Application Of Titanium Alloy in Oral Cavity
Titanium and titanium alloys as medical metal materials can be traced back to the early 1940s, when Bothe et al. first introduced titanium into the medical field; in the early 1950s, the United Kingdom and the United States and other countries first used pure titanium to manufacture bone plates, screws, intramedullary Implant instruments such as nails and hip joints. In 1958, Branemark et al. first introduced titanium alloys to the oral field, pioneered the research on dental titanium implants, and applied them to the clinic in 1965, and proposed the concept of osseointegration; in the 1960s, Buehler The superelasticity and memory effect of titanium-nickel alloys are used to make orthodontic wires; since the 1980s, the United States, Japan, Germany and other countries have begun to use titanium and titanium alloys for the production of dental crowns, bridges, bases, and cards. Rings and crown nails, etc., now titanium has been more and more valued by dentists and patients.
Advantages of oral titanium and titanium alloy materials
①. The amount of melting is small in acidic and alkaline environments, and there is no corrosion and discoloration problems.
②. High safety, no hypersensitivity reactions caused by nickel alloys.
③. Since titanium has no magnetic field interference to magnetic resonance imaging, patients do not need to remove dentures or implants during magnetic resonance imaging examinations.
④. The density of pure titanium is only 4.5g/cm, which is close to the density of natural teeth.
⑤. Pure titanium has low thermal conductivity and no irritation to dental pulp.
⑥. Compared with traditional oral materials, it has the property of not changing the taste of food when chewing. Therefore, titanium and titanium alloys are one of the oral materials with the best clinical application effect so far.
