CAD-CAM and all ceramic restorations, current trends and emerging technologies: A review

Abstract

All-ceramic restorations have revolutionized the concept of esthetics in the practice of dentistry. The increasing use of polycrystalline alumina and zirconia as framework materials and the increasing popularity and variety of CAD-CAM systems seem to be mutually accelerating trends. In fact, CAD-CAM technology opens-up new vistas for increased esthetics. With ever emerging developments, it becomes more versatile and convenient. However, this comes at the expense of making the application more complicated. The present review gives an overview on the different materials available in ceramics used in dental CAD/CAM technology.
