In order to use ZrO2 all-ceramic restorations in the dental field, ZrO2 slurry suitable for SL technology was obtained and ZrO2 bioceramic was prepared by SL. The mechanical properties and biocompatibility were investigated. The transformation from m-ZrO2 to t-ZrO2 or c-ZrO2 in the original ZrO2 powder was completed when sintered at different temperatures. The density of ceramic increases and the number of pores decreases as the sintering temperature increases, and the grain size increases and becomes uneven when the temperature further increases. The Vickers hardness and fracture toughness of ZrO2 bioceramic firstly increase and then decrease when the sintering temperature increases from 1 450℃ to 1 600℃, and they reach their maximum values (i.e., 14.87 GPa and 6.73 MPa·m1/2) at 1 500℃. The linear shrinkage and relative density are 23.42% and 97.32%, respectively. In addition, rat bone marrow mesenchymal stem cells (rBMSCs) were used for in vitro cell experiments, thus proving that ZrO2 bioceramic fabricated by SL technique have a good biocompatibility, which can have some application prospects in dental restoration.
