Abstract

The effect of surface treatments and bonding agents on the shear bond strength of composite resin to fractured metal-ceramic restorations is evaluated. Sixty Co-Cr discs were treated with diamond bur, sandblasting, hydrofluoric acid (HF), or their combinations and bonded using Clearfil, Shofu, or All Bond 2. Clearfil showed the highest bond strength, particularly with HF treatment. Shofu performed best with diamond + HF and All Bond 2 with sandblasting + HF. Thus, surface treatment and bonding agent selection significantly impact ceramic repair outcomes.

Keywords
