Titanium and Titanium Alloy Applications in Dentistry

Titanium and titanium alloy applications in dentistry are as followings:
In 1990s, titanium casting technology was popularized and applied. Because of high dimensional precision, no bubbles and shrinkage cavity characteristics of titanium casting machine, titanium and titanium alloy are used in human hard tissue repair in dentistry.

The thermal conductivity of titanium is the lowest among all dental metallic materials, low thermal conductivity can reduce the thermal stimulation to the dental pulp with a crown, which is very important for dental restoration. Titanium inlay and crown can protect pulp to avoid the hot and cold stimulation.

Titanium material used in dental, originally are most pure titanium. However, pure titanium is lack of strength, poor wear resistance and unstable quality. Titanium alloy has high strength, The most commonly used material in dentistry is Ti-6Al-4V alloy. Afterwards Ti-6Al-7Nb alloy is successfully developed.
