Abstract:

An orthodontic archwire includes an anterior region, bicuspids regions and posterior regions. The archwire exhibits substantially constant unloading force in at least one of the anterior region, bicuspids regions and posterior regions, having a variation of unloading force of less than 15 gf during unloading from about 2 mm to about 0.6 mm deflection. A set of orthodontic archwires can have the property that the anterior region of a first archwire has substantially the same clinical working force as the anterior region of a second archwire, the bicuspids regions of the first archwire has substantially the same clinical working force as the bicuspids regions of the second archwire, and the posterior regions of the first archwire has substantially the same clinical working force as the posterior regions of the second archwire.
