[0038] The present invention provides a high-precision dental appliance and its production method as shown in Figure 1 and includes the following steps:

[0039] S1. Structure design: Design a metal bracket orthodontic appliance according to the biological principle of tooth movement. The biological principle of tooth movement is mainly based on the plasticity of the alveolar bone and the response of the periodontal tissue. The alveolar bone is the most metabolically active and remodeled part of the human skeleton, with the ability of proliferation and absorption. This dynamic balance is the biological basis of orthodontic treatment. The bracket 302 needs to balance strength and dimensional accuracy to ensure precise force application when cooperating with the arch wire;

[0040] S2. Mold forming: Use the casting process to manufacture the mold. Determine the shape of the bracket 302 using a wax pattern, replicate the precise structure through a replica molding technique, perform high-temperature firing after embedding and replica molding, and remove the wax pattern to form a casting cavity;

[0041] S3. Metal casting: Inject molten medical stainless steel into the casting cavity of the mold, and form an orthodontic appliance blank after cooling. The temperature needs to be controlled during the casting process to avoid bubbles. Usually, the model needs to be soaked to eliminate the interference of bubbles;

[0042] S4. Fine trimming: Use a deburring device to perform deburring operations on the orthodontic appliance blank, and at the same time use a numerical control machine tool to process the groove details of the orthodontic appliance.

[0043] S5. Polishing and passivation: Reduce the surface roughness of the orthodontic appliance through electrolytic polishing, and perform passivation treatment on it to enhance the corrosion resistance of the orthodontic appliance. Furthermore, it can reduce the erosion of the oral environment on the metal and extend the service life of the orthodontic appliance body 3.

[0044] S6. Function detection: Detect the fit between the orthodontic appliance and the arch wire to verify whether the orthodontic appliance meets the design requirements. At the same time, it is necessary to check the flatness of the bonding surface of the bracket base 301 to ensure the stability of clinical bonding.

[0045] The deburring device in S4 includes a device body 1. At both ends of the inner bottom of the device body 1, clamping mechanisms 2 are provided. At both ends of one side of the inner wall of the device body 1, grinding mechanisms 4 are provided. Through the clamping mechanism 2, the orthodontic appliance body 3 can be clamped and fixed, and then through the grinding mechanism 4, the outer wall of the orthodontic appliance body 3 can be ground and deburred, thereby ensuring the smoothness of the outer wall of the orthodontic appliance body 3.

[0046] For the convenience of clamping the orthodontic appliance body 3 and replacing the outer wall for grinding, as Figures 2 - 4 and Figure 6 shown, the clamping mechanism 2 includes a placement plate 201. Inside the placement plate 201, a bidirectional lead screw 203 is provided. On the outer sides of both ends of the bidirectional lead screw 203, movable plates 205 are threadedly sleeved. On the inner walls of the tops of the two movable plates 205, rotating shafts 206 are rotatably installed. At the adjacent ends of the two rotating shafts 206, clamping plates 208 are fixedly installed. The orthodontic appliance body 3 is clamped between the two clamping plates 208. By the operation of the first motor 204, the bidirectional lead screw 203 rotates. Through the threaded connection between the bidirectional lead screw 203 and the inner wall of the bottom of the movable plate 205, the two movable plates 205 can move relative to or away from each other on the outer wall of the bidirectional lead screw 203, thereby adjusting the distance between the two clamping plates 208, so that the two clamping plates 208 can clamp and fix the orthodontic appliance body 3. By the operation of the second motor 207, the adjacent rotating shaft 206 can be driven to rotate, thereby driving the clamping plate 208 to rotate, and further driving the orthodontic appliance body 3 to rotate, so as to replace and adjust the outer wall of the orthodontic appliance body 3 that needs to be ground.

