ABSTRACT:
A self-locking orthodontic bracket includes a base for attachment to a tooth or tooth band. Transversely spaced tying lugs project from the base and include opposed extensions for orthodontic attachment purposes. The tying lugs present an anterior surface interrupted by an archwire slot. A closure mounted on the bracket includes a movable cover slidably engaging the anterior surface of the bracket. The cover spans the full width of the tying lugs and has a perpendicular width greater than the width of the archwire slot across the anterior surface. The closure is supported on the bracket by a pair of guides that slidably engage opposed side surfaces of the tying lugs for opening and closing the cover. The closure can also be designed to complement the archwire slot structure between the lugs, forming a complete tube encircling the archwire across the full width of the bracket when the cover is in its closed position. The bracket lugs, including the closure, can also be arranged obliquely across a base to provide a tipping angle across the bracket. Bracket placement is facilitated by an encircling shield or cap, including protruding extensions to aid in aligning and locating the bracket on a supporting tooth surface.
