title: Bond strengths of intraoral porcelain repair materials.
abstract: This study investigated the in vitro shear strength of three porcelain repair systems. Glazed and roughened porcelain surfaces were evaluated. The repair systems tested were Fusion, Scotchprime, and Ultra-Bond. Porcelain cylinders were made. Half of the cylinders were wet-sanded to a flat, nonglazed surface and the remaining cylinders retained a smooth, glazed surface. Specimens were subjected to a shear force parallel to the composite/porcelain interface by use of an Instron Testing machine. Statistical analysis (at the 0.05 confidence level) showed significant differences in mean bond strengths related to the porcelain repair systems and the surface texture.
