Description

technical field

[0001] The invention relates to a titanium alloy material, in particular to a titanium alloy material suitable for manufacturing dentures. Background technique

[0002] With the aging of the world's population, the demand for denture materials is increasing. Compared with other materials, titanium and titanium alloys have excellent biocompatibility, corrosion resistance, and high specific strength. Since the 1980s, developed countries have begun to study the application of titanium materials in oral restorations, and the research on titanium and titanium alloys has become a hot spot in the study of alloys for dental applications. Commonly used dental titanium alloys are mainly α+β type, such as Ti6Al4VELI, Ti6Al7Nb and Ti5Al2.5Fe, these alloys contain cytotoxic elements and elastic modulus that are not suitable for teeth. Compared with α+β-type titanium alloy, β-type titanium alloy has an elastic modulus closer to that of teeth, which is beneficial to reduc...
