| Zirconia (ZrO2), known as a kind of bioceramics widely applied in prosthodontics, is considered as a promising alternative to conventional bioceramics owing to its desirable mechanical strength, toughness, wear resistance, corrosion resistance, biocompatibility etc. However, the development of zirconia is hindered due to its instability in long-term clinical observations such as the cracking (chipping) of veneering porcelain and deterioration of mechanical properties of zirconia dental crowns under intraoral condition. The aim of this study is to review the development and actuality of ZrO2 in prosthodontics. In addition, stability problems in commercial zirconia crowns are discussed in detail and the potential solution has been proposed. Furthermore, the authors' ongoing works and perspective has also been put forward. |
