[0001] This disclosure relates to the field of computer technology, and in particular to a method, apparatus, device, and storage medium for processing a bracket model. Background Technology

[0002] Orthodontics is the process of straightening teeth and correcting malocclusions and deformities. Currently, the main method used in the market is to use bracket braces for orthodontic treatment. Specifically, brackets are directly bonded to the teeth with adhesive, and archwires apply various types of corrective forces through the brackets to control the three-dimensional movement of the teeth, thereby achieving the purpose of orthodontic treatment.

[0003] Currently, bracket placement on teeth relies primarily on the dentist's experience, which is demanding and time-consuming. Therefore, a convenient and efficient bracket placement method is urgently needed. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, the present disclosure provides a method, apparatus, device and storage medium for processing a bracket model.

[0005] A first aspect of this disclosure provides a method for processing a bracket model, the method comprising:

[0006] Obtain a bracket model and a first coordinate system corresponding to the bracket model. 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.

[0007] Obtain a tooth model, and the long axis and mesiodistal axis of the tooth model;

[0008] The bracket model is placed on one side of the tooth model with the first origin located on the frame axis, the first X-axis and the mesiodistal axis in the same plane, and the first Y-axis and the tooth length axis in the same plane. The frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the tooth length axis and the mesiodistal axis.

[0009] Move 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 make contact.

[0010] A second aspect of this disclosure provides a processing apparatus for a bracket model, the apparatus comprising:

[0011] The first acquisition module is used to acquire the bracket model and the first coordinate system corresponding to the bracket model. 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.

[0012] The second acquisition module is used to acquire the tooth model, as well as the long axis and mesiodistal axis of the tooth model;

[0013] The placement module is used to place the bracket model on one side of the tooth model in such a way that the first origin is located on the frame axis, the first X-axis is in the same plane as the mesiodistal axis, and the first Y-axis is in the same plane as the tooth length axis. The frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the tooth length axis and the mesiodistal axis.

[0014] The moving module is used to move 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 make contact.

[0015] A third aspect of this disclosure provides an electronic device, the server comprising: a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor performs the method of the first aspect described above.

[0016] A fourth aspect of this disclosure provides a computer-readable storage medium storing a computer program that, when executed by a processor, can implement the method of the first aspect described above.

[0017] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0018] This embodiment of the disclosure can obtain a bracket model and a first coordinate system corresponding to the bracket model. 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 base plate of the bracket model. The first X-axis is parallel to the short side of the groove base plate, and the first Y-axis is perpendicular to the first X-axis. A tooth model and the tooth long axis and mesiodistal axis of the tooth model are obtained. The bracket model is placed on one side of the tooth model with the first origin located on the frame axis, the first X-axis and the mesiodistal axis in the same plane, and the first Y-axis and the tooth long axis in the same plane. The frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the tooth long axis and the mesiodistal axis. The bracket model is moved along the frame axis to the bracket placement point of the tooth model until the bracket model and the tooth model come into contact. As can be seen, the above-mentioned technical solution can automatically place the bracket model onto the dental model, and ensure that the center of the groove base plate and the bracket placement point on the dental model are aligned on a straight line. This ensures that the bracket placement meets clinical requirements, reducing the demands on the dentist and improving placement efficiency compared to existing technologies that require experience. Furthermore, this technical solution also ensures that the short side of the bracket base plate is in the same plane as the mesial and distal axes of the dental model, and that the line perpendicular to the short side of the bracket base plate is in the same plane as the long axis of the tooth. This allows for better representation of the bracket's axial tilt on the tooth when placement is performed according to the guide on the dental model, resulting in better force distribution and tooth movement, thus improving orthodontic outcomes.

[0032] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0033] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

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

[0035] S110. Obtain the bracket model and the first coordinate system corresponding to the bracket model. 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 to this.

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

[0038] For example, Figure 2 This is a partial structural schematic diagram of a bracket model provided in an embodiment of this disclosure. Figure 3 This is another structural schematic diagram of a bracket model provided in an embodiment of this disclosure. Figure 4 This is a schematic diagram of a bracket base plate and a first coordinate system provided in an embodiment of this disclosure. Figure 2 The partial bracket model shown Figure 3 The other part of the bracket model shown and Figure 4 The trench base plates shown are all derived from the same support model. See also Figure 2-4 The groove model includes a groove base plate 210, which has four vertices: first vertex 1, second vertex 2, third vertex 3, and fourth vertex 4. The side formed by connecting first vertex 1 and second vertex 2 is the short side of the groove base plate. First vertex 1 and fourth vertex 4 are connected to form the first diagonal, and first vertex 2 and fourth vertex 3 are connected to form the second diagonal. The intersection of the first diagonal and the second diagonal is the center of the groove base plate.

