ABSTRACT:
A self-ligating orthodontic bracket for captivating an archwire with a tooth. The bracket includes a bracket body mountable to a tooth and a self-ligating mechanism having an archwire slot and a ligating slide. The ligating slide is movable between an open position in which an archwire is insertable into the archwire slot and a closed position in which the archwire is retained in the archwire slot. The bracket body may be formed from a non-metallic material, such as a polymer, a filled polymer composite, or a ceramic, and the self-ligating mechanism may be formed from a metal. The bracket may include a resilient engagement member with a detent positioned to engage an aperture or throughhole extending through the ligating slide when the ligating slide is in the closed position.
