초록

The purpose of this study was to compare the tensile bond strength of Comspan and Panavia as a luting materials between electrochemically etched Ni-Cr-Be alloy castings and acid etchea human tooth enamel. Tensile bond strength was evaluated using an Instron testing machine at a crosshead speed of 2mm/min. The following conclusions can be drawn frfm this study ; 1. The tensile bond strength of etched-metal resin-bonded specimen was $179.0{\pm}42.5kg/cm^2$ in case of Comspan and $169.6{\pm}41.4kg/cm^2$ in case of Panavia. 2. The tensile bond strength was not significantly different between Comspan, using with bonding agent, and Panavia, using without bonding agent.
