Abstract
Techniques and methods for utilizing ion implantation to modify dental archwires are provided. An example of a method of ion implanting a wire target includes providing the wire target in an ion implant system, implanting ions into the wire target such that a color of the wire target material after the implanting exhibits a changed appearance from the color of the wire target material before the implanting, and removing the wire target from the ion implant system. An example of a copper-aluminum-nickel (CuAlNi) wire includes an ion implanted atomic species wherein a color of an implanted CuAlNi wire is white, off-white and/or silver and further wherein the implanted CuAlNi wire exhibits mechanical properties of an unimplanted CuAlNi wire.
