ABSTRACT:
An orthodontic arch wire comprises a wire having the same dimensions as previously used orthodontic arch wires. The wire is coated with an opaque coating of a composite material having a thickness of no more than 35 microns, and preferably less than 12 microns. The composite material comprises a resin binder loaded with filler particles for strengthening the coating and making it approximately tooth colored. The composite coating is sufficiently adherent to the arch wire for bending from a straight wire to a curved arch wire installed in a patient's mouth while retaining the aesthetic coating, and to prevent stripping as the arch wire moves through the arch wire slot in an orthodontic bracket.
