[0032] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0034] Figure 1 1 is a flowchart of a method for processing a bracket model provided by an embodiment of the present disclosure, and the method can be executed by an electronic device. The electronic device can be exemplarily understood as a device with a page display function such as a mobile phone, a tablet computer, a laptop computer, a desktop computer, a smart TV, etc. Figure 1 As shown, the method provided in this embodiment includes the following steps:

[0035] S110, obtaining a bracket model and a first coordinate system corresponding to the bracket model, wherein the first coordinate system includes a first origin, a first X-axis, and a first Y-axis, the first origin coincides with the center of the groove bottom plate of the bracket model, the first X-axis is parallel to the short side of the groove bottom plate, and the first Y-axis is perpendicular to the first X-axis.

[0036] Specifically, the bracket model is a three-dimensional model of the bracket, such as a three-dimensional mesh model, but is not limited thereto.

[0037] The bracket model includes a groove bottom plate (i.e., a groove bottom plate plane), and the groove bottom plate is a quadrilateral. For example, when the bracket model is a three-dimensional mesh model, the groove bottom plate is a quadrilateral composed of two triangular mesh facets. The shortest side of the four sides is the short side of the groove bottom plate, and the intersection of the two diagonals in the quadrilateral is the center of the groove bottom plate.

[0038] For example, Figure 2 It is a schematic diagram of a portion of the structure of a bracket model provided in an embodiment of the present disclosure. Figure 3 It is another partial structural schematic diagram of a bracket model provided in an embodiment of the present disclosure. Figure 4 is a schematic diagram of a bracket base plate and a first coordinate provided by an embodiment of the present disclosure. Figure 2 Part of the bracket model shown, Figure 3 Another part of the bracket model shown and Figure 4 The groove bases shown are all from the same bracket model. Figure 2-4 The bracket model includes a groove bottom plate 210, and the groove bottom plate 210 includes four vertices, namely a first vertex 1, a second vertex 2, a third vertex 3 and a fourth vertex 4. The side formed by connecting the first vertex 1 and the second vertex 2 is the short side of the groove bottom plate. The first vertex 1 and the fourth vertex 4 are connected to form a first diagonal line, and the first vertex 2 and the fourth vertex 3 are connected to form a second diagonal line. The intersection of the first diagonal line and the second diagonal line is the center of the groove bottom plate.

[0039] Specifically, the first coordinate system is a coordinate system established based on the bracket model.

[0040] It should be noted that the “first origin coincides with the center of the groove bottom plate of the bracket model” in the first coordinate system means that the first origin completely coincides with the center of the groove bottom plate, or the deviation between the two is less than a preset deviation threshold (which can be set by technicians in this field according to actual conditions), and the “first X-axis is parallel to the short side of the groove bottom plate” means that the first X-axis is completely parallel to the short side of the groove bottom plate, or the angle between the two is less than a preset angle threshold (which can be set by technicians in this field according to actual conditions).

[0041] For example, see Figure 4The first coordinate system includes a first origin O1, a first X-axis, and a first Y-axis. The first origin O1 coincides with the center of the groove bottom plate, the first X-axis is parallel to the short side of the groove bottom plate, and the first Y-axis is perpendicular to the first X-axis.

[0042] S120, obtaining a tooth model, and the tooth long axis and the mesiodistal axis of the tooth model.

[0043] Specifically, the tooth model is a three-dimensional model of a single tooth, such as a point cloud model, a three-dimensional mesh model, etc., but is not limited thereto.

[0044] In some embodiments, S120 may include: acquiring a dental model; and performing tooth segmentation processing on the dental model to obtain a tooth model.

[0045] Specifically, an intraoral scanner may be used to scan the patient's mouth to obtain the dental model, but the invention is not limited thereto.

[0046] Specifically, the teeth segmentation process of the dental model may be performed manually or by artificial intelligence (AI), but is not limited thereto.

[0047] S130, placing the bracket model on one side of the tooth model in a manner such that the first origin is located on the frame axis, the first X-axis and the mesiodistal axis are located in the same plane, and the first Y-axis and the long axis of the tooth are located in the same plane, wherein the frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the long axis of the tooth and the mesiodistal axis.

