    摘要： An orthodontic appliance includes a portion made of a shape memory alloy having a base alloy composition of at least two different metallic elements and a treated region having an alloy composition that is depleted in at least one of the metallic elements. The base alloy may include a nickel titanium alloy (NiTi), a copper chromium nickel titanium alloy (CuCrNiTi), or a copper aluminum nickel (CuAlNi) alloy. The treated region may be depleted in at least one of copper, aluminum, nickel, and titanium relative to the base alloy composition by exposing the base alloy to a source of energy. The base alloy composition has a first austenitic finish temperature and the treated region has an austenitic finish temperature that may be different than the first austenitic finish temperature. The treated region may form a part of an archwire, a stop, a hook, a crown, a band, or an orthodontic bracket.

    摘要： A method for altering an orthodontic archwire of a unitary piece of shape memory alloy having a composition and generally uniformly formed properties along its length to different stiffness profiles along the length of the archwire. In one embodiment, the method includes determining a stress profile for teeth at a location. The method may include calculating a force the archwire is to produce on the teeth to satisfy the determined stress profile and determining an altered stiffness of a section of the archwire based on the calculated force. The method may include changing the composition of the section based on the determined altered stiffness. The method may include determining a load for teeth and calculating a force the archwire is to produce on the teeth to satisfy the determined load.
