Description

Technical Field

[0001] This application relates to the field of orthodontic technology, and in particular to a bracket adjustment device and a friction measurement system between the archwire and the bracket. Background Technology

[0002] Brackets, made of stainless steel, bioceramics, or composite resin, are directly bonded to the tooth crown surface using adhesives. Archwires are positioned within the grooves of multiple brackets, applying various types of orthodontic forces to the teeth. The primary function of the brackets is to fix the archwire, enabling it to better transmit orthodontic forces and thus control tooth movement in three-dimensional space, achieving the goal of orthodontic treatment. The friction between the archwire and the bracket grooves directly affects the orthodontic forces transmitted by the archwire. Therefore, by simulating the friction between the archwire and bracket grooves, clinical simulations of orthodontics can be optimized, bracket structures improved, and novel bracket materials explored.

[0003] In related technologies, an orthodontic friction force testing system is used to measure the friction force between the archwire and the grooves of multiple brackets. The testing system includes an adjustment device, a traction device, and a data acquisition and processing device. The adjustment device is used to adjust the position of the multiple brackets so that the multiple brackets are aligned in a straight line; the traction device is used to pull the archwire to slide back and forth in the grooves of the multiple brackets; and the data acquisition and processing device is used to obtain the friction force values ​​between the archwire and the multiple brackets.

[0048] As explained in the background section, the orthodontic friction testing system in the related technology has a technical problem in that it cannot simulate the actual alignment of teeth. This problem arises because, due to limitations such as experimental conditions and uncertainties in the patient's intraoral condition, the testing methods for friction between orthodontic brackets and archwires in the related technology are usually in vitro experiments. In vitro friction testing includes two forms: friction testing between a single bracket and archwire, and friction testing between a group of brackets (two or more) and archwires. In the friction testing between a single bracket and archwire, the movement between the bracket and archwire includes: the bracket is fixed during the test, and the archwire is pulled by an external force, causing the archwire to slide along the bracket groove; or the archwire is fixed during the test, and the bracket slides along the archwire under the action of an external force. In the friction testing between a group of brackets (two or more) and archwires, the movement between the bracket and archwire includes: the bracket is fixed during the test, and the archwire is pulled by an external force, causing the archwire to slide along the bracket groove. Compared to the friction test between a single bracket and the archwire, the friction test between a group of brackets (two or more) and the archwire is more complex and closer to the actual clinical situation.

[0049] For testing the frictional force between a group of brackets (two or more) and the archwire, the orthodontic frictional force testing system includes: a bracket and archwire adjustment device, an archwire traction device, and a data acquisition and processing device. The bracket and archwire adjustment device aligns and fixes a group of brackets on the same plane, while controlling the position of the archwire clamp to ensure that the archwire and bracket grooves are perfectly aligned initially and remain parallel. The archwire traction device then allows the archwire to slide along the bracket grooves. Simultaneously, the data acquisition and processing device calculates the actual magnitude of the frictional force, thereby analyzing the influence of different experimental materials, different brackets, different archwire sizes, different ligation methods, and other factors on the frictional force, as well as the changes in frictional force within the system.

[0050] However, although the above-mentioned orthodontic friction testing system can study the friction of two or more brackets, it cannot simulate the arrangement of real teeth because the brackets are arranged in a straight line.

[0051] To address the aforementioned technical problems, this application provides a bracket adjustment device and a friction measurement system between the archwire and the bracket. The rotation mechanism of the bracket adjustment device can drive the bracket clamp to undergo angular displacement around a first directional axis and a second directional axis, and can also drive the bracket clamp to rotate around a third directional axis, wherein the first directional axis, the second directional axis, and the third directional axis are perpendicular to each other. The moving mechanism of the bracket adjustment device can drive the bracket clamp to move along the X, Y, and Z directions, thereby adjusting the bracket arrangement, the tilt angle between the bracket and the archwire, and the torque angle between the bracket and the archwire, so that the bracket and the archwire have sufficient degrees of freedom to simulate the arrangement of real teeth, thereby better simulating and guiding orthodontic clinical practice.

[0052] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

All three components are connected to the bracket clamp 100. The X-axis moving component 301 is used to drive the bracket clamp 100 along the X-direction (…). Figure 1 The X-axis moving component 302 is used to drive the tray clamp 100 along the Y-axis (as shown in the X-axis direction) to move linearly, and the Y-axis moving component 302 is used to drive the tray clamp 100 along the Y-axis (as shown in the X-axis direction) to move linearly. Figure 1 The Y-axis moving component 303 is used to drive the tray clamp 100 along the Z-axis (as shown in the diagram) to move linearly, and the Z-axis moving component 303 is used to drive the tray clamp 100 along the Z-axis (as shown in the diagram) to move linearly.

