This in vitro study was conducted to evaluate effect of surface treatment and two resin cements on marginal integrity of zirconia crowns.

Materials and Methods: Forty zirconia crowns (Amann Girrbach AG,Austri) were fabricated and divided into2 groups according to type of resin cement, group 1 Rely x ultimate clicker (3M Deutschland ,Germany ) and group 2 Rely x unicem (3M ESPE,USA) , each group was then subdivided into 4 groups according to type of surface treatment , no surface treatment, sandblasting, sandblasting with silane, sand blasting with MDP . After cementation each specimen was photographed using USB Digital microscope with a built-in camera (Scope Capture Digital Microscope, Guangdong, and China) for measuring and evaluation of gap width.

Results: group 2 showed higher significant mean of marginal gap than group 2.

Conclusion: group 1 Rely x ultimate clicker resin cement showed less marginal gap than group 2 Rely x unicem resin cement.

Keywords: Surface treatment; resin cement; zirconia
