The bracket is an important component of the orthodontic appliance and is mainly adhered to anterior teeth, canine teeth and premolar, and orthodontic treatment guides malposed teeth to move to an ideal position by installing an orthodontic arch wire in a groove of the bracket. The traditional bracket adopts a ligature wire or an elastic rubber ring to ligate to fix the orthodontic arch wire in the groove, but the fixing mode has the defects of time and inconvenience for clinical operation, large friction force, poor comfort degree and the like.

In recent years, the advent of self-ligating bracket (self-ligating bracket) correction systems has introduced new approaches to the orthodontic treatment of malocclusions. The biggest characteristic of the self-locking bracket is that the self-locking structure of the bracket replaces the traditional ligature wire (ring) to ligate the arch wire, thereby reducing the friction force in the orthodontic appliance, obviously increasing the orthodontic efficiency, and being a quick, comfortable and safe fixed correction device.
