Intraoral Characterization Of Monolithic Ceramics: The “Triple R” Protocol, Amr S. EL-Etreby 2020 Association of Arab Universities

Intraoral Characterization Of Monolithic Ceramics: The “Triple R” Protocol, Amr S. El-Etreby

Future Dental Journal of Egypt

A successful life like dental ceramic restoration should be able to blend harmoniously with the adjacent natural teeth. This could be achieved by mimicking and duplicating the natural teeth color, translucency, as well as the surface characterization of natural teeth. Shade matching is an important and a difficult task in mimicking natural teeth that usually leads to unreliable and inconsistent results. Still, a small percent of human teeth shade cannot be matched by available commercial shade guides. The presence of a chair side CAD/CAM system in the dental office eliminates the presence of laboratory steps and hence saving time ...
