Abstract
Objective: The purpose of this study was to evaluate the effect of MDP containing resin cement and surface treatment of Translucent zirconia and Ultra translucent zirconia on shear bond strength.
Material & Methods: Eighty zirconia discs were constructed . Samples were divided into two groups: Group I: Translucent zirconia samples (n=20) Gro up II: Ultra translucent zirconia samples (n=20) Each group will be subdivided into 2 subgroups according to the surface treatment Subgroup A: Samples will be treated with air abrasion Sub group B: Samples will be left untreated. Each sub group will be further subdivided into 2 subgroups according to bond type: Subgroup 1: samples cemented with MDP containing bond (Universal bond). Subgroup 2: samples cemented with non MDP containing bond (Adper single bon II). All tested samples were subjected to Shear bond strength test.Deboneded samples were examined under the scan electron microscope to determine their mode of failure.Data were statistically analyzed and recorded.
Results: Regarding the effect of ceramic material and resin cement :For MDP containing resin cement, translucent zirconia had a significantly higher value than ultra translucent zirconia. While for Non-MDP containing resin cement there was no significant difference between both materials. Regarding the effect of surface treatment and resin cement for both treated and untreated samples, MDP containing resin cement had a significantly higher value than Non-MDP containing resin cement.
Conclusion: the use of phosphate monomer luting cements on freshly air-abraded zirconia as the simplest and most effective way for zirconia cementation procedure.
