Abstract
A self-locking orthodontic bracket includes a supporting base and transversely spaced tying lugs interrupted by a transverse archwire slot. A closure mounted on the bracket includes a movable cover slidably overlapping an anterior surface across the bracket. The closure is supported by sliding guides that engage opposed side surfaces of the tying lugs. A transverse flat spring is recessed within the fixed wall to selectively engage indented areas on the posterior surface of the cover and serve as a detent. The detent selectively positions the cover in an open or closed position relative to the archwire slot. The brackets are preferably installed in two sets for attachment to the upper and lower teeth with the covers of both sets being movable to their open positions in common inferior directions. This facilitates visualization of the open archwire slot and adjacent bracket surfaces by attending professionals.