[0048] Specifically, the bracket placement point is a predetermined point that is located on a straight line with the center of the groove bottom plate of the bracket model when placed.

[0049] Optionally, the bracket placement point of the tooth model is a point in the neighborhood of the clinical crown center point (Facial Axis, FA) of the tooth model. Further optionally, the bracket placement point of the tooth model is the FA point of the tooth model.

[0050] Specifically, the neighborhood of the FA point is the area on the tooth surface including the FA point and located on the buccal side of the tooth model. The specific size of the neighborhood of the FA point can be set by those skilled in the art according to actual conditions and is not limited here.

[0051] Specifically, in S130, the bracket model and the first coordinate system can be temporarily regarded as a whole, so that the first origin is located on the frame axis, the first X-axis and the mesiodistal axis are located in the same plane, and the first Y-axis and the long axis of the tooth are located in the same plane, that is, the center of the groove base plate of the bracket model is located on the frame axis, the short side of the bracket base plate and the mesiodistal axis of the tooth model are located in the same plane, and the line perpendicular to the short side in the bracket base plate and the long axis of the tooth are located in the same plane.

[0052] Specifically, after the bracket model is placed on one side of the tooth model, the bracket model and the bracket placement points of the tooth model are opposite, and then the bracket model is moved closer to the tooth model along the axis of the frame until the bracket model and the tooth model are in contact, so that the bracket model can be placed.

[0053] S140, moving the bracket model along the axis of the frame toward the bracket placement point of the tooth model until the bracket model contacts the tooth model.

[0054] Specifically, during the movement of the bracket model, the posture of the bracket model remains unchanged, that is, the center of the groove base plate of the bracket model is kept on the frame axis, the short side of the bracket base plate and the mesiodistal axis of the tooth model are in the same plane, and the line perpendicular to the short side in the bracket base plate and the long axis of the tooth are in the same plane.

[0055] Specifically, the contact between the bracket model and the tooth model mentioned here means that the area of ​​the contact area between the bracket model and the tooth model is greater than the first preset area threshold, and the specific value of the first preset area threshold can be set by technicians in this field according to actual conditions and is not limited here. For example, the first preset area threshold is 0, but it is not limited thereto.

[0056] For example, Figure 5 is a schematic diagram of a bracket model and a tooth model in contact with each other provided by an embodiment of the present disclosure. Figure 5 , the bracket base of the bracket model is in contact with the tooth model, and the center O1 of the groove base and the bracket placement point BF are in a straight line. In addition, the short side (or the first X-axis) of the bracket base and the mesiodistal axis of the tooth model are in the same plane, and the line perpendicular to the short side in the bracket base and the long axis of the tooth are in the same plane. In this way, when the bracket is placed according to the placement guide of the bracket model on the tooth model, the axial inclination of the bracket can be better expressed on the tooth, so that the bracket can be better stressed and move the tooth, which is conducive to improving the correction effect.

[0057] Optionally, the first coordinate system also includes a first Z axis, which is perpendicular to the groove bottom plate; wherein, after S140, it also includes: performing collision detection adjustment on the bracket model and the tooth model based on the first Z axis to adjust the area of ​​the contact region between the bracket model and the tooth model.

[0058] For example, Figure 6 is a schematic diagram of another bracket base plate and a first coordinate system provided by an embodiment of the present disclosure. Figure 6 The first coordinate system includes a first origin O1, a first X-axis, a first Y-axis, and a first Z-axis. The first origin O1 coincides with the center of the groove bottom plate, the first X-axis is parallel to the short side of the groove bottom plate, the first Y-axis is perpendicular to the first X-axis, and the first Z-axis is perpendicular to the groove bottom plate.

[0059] Specifically, the bracket model is moved along the positive axis of the first Z axis (or the negative axis, or the positive axis first and then the negative axis, or the negative axis first and then the positive axis), and / or the bracket model is rotated around the first Z axis, and in the process of adjusting the bracket model, a collision detection is performed on the bracket model and the tooth model to determine the area of ​​the contact region between the two.

[0060] Specifically, the area of ​​the contact region between the bracket model and the tooth model at the end of the adjustment is greater than or equal to the area of ​​the contact region between the bracket model and the tooth model before the adjustment.

