Metal ceramic restorations were considered the gold standard as reliable materials. Increasing demand for esthetics
supported the commercialization of new metal free restorations. A growing demand is rising for zirconia prostheses.
Peer-reviewed articles published till July 2013 were identified through a Medline (Pubmed and Elsevier). Emphasizing
was made on zirconia properties and applications. Zirconia materials are able to withstand posterior physiologic loads.
Although zirconia cores are considered as reliable materials, these restorations are not problem free.
