The purpose of this study is to evaluate possibility of using indirect composite resin instead of porcelain through the measurement of shear bond strength between zirconia core and indirect composite resin under treatment of RocatecTM system for improving the adhesion of indirect composite resin. 20 cylindrical zirconia core specimens were divided into 2 groups, according to zirconia surface treatment and attached materials: 1) treated with sandblast and attached with indirect composite resin, 2) treated with sandblast + RocatecTM system and attached with indirect composite resin. The shear bond strength of each experimental group was measured by MTS and the changes of zirconia core surface according to surface treatments were obtained by SEM observation and measurements of surface roughness. The mean shear bond strength values are 0.55+- 0.11MPa (Group SC) and 1.16+- 0.46MPa (Group SRC). The mean Ra values for the surface treatments were follows: 0.39+- 0.13(100ßum sandblast) and 0.50+- 0.03(100ßum sandblast + RocatecTM system). In the analysis of EDS, Si element was detected in the Group SC. The shear bond strength between zirconia core and indirect composite resin was improved significantly by using RocatecTM system.
