Bond strengths of porcelain repair adhesive systems.
This study compared the shear bond strength of resin composite bonded to porcelain with six commercial porcelain repair adhesive systems. The porcelain repair systems tested were: All-Bond 2, Clearfil Porcelain Bond, Ceram-Etch, C&B Metabond with Etch-Free Primer, Scotchprime, and Ultradent Porcelain Etch. Resin composite cylinders were bonded to primed porcelain surfaces and the specimens were thermocycled and stored in distilled water at 37 degrees C for 36 days. After storage, a testing machine was used to deliver a shear force parallel to the porcelain/composite interface. Mean load to failure was calculated for each group and the fracture location was noted. Results demonstrated cohesive porcelain failures and high bond strengths for All-Bond 2, Clearfil, Metabond, Scotchprime, and Ultradent. Statistical analysis revealed significantly lower bond strengths for the group that failed at the porcelain/composite interface.
