Low Temperature Degradation of Y-TZP Ceramic for Dental Applications

摘要：

　　Yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramic has been recently introduced into prosthetic dentistry for the fabrication of crowns and fixed partial dentures (FPDs).The mechanical properties of Y-TZP are the highest ever reported for the all-ceramic materials.This is favorable for the fabrication of multi-unit posterior bridges and the substantial reduction in core thickness.However, Y-TZP ceramic is susceptible to low temperature degradation (LTD), which is detrimental to the long-time survival and aesthetics of zirconia restorations in vivo.This review summarizes the characterization, mechanisms, and influencing factors of the LTD in dental Y-TZP ceramic.In addition, the recent trend of exploring high aging resistant zireonia-based dental ceramics is discussed.