[0061] Optionally, the area of ​​the contact region between the bracket model and the tooth model at the end of the adjustment is the maximum value of the areas of the contact region between the bracket model and the tooth model during the adjustment process. In this way, the area of ​​the contact region can be maximized.

[0062] It is understandable that by performing collision detection adjustment on the bracket model and the tooth model, the contact area between the bracket model and the tooth model can be adjusted to make the contact area larger, which is beneficial to improve the reliability of the bracket when it is attached to the tooth.

[0063] The disclosed embodiment can automatically place the bracket model on the tooth model, and can realize that the center of the groove bottom plate and the bracket model placement point of the tooth model are in a straight line, so that the placement of the bracket model meets clinical requirements. Compared with the prior art that requires doctors to rely on experience to place brackets on teeth, it can reduce the requirements for doctors and improve the efficiency of bracket placement. In addition, the above technical solution can also realize that the short side of the bracket model bottom plate and the mesiodistal axis of the tooth model are in the same plane, and the line perpendicular to the short side in the bracket model bottom plate and the long axis of the tooth of the tooth model are in the same plane. In this way, when the bracket is placed according to the placement guide of the bracket model on the tooth model, the axial inclination angle of the bracket is better expressed on the tooth, so that the bracket is better stressed and thus moves the tooth, which is conducive to improving the correction effect.

[0064] Figure 7 1 is a flow chart of another method for processing a bracket model provided by an embodiment of the present disclosure. The embodiment of the present disclosure is optimized on the basis of the above embodiment, and the embodiment of the present disclosure can be combined with various optional solutions in one or more of the above embodiments.

[0065] like Figure 7 As shown, the verification of the message transmission may include the following steps.

[0066] S710, obtaining a bracket model and a first coordinate system corresponding to the bracket model, wherein the first coordinate system includes a first origin, a first X-axis, and a first Y-axis, the first origin coincides with the center of the groove bottom plate of the bracket model, the first X-axis is parallel to the short side of the groove bottom plate, and the first Y-axis is perpendicular to the first X-axis.

[0067] Specifically, S710 is similar to S110 and will not be described in detail here.

[0068] S720, obtaining a tooth model, and the tooth long axis and the mesiodistal axis of the tooth model.

[0069] Specifically, S720 is similar to S120 and will not be described in detail here.

[0070] S730. Obtain the torque of the bracket model, where the torque corresponds to a rotation angle and a rotation direction.

[0071] Specifically, the torque of the bracket refers to the traction torque and torsional torque generated by the bracket when the bracket is used to correct the teeth. The traction torque refers to the force generated by the tooth moving outward or inward under the action of the bracket; the torsional torque refers to the force of the tooth rotating around the longitudinal axis under the action of the bracket. A positive torque means rotation toward the jaw, and a negative torque means rotation toward the gum.

[0072] S740, rotating the first Y-axis around the first X-axis by a rotation angle based on the rotation direction. Optionally, the first coordinate system further includes a first Z-axis, and the first Z-axis is perpendicular to the groove bottom plate; wherein rotating the first Y-axis around the first X-axis by a rotation angle based on the rotation direction includes: rotating the first Y-axis and the first Z-axis around the first X-axis by a rotation angle based on the rotation direction.

[0073] For example, Figure 8 is a schematic diagram of applying a torque to a bracket model provided by an embodiment of the present disclosure. Figure 8 , rotate the first Y-axis and the first Z-axis around the first X-axis by a preset rotation angle (i.e., the rotation direction corresponding to the torque of the bracket model) based on the clockwise direction (i.e., the rotation direction corresponding to the torque of the bracket model) to change the first coordinate system corresponding to the bracket model.

[0074] S750, placing the bracket model on one side of the tooth model in a manner such that the first origin is located on the frame axis, the first X-axis and the mesiodistal axis are located in the same plane, and the rotated first Y-axis and the long axis of the tooth are located in the same plane, wherein the frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the long axis of the tooth and the mesiodistal axis.

[0075] Specifically, S750 is similar to S130 and will not be described in detail here.

[0076] S760, moving the bracket model along the frame axis toward the bracket placement point of the tooth model until the bracket model contacts the tooth model.

