Biaxial flexural strength of the bilayered disk composed of ceria-stabilized zirconia/alumina nanocomposite (Ce-TZP/A) and veneering porcelain

For dental fixed prostheses, modern patients are prone to select all-ceramic restorations instead of metal-ceramic restorations due to adequate mechanical properties, esthetic and biocompatibility reasons [1]. In particular, zirconia-based all-ceramic restorations have a wide range of applications from single crowns to long-span fixed partial dentures (FPDs) with their high mechanical strengths [2]. In clinical applications, outstanding development and emergence of a variety of dental computer-aided design/computer-aided manufacturing (CAD/CAM) technologies have made it possible to use two main types of zirconia ceramics; yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) and ceria-stabilized zirconia/alumina nanocomposite (Ce-TZP/A) [3].
