Abstract:
The bonding ability of Aluminous ceramic, In-Ceram to the enamel and Dentin using different resin cemenst were evaluate in shear bond strength. In this study, the non-precious alloy surface was used as a media to compare the failure interface. Cast metal cylinder (5x10 mm.) were bonded to human enamel dentin and In-Ceram disk (10x4 mm.) the resin cements used were Panavia21, Superbond C&B and Resinomer (with all bond 2) using each manufacturer surface treatment condition. Bonded speciment were stored in 100% humidity at 37 C for 24 hours before randomly tested in shear mode on the Universal testing machine (Autograph, Shimadzu Co., Japan) at crosshead speed of 2 mm/min. The results showed the Panavia 21 exhibited significantly higher shear bond strength between enamel or dentin to In-ceram (at the interface) than Superbond C&B (P<0.05), while Resinomer failed in the analysis since the bond strength to the metal media is not strong enough.
