Abstract
The effect of five different surface treatments on the shear bond strength of the resin bond to Type IV Gold alloy was studied by bonding resin to metal. The metal surface was subjected to one of the following treatments and bonded ; (1) air abraded with 50㎛ alumina particles, (2) beads (3) beads and tin-plated at current density of 300mA/㎠, (4) tin-plated at current density of 300mA/㎠, (5)silicacoating with Sililink, and bonded with an MDP Opaque primer, CESEAD resin system, The bonded specimens were immersed in water for 23 hours after 1 hour resin curing and shear bond strength were recorded. @ES On the basis of this study, the following conclusions can be drawn; @EN 1. Difference were found in the shear bond strength among all experimental groups, and bead group exihibited the highest shear bond strength and sand blasting group exhibited the lowest shear bond strength on five groups. 2. Bead group, mechanical bonding was significantly higher than that obtained with the samples, tinplating, silicacoating, and chemical bonding. 3. No statistically significant difference was found between the shear bond strengths obtained with bead and bead-tinplating, and between tinplating and silicacoating.
