The purpose of this article is to review the development and applications of titanium and its alloys on dental material, including the elastic modulus, the tensile strength, the yield strength and the extensibility of dental Ti alloys, the effects of halogen ions on the corrosion of dental Ti alloy, the galvanic couple corrosion of Ti alloy combined with others type metal and the microbiological corrosion of dental Ti alloy in oral environment, the surface characteristic and the effect of roughness on the wettability, the recommended alloy elements and using d-electron alloy design theory when designing new dental Ti alloys. The existing problems and the research tendency of dental Ti and Ti alloy were discussed.
