Superelastic and thermally activated TiNi alloys and their applications in dentistry
Superelastic and thermally activated characteristics are two distinct features of TiNi alloys. Besides its good biocompatibility, wear and corrosion resistances, TiNi alloy products played an attractive role in the medical field in the past thirty years. Yet the increasing demand for highly advanced and precise therapy pushed the material scientists to improve their processing technologies from time to time. In this paper, we demonstrated our orthodontics products and endodontic instruments with special treatments, including bending and twisting resistance treatment, surface coated treatment, flawless edges and mirror like finishing. As the resulting products, the dental archwires have outstanding properties of springiness range and also good strength, become more easy to settle in the slots, exhibit remarkable alignment and leveling effect, and make patient comfortable; whereas the root canal files and reamers show high flexibility to adapt the complicated root canal structure, own the sharp edges with high cutting efficiency, and have the long usage life.
