ABSTRACT: The use of metals and their alloys in restorative and
implant dentistry dates back to centuries. Titanium (Ti) is one of the most
widely used biomaterial for medical implants because of its excellent
mechanical properties and exceptional
biocompatibility. The good biocompatibility of Ti is related to the thin
oxide layer formed on Ti surface. TiO2 is inactive with the surrounding
biological environment and quite compatible with living tissues. However, TiO2 layer can be destroyed during movements between implant and bone tissue under
loading condition. The localized destruction causes corrosion of the implant,
thus, weakening it; and can induce the leak of small metallic particles or
ions into living tissues. This article highlights a review of the various
aspects of corrosion and biocompatibility of dental titanium implants as well
as suprastructures, and the methods to prevent it.
