or built up step by step from polymer granules or a polymer paste, etc., using 3D printing or additive manufacturing. Then, in step S5, a position sensor is fixed or completed on the attachment's holding element with precise positioning and angular accuracy (unless it has already been integrated in the previous steps).

[0038] In step S6, the attachment with the position sensor fixed to it is placed on the patient's lower jaw and stays in place solely due to its precise surface fit, or it is additionally temporarily fixed using an adhesive cream and / or a two-component or light-curing adhesive material, for example.

[0039] The patient then performs predetermined mandibular movements, and in step S7, positional and movement data of the mandible are recorded using position sensors in conjunction with a position measuring device (see below). In step S8, this positional and movement data, along with the aforementioned tooth surface and positional relation data, is processed using a conventional simulation program to create an animated representation of the mandibular movements. This data can subsequently be used, among other things, to determine the jaw relation and, if the maxillary tooth surfaces have been scanned, to depict the occlusion with the maxillary teeth, according to a known procedure.

[0040] The figure uses dashed lines to symbolize that the process comprises a design and manufacturing section P and a measurement and evaluation section M, which are usually separated spatially and temporally.

[0041] This also corresponds to the structure of a corresponding embodiment of the system according to the invention, as shown in Fig. 2 is depicted in a sketch-like manner.

[0042] The manufacturing and measuring system 100 comprises an intraoral scanner 101, which is shown schematically in use for scanning the mandibular (UK) tooth surfaces of a patient P. The intraoral scanner 101 is connected, for example via an interface, to a data storage unit 102a of a CAD system 102 for the design of a position sensor holding device according to the invention, and the tooth surface data are stored there. Furthermore, geometric data of a position sensor, designated here by the number 103 and symbolically represented as a cuboid, is stored in the data storage unit 102a. This sensor is designed for positionally and angularly accurate fixation to the attachment.

[0043] In a computing unit 102b of the CAD system 102, a patient-specific position sensor holding device, designated here by the number 104, is designed using the input data. The illustration shows a version with removable position sensors. In parallel, a position relation dataset is provided, which is formed from the CAD data of the position sensor holding device and the design data of the position sensors and defines the geometric relationship between the position sensor device and the tooth surfaces of the mandibular teeth onto which the attachment is placed during use.

[0044] The position sensor mounting device is manufactured in a 3D printer 105 (or a milling machine) using the design data from the CAD unit. If not already integrated, the position sensor 103 is then fixed to the attachment, and the attachment is placed on the patient's mandible.

[0045] The figure shows that the patient also wears a facebow 106 with additional position sensors 107, which are not essential for the present invention. However, they can be used to determine the jaw relation and / or occlusion (in a manner known per se) when the motion data is used following the claimed method. Methods are conceivable in which the additional sensors 107 and / or the facebow 106 can be dispensed with.

[0046] In conjunction with the position sensor 103, a stationary position measuring system 108 dynamically records the position data of the mandible and thus the mandibular tooth surfaces of the patient during predefined movements. The stationary position measuring system 108 can alternatively be worn on the head and correspond to the position sensor 103 at the position of the sensor 107. The position measuring system 108 is connected at its output to a motion image synthesis unit 109, which generates an animated (virtual) representation of the mandibular movement from the movement data, the CAD data of the position sensor holding device 104 (corresponding to the tooth surface data), and the position relation data. This is displayed on a screen 110; however, the data sets of the virtual movement can also be directly fed into downstream evaluation or diagnostic steps.

[0047] Analogous to the schematic representation of the procedure in Fig. 1 is in Fig. 2 The system is divided into a production sphere 100P and a measurement sphere 100M, symbolized by dashed lines.

[0048] Fig. 3 Figure 1 shows an exemplary position sensor mounting device 1, comprising an arc-shaped base body 2 and a mounting element 3 integrally molded to it, in the position attached to the mandibular occlusion of a patient. The position sensor mounting device can be constructed using a 3D printing technique from a polymer granulate or polymer paste and has a surface facing the teeth and gums of the mandible that is precisely adapted to the corresponding sections of the teeth and gums. As explained above, this is achieved by scanning the tooth surfaces and adjacent gum surfaces and using this tooth surface data in a CAD design process for the position sensor mounting device.

[0049] In the Fig. 3 In the illustrated version, the position sensor holding device is shaped in such a way that it completely encloses the posterior molars of the lower jaw, so that the holding device can be attached to the lower jaw teeth in a "snap-fit" and sits there in a precisely predetermined position, if necessary even without the use of an adhesive cream or similar.

