At present, there is a high demand for full ceramic crowns on fixed partial dentures that are completely metal free. The most commonly used ceramic core material is the yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramic, also known the zirconia crown, due to its optimal mechanical and esthetic properties (1). These crowns are highly resistant to fracture owing to their physical properties (1). We propose that ceramics offer long-term durability, however, saliva commonly causes stress corrosion by reacting with the glass structure, further causing decomposition. Ceramic crowns are also associated with subcritical crack propagation (2,3). By contrast, metal crowns and cores are entirely glass free due to their polycrystalline microstructures, and, therefore offer durability, stability and minimal risk of structural decomposition (3). Few in vitro studies have been conducted on ...
