Influence of Surface Treatments on the Shear Bond Strength of Panavia 21 to a Type III Gold Alloy

Abstract

Abstract - Cylinders of Type III gold alloy were sandblasted with either: 50 micron Aluminium Oxide particles (Group 1); CoJetTM Sand (Group 2); the CoJetTM System - CoJetTM Sand followed by application of silane primer (Group 3). Shear testing was undertaken following apposition of Panavia 21 resin. Mean shear bond strengths (+/- standard deviation) were Group 1, 32.9 (+/-18.2) MPa; Group 2, 26.5 (+/-10.8) MPa and Group 3, 45.6 (+/- 25.8) MPa. There was no statistically difference between Group 1 and 2; and between group 1 and 3. However, there was a significant difference between Group 2 and 3 (p< 0.05). While the CoJetTM System achieved the highest mean shear bond strength it conveyed no statistical advantage over the traditional method of sandblasting with aluminium oxide.
