Tooth correction bracket

Abstract

The invention discloses a tooth correction bracket. The bracket comprises a bracket cover and a bracket body with an arch wire groove and a chute, wherein the bracket cover is a single-sided hook structure, namely the cross section of a draw slip is of an arc shape, the cross section of the chute matched with the draw slip is of an arc shape correspondingly, while a front pterygoid hamulus on the same plane with the draw slip is arranged at the front end outside the other draw slip of the bracket cover; a hinge slot which is matched with the pterygoid hamulus and can perform elastic deformation is arranged at one edge of one side of the chute at the right side of the arch wire groove; the pterygoid hamulus is matched with the hinge slot, so that the arch wire groove can be locked in the bracket cover. According to the tooth correction bracket, the bracket cover is of a single-sided hook, only one pterygoid hamulus is matched with the chute, so that sliding in and out can be facilitated, and the bracket cover can be more freely due to the draw slip and chute with arc-shaped cross sections, and the occurrence of blockage can be prevented.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a bracket for orthodontics. Background technique [0002] At present, in the process of orthodontic treatment of oral teeth, the orthodontic bracket is fixed on the tooth surface, and the arch wire passes through the arch wire slot (also known as the square wire slot) on the bracket, and is bound by a rubber ring or a steel wire. The arch wire is directly tied to the bracket ligation wing, and the correction force of the arch wire is transmitted to the teeth through the bracket, so that the teeth can move as expected, so as to achieve the purpose of correcting the teeth. [0003] Since the currently used ligation rubber ring or ligation steel wire is ligated on the ligation wing of the bracket, it directly exerts force on the arch wire, which produces a large pressure on the arch wire, hinders the normal movement of the arch wire, and thus affects the teeth. orthodontic eff...
