Quick Reference

A light lustrous metallic element (Ti). Because it is both strong and biocompatible with human tissues, commercially pure titanium or titanium alloy is widely used as an implant material in dentistry and orthopaedic surgery; it has the inherent property of osseointegration. Preparing titanium for implantation involves subjecting it to a high-temperature plasma arc which removes the surface atoms, exposing fresh titanium that is instantly oxidized. The surface of the titanium used for implants may be modified mechanically or chemically by adding or removing material from the metallic surface e.g. by plasma-spraying, grit blasting, acid-etching, oxidation, or coating with hydroxyapatite material.
