An orthodontic self-ligating bracket system with an open auxiliary groove

Abstract

The invention relates to an orthodontic self-locking bracket system with open auxiliary grooves, comprising a plurality of brackets, the brackets are provided with inner main grooves and auxiliary grooves, and an elastic The baffle plate and the bracket are provided with the first bracket, the second bracket and the third bracket, and the two ends of the elastic baffle of the first bracket are flush with the two side walls of the first bracket; One end of the elastic baffle is flush with the side wall of the second bracket, and the other end forms a unilateral gap with the side wall of the second bracket; the two ends of the elastic baffle of the third bracket are symmetrically arranged with double side notch. In the present invention, the first bracket is installed on the incisors, the second bracket is installed on the canines, and the third bracket is installed on the premolars, and the elastic baffles of the first bracket, the second bracket and the third bracket are cleverly used Set, so that the arch wire of the bracket system produces different correction forces at the positions corresponding to different brackets.

Description

An orthodontic self-locking bracket system with open auxiliary grooves technical field The present invention relates to the field of dental orthodontic equipment, in particular to a kind of orthodontic self-locking bracket system with open auxiliary grooves system. Background technique [0002] In orthodontic treatment, selective extraction of teeth is often required to provide space, and the space obtained is used to relieve the dental arch. crowding or for adduction of protruding incisors. For most cases where extractions are necessary, the most commonly extracted teeth are the front Molars, because the extraction of premolars has the least impact on the morphology and function of the dental arch, and the correction of malocclusion is of great significance. The orthodontic brackets are bonded on the labial side of the remaining teeth after the premolars are extracted, and a plurality of orthodontic brackets are connected by using an arch wire. Orthodontic force is...

AI Technical Summary

Problems solved by technology

However, when the rocker-shaped archwire is seated in the groove of the orthodontic bracket, excessive friction will be generated between the rocking chair deformation of the archwire and the corresponding groove of the orthodontic bracket. To overcome the above-mentioned friction force, it is necessary to increase the Large orthodontic force, but excessive orthodontic force will not only increase periodontal damage, but also cause displacement of other teeth that do not want to move

[0007] At present, the above-mentioned problems objectively exist in the field of orthodontics. In order to solve the above-mentioned problems, doctors can only adjust the bonding position of the orthodontic brackets, the degree of bending adjustment of the arch wire, and the magnitude of the orthodontic force based on personal experience. It is difficult to achieve precise, safe and efficient control of tooth movement, which increases the risk, time and economic cost of patients
