Purpose: The aim of this research was to investigate difference in shear bond strengths of full-contour zirconia layered with porcelain. Methods: Disk-shaped (diameter: 12.0mm; height:3.0mm) zirconia were randomly divided into six groups according to the surface conditioning method to be applied (N=90, n=15 per group): group 1-contol group(ZC); group 2- airborne particle abrasion with 50-um Al2O3(5A); group 3-50-um Al2O3 + liner(5AL), group 4-110-um Al2O3(1A); group 5-110-um Al2O3 + liner(1AL); group 6-liner(LC). On each block, zirconia porcelain was build up according to manufacturer’s instructions. All samples were fixed with measuring jigs and shear bond strength were measured with Universal testing machine. Collected data were analyzed using SPSS(Statistical Package for Social Sciences) Win 12.0 statistics program. Results: LC showed the highest value(29.92±2.55 MPa) and ZC showed the lowest value(13.22±1.37 MPa). Zirconia liner and Alumina oxide groups was significantly higher shear bond strength than control(p<0.05). 5A (without liner 22.18±2.37, with liner 22.84±1.74 MPa) was higher shear bond strength than 110 (without liner 20.18±2.38, with 20.71±2.67). Conclusion: Surface treatments may have advantage in bond strength improvement for full-contour zirconia layered with porcelain.
