Abstract
A hand instrument for debonding an adhesively bonded orthodontic bracket from a patient's tooth includes two jaws, each of which includes a contact pad for engaging opposite sides of the bracket. When the jaws are moved together, at least a majority of the area of each contact pad that contacts the side of the bracket is located beneath the archwire slot of the bracket in a lingual direction in order to facilitate fracture of the adhesive bond and release of the bracket from the tooth surface.
