ABSTRACT:
A method and apparatus for creating an orthodontic archform and forming an archwire. The method includes setting up separated model teeth in a setup fixture to mutually locate the brackets relative to the model teeth, with the teeth supported on a setup plate structure. The model teeth are transferred on the setup plate structures to an alignment fixture and positioned in a curved archform. An archwire forming fixture is substituted for the teeth on the alignment fixture, an archwire is clamped in an archwire slot in this assembly, and then heat treated. Insulative shaping pins are positioned along the archwire to add compound curves or loops.
