Abstract: The large choice of ceramic materials for an indirect restoration has given clinicians a dilemma when choosing a suitable ceramic for restorations in anterior or posterior teeth. Focusing principally on the most commonly used materials, lithium disilicate and zirconia, the aim of Part 1 of this article is to compare the mechanical properties and aesthetics of these two materials. For strength, zirconia possesses superior physical properties when compared with lithium disilicate. However, in terms of aesthetics, lithium disilicate holds advantages. With both materials having different microstructures, the same cementation protocols cannot be used. Other contemporary ceramic materials are briefly reviewed. Part 2 reviews the latest clinical research on their clinical performance.

Clinical relevance: Awareness of which ceramic material performs optimally on anterior and posterior teeth is clinically important.