[0047] For the convenience of performing grinding and deburring operations on the outer wall of the orthodontic appliance body 3, as Figures 2 - 4 and Figure 7As shown in the figure, the grinding mechanism 4 includes an adjusting screw rod 401. An activity seat 403 is sleeved on the outer side of the adjusting screw rod 401 through threads. At the top of the side of the activity seat 403 away from the inner wall of the device body 1, a hydraulic cylinder 404 is fixedly installed. The piston rod of the hydraulic cylinder 404 is fixedly installed with a fixed seat 405. On the outer wall of the side of the fixed seat 405 away from the activity seat 403, an electric cylinder 406 is fixedly installed. The piston rod of the electric cylinder 406 is fixedly installed with a mounting plate 407. A grinding file 408 is rotatably installed inside the mounting plate 407. When the third motor 402 works, the adjacent adjusting screw rods 401 rotate, causing the activity seat 403 to move on its outer side. Thus, the height of the grinding file 408 can be adjusted to lower it to the position of the outer wall of the corrector body 3. Then, when the electric cylinder 406 extends, it can drive the mounting plate 407 to move, enabling the grinding file 408 to contact the outer wall of the corrector body 3. Then, when the driving motor 409 works, the grinding file 408 rotates, and thus the outer wall of the corrector body 3 can be ground and deburred. At the same time, when the hydraulic cylinder 404 extends and contracts, it can drive the fixed seat 405 to move up and down, enabling the grinding file 408 to perform grinding and deburring operations on different positions of one side outer wall of the corrector body 3.

[0048] For the convenient control of the operation of the device, such as Figures 2 - 3 and Figure 5 As shown in the figure, the device body 1 includes an operation table 101. On the outer wall of one side of the operation table 101, a control box 102 is fixedly installed. The two ends of the top of the operation table 101 are respectively fixedly connected to two placement plates 201. On one side of the top of the operation table 101, a fixed frame 103 is fixedly installed. Activity slots 104 are opened on the inner walls at both ends of the vertical part of the fixed frame 103. The inner walls of the activity slots 104 are rotatably connected to the adjacent adjusting screw rods 401. At both ends of the top of the fixed frame 103, third motors 402 are fixedly installed. The third motors 402 are connected to the adjacent adjusting screw rods 401 through output shafts for transmission. The operation table 101 can install and fix the two placement plates 201. The adjusting screw rods 401 can be installed and fixed through the activity slots 104 on the inner walls of the fixed frame 103. Through the control box 102, the operations of the clamping mechanism 2 and the grinding mechanism 4 can be controlled.

[0049] In order to enable the clamping mechanism 2 to stably clamp and fix the corrector body 3, such as Figures 3 - 4 and Figure 6As shown, a mounting groove 202 is provided on the inner wall of the top of the placement plate 201, and the inner wall of the mounting groove 202 is rotatably connected to the adjacent bidirectional screw rod 203. A first motor 204 is fixedly installed on the outer wall of one end of the placement plate 201, and the first motor 204 is connected to the adjacent bidirectional screw rod 203 through an output shaft transmission connection. A second motor 207 is fixedly installed on the outer wall of one end of one of the movable plates 205 at the same end, and the second motor 207 is connected to the adjacent rotating shaft 206 through an output shaft transmission connection. A rubber pad is fixedly installed on the contact portion between the clamping plate 208 and the corrector body 3, and the mounting groove 202 can install and fix the bidirectional screw rod 203. At the same time, the mounting groove 2 02 The movement of the movable plate 205 can be limited so that the movable plate 205 remains stable during the movement. One of the movable plates 205 can install and fix the second motor 207. The operation of the second motor 207 causes the adjacent rotating shaft 206 to rotate, thereby driving the adjacent clamping plate 208 to rotate. Through the contact between the rubber pad and the corrector body 3, the other clamping plate 208 and the rotating shaft 206 rotate accordingly, and then the outer wall of the corrector body 3 toward the grinding mechanism 4 can be replaced and adjusted, so that the grinding mechanism 4 can conveniently grind and deburr different outer walls of the corrector body 3.

