Description

Technical Field

[0001] The invention relates to the field of orthodontic guide plate manufacturing, and in particular to a method for manufacturing a guide plate used for orthodontic treatment. Background Art

[0002] Bracket correction is a relatively common method of tooth correction. It mainly involves sticking brackets on the teeth and using archwires to apply force to gradually move the teeth to the ideal position. The bracket sticking position is a critical step in tooth correction. In actual operation, the bracket sticking position can be located using a guide plate that fits the teeth. Teeth have different shapes and sizes and are irregular in shape, so it is difficult to make a guide plate that accurately positions the bracket.

[0003] To this end, the patent publication number CN109620435B discloses a method for manufacturing a bracket positioning guide, wherein the bracket positioning guide comprises a hard pressed film for occlusion, a soft pressed film for fitting the tooth surface, and a bubble ball, wherein the hard pressed film and the soft pressed film have the same appearance, and the hard pressed film and the soft pressed film are completely fitted, and the hard pressed film and the soft pressed film are provided with mounting grooves for mounting brackets and completely matching the brackets, and the bubble ball is arranged at the edge of the bottom of the mounting groove. The bracket positioning guide provided by the present invention arranges bubble balls at the edge of the bottom of the mounting groove for mounting the bracket, and when the bracket is installed, the bubble balls are located at the edge of the bracket, and excess adhesive can flow into the bubble balls for storage, thereby avoiding the difficulty of cleaning after the excess adhesive overflows the bottom plate, and at the same time avoiding the generation of obstructive force on the bracket positioning guide.

[0004] After the guide plate is formed through 3D printing, it still needs to be cleaned, sprayed, cooled and other processes. The guide plate structure is small and the wall thickness is thin. It is easy to be deformed by physical pressure during the subsequent processing, resulting in a decrease in the adaptability of the prepared guide plate to the teeth, and the inability to accurately locate the bonding position of the bracket. The deformed guide plate may even be unable to be installed on the teeth. In addition, the factors of guide plate processing deformation are also affected by the processing time. Too long processing time will increase the time the guide plate is subjected to force, which is more likely to cause deformation in the guide plate preparation. Summary of the invention

[0005] In view of the above problems, a method for manufacturing a guide plate for orthodontic treatment is provided. The shaping frame installed on the outside of the correction guide plate in combination solves the problem that the guide plate needs to be cleaned, sprayed, cooled and other processes after being formed by 3D printing. The guide plate has a small structure and a thin wall. It is easily deformed by physical pressure during subsequent processing, resulting in a reduced fit between the prepared guide plate and the teeth, and the bracket bonding position cannot be accurately located. There may even be problems such as the deformed guide plate being unable to be installed on the teeth.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, a shaping frame is provided to protect the outside of the correction guide. After the correction guide is manufactured by a 3D printer, a corresponding shaping frame is manufactured according to the shape of the correction guide. The shaping frame is made of hard material and is snap-fitted and installed on the outside of the correction guide. When the correction guide is cleaned and sprayed, the shaping frame can effectively avoid deformation during processing of the correction guide under the protective effect of the shaping frame, thereby improving the precision of the preparation of the correction guide and its compatibility with the tooth assembly.

The present invention is provided with an assembly component to install the combined shaping frame and correction guide plate on the supporting component, and an internal threaded column is fixed on the shaping frame, and the internal threaded column is threadedly assembled on the threaded rod of the movable frame.

At the same time, the shaping frame and the correction guide plate reciprocate under the transmission action of the steering drive rod assembly. The shaping frame and the correction guide plate move regularly and multi-directionally in the ultrasonic cleaning machine, increasing the coverage area of ​​the liquid on their surface, so that more microbubbles can contact the surface of the correction guide plate, thereby improving the cleaning efficiency of the correction guide plate, shortening the cleaning time, and further avoiding the deformation of the correction guide plate during processing.

[0043] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] See also Figure 1-Figure 9 As shown, a method for manufacturing a guide plate for orthodontic treatment comprises the following steps:

[0045] S1. Scan and obtain the three-dimensional data of the teeth, select the appropriate reference teeth, locate the pasting position of other correction components that need to be corrected according to the position of the reference teeth, and design a three-dimensional model of the guide plate that meets the correction teeth based on the pasting position and the three-dimensional data of each tooth.

[0046] S2. A guide plate for the teeth to be corrected is made by a 3D printer, and a protective structure adapted to the guide plate is prepared according to its shape. The subsequent guide plate processing and the protective structure are combined with each other to prevent the guide plate from being deformed during processing and affecting its adaptability to the teeth.

[0047] S3. Clean and disinfect the prepared guide plate using a cleaning device to remove residual substances on the guide plate.

