cemented because of access problems and lack of proper instruments to perform this task. 8. Classification of dental ceramic restorations. Dental ceramics can be classified in many different ways according to their: : 4. (1) Indication or use. (2) Composition. (3) Processing method. (4) Firing temperature. (5) Microstructure.

Finally, a summary of flexural strength data available for all-ceramic materials is included. Keywords. Ceramics, dental porcelain, crystalline phases. Introduction. Since the first use of porcelain to make a complete denture by Alexis Duchateau in 1774, numerous den- tal porcelain compositions have been developed.

The main objective of this work is to review ceramic dental materials, including their most relevant physical and mechanical properties. A brief historical review, including the evolution of these materials over time, a summary of different dental ceramic classifications, and the composition of dental ceramics will be presented.

so the reader will better understand the ceramics available in dentistry. More importantly, we will give a classifica- tion based on clinical indications for the various materials. Microstructural. Classification. At a microstructural level, we can de- fine ceramics by the nature of their composition of glass-to-crystalline ra- tio. there.
