ABSTRACT:
An orthodontic arch wire adapted to be received within the channel of an orthodontic bracket includes a plurality of flexible metallic strands wound into a tightly wound elongated coil normally having an array of successively abutting and generally parallel turns. The coiled wire is made from a material sufficiently flexible to permit bending of the arch wire by selectively and at least partially separating adjacent turns thereof. According to a preferred embodiment, the wires are wound interleaved with one another so that adjacent turns are formed by different strands. A plurality of wires may be associated together to form a composite strand, and this composite strand may be used to form the elongated coil.
