초록
This study aimed to illuminate the correlatives between the surface processing of Zirconia core and the shear bond strength. The specimens weremade by precipitating for two minutes in color liquid and drying to produce a colored Zirconia core following the manufacturer’s instructions. Thespecimens were divided into 4 subgroups according to the surface treatment−sandblasted+liner treatment, SLT group; sandblasted treatment,ST group; liner treatment, LT group; non treatment (control), NT group. The specimens were put on the device with regard to ISO/TS 11405, thentested the shear bond strength with 1 mm shearing speed per minute using the Instron multi-purpose tester. The collected data was analysed byone way ANOVA and t-test. After applying the liner and sandblast to the Zirconia core, shear bond strength value were SLT (23.19 MPa), ST (21.17MPa), LT (20.53 MPa) and NT (16.46 MPa) in the order. There was a significant difference in the surface roughness between NT and ST group (p＜0.001), and in the compressive shear bond strength between NT and SLT group (p＜0.05). Therefore, sandblasted plus liner treatment onpre-sintered substructure increased the bond strength of veneering ceramic, compared with other surface treatments.
