Abstract:
1. A method to permanently apply a desired non-planar shape to an orthodontic archwire, the method comprising the steps of: obtaining a numerical description of a desired non-planar shape of an orthodontic archwire; generating a description of a design of a fixture reflecting said numerical description of an orthodontic archwire; manufacturing a fixture based on the description of the design so that at least a portion of the fixture adapted to receive a wire has a non-planar shape; constraining a wire in the at least a portion of the fixture causing it to adopt a non-planar shape as dictated by the fixture; and exposing the fixture with the wire to conditions to thereby cause the wire to permanently adopt the non-planar shape as dictated by the fixture constrained therein.
