不同条件的表面喷砂对牙科氧化锆材料表面丧失的影响

Abstract

Abstract: Objective To evaluate the effect of different sandblasting conditions including sandblasting time, sandblasting pressure and sandblasting alumina powder size on surface loss of dental zirconia. Methods 250 zirconia bars were randomly divided into 25 groups according to different sandblasting pressures (0.1 MPa, 0.2 MPa, 0.4 MPa, 0.6 MPa), sandblasting times (7 s, 14 s and 21 s) and alumina powder sizes (50 μm and 110 μm). The control group did not receive sandblasting. The volume loss, height loss and roughness on zirconia surface after sandblasting were measured and compared for each group. Results The volume loss and height loss were increased with higher sandblasting pressure and longer sandblasting time, but they decreased with larger powder size (all P＜0.05). The surface roughness were increased with higher sandblasting pressure, longer sandblasting time and larger powder size (all P＜0.05). Conclusion Considering the clinical adaptation and surface roughness after sandblasting, sandblasting with alumina particles at 0.2 MPa, 21 s and the powder size of 110 μm is recommended for dental application.