The X-axis moving component 301, Y-axis moving component 302, and Z-axis moving component 303 of its first moving mechanism 300 are also connected to the bracket clamp 100. The first angular component 201 causes the bracket clamp 100 to undergo angular displacement around a first azimuth axis, the second angular component 202 causes the bracket clamp 100 to undergo angular displacement around a second azimuth axis, and the rotation component 203 causes the bracket clamp 100 to rotate around a third azimuth axis. The first azimuth axis, the second azimuth axis, and the third azimuth axis are perpendicular to each other. The X-axis moving component 301 causes the bracket clamp 100 to move along the X direction, the Y-axis moving component 302 causes the bracket clamp 100 to move along the Y direction, and the Z-axis moving component 303 causes the bracket clamp 100 to move along the Z direction. This allows the bracket clamp 100 to move linearly along the X, Y, and Z directions, thereby adjusting its fixed position. It also allows the bracket clamp 100 to undergo angular displacement around the first and second orientation axes, and to rotate around the third orientation axis, thereby adjusting its fixed angle. This achieves the purpose of adjusting the arrangement of the brackets, the tilt angle between the brackets and the archwire, and the torque angle between the brackets and the archwire, giving the brackets and archwire sufficient degrees of freedom to simulate the arrangement of real teeth, thus better simulating and guiding orthodontic clinical practice.

The first corner component 201 is connected to the bracket clamp 100, and the second corner component 202 is connected to both the rotating component 203 and the first corner component 201. The rotating component 203 rotates around the third orientation axis and drives the second corner component 202 to rotate. The second corner component 202 rotates around the second orientation axis (parallel to the paper shown). Figure 1 The second arc surface 2021 shown in the figure undergoes angular displacement, which in turn causes the first angular component 201 to undergo angular displacement. The first angular component 201 rotates around the first azimuth axis ( Figure 1 The first arc surface 2011 shown in the figure undergoes angular displacement, which in turn causes the bracket clamp 100 to undergo angular displacement. This achieves the connection between the first angular positioning component 201, the second angular positioning component 202, and the rotating component 203 and the bracket clamp 100, while improving the overall structural compactness and measurement accuracy.

Figure 1 The X-axis moving component 301 (shown in the Z direction) moves and drives the rotating component 203 of the first rotating mechanism 200 to move. Simultaneously, the rotating component 203 moves the first angular component 201 and the second angular component 202.

The friction measurement system for archwire and brackets in this application transforms the research object of bracket and archwire friction testing from a single bracket to the entire orthodontic system. Multiple bracket adjustment devices A can adjust the arrangement of the brackets 400, enabling them to achieve six degrees of freedom of movement, while the archwire 500 can achieve four degrees of freedom. Adjustment can also make the grooves of the brackets 400 parallel to the archwire 500, or form a certain tilt angle or torque angle. This allows for the study of friction and critical angles between the brackets 400 and archwire 500 in a two-dimensional plane, as well as in three-dimensional space. Multiple bracket clamps 100 can simulate both crowding and malocclusion of the dentition, as well as tooth tilting and torsion. Different arrangements and combinations can simulate various clinical tooth morphologies, thus better simulating orthodontic clinical practice and providing better simulation and guidance for orthodontic treatment.

[0069] Furthermore, the measuring and data processing devices can also feed back the friction data during the test to the terminal equipment, making it easier for technicians to analyze.

[0071] One end of the bowwire 500 can be fixed, while the other end is held by the bowwire clamp 701. When the first translation stage 7031 moves the bowwire clamp 701 along the X direction ( Figure 6 When the first translation stage 7031 moves in the X direction (as shown in the diagram), it can provide traction in the X direction to the other end of the bowwire 500.

[0072] Alternatively, both ends of the bowwire 500 are held by bowwire clamps 701. When the two first translation stages 7031 respectively drive the bowwire clamps 701 along the X direction ( Figure 6 When the two first translation stages 7031 move in opposite directions (as shown in the X direction), both first translation stages 7031 can provide traction force along the X direction to the bowwire 500.

[0084] In summary, this application provides a bracket adjustment device and a friction measurement system for the archwire and bracket. The first angular component 201, the second angular component 202, and the rotation component 203 of the first rotation mechanism 200 of the bracket adjustment device are all connected to the bracket clamp 100. The X-axis movement component 301, the Y-axis movement component 302, and the Z-axis movement component 303 of its first moving mechanism 300 are all connected to the bracket clamp 100. The first angular component 201 drives the bracket clamp 100 to rotate around the first... An angular displacement occurs on the azimuth axis, causing the second angular component 202 to drive the tray clamp 100 to undergo angular displacement around the second azimuth axis, and the rotation component 203 to drive the tray clamp 100 to rotate around the third azimuth axis; wherein, the first azimuth axis, the second azimuth axis, and the third azimuth axis are perpendicular to each other; the X-axis moving component 301 drives the tray clamp 100 to move along the X direction, the Y-axis moving component 302 drives the tray clamp 100 to move along the Y direction, and the Z-axis moving component 303 drives the tray clamp 100 to move along the Z direction. This allows the bracket clamp 100 to move linearly along the X, Y, and Z directions, thereby adjusting its fixed position. It also allows the bracket clamp 100 to undergo angular displacement around the first and second orientation axes, and to rotate around the third orientation axis, thereby adjusting its fixed angle. This achieves the purpose of adjusting the arrangement of the brackets, the tilt angle between the brackets and the archwire, and the torque angle between the brackets and the archwire, giving the brackets and archwire sufficient degrees of freedom to simulate the arrangement of real teeth, thus better simulating and guiding orthodontic clinical practice.
