| Abstract | ||
| Objective: The purpose of this study was to evaluate the effect of mechanical and energetic surface treatments of a titanium-abutment (Dentium/ Korea) on the tensile bond strength of a (5) Y Zirconia coping. Methods: forty implant analogs and standard titanium abutments of (5.5mm) in height and (4.5 mm) in diameter were embedded vertically in auto-polymerizing acrylic resin blocks. Zirconia crowns with a special design were fabricated using a CAD/CAM system. Samples were divided according to their surface treatment of titanium abutment into four groups (n 10 for each group); Group (1) acted as control (without any surface treatment for abutment). Group (2) bur surface treatment for an abutment. Group (3) cold atmospheric plasma surface treatment for abutment. Group (4) combine surface treatment with bur and cold atmospheric plasma. Forty crowns of (5)Y Zirconia were fabricated by CAD/CAM system, cemented with treated abutment by Allcem resin cement . After the (5000) cycles of the thermocycling process, crown retention was measured by a universal testing machine. After that each deboned surface was examined stereo-microscopically at a 20x magnification. The experimental results were statistically evaluated with a one-way analysis of variance, Duncan tests the honest significant difference. Results: Significant differences were found between groups based on the type of surface treatment (p>0.01). Conclusion: implant abutment treatment by combining bur and cold atmospheric plasma was the highest group of tensile bond strength followed by bur-only surface treatment. The lowest tensile bond strength was in control group. | ||
