Medical titanium material As a new type of alloy and a carrier material, it is widely used in limb implantation, alternative functional materials, dentistry, medical devices and other related fields. Titanium and titanium alloys are characterized by good corrosion resistance, high specific strength, low elastic modulus, fatigue resistance and good biocompatibility. Among them, the good biocompatibility makes it have unique advantages compared with other metals, so it is widely favored in the medical field. However, due to its low wear resistance and process performance, efforts are also being made to further improve it.

With the rapid development of the national economy, the demand for medical titanium materials in the medical field is increasing with its excellent performance. As metal materials with excellent biological properties, titanium and its alloys have a good application prospect in the medical field. However, compared with developed countries, there is still a certain gap in the research, development and application of titanium alloys in China. For example, titanium alloys have high elastic modulus, poor surface activity, poor wear resistance and corrosion resistance, which will directly affect the biocompatibility of materials. Therefore, in order to develop new titanium alloys with better comprehensive performance, China should strengthen the research and development of materials, pay attention to innovation, and develop biomedical titanium materials with low elastic modulus, high wear resistance, corrosion resistance and excellent biocompatibility.

Titanium has good affinity with human connective tissue and bone epithelial tissue, and its excellent mechanical properties also reflect its advantages in medical alloys. Because of its small density, light weight, good corrosion resistance and comfortable wearing, titanium is widely favored as a denture (implant tooth). In addition, after surface treatment, the aesthetic properties of titanium dentures increase, which can meet the public's demand for beauty and give people visual enjoyment.
