There is a scarcity of evidence-based research supporting the use of contemporary ceramics in dental practices today. Poor clinical trials eventually lead to poor systematic reviews, and load to failure laboratory tests have little clinical relevance. This leaves clinicians in doubt about which ceramic restorative material is best for their patients. The presentation will focus on lithium disilicate and monolithic zirconia, including the various generations. This will include a discussion of mechanical and optical properties, wear of natural antagonists, as well as ceramic adjustment, finishing, and polishing.  A series of new retrospective studies will also be introduced to evaluate the survival of these ceramics.

Objectives:

1. Understand the mechanical (including wear characteristics) and optical properties of lithium disilicate and zirconia materials, as well as their implications for clinical practice

2. Determine the best preparation design and cementation procedure for each ceramic material.

3. Evaluate the projected clinical success of these two materials, based on the most current research.
