We have chosen five commercially available adhesive resins, Super-Bond C&B (SB), SB for opaque resin (SBO), Panavia 21 (PV), Bistite II (BR) and Imperva Dual (ID), and investigated on their tensile adhesive strength (σt) and fracture toughness (GIC), and δt and GIC after 4/60°C themal-cycling for evaluating a durability, comparatively. The adherend used was a non-precious metal. The major findings were as follows. No great difference in σt of SB, SBO, PV, BR and ID was recognized. But, in GIC, the value (GIC= 592J/m2) of SB without filler was 9 to 14 times as many as that of PV, BR and ID with filler. In all adhesive resins, by thermal-cycling test, their adhesive strengthes were not affected very much. And their fracture modes were observed as cohesive fracture. Next, in fracture toughness after thermal-cycling, the values of PV, BR and ID showed 4 to 31 percent decrease in order of the symbolized adhesives, and the value of SB notably lowered and showed 86 percent decrease. And the fracture mode of SB changed to interfacial fracture. These results revealed that a mechanical property after thermal-cycling was affected considerably by a size of test specimen, therefore, there is the possibility that we evaluate the durability of adhesive resin by mistake.
