TI  - Comparison of the Effect of Surface Conditioning Methods on the Bond Strength of Different Zirconia Reinforced Lithium Silicate and Hybrid Ceramics to Resin Cement
AB  - Objective: The objective of this study is to investigate the effect of surface treatment techniques on the shear bond strength (SBS) of resin cement bonded to CAD / CAM materials. Methods: The zirconia-reinforced lithium silicate, Vita Suprinity (VS) and Celtra Duo (CD), and hybrid ceramics, Vita Enamic (VE) and Nacera Hybrid (NH), were used. Eighty specimens from each material were fabricated following the manufacturer’s instructions and separated into 8 groups according to surface treatments. These were; K (control, no treatments), H (hydrofluoric acid), HS (H+ Silane S), A (abraded with 50-micron alumina particles A), AS (A+ S), C (abraded with 30-micron Cojet sand C), CS (C+S), S. The mean surface roughness (SR) of the specimens was evaluated. Surface treated specimens were cemented to the resin cement (Panavia F 2.0) for testing the adhesion using the shear bond strength (SBS) test. Mean SR and SBS were evaluated by 2-way ANOVA with the material type and surface treatments techniques as the independent factors. Results: A and AS groups were observed to have the highest SR values. Both hybrid ceramics VE and NH showed the highest SR values among surface treatments. The highest SBS values were found usually on the H and HS treated surfaces. The highest values were observed on the CD material in the HS group (18.01MPa) and followed by the VE material (16.25 MPa) in the CS group. For CD and VS materials, adhesive and cohesive failures were found; and for VE and NH materials, adhesive and mixed cohesive failures were observed. Conclusion: The surface treatment showed a significant effect on SR and SBS values. Although the SR values of the materials are high in the A and AS group, the highest SBS values were observed on H and HS treated surfaces.
