Abstract: A retention wire for a tooth which has two ends, one end being adapted to lie against the outside surface of a tooth in front of the back tooth in a plurality of teeth, the other end passing backwardly around the back tooth, then forwardly to the front of the front tooth in said plurality and around it where the second end terminates. The retention wire may include a retention wedge mounted on it comprising a planar sheet of high strength material such as stainless steel, plastic and the like adapted to be placed against the surface of a tooth. The surface which engages the tooth is covered by adhesive material to bond it to a tooth. This adhesive material preferably is in the form of a sheet which is able to bond it both to the wedge and a tooth. The retention wire extends beyond the wedge at both sides thereof. One end is adapted to go around the tooth and engage the inner surface thereof. The other end also extends beyond the side of the wedge where it terminates in a loop which may rest against the gum.
