Mechanical Characteristics for Orthodontic NiTi Wires

摘要

The materials such as the shape memory alloys in the medical field ensures the possibility of designing and practical achievement of certain cosmetic dentistry works with special advantages regarding the enhanced biocompatibility, superelasticity. The Ni-Ti alloys, have the characteristic of superelasticity which is around 20 times higher than that of stainless steel.The experimental program included the mechanical caracyeristics four NiTi orthodontic wires: traction test, determining the elasticity, alternating bending test, determining the hardness.
