Abstract

The invention discloses a passive self-locking bracket, which comprises a bracket body. The middle part of the bracket body is sunken downward to form an archwire slot. A locking piece is arranged above the archwire slot to slide and fit with the bracket body. One of the bracket body and the locking piece is provided with at least one locking position, and one of the bracket body and the locking piece is provided with a fixing mechanism for fixing the locking piece at the locking position. The elastic piece on one of the groove body and the locking piece, the elastic piece has a protrusion that can be received by the locking position, when the locking piece is in the locked state, the protrusion on the elastic piece is locked Stop reception, when the locking piece is in the open state, the protruding end of the elastic member is in close contact with one of the bracket body and the locking piece, forcing the elastic member to contract and store energy . The invention has the advantage of being convenient for arch wire installation.

Description

technical field [0001] The present invention relates to a dental orthodontic appliance, more specifically, it relates to a passive self-locking bracket. Background technique [0002] Orthodontic treatment is a highly specialized branch of the dental field, mainly for the correction of teeth, jaws, and facial deformities, and gradually restores the normal occlusal function of patients by installing fixed orthodontic appliances in the oral cavity. Brackets are an important part of orthodontic appliances. They are mainly bonded to front teeth, canines, and premolars. Orthodontic treatment guides the misaligned teeth to move to the ideal position by installing the orthodontic arch wire in the groove of the bracket. s position. [0003] Ordinary brackets require doctors to re-ligate the arch wires every time they return to the clinic, which will take a lot of time. At the same time, because the arch wires and the bracket body are ligated together, the friction between the arch w...
