Zirconia,made of Yttria Stabilized Zirconium (YZ) has substantial advantages compared to other dental materials: mechanical resistance, biocompatibility and a fracture toughness two times greater than Alumina.
Strength no longer has to be compromised to achieve extreme aesthetics. The Flexural Strength of Zirconia restorations range from 900 to 1400 MPa. Conventional precious metal ceramics restorations are at 800 MPa or less. Metal ceramics cannot compete with the aesthetics of Zirconia. It is capable of being placed anywhere in the mouth and can accommodate 3-6 unit bridges. |
