Orthodontics is to correct teeth, eliminate malocclusion and deformity. Orthodontics mainly studies the etiology and mechanism of malocclusion, diagnosis and analysis, prevention and treatment. Orthodontics can achieve the effect of beautiful teeth.

[0003] The patent document with publication number CN215739555U in the prior art provides an orthodontic bracket, which prolongs the actual length of the archwire between two adjacent brackets by respectively arranging slope sections at both ends of the groove, and can reduce the rigidity of the archwire at the same time, thereby facilitating the reasonable deformation of the archwire. When the archwire passes through the groove and is deformed by the ligation equipment, it is allowed to deform to a certain extent toward the slope section and the bottom of the groove or even fit together, thereby generating a softer force and improving the correction efficiency.

[0027] See also Figure 1-5 ,The utility model provides a technical solution:

[0028] A bracket bonding device comprises a bonding guide plate 1, wherein a plurality of positioning grooves 2 are provided on the inner cavity side wall of the bonding guide plate 1, a bracket seat 3 is clamped inside the positioning groove 2, a limiting component 4 is slidably connected to the top of the bracket seat 3, the limiting component 4 comprises a slide 401, guide grooves 402 are provided on both sides of the inner cavity side walls of the bracket seat 3, a locking piece 403 is slidably connected to the top of the slide 401, guide rails 404 are fixed to both sides of the locking piece 403, a limiting groove 405 is provided on the top of the slide 401, a spring 406 is fixed on the inner cavity side wall of the limiting groove 405, a limiting block 407 fixed to the bottom of the locking piece 403 is fixed at the other end of the spring 406, an archwire groove 5 is provided on the top of the bracket seat 3, a bottom plate 6 is fixed at the bottom of the bracket seat 3, and a positioning component 7 is fixed to the top of the bonding guide plate 1. In the utility model, the medical staff manually pushes the locking piece 403 to disengage the locking piece 403 from the top of the archwire groove 5, puts the archwire into the archwire groove 5, releases the locking piece 403, and the rebound force of the spring 406 drives the limit block 407 to move, thereby driving the locking piece 403 to move and limit the position of the archwire, thereby improving the convenience of the bracket bonding device for fixing the archwire. By scanning the patient's oral cavity, a bonding guide plate 1 matching the patient's teeth is 3D printed, and the bracket seat 3 is clamped into the positioning groove 2, which is convenient for bonding the bracket.

[0029] Specifically, the positioning assembly 7 includes an occlusal cavity 701 provided at the top of the inner cavity of the bonding guide plate 1, elastic sheets 702 are fixedly provided on both sides of the inner cavity of the positioning groove 2, and a clamping groove 703 is provided at the top of the side walls of both sides of the bracket seat 3, and the size and position of the clamping groove 703 match the size and position of the elastic sheet 702. When the bracket bonding device is bitten, the tooth enters the occlusal cavity 701, which is convenient for positioning and bonding the orthodontic bracket. The bottom plate 6 is bonded to the tooth surface by the adhesive, and the adhesive is solidified by local illumination. The elasticity of the elastic sheet 702 itself facilitates the separation from the clamping groove 703, thereby facilitating the direct removal of the bonding guide plate 1 and improving the accuracy of the bracket bonding.

[0030] Furthermore, the length of the limiting groove 405 is greater than the width of the archwire groove 5, and the size and position of the guide groove 402 match the size and position of the guide rail 404. The guide groove 402 and the guide rail 404 with matching sizes can better limit the position of the locking piece 403, thereby limiting the position of the archwire to prevent loosening.

[0031] It is worth noting that the bracket seat 3 and the base plate 6 are made of MIM powder metal, and the four corners of the base plate 6 are arc-shaped. The bracket seat 3 and the base plate 6 cast by MIM powder metal make the surface of the orthodontic bracket smoother, reduce friction, and reduce the incidence of oral ulcers.

[0032] It is worth noting that the cross section of the bottom plate 6 is an arc with an opening downward, and the size and shape of the bottom plate 6 match the size and shape of the mesh surface 8. The bottom plate 6 with an arc cross section makes the orthodontic bracket fit more closely with the teeth.

[0033] In addition, a mesh surface 8 is fixedly arranged at the bottom of the bottom plate 6, and the mesh surface 8 is a honeycomb metal mesh of 80 meshes. The honeycomb metal mesh surface 8 of 80 meshes makes the orthodontic bracket bonding more firmly.

[0034] Working principle: When the device is needed for orthodontic bracket bonding, the medical staff manually pushes the locking piece 403 to disengage the locking piece 403 from the top of the archwire groove 5, puts the archwire into the archwire groove 5, releases the locking piece 403, and the rebound force of the spring 406 drives the limit block 407 to move, thereby driving the locking piece 403 to move and limit the position of the archwire, thereby improving the convenience of the bracket bonding device for archwire fixation, and by scanning the patient's oral cavity to 3D print a bonding guide plate 1 that matches the patient's teeth, the accuracy of bracket bonding is improved, and the bracket is fixed. The seats 3 are respectively snapped into the positioning grooves 2, and the medical staff applies the adhesive on the mesh surface 8 at the bottom of the base plate 6. The 80-mesh honeycomb metal mesh surface 8 makes the orthodontic bracket more firmly bonded. When the patient bites the bracket bonding device, the teeth enter the occlusal cavity 701, which is convenient for positioning and bonding the orthodontic bracket. The base plate 6 is bonded to the surface of the teeth through the adhesive, and the adhesive is solidified by local illumination. The elasticity of the elastic sheet 702 itself makes it easy to detach from the card slot 703, so as to facilitate the direct removal of the bonding guide plate 1, which is convenient for medical staff to operate and saves labor.
