Abstract

The effects of surface conditioning methods on the microtensile bond strength of Y-TZP ceramic were studied based on airborne particle abrasion and resin cements. Eight square-shaped (12 mm×5 mm high) Y-TZP ceramic were studied blocks (LAVA™, 3M ESPE, USA) and flat occlusal dentin blocks were fabricated, pre-treated(airborne abrasion with 125μm Al2O 3 particles, tribochemical silica coating with 110 μm Al 2O3 particles modified by silica oxide), and bonded to each other using resin cements(Panavia F 2.0, RelyX Unicem). Thereafter the trilayer specimens were cut into microbar specimens with a bonding area of approximately 1.0±0.1 mm2 and then microtensile bond strength tests were performed. The Y-TZP ceramic following airborne particle abrasion with 125μm Al2O3 and silicoating, the surface roughness of Y-TZP and its surface silica content were confirmed to increase. Overall, the Y-TZP ceramic surface treatment with a tribochemical silica coating showed the highest microtensile bond strength of the phosphate monomerbased resin cement to Y-TZP ceramic(mean MPa= 18.11±0.27(Panavia F 2.0), 17.45±0.39(RelyX Unicem). In cases in which a silica coating was applied, there was no significant difference in the bonding strength depending on resin cements (P>0.05).
