Abstract :

Titanium (Ti) and some of its alloy have been the alternative metal for removable denture
framework due to their high strength, light weight, low modulus, excellent corrosion resistance
and excellent biocompatibility. However, several practical problems including casting difficulty,
permanent deformation of Ti clasps, debonding of the denture base resin from the Ti framework,
discoloration of Ti surface and poor wear resistance have limited their popularity. This article describes
the development and properties of titanium and reviews the differences between titanium and its alloys
comparing to cobalt-chromium alloy. The recent improvements and limitations of the usage have also
been listed as the guideline for metal selection in removable denture framework construction.
