Titanium-based Biomaterials

Compared to cobalt-chromium and stainless steel based alloys, titanium and titanium based alloys have found wide application in biomedicine, and are used as biomedical implants due to their excellent properties, but are yet to be widely used due to the high cost of their production. Their most important properties include: excellent biocompatibility, good mechanical properties, osseointegration, and corrosion resistance. In addition to presenting some commonly used biomedical materials, this article gives an overview of the development of titanium biomaterials and their biomedical applications. Biomaterials are widely used in biomedicine to repair, replace or regenerate body tissue. Given that an increasing number of failed implantations caused by pathogenic bacterial infection are known, among the functions that could be added to biomaterials is antibacterial action, which is of great importance. Recently, antibacterial metal alloys have shown great potential as a new type of biomedical material.
