The introduction of a promising new ceramic material called zirconia aims to solve the issue of mechanical failure while also providing aesthetic advantages. In these types of restorations, ceramic layer chipping is the most frequent issue. Monolithic zirconia with CAD/CAM processing has been introduced, which offers a number of benefits, to address these shortcomings. The use of lithium di silicate has grown in popularity for anterior restorations because of its great aesthetics and suitable mechanical characteristics. This clinical evaluation compares the benefits and drawbacks of monolithic lithium di silicate vs. monolithic zirconia in FPD.