[0050] In order to provide power for the rotation of the grinding file 408, as Figures 3 - 4 and Figure 7 As shown, a driving motor 409 is fixedly installed on the outer wall of one end of the mounting plate 407, and the driving motor 409 and the grinding file 408 are connected via an output shaft transmission. The mounting plate 407 can install and fix the driving motor 409, and the driving motor 409 can drive the grinding file 408 to rotate, so that the grinding file 408 can grind and deburr the outer wall of the corrector body 3 on one side facing the grinding mechanism 4.

[0051] A high-precision brace processed by the production method, the corrector body 3 includes a bracket base plate 301, a bracket 302 is fixedly installed on the outer wall of one end of the bracket base plate 301, and connected grooves 303 are opened on the inner walls on both sides of the bracket 302. A clamping groove 304 is opened at the bottom of the inner wall of one end of the bracket 302 away from the bracket base plate 301.

[0052] In order to keep the archwire stable inside the bracket 302, Figure 8 As shown, a sealing plate 305 is rotatably installed on the top of the inner wall of one end of the bracket 302 away from the bracket base plate 301, and a plug-in plate 306 is fixedly installed on the bottom of the sealing plate 305. The plug-in plate 306 is movably connected to the inner wall of the snap-in groove 304. Through the connection between the plug-in plate 306 and the snap-in groove 304, the sealing plate 305 can seal the inner wall of the side of the bracket 302 away from the bracket base plate 301, and then the arch wire inside the groove 303 can be pressed and fixed, so that the corrector body 3 is tightly connected to the arch wire.

[0053] The implementation method is specifically as follows: When deburring the blank of the orthosis formed by cooling the mold, place the orthosis body 3 to be processed on the top of the clamping mechanism 2. The first motor 204 can be controlled to work through the control box 102, and then the adjacent bidirectional lead screw 203 can be driven to rotate. Through the threaded connection between the bidirectional lead screw 203 and the inner wall of the movable plate 205, the two movable plates 205 move relative to or away from each other along the inner wall of the mounting groove 202 on the outer wall of the bidirectional lead screw 203, and then the distance between the two clamping plates 208 can be adjusted, so that the two clamping plates 208 can clamp and fix the orthosis body 3, making one outer wall of the orthosis body 3 face the grinding mechanism 4. Then, the third motor 402 is made to work through the control box 102, and then the adjacent adjusting lead screw 401 can be driven to rotate. Through the threaded connection between the adjusting lead screw 401 and the inner wall of the movable seat 403, the movable seat 403 moves along the inner wall of the adjacent movable groove 104 on the outside of the adjusting lead screw 401, and then the height of the grinding file 408 can be adjusted, so that the grinding file 408 can descend to the position of one outer wall of the orthosis body 3;

[0054] The electric cylinder 406 is extended through the control box 102 to drive the mounting plate 407 to move, and then the longitudinal position of the grinding file 408 can be adjusted to make it contact with one outer wall of the orthosis body 3. Then, the drive motor 409 is made to rotate through the control box 102, and then the grinding file 408 can be driven to rotate, and then one outer wall of the orthosis body 3 can be ground. Furthermore, the hydraulic cylinder 404 is extended or contracted through the control box 102 to drive the grinding file 408 to move up and down reciprocally, and then deburring operations can be performed on different positions of one outer wall of the orthosis body 3. After one outer wall is ground, the second motor 207 is made to work through the control box 102, and then the adjacent rotating shaft 206 can be driven to rotate, and then the adjacent clamping plates 208 can be driven to rotate. Through the connection between the clamping plates 208 and the orthosis body 3, the orthosis body 3 rotates accordingly, and then the outer wall of the orthosis body 3 facing the grinding mechanism 4 can be replaced. Furthermore, by repeating the above operations, deburring operations can be performed on different outer walls of the orthosis body 3, and then the production efficiency of the orthosis can be improved. This implementation method specifically solves the problem in the prior art that the position of the orthosis cannot be conveniently adjusted, resulting in the deburring device being unable to conveniently perform deburring operations on different positions of the outer wall of the orthosis, leading to low production efficiency of the orthosis.
