The adhesion between 4-META resin and two kinds of precious metal alloy (Au-Ag-Pd alloy, Type IV gold alloy) treated by six kinds of surface modification methods, Adlloy, M-primer, V-primer, Silicoater, Type I Tin electroplating, and Type II Tin electroplating, was examined in order to find a way to prevent marginal leakage at the finishing line area of precious metal alloy base denture. The adhesiveness was evaluated by the percolation test and the shear bond strength. Two kinds of finishing line type, the buttjoint type and the slope type, were studied by the percolation test after applying these adhesion systems to removable partial denture with precious metal alloy base.<BR>The results were as follows:<BR>1. Precious metal surface modifications by Adlloy surface modification method and Type II Tin electroplating method improved the adhesiveness.<BR>2. Precious metal surface modifications by Adlloy surface modification method and Type II Tin electroplating method were improved the shear bond strength.<BR>3. By Adlloy surface modification method or Type II Tin electroplating method and the slope type finishing line, marginal leakage was prevented.<BR>From the results, it was suggested that marginal leakage in the finishing line area of precious metal alloy base denture could be prevented by the Adlloy surface modification method or Type II Tin electroplating method and the slope type finishing line.
