Abstract

A superelastic orthodontic archwire made of an alloy of Nickel Titanium Iron combines substantially low and constant forces with bendability characteristics. This allows the same archwire to be used for all stages of orthodontic treatment. Also disclosed is a method of producing the archwire by winding a suitably shaped mandrel with Nickel Titanium Iron alloy wire and restraining the wire to secure its shape. The mandrel is provided with a plurality of apertures adapted to receive independent heat elements. Heat elements are inserted into the mandrel, and energized. A thermocouple is carried by the mandrel to detect a target temperature, whereupon a controller unit shuts off the heating elements. The heating elements are removed, and the mandrel with attached wires cooled at a suitable rate to maximize the desired characteristics entrained into the wire.
