Abstract
An orthodontic bracket is described and which includes a base member defining an archwire slot having an opening, and at least one projection extending outwardly from the base member; a ligating slide moveable between a first position which is clear of the archwire slot, and second position where the ligating slide projects over the opening of the archwire slot; and a biasing member borne by the ligating slide, and resiliently cooperating with the projection, and wherein the biasing member has a first portion which receives the projection when the ligating slide is in the first position, and a second portion which receives the projection when the ligating slide is in the second position.
Claims13
An orthodontic bracket for coupling an archwire with a tooth, comprising:
- a bracket body that is configured to be mounted to the tooth and that includes an archwire slot adapted to receive the archwire, an anterior surface, a slide channel, and a recess that is formed in the anterior surface;
- a ligating slide that includes a superior end and is movable relative to the bracket body in the slide channel between an opened position and a closed position;
- a resilient member;
- and
- a projection that cooperates with the resilient member to releasably restrain the heating slide in the closed position,
- wherein during movement of the ligating slide toward the opened position, the projection cooperates with the resilient member to produce a force in a perpendicular direction relative to the projection,
- wherein the recess includes a wall that opposes the superior end of the ligating slide in the closed position and receives a tool to contact the superior end of the ligating slide so as to move the ligating slide toward the opened position.
