Dental implants consist of an implant and an upper denture, and the implant is made of titanium and titanium alloys. Titanium and titanium alloys have become the most widely used and favored metals due to their good biological properties and ideal mechanical properties.
In terms of chemical properties, it is also an active element. At the moment of exposure to the air, a thin titanium oxide film can be formed on the surface of the material. This titanium oxide film is highly inert and can effectively prevent further Oxidation and corrosion ensure good biocompatibility of titanium.
In terms of mechanical strength, titanium has low density and high mechanical strength. Compared with other medical metals, the elastic modulus is closer to bone tissue, which makes titanium have very ideal biomechanical compatibility and good mechanical processing. The dentures above are mainly all kinds of porcelain crowns. Porcelain crowns are divided into metal porcelain crowns and all-ceramic crowns. There are precious metal porcelain crowns and non-precious metal porcelain crowns.