[0048] S4. Use spraying equipment to spray the cleaned guide plate to increase the durability and corrosion resistance of the guide plate.

[0049] S5. Cool the guide plate to maintain its shape, and install the prepared guide plate on the tooth model to test its fit.

[0050] S2 adopts a protective structure, which is snap-fitted and assembled on the outside of the correction guide 1. A limiting module 11 is fixed on the correction guide 1. The correction guide 1 is assembled on the teeth. The bracket 2 is snap-fitted with the limiting module 11 to limit the position of the bracket 2 attached to the teeth. The protective structure includes a shaping frame 3 adapted to the correction guide 1 to prevent the guide from being deformed during processing; S3 adopts a cleaning device, which includes an ultrasonic cleaning machine 4. The ultrasonic cleaning machine 4 is equipped with a support component 5 for assisting the correction guide 1 in deep cleaning and preventing the correction guide 1 from being deformed during processing. The correction guide 1 and the shaping frame 3 are assembled in combination on the support component 5; S4 adopts a spraying device, which includes a spraying machine 6. The spraying machine 6 is equipped with a support component 5 for assisting the correction guide 1 in all-round spraying and preventing the correction guide 1 from being deformed during processing. The support component 5 can be installed in the ultrasonic cleaning machine 4 and the spraying machine 6 for use, and has a wide range of applications.

[0051] According to the three-dimensional tooth model, the corresponding position of the bracket 2 on the tooth to be corrected is located, and the correction guide 1 for each tooth to be corrected is prepared based on the position of the bracket 2. Then, the corresponding shaping frame 3 is prepared according to the shape of the correction guide 1. When the correction guide 1 is subsequently cleaned and sprayed, the shaping frame 3 is clamped on one side of the correction guide 1. The shaping frame 3 has a high hardness and can maintain the shape of the correction guide 1 to avoid deformation of the correction guide 1 during processing.

[0052] When the correction guide plate 1 is being cleaned and sprayed, the support assembly 5 is assembled and set in the ultrasonic cleaning machine 4 or the spraying machine 6. The support assembly 5 can limit the cleaning and spraying position of the correction guide plate 1, and the cleaning and spraying angle of the correction guide plate 1 can be controlled by the support assembly 5, thereby assisting the correction guide plate 1 in deep cleaning and comprehensive spraying, improving the cleaning and spraying efficiency, shortening the processing time, and thus avoiding deformation of the correction guide plate 1 during long-term cleaning and spraying processing.

[0053] See also Figure 1-Figure 6 As shown, two embedded grooves 31 are symmetrically provided on the shaping frame 3 about the center axis, and a through groove 33 is provided in the middle position of the shaping frame 3. The through groove 33 and the two embedded grooves 31 are mutually connected, and the inner diameter of the through groove 33 is smaller than the inner diameter of the embedded groove 31; the shaping frame 3 is clamped on the outside of the correction guide 1 through the embedded groove 31; a clamping groove 32 is provided on the side of the shaping frame 3, and the shaping frame 3 is clamped on the outside of the limit module 11 through the clamping groove 32. The shaping frame 3 is made of high hardness material, and the shape of the embedded groove 31 provided on the inner side is adapted to the external shape of the correction guide 1.

[0054] After the correction guide 1 is printed and formed by a 3D printer, a shaping frame 3 is prepared according to the shape of the correction guide 1, and the correction guide 1 is snap-fitted and installed in the embedded groove 31 on the shaping frame 3. After the shaping frame 3 is combined with the correction guide 1, the outside of the correction guide 1 is protected, and the correction guide 1 can be shaped and supported to prevent the correction guide 1 from deformation. During the subsequent cleaning and spraying processing, the correction guide 1 is always combined with the shaping frame 3 to complete the processing. Under the shaping support of the shaping frame 3, the correction guide 1 is highly likely to be avoided from being deformed during the processing, thereby improving the processing quality of the correction guide 1 and maintaining the degree of compatibility between the processed correction guide 1 and the tooth assembly.

[0055] See also Figure 3 As shown, the depth of the embedded groove 31 on the shaping frame 3 is less than half the thickness of the correction guide plate 1, and the two embedded grooves 31 symmetrically opened on the shaping frame 3 have the same depth.

[0056] The shaping frame 3 is snap-fitted and installed on one side of the correction guide 1, with more than half of the correction guide 1 exposed to the outside, so that it can be cleaned and sprayed in the ultrasonic cleaning machine 4 and the sprayer 6. After processing one side of the correction guide 1, the correction guide 1 is snap-fitted and installed in the embedded groove 31 on the other side of the shaping frame 3. The combined shaping frame 3 and the correction guide 1 are assembled in the support assembly 5. With the assistance of the support assembly 5, the cleaning and spraying operations on the other side are completed again. A through groove 33 is provided between the two embedded grooves 31 in the shaping frame 3. The setting of the through groove 33 facilitates the wave transmission of water flow in the shaping frame 3 during the cleaning process, thereby avoiding dirt from remaining in the shaping frame 3.

