Effects of Different Porcelains and Shades on Light Transmission and Resin Polymerization

The aim of this manuscript is to describe 2-year follow-up of a clinical experience with a zirconia-reinforced lithium silicate ceramic for an anterior rehabilitation with single metal-free crowns. The maxillary-central incisor teeth crowns were made by zirconiumreinforced lithium silicate and covered with porcelain were obtained with a digital impression with the intra-oral scanner of the CEREC system as a basis for virtual design, as well as a laminate for the left lateral maxillary incisor, based on a “double scanning” technique. Lithium silicate material seems to be a safe and satisfactory alternative for anterior crowns’ rehabilitation.
