30 Sep CERAMICS, LIKE FUSION-ONE ZIRCONIA, PLAY AN INTEGRAL ROLE IN DENTISTRY
In the last few decades, there have been tremendous advances in the mechanical properties of ceramic materials. While porcelain-based materials are still a major contender in the market, there has been a gradual tendency to replace metal ceramics systems with all ceramic systems. The range and scope for use of ceramics in contemporary restorative dentistry is increased due to advances in bonding techniques. Dental ceramics in restorations are essentially oxide based glass-ceramic systems.
Restorations today are largely required as a result of trauma, decay, gum disease and esthetics. The latter being a more recent area of high demand and one in which ceramic materials play a large role.
Ceramic materials have long been admired for their esthetic qualities. The use of dentally colored glasses can provide replacement structures that can be made to imitate tooth structure in both color, translucency and response to different lighting sources.
Durability is an area that has led to considerable research for ceramic systems that can provide individually constructed restorations, that are small, unique, inexpensive and will be subjected to cyclic loading in wet and sometimes abrasive conditions. Thus ceramics are inorganic, non-metallic materials made by the heating of raw minerals at high temperatures.
The new generations of ceramic materials present interesting options, both in terms of material selection and in terms of fabrication techniques.