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

[0040] It should be noted that, regarding the "first origin coinciding with the center of the trench bottom plate of the trough model" in the first coordinate system, it means that the first origin and the center of the trench bottom plate are completely coincident, or the deviation between them is less than a preset deviation threshold (which can be set by those skilled in the art according to the actual situation). The "first X-axis parallel to the short side of the trench bottom plate" means that the first X-axis is completely parallel to the short side of the trench bottom plate, or the included angle between them is less than a preset included angle threshold (which can be set by those skilled in the art according to the actual situation).

[0041] For example, see [link to example]. 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 trench bottom plate, the first X-axis is parallel to the short side of the trench bottom plate, and the first Y-axis is perpendicular to the first X-axis.

[0042] S120, Obtain a tooth model, and the long axis and 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 or a three-dimensional mesh model, but it is not limited to these.

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

[0045] Specifically, an intraoral scanner can be used to scan the patient's mouth to obtain a dental model, but it is not limited to this.

[0046] Specifically, tooth segmentation can be performed on dental models using manual or artificial intelligence (AI) methods, but it is not limited to these methods.

[0047] S130. The bracket model is placed on one side of the tooth model in such a way that the first origin is located on the frame axis, the first X-axis is in the same plane as the mesial and distal axes, and the first Y-axis is in the same plane as the tooth length axis. The frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the tooth length axis and the mesial and distal axes.

[0048] Specifically, the bracket placement point is a pre-determined point that is aligned with the center of the groove bottom plate of the bracket model during placement.

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

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

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

[0052] Specifically, after placing the bracket model on one side of the tooth model, with the bracket placement points of the bracket model and the tooth model facing each other, the bracket model is then moved closer to the tooth model along the bracket axis until the bracket model and the tooth model come into contact, thus achieving the placement of the bracket model.

[0053] S140. Move the bracket model along the axis of the bracket on the tooth model until the bracket model and the tooth model come into contact.

[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 located on the frame axis, the short side of the bracket base plate is in the same plane as the mesial and distal axes of the tooth model, and the line in the bracket base plate perpendicular to the short side is in the same plane as the long axis of the tooth.

[0055] Specifically, the contact between the bracket model and the tooth model mentioned here refers to the contact area between the bracket model and the tooth model being greater than a first preset area threshold. The specific value of the first preset area threshold can be set by those skilled in the art according to the actual situation, and is not limited here. For example, the first preset area threshold is 0, but it is not limited to this.

[0056] For example, Figure 5 This is a schematic diagram showing a bracket model and a tooth model in contact, according to an embodiment of this disclosure. See also... Figure 5 The bracket base of the bracket model contacts the tooth model, with the center O1 of the base and the bracket placement point BF aligned on a straight line. Furthermore, the short side (or the first X-axis) of the bracket base lies in the same plane as the mesial and distal axes of the tooth model, and the line perpendicular to the short side of the bracket base lies in the same plane as the long axis of the tooth. This allows for better bracket placement according to the guide on the tooth model, resulting in a more accurate representation of the bracket's axial tilt on the tooth. This facilitates better force distribution on the bracket, thereby moving the tooth and improving the orthodontic effect.

[0057] Optionally, the first coordinate system further includes a first Z-axis, which is perpendicular to the groove bottom plate; wherein, after S140, the system further 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 area between the bracket model and the tooth model.

[0058] For example, Figure 6 This is a schematic diagram of another bracket base plate and a first coordinate system provided in an embodiment of this disclosure. See also... 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 trench bottom plate. The first X-axis is parallel to the short side of the trench bottom plate. The first Y-axis is perpendicular to the first X-axis. The first Z-axis is perpendicular to the trench bottom plate.

[0059] Specifically, the bracket model is moved along the positive axis (or negative axis, or positive axis followed by negative axis, or negative axis followed by positive axis) of the first Z-axis, and / or the bracket model is rotated around the first Z-axis. During the adjustment of the bracket model, collision detection is performed on the bracket model and the tooth model to determine the area of ​​their contact area.

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

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

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

[0063] This embodiment of the invention can automatically place the bracket model onto the dental model, ensuring that the center of the groove base plate and the bracket placement point on the dental model are aligned. This allows the bracket placement to meet clinical requirements, reducing the demands on the dentist and improving placement efficiency compared to existing technologies that require experience. Furthermore, the above technical solution ensures that the short side of the bracket base plate is in the same plane as the mesial and distal axes of the dental model, and that the line perpendicular to the short side of the bracket base plate is in the same plane as the long axis of the tooth. This allows for better bracket placement according to the guide on the dental model, resulting in a better representation of the bracket's axial tilt on the tooth, improving force distribution and tooth movement, and ultimately enhancing the orthodontic effect.

