Abstract

The purpose of the present study was to reinforce the strength of the bonding between dental precious metal alloys and adhesive heat-curing type resin.<BR>Three kinds of precious metal alloys were treated with three kinds of surface treatment methods, high temperature oxidation with pickling by acid solution and SnO electro-plating method, high temperature oxidation with pickling by acid solution, and only SnO electro-plating method. Adhesive heat-curing type resin containing 4-META was cured on the treated alloy surfaces. The adhesiveness was evaluated by a shear bonding strength test and a pigment percolation test after thermal cycling.<BR>The results were as follows:<BR>1. The porous structure on the alloy surface formed internal oxidation particles after pickling effectively reinforced the mechanical retention between alloys and resin.<BR>2. The SnO electro-plating effectively increased the chemical adhesion between alloys and resin.<BR>3. The method with internal oxidation and subsequent SnO electro-plating superiorly increased the durability and adhesiveness of alloys and resin.
