Effect of slow-cooling protocol on biaxial flexural strengths of bilayered porcelain-ceria-stabilized zirconia/alumina nanocomposite (Ce-TZP/A) disks

All-ceramic dental restorations require good esthetic appearance and sufficient mechanical properties to withstand occlusal or chewing forces because of the inherent brittleness of ceramic systems, which leads to premature failure by repeated contact loading in moist environments [1]. In zirconia-based prosthodontic restorations, ceria-stabilized zirconia/alumina (Ce-TZP/A) nanocomposite ceramic is a promising alternative due to its superior characteristics of high fracture toughness, absence of low-temperature degradation, and reduced framework thickness relative to conventional yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) [2 –6].
