Lingual bracket

Abstract

The invention relates to a lingual bracket. A bracket body consists essentially of a side wing and a bracket seat, wherein the side wing is convexly arranged on an upper surface of the bracket seat, and a lower surface of the bracket seat is provided with anti-skid grains; the lingual bracket is characterized in that: the side wing is arranged by deviating from one end of the bracket seat; a ligature hook is arranged at one side of the side swing positioned at the inner side of the bracket seat, which is toward the middle part; the side wing is arranged in an offset way, thus being capable of vacating an upper space at the other end of the bracket seat, leading the bracket to be capable of being firmly cemented at one end of teeth close to toothcusp, increasing orthodontic force thereof, and also decreasing the influence on chewing as jaw teeth bit the bracket to further reduce the possibility of bracket dropping, and save clinical time. One side wing can be arranged as a replaceable and movable side wing, so that the width of the groove can be adjusted; and the movable side wings with different types can be replaced when in clinical needs, and individualized adjustment can be carried out on the torque angle and protrusion and the like of the teeth.

Description

Technical field: [0001] The invention belongs to the field of medical appliances, in particular to a lingual bracket for correcting teeth. Background technique: [0002] In the existing bracket for orthodontics, the upper surface of the main body is protruded with two side wings for positioning the ligation rubber ring, the lower surface is provided with a bracket seat with anti-slip pattern, and a groove that can accommodate the arch wire is formed between the two side wings Groove, the two wings are symmetrically distributed at both ends of the main body, and its center plane overlaps with the center plane of the bracket seat to form a stable whole. figure 1 It is an existing fixed-wing bracket in which both side wings 1 are integrated with the bracket seat 2, and the width of the groove 3 between the two side wings 1 cannot be adjusted. Invisible lingual orthodontic technology appeared in the 1970s. Because the brackets of the appliance are glued to the lingual side of t...

AI Technical Summary

Problems solved by technology

Traditional lingual brackets use a fixed groove, and the thickness of the bottom of the bracket and the preset torque angle cannot be changed.

This makes the matching degree of brackets and individual teeth very low, and doctors must compensate for this difference by bending orthodontic archwires in a large amount clinically.

Due to reasons such as the lingual view and the small space in the mouth, it is very difficult to achieve a personalized occlusal relationship by bending the arch wire, which also affects the use and clinical promotion of doctors to a large extent, and the medical expenses are also high. Much higher than orthodontic treatment
