Description

Technical Field

[0001] The utility model relates to the technical field of tooth orthodontics, and more specifically to an orthodontic bracket. Background Art

[0002] Dental correction covers a wide range, usually referring to the treatment process of correcting uneven teeth, abnormal tooth shape, and abnormal tooth color through oral technical means. 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.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the arch wire needs to be manually tied into the groove for connection, which is not convenient to use; secondly, the lack of a traction hook makes the fixation effect of the arch wire poor, which needs to be improved. In view of this, we propose an orthodontic bracket. Utility Model Content

[0028] An orthodontic bracket comprises a base plate 1, a bracket seat 2 is fixedly arranged on the top of the base plate 1, an archwire groove 3 is provided on the top of the bracket seat 2, a limiting component 4 is slidably connected to the top of the bracket seat 2, 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 2, a locking piece 403 is slidably connected to the top of the slide 401, guide rails 404 are fixedly arranged on both sides of the side walls of the locking piece 403, the guide groove 402 is slidably connected to the guide rail 404, a limiting groove 405 is provided on the top of the slide 401, a spring 406 is fixedly arranged on the bottom of the inner cavity of the limiting groove 405, a limiting block 407 is fixedly arranged on the top of the spring 406, a positioning groove 408 is provided on the top of the locking piece 403, a traction hook component 5 is threadedly connected to the side wall of the bracket seat 2, and a mesh surface 6 is fixedly arranged at the bottom of the base plate 1. The utility model fixes the base plate 1 on the surface of the tooth that needs orthodontics through the mesh surface 6, presses the limit block 407 through the medical tool, slides the locking plate 403 outward, puts the archwire into the archwire groove 3, pushes the locking plate 403 inward, and the rebound force of the spring 406 drives the limit block 407 to enter the positioning groove 408, thereby improving the convenience of fixing the orthodontic bracket archwire.

[0029] Specifically, the traction hook assembly 5 includes a ball head 501, a connecting rod 502 is fixedly arranged on one side of the circumferential outer wall of the ball head 501, a screw 503 is fixedly arranged on the other end of the connecting rod 502, and the screw 503 is threadedly connected with a screw hole provided on the side wall of the bracket seat 2. The traction hook assembly 5 is connected to the bracket seat 2 through the screw 503. When the arch wire needs to be reinforced, the screw 503 is screwed in along the thread direction, the arch wire is wound and fixed on the circumferential outer wall of the connecting rod 502, and the position of the arch wire is limited by the ball head 501 to prevent it from falling off.

[0030] Furthermore, the locking piece 403 is located at the top of the archwire groove 3, and the size and position of the limit block 407 match the size and position of the positioning groove 408. The position of the locking piece 403 is better limited by the limit block 407 and the positioning groove 408 of matching size to prevent loosening.

[0031] It is worth noting that the base plate 1 and the bracket seat 2 are made of MIM powder metal, and the four corners of the base plate 1 are arc-shaped. The base plate 1 and the bracket seat 2 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 1 is an arc with an opening downward, and the size and shape of the mesh surface 6 match the size and shape of the bottom plate 1. The bottom plate 1 with an arc cross section makes the orthodontic bracket fit more closely with the teeth.

[0033] In addition, the mesh surface 6 is a honeycomb metal mesh with a mesh size of 80 meshes, and tooth position marks are laser-etched on the mesh surface 6. The honeycomb metal mesh surface 6 with a mesh size of 80 meshes makes the orthodontic bracket bonding more secure, and the tooth position marks laser-etched facilitate clear identification of tooth positions.

[0034] Working principle: When the device is needed for orthodontic treatment, the base plate 1 is fixed on the surface of the tooth that needs orthodontic treatment. The base plate 1 with an arc-shaped cross section makes the orthodontic bracket fit more closely with the tooth. The honeycomb metal mesh surface 6 with a mesh size of 80 makes the orthodontic bracket bond more firmly. The limit block 407 is pressed by a medical tool, the locking piece 403 is slid outward, the archwire is placed in the archwire groove 3, the locking piece 403 is pushed inward, and the rebound force of the spring 406 drives the limit block 407 to enter the positioning groove 408. The position of the locking piece 403 is better limited to prevent loosening, and the convenience of fixing the orthodontic bracket archwire is improved. The traction hook assembly 5 is connected to the bracket seat 2 through the screw 503. When the archwire needs to be reinforced, the screw 503 is screwed in along the thread direction, and the archwire is wound and fixed on the circumferential outer wall of the connecting rod 502. The position of the archwire is limited by the ball head 501 to prevent it from falling off. The base plate 1 and the bracket seat 2 cast by MIM powder metal make the surface of the orthodontic bracket smoother, reduce friction, and reduce the incidence of oral ulcers.
