Slip cover type dental orthodontic self-locking bracket

Abstract

The invention relates to a dental orthodontic self-locking bracket with a slip cover. The dental orthodontic self-locking bracket comprises a bottom plate and a bracket body with a groove for placing an arch wire, wherein ligation wings are arranged on the two sides of the groove, the slip cover is arranged above the groove, and slip strips are arranged on the two sides of the slip cover; a T-shaped sliding slot is formed on the inner side of the ligation wing on one side of the bracket body and is matched with the slip strips of the slip cover; a guide block and a position-limiting slot are arranged on the lower surface of the slip cover, a guide slot and a salient position-limiting pin are also arranged on the T-shaped sliding slot of the bracket body in a correspondence manner, and by matching, the dental orthodontic self-locking bracket can ensure that the slip cover can form self-locking with the bracket body and can slide back and forth in the position-limiting slot within a limited distance. The dental orthodontic self-locking bracket provided by the invention has the advantages of simple structure and convenience in operation, and can well keep the arch wire in the groove without affecting the normal sliding of the arch wire, greatly shorten the clinical time by reducing the ligation time, and improve and control viral and bacterial infection.

Description

technical field [0001] The invention relates to an appliance for orthodontics, in particular to a bracket for orthodontics. Background technique [0002] At present, the most commonly used method for oral orthodontics is to fix the tooth wires by tying elastic ligature rings or ligature wires around the ligature wings. This method will increase the friction between the tooth wire and the bracket when the tooth wire is kept in the bracket groove, which hinders the normal movement of the arch wire and affects the therapeutic effect of orthodontics. At the same time, during the treatment period, the tooth wire may be changed many times, and the ligature ring or ligature wire must be replaced for each bracket every time, which greatly increases the clinical treatment time. In addition, the elastic ligation ring is easy to spread bacterial diseases and viruses. [0003] Due to these problems, for decades, doctors and bracket manufacturers have developed a large number of bracke...
