Yttria-stabilized zirconia(YSZ) has been widely used as a dental restorative material due to its excellent mechanical properties. However, YSZ, which is mainly used as a dental material, is optically opaque and has low temperature degradation(LTD). Recently, as interest in aesthetics increases, translucency similar to real teeth is being emphasized. As a result, there is an increasing demand for full-contour zirconia which improves translucency by introducing a higher content of cubic phase despite the deterioration of mechanical properties. Therefore, the goal is to improve the mechanical properties of zirconia with high cubic phase content. For this study, two-step sintering and doping processes were implemented to YSZ with high cubic content to reduce the grain size and to enhance the mechanical properties. |
