Abstract:

Purpose: To compare on effects of different surface treatments, such as acid etched and Laser treatments of titanium surfaces especially new alternatives on the adhesive strength between resin and titanium surfaces. Methods: Sixty titanium grooved disks (makro etched) were prepared and they were seperated into five groups as follows: 1) No treatment-control group; 2) Sandblasted group with aluminium oxide; 3) Tribochemical procedure group in the laboratory; 4) Tribochemical procedure group in the clinically; 5) Nd:YAG Laser-irradiated group. The topographic patterns were observed by scanning electron microscopy. After these tests, resin cement was applied to the titanium surfaces. Shear bond test was performed via a universal testing machine at a crosshead speed of 0.5 mm/minute. In addition, the correlation between the surface roughness and bond strength was checked using Spearman correlation test (The mean difference is significant at the 0.05 level). Results: The highest mean shear bond strength was recorded with Tribochemical procedure group in the laboratory (rocatec plussilan) 15.701±2.62) and the lowest with the control group (5.23±2.49 MPa). Conclusion: All of the surface treatment methods that were used in present study increased the bond strength between resin and titanium surface.
