ABSTRACT:
An orthodontic apparatus for use with a single straight arch wire in both the edgewise and the light-wire techniques to apply a continuous gentle pressure to teeth. One embodiment of the apparatus has a wire retaining bracket made of an elastomeric vinyl polymer which is banded to or molded integral with a band which is affixed to a tooth. The bracket has a pair of parallel upstanding wings which include a horizontal slot and retaining tips for retaining the arch wire. The horizontal slot has a liner formed of a substantially rigid material with the retaining tips formed on the upper and lower walls thereof. The wings have generally triangularly shaped tying tips for use with a ligature wire or elastic connector to apply pressure to a tooth. The tying wing tips also may have horizontal apertures therein for receiving a ligature wire. The bracket also has a vertical tubular aperture extending therethrough for retaining an attachment pin of a "C-clamp" appliance. The wings may also have auxillary springs affixed thereto to generate forces on adjacent teeth. The elastomeric material is easily deflected yet generates a force as it attempts to return to its free shape which aids in straightening the teeth. In another embodiment, the apparatus is a tube made from an elastomeric vinyl polymer which is slipped over the arch wire to apply pressure between two points.
