ABSTRACT:
A clip for a self-ligating orthodontic bracket assembly has a lifting element between the labial surface of the bracket and the labial portion of the clip that can be rotated to provide a range of adjustability in lifting the labial portion of the clip with respect to the bracket. The lifting element thereby controls the range of motion of the tongue of the clip in its closed position. This limits the forces applied by the clip to an archwire held in the archwire slot of the bracket, and also allows an archwire to slide freely in the slot. A threaded shaft or camming mechanism can be employed as the lifting element.
