- Purpose: The purpose of this study was to investigate the effects of etching by monitoring the etched surfaces and the shear bonding strength of resin and porcelain with etched zirconia. Methods: The CAD/CAM was used to produce 24 zirconia blocks in groups of six. The zirconia specimen surfaces were sandblasted, and they were then divided into 12 specimens with surface etching and 12 specimens without etching for the control group. 12 specimens of composite resin were bonded using a curing light, and 12 specimens of porcelain underwent vita porcelain build-up sintering and the shear bonding strength was measured using a universal testing system. The SEM photographs were taken in order to observe any differences in the surfaces before and after etching, and they were magnified by a factor of 8 in order to observe fractured surface types. Results: The results of the shear bonding strength measurements are as follows: For the composite resin tests, between zirconia and resin, the shear bonding strength of the control group (NZR) without surface etching was 4.68 Mpa and the experimental group (EZC) with surface etching was 9.65 Mpa, which is significantly higher. The crystal structure of the zirconia was confirmed to be different in observations of the surfaces before and after etching. Conclusion : In comparing the shear bonding strength of zirconia and composite resin, the effects of etching were found to be significant. The effects of surface etching were also observed in fractured surfaces between zirconia and porcelain. This is expected to be applicable to various prosthetics as surface etching on zirconia is used in clinics.
