چکیده
32 INTERNATIONAL DENTISTRY SA VOL. 8, NO. 4 T here have been significant technological advances in the field of dental ceramics over the last 10 years which have made a corresponding increase in the number of materials available. Improvements in strength, clinical performance, and longevity have made all ceramic restorations more popular and more predictable. Despite improvements these restorations are still time consuming, expensive and technique sensitive when compared to conventional porcelain fused to metal. There are however two principal reasons for allceramic restorations being favoured by the profession.

The main properties (mechanical, thermal and chemical) and clinical application for dental restoration are demonstrated for three types of glass-ceramics and sintered polycrystalline ceramic produced by Ivoclar Vivadent AG. Two types of glass-ceramics are derived from the leucite-type and the lithium disilicate-type. The third type of dental materials represents a ZrO2 ceramic. CAD/CAM technolo...
