Abstract
The present invention employs a self-ligating orthodontic bracket comprising a body having a pair of laterally spaced gingival tie wings and a pair of laterally spaced occlusal tie wings, the gingival and occlusal tie wings projecting from a labial surface of the body; an arch wire slot extending mesially-distally across the body and between the gingival and occlusal tie wings to accommodate an arch wire; a free-sliding, controlled-locking, or pivoting clip wherein the clip allows placement and removal of the arch wire when in the open position and prevents the displacement of the arch wire from the bracket member when in the closed position.
