Because of the potential usefulness of titanium-nickel (Ti-Ni) alloys in a wide variety of applications, the properties and characteristics of these materials are currently being intensively investigated. Of particular interest are their super-elasticity, shape memory, and ability to damp vibrations. We measured the damping capacity of super-elastic Ti-Ni alloy orthodontic wires and traditional stainless steel orthodontic wires with a laser displacement apparatus. The damping curve of super-elastic Ti-Ni alloys as a function of load decreased abruptly, while that of stainless steel wires decreased gradually as a function of load. We measured specific damping capacities (SDC) of both types of wire, and we found that the damping capacity of super-elastic Ti-Ni alloy wire is higher than that of stainless steel wire. We tested two types of super-elastic Ti-Ni alloy wires, and we found that improved super-elastic Ti-Ni alloy wire had a higher SDC than did the conventional super-elastic Ti-Ni wire.
