<p>A self-ligating orthodontic bracket for captivating an archwire with a tooth. The bracket (10, 110) includes a bracket body (12, 112) mountable to a tooth and a self-ligating mechanism (14, 114) having an archwire slot (38, 138) and a ligating slide (16, 116). The ligating slide (16, 116) is movable between an open position in which an archwire is insertable into the archwire slot (38, 138) and a closed position in which the archwire is retained in the archwire slot (38, 138). The bracket body (12, 112) may be formed from a non-metallic material, such as a polymer, a filled polymer composite, or a ceramic, and the self-ligating mechanism (14, 114) may be formed from a metal. The bracket (10, 110) may include a resilient engagement member (18, 118) with a detent (46, 176) positioned to engage an aperture or throughhole (58, 152) extending through the ligating slide (16, 116) when the ligating slide (16, 116) is in the closed position. <IMAGE></p> |
