Latest evidence of dental zirconia ceramics from material science

Abstract

Zirconia ceramics are now widely used in dentistry as one of the golden standards of restorative materials. More recently, highly translucent zirconia ceramics and multi-layered zirconia have enabled us to apply monolithic zirconia restorations in both anterior and posterior regions. Several new zirconia materials, as well as different fabrication techniques, have been introduced, which makes difficult to sketch the current status of dental zirconia ceramics. In this paper, we focused on the three aspects of zirconia ceramics: 1) classification of zirconia, 2) sintering of zirconia, 3) additive manufacturing of zirconia, and 4) bonding strategy to zirconia-based restorations. We summarized the novel scientific evidence of dental zirconia ceramics.