[0064] Figure 7 This is a flowchart illustrating another method for processing a bracket model provided in this disclosure. This disclosure optimizes the above embodiments and can be combined with various optional solutions from one or more of the above embodiments.

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

[0066] S710. Obtain the bracket model and the first coordinate system corresponding to the bracket model. 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, acquire a tooth model, and the long axis and mesiodistal axis of the tooth model.

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

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

[0071] Specifically, bracket torque refers to the traction torque and torsional torque generated by the brackets when orthodontic treatment is performed. Traction torque is the force exerted by the brackets to move the teeth outwards or inwards; torsional torque is the force exerted by the brackets to rotate the teeth around their longitudinal axis. Positive torque indicates rotation in the occlusal direction, while negative torque indicates rotation in the gingival direction.

[0072] S740. Rotate 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, which is perpendicular to the trench 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 This is a schematic diagram illustrating the application of torque to a bracket model according to an embodiment of this disclosure. See also... Figure 8 The first Y-axis and the first Z-axis are rotated around the first X-axis by a preset rotation angle (i.e., the rotation direction corresponding to the torque of the bracket model) in a 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. The bracket model is placed on one side of the tooth model in such a way that the first origin is located on the frame axis, the first X-axis is in the same plane as the mesial and distal axes, and the rotated first Y-axis is in the same plane as the tooth length axis. The frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the tooth length axis and the mesial and distal axes.

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

[0076] S760. Move 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 come into contact.

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

[0078] It is understandable that 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 can change the first coordinate system corresponding to the bracket model. Thus, after placing the bracket model onto the tooth model based on S750 and S760, the bracket model can better receive force and move the tooth model. Therefore, when placing the bracket according to the placement guide on the tooth model, the bracket can better receive force and move the tooth, resulting in a more satisfactory orthodontic effect. Optionally, after moving the bracket model along the bracket axis to the bracket placement point on the tooth model until the bracket model and the tooth model contact, the following steps are also included:

[0079] Obtain the second coordinate system corresponding to the bracket model. 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 base 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] Collision detection and adjustment are performed on the bracket model and tooth model based on the second Z-axis to adjust the area of ​​the contact region between the bracket model and the tooth model.

[0081] Specifically, the bracket model is moved along the positive axis (or negative axis, or positive axis first then negative axis, or negative axis first then positive axis) of the second Z-axis, and / or the bracket model is rotated around the second Z-axis. During the adjustment of the bracket model, collision detection is performed on the bracket model and the tooth model to determine the area of ​​their contact area.

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

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

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

[0085] In this embodiment of the present disclosure, the bracket model can be rotated before placement, which allows the bracket model to 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 tooth, thereby making the orthodontic effect more in line with expectations.

[0086] It should be noted that the bracket model processing method provided in this disclosure can be used to design bracket placement schemes for patients. For example, an intraoral scanner can be used to scan the patient's mouth to obtain a dental model, and the dental model can be segmented to obtain multiple tooth models. For each tooth model, the bracket model is automatically placed on the tooth model using the bracket model processing method provided in this disclosure, such as... Figure 9 As shown. Subsequently, the dentist can attach the brackets to the patient's teeth based on how the bracket model is positioned on the dental model.

[0087] Figure 10 This is a schematic diagram of a processing device for a bracket model provided in an embodiment of this disclosure. This processing device for the bracket model can be understood as the aforementioned electronic device or a functional module within the aforementioned electronic device. For example...

The frame axis passes through the bracket placement point of the tooth model and is perpendicular to both the tooth length axis and the mesiodistal axis.

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

[0094] In yet another embodiment of this disclosure, the device further includes:

The torque corresponds to the rotation angle and the rotation direction.

[0096] A rotation module is used to rotate the first Y-axis around the first X-axis by the rotation angle based on the rotation direction;

[0097] Specifically, the placement module 1030 is used to place the bracket model on one side of the tooth model in such a way that the first origin is located on the frame axis, the first X-axis and the mesial-distal axis are in the same plane, and the rotated first Y-axis and the tooth length axis are in the same plane.

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 base 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.

[0102] The second collision detection and adjustment module is used to perform collision detection and adjustment on the bracket model and the tooth model based on the second Z-axis, so as to adjust the area of ​​the contact area between the bracket model and the tooth model.
