Shear bond strength characteristics on surface treatment modalities of CAD-CAM resin polymers.

Statistical analysis revealed that there was a significant difference between the groups. (p<.001) The highest shear bond strengths were achieved for the specimens bonded with Visio. link without physical surface treatments (270.47MPa). The lowest bond strengths were found for specimen surfaces abraded with 110 μm Al2O3 (117.03Mpa) CONCLUSIONS: The results of this laboratory study indicated that the specimens used with Visio.link as provided by the manufacturer had the highest shear bond strengths between the composite resin and high-performance polymer test specimens. Modifications of the high-performance polymer surfaces with carbide burs did not change bonding strengths with the composite materials. This article is protected by copyright. All rights reserved.
