[0034] Figure 1 A flowchart of a virtual bracket guide generation method provided by an embodiment of the present disclosure is shown in the figure. The method can be executed by a virtual bracket guide generation device, which can be implemented by software and / or hardware and generally integrated in an electronic device. As shown in the figure, the method comprises: Figure 1

[0035] Step 101, determining the corresponding bracket of each tooth and the fixed position of the bracket on the tooth based on the pre-designed orthodontic plan.

[0036] The orthodontic plan is a digital design for each tooth in the user's mouth to be bonded with a bracket, i.e., a design plan for determining which tooth to apply which bracket and where to paste each bracket on the tooth. More specifically, based on the orthodontic plan designed by the doctor, the appropriate bracket (such as the appropriate brand type, different brand type bracket data) is selected and adjusted to the tooth, i.e., the bracket is accurately pasted on the tooth.

[0037] In the embodiments of the present disclosure, a three-dimensional tooth model of the user's mouth can be obtained by three-dimensional scanning and displayed. A set of brackets can be selected to pre-design the displayed three-dimensional tooth model, i.e., to design and bond brackets for each tooth of the three-dimensional tooth model on the display interface. The bracket can be seen to be placed in a reasonable position on the tooth, so that the specific bracket corresponding to each tooth can be determined, and the mapping relationship of the specific bracket corresponding to each tooth can be saved.

[0038] Specifically, according to the pre-designed orthodontic plan, the bracket corresponding to the tooth can be determined, such as tooth No. 1 corresponding to bracket A, tooth No. 2 corresponding to bracket B, etc. Bracket A is pasted on tooth No. 1 and the position of bracket A is adjusted, and bracket B is pasted on tooth No. 2 and the position of bracket B is adjusted.

[0039] Step 102, obtaining the corresponding bracket locator model based on the bracket, and obtaining the relative position of the bracket locator model and the corresponding tooth based on the fixed position of the bracket on the tooth.

[0040] ​Each bracket has a corresponding bracket positioner model, which is a kind of layout model, namely a jig model. The bracket positioner model is connected with the bracket and is used for bracket positioning.

[0041] In the embodiments of the present disclosure, there are many ways to obtain the bracket positioner model matched with the bracket. In some embodiments, the bracket identifier of the bracket is determined, the bracket positioner model identifier matched with the bracket identifier is obtained by querying the pre-stored model database based on the bracket identifier, and the bracket positioner model is determined based on the bracket positioner model identifier. In other embodiments, the bracket positioner model matched with the bracket is generated based on a preset model generation algorithm. For example, the outer envelope surface of the bracket is filled with a corresponding position to form the inner side surface of the bracket positioner model to place the physical bracket. The present disclosure does not make specific limitations on the model generation algorithm.

[0042] The above two ways are only examples of obtaining the bracket positioner model matched with the bracket, and the embodiments of the present disclosure do not make specific limitations on the implementation manner of obtaining the bracket positioner model matched with the bracket.

[0043] Further, after the bracket positioner model corresponding to the bracket is determined, the fixed position of each bracket on the tooth is determined in step 101. Based on the matching relationship between the bracket and the bracket positioner model, the relative position of the bracket positioner model and the corresponding tooth can be determined.

[0044] In step 103, a guide plate model of the tooth is generated based on the tooth information, the bracket positioner model, and the relative position of the bracket positioner model and the corresponding tooth.

[0045] The tooth information of the tooth can be the generation direction, tooth size, and other information of the tooth. The guide plate model of the tooth refers to the guide plate model connected with the bracket positioner model and fitted with the tooth.

[0046] In the embodiments of the present disclosure, the guide plate model of each tooth can be generated by processing each tooth, or the guide plate model of the tooth can be generated by grouping the teeth and processing the tooth groups according to the application scenario.

[0047] In one embodiment, the tooth size and growth direction of the tooth are determined, and the guide plate model matched with the tooth is generated based on the tooth size, generation direction of the tooth, bracket positioner model, and relative position of the bracket positioner model and the corresponding tooth.

[0048] In another embodiment, the teeth are grouped to obtain a plurality of tooth groups, and the guide plate model matched with each tooth in the tooth group is generated based on the tooth size, generation direction, bracket positioner model, and relative position of the bracket positioner model and the corresponding tooth of each tooth in the tooth group.

[0049] In step 104, a virtual bracket guide is determined based on the guide plate model.

[0050] The virtual bracket guide can be printed into a physical guide plate model for pasting brackets. The guide plate model of the tooth refers to a guide plate model connected with the bracket locator model and fitted with the tooth. The virtual bracket guide refers to a model connecting the generated guide plate models and consistent with the sequence of the tooth. The virtual bracket guide can be printed into a physical guide plate model for pasting brackets. For details, see the example description of the subsequent embodiments.

[0051] In the embodiments of the present disclosure, there are many ways to determine the virtual bracket guide based on the guide plate model. In some embodiments, the corresponding guide plate models are connected in the order of the teeth based on a preset connection algorithm to determine the virtual bracket guide.

[0052] In some other embodiments, the guide plate models corresponding to each tooth group are connected and operated after the connection algorithm is applied to determine the virtual bracket guide.

[0053] The connection algorithm is preset, for example, a Boolean operation algorithm, which is selected and set according to the application scenario.

[0054] The above two methods are only examples of determining the virtual bracket guide based on the guide plate model. The embodiments of the present disclosure do not specifically limit the implementation of the virtual bracket guide based on the guide plate model.

