Aim: In this study we assess the shear bond strength of two resin cements to Grade 5 Titanium (Ti) surface and yttrium-stabilized zirconium oxide ceramic (Zr) surface, with and without surface treatment. Cements tested are RelyX U200 (3M ESPE, Seefeld, Germany) and MultilinkSistem Pack (IvoclarVivadent, Schann, Lichenstein). Materials and methods: We tested eight groups (n = 10): G 1= Zr treated U200; G 2= Zr untreated U200; G 3= Zr treated Multilink; G 4= Zr untreated Multilink; G 5= Ti treated U200; G 6= Ti untreated U200; G 7= Ti treated Multilink; G 8= Ti untreated Multilink. Samples were either untreated or primed with aluminum oxide blasting and cemented. They were subjected to 5000 cycles of thermal cycling and to shear testing. Bond strength values were analyzed with three criteria ANOVA and Tukey's test. Results: Titanium samples with surface treatment showed significantly higher bond strength in comparison with zirconia ceramics, regardless of cement type. Conclusion: Surface treatment with aluminum oxide blasting was efficient to increase cement bond strengthto titanium, and ineffective on zirconia surface.
