Bond strengths of porcelain repair adhesive systems.

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