SELF-LIGATING ORTHODONTIC BRACKET AND DEVICES FOR DEPLOYING SAME

摘要

An orthodontic bracket (10, 210, 410, 710, 910) for coupling an archwire (18) with a tooth includes a bracket body (12, 212, 412, 712, 912) having an archwire slot (16, 216, 416, 716, 916) adapted to receive the archwire therein and a movable member (14, 214, 414, 714, 914) engaged with the bracket body (12, 212, 412, 712, 912) and movable between an opened position and a closed position. A securing mechanism is configured to secure the movable member (14, 214, 414, 714, 914) in at least the closed position and includes a projecting portion and a receiving portion. The projecting portion may include a generally elongate pin (66, 94, 106, 466, 766, 966) capable of flexing relative to a central axis thereof to secure the movable member (14, 214, 414, 714, 914) in at least the closed position. An orthodontic assembly (650) includes an orthodontic bracket (10) and an alignment device (652) for positioning the bracket on the tooth.
