Abstract
The application of the Ti-Ni base alloy to dentistry is expected to utilize its shape memory effect and super-elasticity properties. The transformation temperature changes when part of the nickel in a Ti-Ni alloy is replaced with copper. In this study, the super-elastic property of Ti-Ni alloy in which part of the nickel was replaced with 10 mol% of copper was investigated, and the application of this alloy to dental casting was also examined. The results of this study showed that the super-elasticity of dental casted Ti-Ni-Cu alloy with 10 mol% of replacement copper was good and that this maybe a useful method of reducing the quantity of nickel in Ti-Ni based alloy.