[0050] Fig. 4 Figure 1 shows a particular embodiment of the position sensor holding device 1 together with an intermediate holding device 4a, which can be detachably connected to the position sensor holding device 1 and which in turn contains a holding device for the position sensor 4. An example shown here is a metal plate with three alignment marks 4b, onto which a position sensor 4 equipped with magnets can be placed with precise positioning.

[0051] By means of a connecting piece 5, the intermediate holding device 4a (or alternatively, the position sensor 4 directly) can be connected to the holding element 3 of the position sensor holding device 1 with precise positional and angular accuracy. The holding element 3 of the holding device 1 and the connecting piece 5 of the position sensor device 4 can, for example, have matching threaded sections or, in particular, locking elements in the form of a bayonet fitting. The tooth surface profile 2a in the base body 2 of the holding device 1 is also shown in the figure.

[0052] Fig. 5 und 6 Figure 1 shows a modified position sensor holding device 1 in a top and side view, in which a projection 6 with a plateau 6a is additionally formed between the arc-shaped base body 2 and the holding element 3. During corresponding jaw movements, the anterior teeth of the upper jaw can contact the plateau 6a, effectively decoupling the upper teeth from those of the lower jaw and preventing occlusion, particularly for determining a new bite position. The height of the projection 6 can preferably be selected according to the height of a future bite position of an occlusal appliance or dental restorations.

[0053] Fig. 7 Figure 1 shows – again schematically – another modified position sensor holding device 1, connected to a position sensor 4. In this case, the arc-shaped base of the holding device 1 does not close behind the posterior molars of the mandible, but only encloses an anterior portion of the mandible. Additional fixation for the movement / measurement process using adhesive material may be useful, but this does not significantly impair the precise positional relationship between the sensor 4 and the surfaces of the mandibular teeth. The position sensor 4 is shown here as an integral and non-removable component of the position sensor holding device 1. It is assumed that the position sensor 4 contains measuring elements or position markers that can be detected by a position measurement system.

[0054] Fig. 8 Figure 1 shows a further modified version in which the retaining element 3 includes an upward bulge 3a. This makes the retaining device more comfortable to wear, especially when performing chewing movements as a predetermined movement that is to be measured.

[0055] While the position sensor holding devices are based on Fig. 3 bis 8 This is a so-called paraocclusal attachment, in which the teeth of the lower and upper jaw can come into occlusion and thus tooth-guided movements are possible, as shown. Fig. 9 an occlusion-covering holding device 1 with attached position sensor 4.

[0056] The occlusal surface 2b of the arc-shaped base body 2 can include a tooth or other selectable structure, or it can be flat. Such a flat surface can be used to define a bite position during a closed jaw position measurement. In any case, the (not visible) surface of the base body 2 facing the teeth Z of the mandible is precisely adapted to the tooth surfaces due to the use of a tooth surface scan during the design and manufacture of the position sensor holding device 1. The rigid fixation of the sensor device 4 to the holding device 1 ensures the existence of an exact positional relationship between the (not shown) markers of the sensor device and the tooth surfaces of the teeth Z, thus enabling a direct animated image representation of the tooth movements without the need for a further scan of the tooth surfaces.

[0057] In a preferred application of the proposed method and system, the teeth of the upper jaw and those of the upper and lower jaws are additionally scanned together in occlusion (buccal or vestibular scan), so that a defined starting position exists for the virtual representation. This "calibration position" can be created in habitual occlusion or by means of an inserted hardening material. The starting position of the movement measurement should correspond to the respective scan position.

[0058] In a special embodiment, a virtual occlusion analysis can also be performed with an occlusion-covering attachment according to Fig. 9This can be performed even though no tooth contact is possible. The procedure is as follows: The teeth of the upper and lower jaw are scanned. Then, the points of the temporomandibular joints are determined, for example, with a stylus, in relation to the position sensor and thus in relation to the attachment and the teeth. For the occlusion analysis, the teeth of the lower jaw are guided in the posterior region according to the movement patterns of the two temporomandibular joints, while in the anterior region they virtually glide on the tooth surfaces.

[0059] For the sake of completeness, it should be noted that in addition to using a stylus, there are several other ways to determine the position of both condylar positions in a patient. One can perform a rotational movement of the mandible in the posterior condylar position and determine the pivot points, or one can perform a wide opening movement and a forward movement of the mandible and, through iteration, determine points where the movement patterns of the condylar pathways are identical. Furthermore, it is possible to align the facebow with the external auditory canal and thus with the temporomandibular joints.

[0060] The skull-related chewing or occlusal plane required for placing the maxillary position in mechanical or virtual articulators can thus be determined from the specific position of the condyles and from an averaged plane of the surface of the mandibular teeth in the closed state and / or the plane of the meeting point of the mandibular tooth surface with the maxilla.
