ABSTRACT:
A self-ligating orthodontic bracket has a latch that is movable from a slot-open position to a first closed position or a second closed position. In the first closed position of the latch, the latch engages an archwire with sufficient force to provide active orthodontic therapy. In the second closed position, the effective labial-lingual dimension of the archwire slot is somewhat greater than the overall labial-lingual dimension of the archwire such that the bracket provides passive orthodontic therapy.
