Self-ligating bracket for orthodontics

Abstract

The invention provides a self-ligating bracket for orthodontics. The self-ligating bracket for orthodontics comprises a base part and a cover part, wherein the base part is used for being adhered to the surface of each tooth and comprises a receiving groove used for receiving an orthodontic arch wire, and the receiving groove extends and comprises a bottom wall; the cover part comprises a front edge wall, wherein the front edge wall comprises a middle part and side edge parts positioned o two sides of the middle part; the cover part is connected with the base part in a sliding mode so as to slide between a closed state that the front edge wall is positioned above the bottom wall and an open state that the front edge wall is staggered above the bottom wall; when the cover part is in the closed state the side edge positions of the front edge wall correspond to two ends,along the extending direction, of the bottom wall; and the middle position of the front edge wall corresponds to the middle position of the bottom wall. By use of the technical scheme, the self-ligating bracket for orthodontics is provided, the width of a force bearing point in contact with the orthodontic arch wire during rotation is enough to achieve the effect of moving, twisting and aligning the teeth, and the problem of the width of the force bearing point is solved without ligation by additional ligature wires.

Description

technical field [0001] The invention relates to a self-locking bracket for orthodontics. Background technique [0002] Orthodontic brackets refer to a device made of metal or ceramics fixed on the surface of the teeth with a special adhesive in orthodontic treatment, used to accommodate and fix the orthodontic wire to transmit the orthodontic force to the teeth so that To achieve the purpose of orthodontics, regular follow-up visits are required during the treatment process to replace or adjust the diameter, specification and shape of the orthodontic wire to achieve the goal of orthodontics. At present, there are two types of brackets used in fixed orthodontics on the market: ordinary brackets and self-ligating brackets. The ordinary brackets use ligature wires to fix the orthodontic wires and ordinary brackets, and the ligature wires need to be removed before re-examination. The orthodontic wire needs to be ligated and fixed on the orthodontic bracket after adjustment or r...

AI Technical Summary

Problems solved by technology

[0004] The self-locking structure used in the existing self-locking brackets is relatively complicated. There are a series of locking and fixing structures such as rotating buckles and locking buckles. Compared with ordinary brackets, although it is convenient to use, it needs to Use some special tools, or need small parts such as bolts to cooperate with each other, but the most common self-locking bracket currently used is a slide-button structure, because the design structure of the locking piece in the middle of the bracket causes the width of the locking piece to be affected. limit

[0005] When the orthodontic steel wire moves and rotates in the bracket to align the teeth, the compression force of the locking plate on the orthodontic wire is limited to the teeth transmitted after the bracket body, because the locking plate is only limited by the width in the middle of the bracket, so that The width of the stress point that the orthodontic steel wire contacts during rotation is difficult to move, twist, and align the teeth. In order to increase the control force of tooth movement and rotation during normal use, we have to use the ordinary bracket method to ligate the wire to solve the problem of the width of the stress point.
