ABSTRACT:
An instrument for debonding orthodontic brackets from teeth has a pair of arms with pulling sections adapted to engage the bracket behind occlusal and gingival tie wings. The arms are connected to a lever, and movement of the lever enables the arms to simultaneously exert a pulling force on both of the wings along substantially their entire mesial-distal width in order to lift the bracket from the tooth in straight-line fashion. A pair of reaction supports for engagement with the tooth during the debonding operation extend in an occlusal-gingival direction and have a length less than the occlusal-gingival height of the bracket so that the instrument can be rocked to ensure that the pulling sections are in firm contact with the bracket during the time that the bracket is debonded from the tooth.