[0055] The virtual bracket guide generation scheme provided by the embodiments of the present disclosure determines the brackets corresponding to each tooth and the fixed position of the bracket on the tooth based on a preset correction scheme, obtains the bracket locator model corresponding to the bracket based on the bracket, and obtains the relative position of the bracket locator model and the corresponding tooth based on the fixed position of the bracket on the tooth. The guide plate model of the tooth is generated based on the tooth information, the bracket locator model, and the relative position of the bracket locator model and the corresponding tooth. The virtual bracket guide is determined based on the guide plate model. By using the above technical scheme, the virtual bracket guide consistent with the pre-designed correction scheme can be generated, and then the physical guide plate model can be printed. The brackets can be pasted according to the pasting position designed in the correction scheme. The position of the bracket in the digital design scheme can be converted into the actual pasting position of the bracket in the user's mouth. The purpose of quickly and accurately positioning the bracket position can be achieved, and the use requirements of the user can be met.

[0056] Figure 2 Another flowchart of a virtual bracket guide generation method provided by the embodiments of the present disclosure is shown in the figure. Based on the above-mentioned embodiments, the virtual bracket guide generation method is further optimized. As shown in the figure, the method comprises the following steps. Figure 2 ​

[0057] Step 201: Determine the brackets corresponding to each tooth and the fixed positions of the brackets on the teeth based on the pre-designed orthodontic plan.

[0058] For example, Figure 3 This is a schematic diagram of an orthodontic solution provided in an embodiment of the present disclosure. The diagram shows an orthodontic solution that includes multiple teeth 10 and corresponding brackets 20.

[0059] Specifically, first, a set of brackets (3D model data) is selected to design an orthodontic plan. The designed plan (i.e., the orthodontic plan) shows that bracket 20 is placed in a suitable position on tooth 10, such as... Figure 3 As shown.

[0060] Step 202: Determine the bracket identifier of the bracket, query the pre-stored model database based on the bracket identifier, obtain the bracket locator model identifier that matches the bracket identifier, and determine the bracket locator model based on the bracket locator model identifier.

[0061] Among them, the bracket identifier can uniquely identify a bracket, and the bracket locator model identifier can uniquely identify a bracket locator model.

[0062] Therefore, by querying the preset model database based on the bracket identifier, the corresponding bracket locator model identifier can be obtained, thereby obtaining the bracket locator model corresponding to the bracket locator model identifier.

[0063] Specifically, based on the selected bracket, a matching bracket locator model can be obtained. This means that a subset of teeth can be selected to generate a segmented guide model. For example, Figure 4 A schematic diagram illustrating a model provided in this disclosure embodiment, such as... Figure 4 As shown, teeth 11, 12, and 13 were selected as a group to generate the guide plate model. Figure 4 It includes multiple teeth 10 and corresponding brackets 20, as well as a bracket locator model 30.

[0064] Step 203: Group the teeth to obtain multiple tooth groups. Based on the tooth size, generation direction, bracket locator model, and relative position of the bracket locator model and the corresponding tooth in each tooth group, generate a guide plate model that matches each tooth in the tooth group.

[0065] Specifically, a guide plate model that fits the tooth surface is generated based on the tooth size, growth direction, bracket locator model, and the relative position of the bracket locator model and the corresponding tooth.

[0066] Figure 5a A schematic diagram illustrating another model provided in this disclosure embodiment, such as...Figure 5a As shown in Figure 5a As shown in the figure, all the guide plate models in the box plus the connecting piece are the virtual bracket guide plate 200.

[0067] Step 204, based on the preset connection algorithm, connecting each tooth group corresponding to the guide plate model after the connection operation and the tooth, and determining the virtual bracket guide plate.

[0068] Specifically, after obtaining the guide plate model corresponding to each tooth in each tooth group, the guide plate model is first connected into a whole by a connection algorithm such as Boolean operation algorithm, and then connected with the tooth by a connection algorithm such as Boolean operation algorithm (considering the undercut direction), and finally a virtual bracket guide plate is generated. Thus, the generated virtual bracket guide plate can be used for direct three-dimensional printing as a guide plate.

[0069] Figure 5b As shown in the figure, all the guide plate models in the box plus the connecting piece are the virtual bracket guide plate 200. Figure 5b As shown in Figure 5b As shown in the figure, all the guide plate models in the box plus the connecting piece are the virtual bracket guide plate 200.

[0070] The virtual bracket guide plate generation scheme provided by the embodiment of the present disclosure determines the bracket corresponding to each tooth and the fixed position of the bracket on the tooth based on the pre-designed orthodontic scheme. After the bracket is pasted at the fixed position, the bracket identifier of the bracket is determined, the bracket identifier is queried in the pre-stored model database based on the bracket identifier, the bracket locator model identifier matching the bracket identifier is obtained, the bracket locator model is determined based on the bracket locator model identifier, the teeth are grouped to obtain a plurality of tooth groups, the guide plate model matching each tooth in the tooth group is generated based on the tooth size, the generation direction, the bracket locator model and the relative position of the bracket locator model corresponding to each tooth in each tooth group, and the virtual bracket guide plate is determined after the connection operation of each tooth group corresponding to the guide plate model and the tooth based on the preset connection algorithm. By using the above technical scheme, the virtual bracket guide plate is generated, and then the physical guide plate model can be printed to paste the bracket, which can ensure the accuracy of the position, angle and inclination angle of the bracket, realize accurate bracket positioning, and remove the inaccurate bracket position caused by human habit factors.