[0057] See also Figure 6 As shown, the inner walls of the two embedded grooves 31 of the shaping frame 3 are both installed with soft films 34 that dampen and limit the snap-fit ​​assembly position of the correction guide plate 1. The thickness of the soft film 34 is moderate, which can not only keep the correction guide plate 1 stably assembled in the shaping frame 3, but also prevent the correction guide plate 1 from being elastically deformed when assembled inside the shaping frame 3 due to the adjustable range of the soft film 34.

[0058] A soft film 34 is installed on the inner wall of the embedded groove 31 opened on the shaping frame 3. When the correction guide 1 is snap-fitted and installed in the embedded groove 31, the correction guide 1 squeezes the soft film 34. Under the action of the squeezing force, the correction guide 1 can be more stably assembled in the shaping frame 3. At the same time, due to the extrudable flexible characteristics of the soft film 34, local deformation of the correction guide 1 is avoided when the correction guide 1 and the shaping frame 3 are combined.

[0059] See also Figure 7-Figure 11 As shown, the support assembly 5 includes a triangular support frame 51 supporting the ultrasonic cleaning machine 4, and a clamping rod 52 mounted on the side wall of the ultrasonic cleaning machine 4, the clamping rod 52 penetrates and is slidably connected to the triangular support frame 51, a lifting frame 53 is slidably mounted on the triangular support frame 51, a slide groove 54 is provided on the lifting frame 53, a slide seat 55 is slidably mounted in the slide groove 54, and a moving frame 56 is fixedly mounted on the slide seat 55; an assembly assembly 57 for assembling a combined structure of the correction guide plate 1 and the shaping frame 3 is installed on the moving frame 56; a linkage assembly 58 for synchronously driving the lifting frame 53 and the moving frame 56 is installed on the triangular support frame 51; the clamping rod 52 is connected to the upper part of the triangular support frame 51 in a damping sliding manner, and the position of the clamping rod 52 is adjusted by moving up and down. The moving position of the clamping rod 52 can be quickly limited by the damping characteristics, which is convenient for adjustment operation.

[0060] When cleaning the correction guide 1, the triangular support frame 51 in the support assembly 5 is supported in the internal cleaning frame of the ultrasonic cleaning machine 4, and the two sets of clamping rods 52 above the triangular support frame 51 are stretched and moved, and the elastic clips on the clamping rods 52 are engaged and restricted on the side wall of the cleaning frame, so that the support assembly 5 is quickly installed and restricted in the ultrasonic cleaning machine 4.

[0061] The combined correction guide plate 1 and shaping frame 3 are installed on the moving frame 56 through the assembly component 57, and the positions of the multiple correction guide plates 1 and the shaping frame 3 corresponding to the ultrasonic cleaning machine 4 are limited to avoid the collision of the multiple correction guide plates 1 with the water flow during the cleaning process, thereby reducing the probability of the correction guide plates 1 being deformed during cleaning. At the same time, during the cleaning process, the lifting frame 53 is controlled to engage with the triangular support frame 51 and move back and forth longitudinally. When the lifting frame 53 moves, the moving frame 56 is controlled by the linkage component 58 connected between the triangular support frame 51 and the moving frame 56. Corresponding to the lateral reciprocating movement in the lifting frame 53, the slide seat 55 fixed on the side of the movable frame 56 passes through the slide groove 54 and slides horizontally. Through this part of the mechanical transmission structure, the combined shaping frame 3 and the correction guide plate 1 can be moved in the ultrasonic cleaning machine 4 in the up, down, left and right directions, increasing the coverage area of ​​the liquid on its surface, so that more microbubbles can contact the surface of the correction guide plate 1, so that the correction guide plate 1 can quickly complete the cleaning operation, shorten the cleaning processing time of the correction guide plate 1, and avoid deformation of the correction guide plate 1 during a long cleaning process.

[0062] See also Fig. 9 and Fig.10 As shown, the assembly component 57 includes a threaded rod 571 rotatably mounted on the mobile frame 56 and an internal threaded column 572 fixedly mounted on the shaping frame 3 , and the threaded rod 571 and the internal threaded column 572 are threadedly assembled.

