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.
