Abstract: An orthodontic bracket having a base attachable to a tooth surface, with the base extending outward away from the tooth surface and forming an archwire slot sized to receive an archwire therewithin, and a removable archwire slot cover coined onto the base so as to cover the archwire slot and enable the bracket to function as a buccal tube when the cover is attached. The cover may be removed from the bracket base without removal of the bracket from the tooth surface so as to provide an open archwire slot for continued orthodontic treatment subsequent to removal of the removable archwire slot cover.

Abstract: The present invention provides designs for a self-ligating orthodontic bracket. The self-ligating orthodontic bracket includes a mounting base for attachment to a tooth surface, an archwire slot, a rotary ligating cover permitting access to the archwire slot, and one or more locking features for holding the rotary ligating cover in a closed position. In one embodiment, the bracket includes one or more locking tabs on the rotary ligating cover aligned in coplanar relation to and cooperatively mating with cutout portions in the base. In one embodiment, the bracket includes at least one resilient retention mechanism which may include one or more relief channels permitting flexing of at least portions of the rotary ligating cover adjacent to the one or more locking tabs.

Abstract: The present invention provides designs for a self-ligating orthodontic bracket. According to one embodiment, the self-ligating orthodontic bracket includes a mounting base for attachment to a tooth surface, an archwire slot formed upon the base and sized for receiving an orthodontic archwire, a rotary ligating cover selectively rotatable between an open position permitting access to the archwire slot and a closed position covering the archwire slot, and one or more locking features for holding the rotary cover in a closed position. In one embodiment, the bracket includes one or more locking tabs on the rotary cover aligned in coplanar relation to the rotary cover and cooperatively mating with cutout portions in the base. The bracket may include cutouts on the sides of the rotary cover for easier manipulation of the cover. Lead in chamfers on the archwire slot may also be incorporated into the bracket base.
