Abstract
A cap is releasably connected to an orthodontic bracket and covers tips of occlusal bracket tiewings in order to prevent contact of the bracket with the enamel of opposing dentition. The cap includes a section that extends at least partially along a channel of the bracket extending in a generally occlusal-gingival direction in order to help retain the cap in its intended position and prevent the cap from rotating relative to the bracket. In preferred embodiments, the cap is made of a stain-resistant aesthetically pleasing material. Optionally, the cap serves as a ligature in order to retain an archwire in an archwire slot of the bracket.
