ABSTRACT:
A removable orthodontic appliance which has a labial arch wire (20), continuous with a patient's anterior teeth surfaces, that is connected to a pair of clasps (32) seated over several midregion teeth. A pair of structural braces, either molded wings (36) or connecting sections (50), attach the clasps to a lingual arch wire (38) that is made of memory metal to optimize the force of the arch shape on the connected teeth. A bridge, formed by a radial loop (42), is connected between the braces and exerts persistent linear force to the teeth in the opposite direction of deformation. The loop is also preferably made of memory metal and has a constant tendency to return to its original shape, thus controllably effecting the desired tooth relocation. Another embodiment utilizes a number of radial arcs (56) between the molded wings that are placed angularly to not only move the teeth laterally, but retain an angular relationship with the roots of the teeth relative to the patient's basal bone structure. This method non-surgically reshapes the alveolar bone in which the posterior teeth are supported.
