ABSTRACT:
An orthodontic arch wire and a method of forming the same are disclosed, the method including the steps of coiling a single flexible metallic strand to form a tightly wound helix normally having an array of successively abutting and substantially parallel turns. The helix is made from a material sufficiently flexible to permit bending of the arch wire by selectively and at least partially separating adjacent turns of the helix. According to one presently preferred embodiment, the adjacent turns each lie in a respective plane extending substantially transversely to the longitudinal axis of the helix.
