Abstract:

 Background: Dependable bonding between resin cements and high strength ceramics is difficult to attain because of their chemical inertness and lack of silica content that makes etching impractical. Objectives: The aim of this study was to evaluate the effect of different surface conditioning methods on the shear bond strength of zirconia ceramic to resin cement. Methods: Thirty-two zirconia ceramic specimens were constructed from (IPS e.max Zir CAD), and arbitrarily divided into four groups each containing eight specimens for different surface treatment methods. Group 1(NT), No treatment, and served as a control group, group 2 (SC) tribochemical silica coating using 30 μm alumina particles modified by silica and silanization (CoJet Sand system), group 3 (SB) sandblasted with 110 μm aluminum oxide, and group 4 Nd: YAG laser irradiation. A composite resin discs were made-up and bonded to the treated ceramic surfaces using resin luting agent (Panavia F 2.0) and stored for 24 hours in distilled water at 37 OC. Specimens then subjected to thermocycling for 1000 cycles between 5O C and 55O C with a 30 s dwell time. All specimens were subjected to shear bond strength test by a universal testing machine at a crosshead speed of 0.5 mm/minute. The shear bond strength values were recorded. Statistical analysis was done using Statistical Package for Social Sciences (SPSS/version 21) software. ANOVA test was used followed by Post Hoc test to detect the significant between each two groups. The level of significant was 0.05. Results: The mean shear bond strength values for the NT SC, SB, and L groups were 10.37± 0.92, 15.99 ± 2.01, 12.88 ± 0.98, and 18.87 ± 1.17 MPa respectively. Conclusions: It can be concluded that the use of Nd: YAG laser irradiation increases the bond strength of bonding resin cement to zirconia ceramics. Silica coating and salinization is an effective and reliable method to increase bond strength on zirconia ceramics. Sandblasting of zirconia ceramics alone is not effective for achieving good bond strength. [.
