The Advantages of Titanium Dioxide in Dentistry

A versatile material, see how it has made its mark in the dental world.

Titanium dioxide is a widely used and inexpensive material. In bulk, its appearance comes off as a white powder. Commonly used in sun blocks because of its high UV absorption properties and photostability, Titanium Dioxide has a wide variety of uses. When deposited in a thin film through ion beam sputter deposition, its ideal optical coating is perfect for dielectric mirrors.

Titanium dioxide can also be placed directly on a substrate in other ways. One of the simplest methods is to simply oxidize the surface. The titanium dioxide is placed in an open atmosphere where an oxide layer will develop over time. Also, an alternative method may be used to speed up the process. This is done through treatment within an oxygen atmosphere. There have been multiple methods used to oxidize titanium dioxide including physical, chemical, and physiochemical methods.

Being a versatile material, titanium metal and its alloys have played a significant role in dental implant materials because of its good biocompatibility and resistance factors. Although, there have been concern that even though studies suggest that there is a low corrosion rate, it may become enhanced over time and affect the tissues of the human body. Because of this, there have been aggressive studies and enhancements that improve the modification of titanium implants, therefore reducing the risk of corrosion significantly. Research has led to a two-layer corrosion resistant model of the oxide film deposited which has proven to be both efficient and effective.
