Orthodontic self-locking bracket convenient to clean

Abstract

The invention discloses an orthodontic self-locking bracket convenient to clean. The bracket includes a bracket body, a groove body and a lock cover; an arch wire groove is arranged in the bracket body, two side walls of the arch wire groove are recessed inwards to form insertion grooves conveniently inserted into the groove body in side directions, the middle part of the arch wire groove is provided with a limiting groove, the arch wire groove and the limiting groove divide the bracket body into four ligation wings, the position, close to the upper end, of the inner wall of each ligation wingis symmetrically provided with a positioning rotating hole or a positioning locking hole, and the lower end of the bracket body is provided with strip-shaped grooves side by side; and the groove bodyincludes a groove-shaped plate, the middle parts of two side plates of the groove-shaped plate are symmetrically provided with rectangular open holes, and the bottom end of each rectangular open holeis connected to a limiting plate. According to the bracket, the groove body convenient to assemble and disassemble is arranged in the bracket body, the groove body is used to replace the bracket bodyto support an arch wire, so that the wear resistance is greatly improved; and at the same time, the lock cover makes the bracket has the advantage of a self-locking bracket, accessories such as ligature wires and rubber bands are not needed, so that the hygienic cleaning of an oral cavity is facilitated, and the correction effect is more stable.

Description

technical field [0001] The invention relates to the technical field of orthodontic appliances, in particular to a convenient and clean orthodontic self-locking bracket. Background technique [0002] In recent years, with the popularization and promotion of orthodontics, more and more people have received orthodontic treatment, which has also promoted the rapid development of the orthodontic manufacturing industry. Alignment, especially for orthodontic brackets. Orthodontic brackets include ordinary brackets and self-ligating brackets. Since ordinary brackets are mainly ligated with stainless steel wires or rubber rings, these two kinds of ligations are directly applied to the dental arch wires, which have a large impact on the arch wires and brackets. Friction and arch wire cannot slide freely in the bracket, which greatly prolongs the treatment period, so now major manufacturers are vigorously developing self-ligating brackets, which have the advantages of simple operation...
