ABSTRACT:
An orthodontic arch wire is arcuately curved in the plane of a patient's mandibular dental arch. Respective end portions of the arch wire are offset inwardly for connection with cuspid surrounding orthodontic bands or bonding pads. The arch wire is provided with one or a plurality of selectively positioned transverse closed loops formed by doubling the wire back upon itself to extend in a lingual direction angled downwardly at an angle of 40.degree. to 60.degree. with respect to a plane normal to the plane of the arch wire permitting the arch wire to be flexed away from the patient's teeth against the torsional resistance normally applied to the teeth by the arch wire. The wire flexing feature permits applying one or more tooth position correcting split sleeves to the arch wire.
