Flexural Strength and Morphological Study of Different Multilayer Zirconia Dental Materials.

Nowadays, yttria (Y)-stabilized ZrO (Y-TZP) is the most commonly used material in dental prosthetics. Y-TZP dental ceramics are mainly stabilized via the addition of 3 mol% yttrium oxide (YO). These ceramics exhibit excellent mechanical properties, including high flexural strength, fracture toughness, elastic modulus, etc.
