Layered zirconia is more translucent and opalescent, but unlike solid zirconia, it is especially suitable for anterior crowns. Zirconia crowns are comfortable for patients, as they do not transmit hot and cold in the same way as conventional PFMs. 4. High translucent zirconia and layered zirconia can be either screw-retained or cemented. Zirconia crowns may crack or break in the case of excessive or adverse force, however the possibility of breaking or cracking is similar to the possibility of breaking a natural tooth.