[0063] An internal thread column 572 is fixedly installed on each shaping frame 3, and the combined shaping frame 3 and the correction guide plate 1 are threadedly transferred to the bottom of the threaded rod 571 through the internal thread column 572, so as to limit the correction guide plate 1 to the cleaning processing position corresponding to the ultrasonic cleaning machine 4, so as to avoid the correction guide plate 1 from irregularly moving and colliding with each other during processing to cause deformation.

[0064] See also Figure 9-12 As shown, a servo motor 511 is fixedly mounted on the triangular support frame 51 , an output end of the servo motor 511 is connected to a lead screw 512 , an internal threaded adjustment rod 513 is threadedly mounted on the lead screw 512 , and the internal threaded adjustment rod 513 is fixedly mounted on the lifting frame 53 .

[0065] The servo motor 511 is operated to control the reciprocating rotation of the lead screw 512. The lead screw 512 is threadedly assembled with the internal thread adjustment rod 513. Under the action of the threaded transmission structure, the internal thread adjustment rod 513 moves reciprocatingly up and down. The internal thread adjustment rod 513 is fixedly installed on the lifting frame 53, which controls the lifting frame 53 to move reciprocatingly up and down synchronously, and adjusts the correction guide plate 1 to correspond to the processing position in the ultrasonic cleaning machine 4.

[0066] See also Figure 9-12As shown, the linkage assembly 58 includes a fixed block 581 fixed on the triangular support frame 51 , a push rod 582 is rotatably mounted on the fixed block 581 , and the push rod 582 is rotatably assembled with the slide seat 55 .

[0067] During the up and down reciprocating movement of the lifting frame 53, the mobile frame 56 assembled on the upper side for horizontal sliding movement is driven to move up and down synchronously. The two ends of the push rod 582 connected between the slide 55 and the triangular support frame 51 rotate accordingly. The rotating push rod 582 pushes the slide 55 to engage in the slide groove 54 for horizontal reciprocating movement. The slide 55 and the mobile frame 56 are fixedly assembled, so that the lifting frame 53 can be controlled to move horizontally in the process of longitudinal reciprocating movement, so that the correction guide plate 1 and the shaping frame 3 assembled on the mobile frame 56 can move regularly in the up, down, left and right directions, thereby improving the cleaning processing effect of the correction guide plate 1 placed in the ultrasonic cleaning machine 4.

[0068] See also Figure 10-Figure 14 As shown, a steering drive assembly 59 is installed on the movable frame 56 and is linked to control the reciprocating rotation of the threaded rod 571.

[0069] The threaded rod 571 is controlled to reciprocate on the movable frame 56 through the steering drive assembly 59, so that the correction guide plate 1 and the shaping frame 3 installed on the threaded rod 571 rotate reciprocatingly, and the correction guide plate 1 is fully in contact with the cleaning liquid in the ultrasonic cleaning machine 4, further improving its cleaning processing effect.

[0070] See also Figure 10-Figure 14 As shown, the steering drive assembly 59 includes a gear block 591 fixed on the threaded rod 571 , and a rack 592 is meshedly assembled on the side of the gear block 591 , and the rack 592 is fixedly assembled with the lifting frame 53 .

[0071] When the movable frame 56 moves back and forth left and right on the lifting frame 53, the tooth block 591 on the movable frame 56 moves laterally on the side of the rack 592. The tooth block 591 is meshed and assembled with the rack 592. Under the action of the meshing transmission structure, the tooth block 591 can be controlled to rotate back and forth. The tooth block 591 is fixedly installed above the threaded rod 571. The rotation of the tooth block 591 drives the threaded rod 571 to rotate synchronously. The threaded rod 571 drives the combined shaping frame 3 and the correction guide plate 1 below to rotate back and forth, thereby improving the effect of ultrasonic cleaning of the correction guide plate 1, shortening the cleaning processing time and avoiding processing deformation of the correction guide plate 1.

[0072] See also Figure 8-Figure 14As shown, after the cleaning process is completed, the correction guide plate 1 needs to be sprayed. The support component 5 is installed on the spray machine 6 through the triangular support frame 51, and the positions of the shaping frames 3 and the correction guide plate 1 on the support component 5 correspond to the positions of the spray ports on the spray machine 6. During the spraying process, the lifting frame 53 is controlled to move back and forth up and down, and the lifting frame 53 controls the movable frame 56 to move back and forth horizontally through the linkage component 58. During the horizontal movement of the movable frame 56, the steering drive component 59 controls the internal threaded rod 571 and the combined shaping frame 3 and the correction guide plate 1 to reciprocate. The correction guide plate 1 performs regular movements up, down, left and right under the driving action of this part. At the same time, the correction guide plate 1 performs reciprocating rotation during the regular movement. The correction guide plate 1 has more movement directions and can complete the spraying process more comprehensively to avoid the generation of processing dead angles.

[0073] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
