Abstract
Predictable cementation is one of the most important factors for achieving clinical success with any restorative material, including Y-TZP. However, the cementation method using mechanical and chemical adhesion remains controversial for Y-TZP, unlike for glass or alumina-based ceramics. Conventional adhesive procedures, including acid etching and silanization, are not effective in achieving strong bonds between zirconia ceramics and resin cements because zirconia has a silica- and glass-free structure.
Thirty-six zirconia discs received one of the following treatments: airborne particle abrasion with 50-μm aluminum oxide particles, fusion sputtering, while as-sintered specimens served as a control. Four-treated surface of zirconia samples was examined using 3D laser scanning microscope to assess the surface roughness and scanning electron microscope to study the surface structure of each group. Half of the specimens of each group were bonded using (Z-PRIME Plus) and MDP-containing self-adhesive resin cement (Panavia SA cement plus) while the other bonded directly using only the same resin cement (Panavia SA cement plus). The specimens were thermo cycled in water for 5000 cycles between 5 and 55◦C. Micro-shear bond strength test was performed using universal testing machine until bonding failure. Failure modes and fracture surface topography will be evaluated with scanning electron microscope.
The fusion sputtering surface treatment and primer (Z-PRIME) application significantly influenced zirconia-resin bond strength (p<0.001). The lowest value was observed in-group C2 as-sintered without Z-PRIME application (4.053±3.72).

Conclusion: fusion sputtering surface treatment enhanced the micro-shear bond strength of zirconia and resin cement. Z-PRIME application influenced the bond strength of zirconia and self-adhesive resin cement.
