Repair strength of heat-pressed ceramics.
The bond strengths of porcelain bonded to porcelain specimens using two different filled resin-based cements were compared by means of notched-disc test specimens. As a control group, unrepaired porcelain test specimens were fractured. Additionally, one group of broken half-repairs was achieved by applying a bonding agent only. The control test specimens had significantly higher fracture strengths (P < 0.05) than the specimens bonded with either bonding agent or resin-based cements. No difference between the resin-based cements was found (P > 0.05).
