Abstract
An orthodontic arch wire has a generally parabolic shape and includes a curved anterior segment and a pair of posterior segments connected to and extending from respective ends of the curved anterior segment. The curved anterior segment has a circular cross-section and does not have substantially the same flexural rigidity as the pair of posterior segments, at least one of which has a non-circular cross-section. The three pieces are joined together to form the generally parabolic shape.

An orthodontic arch wire having a generally parabolic shape, comprising a curved anterior segment and a pair of posterior segments connected to and extending from respective ends of the curved anterior segment, wherein the curved anterior segment and the pair of posterior segments comprise three discrete pieces, the curved anterior segment having a circular cross-section, at least one of the posterior segments having a non-circular cross-section, the curved anterior segment not having substantially the same flexural rigidity as the pair of posterior segments, and the curved anterior segment and the pair of posterior segments being joined together to form the generally parabolic shape.
