SELF-LIGATING ORTHODONTIC BRACKET AND DEVICES FOR DEPLOYING SAME

摘要

An orthodontic bracket (10) for coupling an archwire (18) with a tooth includes a bracket body (12) having an archwire slot (16) for receiving the archwire (18) and a movable member (14) engaged with the bracket body (12) and movable between opened and closed positions. The movable member (14) includes a leading edge (118) having a non-uniform pushing element (117a, 1 17e) configured to guide the archwire (18) into the archwire slot (16) as the movable member (14) is closed. An associated method includes providing a movable member (14) for an orthodontic bracket (10) and providing a non-uniform pushing element (117a, 117e) on a leading edge thereof. The pushing element may include a chamfer (117a, 117e) formed along the leading edge of the movable member (14).
