Abstract

Comparisons of simple surface preparation of the dental Au-Ag-Pd alloy for improving the adhesion to 4-META/MMA-TBB resin cement were carried out by bonding metal to metal and metal to the etched enamel.<br>The anodized surface with phosphoric acid after sandblasting kept sufficient bond strengths during immersion in water at 37°C for three months, whereas that after cleansing showed a marked decrease in bond strengths during immersing times from one up to three months. Bond strengths of the surface only sandblasted were low in the early stage of water immersion but increased during immersing times from one up to three months.<br>It appeared that 4-META/MMA-TBB resin cement continuously formed new adhesion even during immersion in water.
