Abstract:
The shear bond strength of six porcelain repair systems was evaluated in vitro at 48 hours and 3 months. Water storage and thermocycling significantly lowered the mean shear bond strength for all kits tested. However, at the end of 3 months Scotchprime resin had the highest mean bond strength. With current products, porcelain repair remains an interim clinical procedure.