[0077] Specifically, S760 is similar to S140 and will not be described in detail here.

[0078] It can be understood that the first coordinate system corresponding to the bracket model can be changed by rotating the first Y-axis (or the first Y-axis and the first Z-axis) around the first X-axis by a rotation angle based on the rotation direction. In this way, after placing the bracket model on the tooth model based on S750 and S760, the bracket model can be better stressed and thus move the tooth model. In this way, when the bracket is placed according to the placement guide of the bracket model on the tooth model, the bracket can be better stressed and thus move the teeth, thereby making the correction effect more in line with expectations. Optionally, after moving the bracket model along the axis of the frame to the bracket placement point of the tooth model until the bracket model and the tooth model are in contact, it also includes:

[0079] Obtain a second coordinate system corresponding to the bracket model, wherein the second coordinate system includes a second origin, a second X-axis, a second Y-axis, and a second Z-axis, the second origin is the intersection of the rotated first Z-axis and the bracket bottom plate of the bracket model, the second X-axis is parallel to the first X-axis, the second Y-axis is parallel to the rotated first Y-axis, and the second Z-axis is parallel to the rotated first Z-axis;

[0080] The bracket model and the tooth model are subjected to collision detection adjustment based on the second Z axis to adjust the contact area between the bracket model and the tooth model.

[0081] Specifically, the bracket model is moved along the positive axis of the second Z axis (or the negative axis, or the positive axis first and then the negative axis, or the negative axis first and then the positive axis), and / or the bracket model is rotated around the second Z axis, and in the process of adjusting the bracket model, a collision detection is performed on the bracket model and the tooth model to determine the area of ​​the contact region between the two.

[0082] Specifically, the area of ​​the contact region between the bracket model and the tooth model at the end of the adjustment is greater than or equal to the area of ​​the contact region between the bracket model and the tooth model before the adjustment.

[0083] Optionally, the area of ​​the contact region between the bracket model and the tooth model at the end of the adjustment is the maximum value of the areas of the contact region between the bracket model and the tooth model during the adjustment process. In this way, the area of ​​the contact region can be maximized.

[0084] It is understandable that by performing collision detection adjustment on the bracket model and the tooth model, the contact area between the bracket model and the tooth model can be adjusted to make the contact area larger, which is beneficial to improve the reliability of the bracket when it is attached to the tooth.

[0085] The disclosed embodiment can rotate the first coordinate system before placing the bracket model, so that the bracket model can be better stressed and thus move the tooth model. Thus, when the bracket is placed according to the placement instructions of the bracket model on the tooth model, the bracket can be better stressed and thus move the teeth, thereby making the correction effect more in line with expectations.

[0086] It should be noted that the bracket model processing method provided in the present disclosure can be used to design a bracket placement plan for the patient. For example, an intraoral scanner can be used to scan the patient's mouth to obtain a jaw model, and the jaw model can be segmented to obtain multiple tooth models. For each tooth model, the bracket model processing method provided in the present disclosure is used to automatically place the bracket model on the tooth model, such as Fig. 9 As shown. Subsequently, the doctor can stick the bracket on the patient's teeth according to the placement of the bracket model on the tooth model.

[0091] The moving module 1040 is used to move the bracket model along the axis of the frame toward the bracket placement point of the tooth model until the bracket model is in contact with the tooth model.

[0092] In another embodiment of the present disclosure, the first coordinate system further includes a first Z-axis, and the first Z-axis is perpendicular to the groove bottom plate;

[0093] The device further includes: a first collision detection adjustment module, which is used to perform collision detection adjustment on the bracket model and the tooth model based on the first Z axis after the bracket model is moved along the frame axis toward the bracket placement point of the tooth model until the bracket model and the tooth model are in contact, so as to adjust the area of ​​the contact region between the bracket model and the tooth model.

[0094] In another embodiment of the present disclosure, the device further comprises:

[0095] A third acquisition module is used for acquiring a torque of the bracket model before placing the bracket model on one side of the tooth model in a manner that the first origin is located on the frame axis, the first X-axis and the mesiodistal axis are located in the same plane, and the first Y-axis and the tooth long axis are located in the same plane, wherein the torque corresponds to a rotation angle and a rotation direction;
