Selection of dental implant materials
The material of dental implant is mainly titanium, and the coating is also based on titanium or titanium alloy. The physical and chemical properties of titanium are famous for its light weight, stainless and high strength processability.
Widely used in medical treatment, such as artificial bones and joints, heart valves, pacemakers, dental implants and so on.
Titanium has good wear resistance and corrosion resistance, mainly due to the formation of oxide film on the surface, which is stable at room temperature and violently oxidized when heated to above 800℃ in air. Semiconductors; Low elastic modulus, close to the bone, can produce * * * vibration; Good biocompatibility, no toxicity, no side effects, no magnetism, no irritation and stability in vivo; Good wettability, not easy to attach organic matter, and good application prospect.
