Wear of Different CAD/CAM Ceramic Materials with Various Surface Finishing Protocols

Abstract

Enormous development in the dental field, and the continuous research in the scope of dental materials yielded the production of new dental ceramics. The new materials produced always look up to match ideal properties of natural teeth . So , they should be both mechanically sufficient and esthetically pleasing and in harmony with the human dentition. A ceramic with these two essential qualities serves properly in the oral environment . However, No sufficient data is available on how long these materials will attain their smooth surface and how rough they can be after long time under function, which might jeopardize the success of the restoration, and in addition, damage the opposing dentition.
