| Debonding tools and methods especially useful for removing ceramic brackets adhesively bonded to the teeth of a patient. In general, the tool and methods involve applying a tensile force to one side of the bracket while avoiding point loading which may cause the bracket to break. The tensile force may be applied by grasping the bracket with a tool having two jaws and pivoting the tool and the bracket about an axis generally lying in an occlusal-gingival plane of the tooth. At least the portions of the jaws that engage the bracket are formed from a material having a substantially reduced hardness relative to the brittle material of the bracket. Other embodiments of the tool engage a recess, such as one disposed beneath a tie wing, and pry the bracket away from the tooth. | ||||||

| 188 | Orthodontic pliers | US132097 | 1993-10-05 | US5395236A | 1995-03-07 | Suhail A. Khouri |
| The pliers in overall structure resemble conventional orthodontic pliers, but have specialized jaw members adapted to effectuate necessary gingivally directed bends in the distal ends of the arch wire. With reference to an imaginary plane along which the jaw members open and close, a first jaw member projects transversely from this plane and has a free end provided with an angulated, profile facing the longitudinal axis of the pliers. A second jaw member projects transversely to the plane, and has a free end provided with a concave, preferably angulated profile adapted to mate intimately with the convex profile when the jaws are in the closed position. Each of the profiles includes an inner surface closer to the pivot joint of the pliers, oriented perpendicularly to the plane and parallel to the pliers longitudinal axis, and an outer surface farther from the pivot, oriented perpendicularly to the plane and angled obliquely to the longitudinal axis. Preferably, the dimension of the inner surface parallel to the longitudinal axis, is less than the dimension of the outer surface along the oblique angle. Preferably, the outer surface is about 2.5 mm in length, and the inner surface about 0.5 mm in length, defining a ratio of approximately 5 to 1. | ||||||
