The phase transformation pseudoelasticity of NiTi alloy can reach about 8%. The superelasticity of nitinol varies with the conditions of heat treatment, nickel titanium wire , and begins to decrease when the archwire is heated above 400 oC. When the heat treatment temperature exceeds 600oC, the superelasticity is substantially small. According to this characteristic, the non-orthodontic area of the archwire can be thermally treated to lose its superelasticity in clinic, so as to avoid the influence of the orthodontic process on the teeth in the non-orthodontic area, and the archwire in the orthodontical area still has good elasticity. 3. Sensitivity of temperature change in oral cavity: The orthodattenuation experiment of different archwires, it is found that the vibration amplitude of stainless steel wire is larger than that of superelastic nickel-titanium wire, and the initial vibration amplitude of superelastic nickel-titanium archwire is only half of that of stainless steel wire. The good vibration and shock absorption characteristics of archwires are very important for the health of teeth,ti6al4v eli, while traditional archwires, such as stainless steel wires, tend to aggravate root resorption.
