Abstract:
1. A pair of orthodontic pliers for bending orthodontic arch wires, comprising: first and second elongated actuating members, each actuating member including a handle portion for grasping in the hand, and a head portion comprising a body portion extending from the handle, the actuating members being pivotally joined at their respective body portions so that the head portions can be moved toward and away from each other into respective closed and open positions; a first, upper occlusal jaw and a second, lower occlusal jaw formed at respective tips of the head portions of the actuating members where the first and second occlusal jaws project at an obtuse angle from the body portion, and have an internally angled V-shaped channel extending longitudinally along each occlusal jaw in a direction transverse to the body portion, where each of the V-shaped channels defines an angle of about 80 degrees and the channels are arranged to face one another; a central support arm pivotally coupled to both body portions and positioned between the head portions such that the central support arm lies parallel to and in the same operating plane of the handle portions; a gingival jaw member of rhomboidal shape projecting from an upper surface of the central support arm at the same obtuse angle as the occlusal jaws, the gingival jaw member having upper and lower externally angled corners forming angles of about 80 degrees, where the corners are adapted to mate with the internally angled V-shaped channels of the upper and lower occlusal jaws, respectively, when the head portions are in the closed position, where the central arm and the gingival jaw member pivot freely toward and away from the occlusal laws to accommodate an orthodontic arch wire therebetween for bending; wherein the pliers are capable of intraorally bending arch wires in all quadrants of the mouth due to the complementary configurations of the gingival law and occlusal jaws.
