ABSTRACT:
Orthodontic archwires and methods of making such archwires. The archwire includes a shape memory alloy having a preset shape for exerting forces on teeth during orthodontic treatment. The alloy, which preferably is comprised of at least three elements (e.g., Ni, Ti and Cu), has a transformation temperature (A.sub.f) greater than about 25.degree. C., whereby the orthodontic archwire produces forces at normal mouth temperature which are greater than the forces produced at normal room temperature. The orthodontic archwire also preferably has a variable modulus of elasticity.
