Theadhesionbctween4-METAheat curing resin and two kinds of preciousmetal alloy (Au-Ag-Pd alloy and Type IV gold alloy) treated by six kinds of surface modification methods, Adiloy, M-primer, V-primer, Silicoater, Type I Tin electroplating (Kura, MODEL 100), and Type IL Tin electroplating (Kuraace Mini), were 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. The results showed that precious metal surface modifications by Adiloy surface modification method and Type II Tin electroplating method improved the adhesiveness and the shear bond strength.The durability of adhesion was evaluated by the shear bond strength after the thermal cycle test. The results showed that precious metal surface modification by Type II Tin electroplating method improved the shear bond strength.As to the shape of finishing line, twokindof finishing line type, the conventional bud-joint type and the transition type with slow inclined plane were examined by the percolation test. The later indicated better adhesiveness.From these results, it was suggested that the marginal leakage in the finishing line area of precious metal alloy base denture using 4-META heat curing resin could be prevented by the Type II Tin electroplating method and the transition type finishing line.

4-META热固化树脂与两种贵金属合金的粘接（Au-Ag-Pd合金和IV型金合金）通过六种表面改性方法处理，Adiloy，M-底漆，V-底漆，硅涂层，I型镀锡（Kura，MODEL 100）和IL型锡电镀（Kuraace Mini），为探讨防止贵金属基托义齿边缘渗漏的方法，采用渗透试验对边缘渗漏进行评价和剪切粘结强度。结果表明，采用Adiloy表面改性法和II型电镀锡法对贵金属进行表面改性，提高了镀层的附着力和剪切结合强度，通过热循环试验后的剪切结合强度评价了镀层的附着耐久性。结果表明，采用Ⅱ型镀锡方法对贵金属表面进行改性，提高了镀层的剪切结合强度;对于镀层的精整线形状，采用渗流试验对常规的芽接型和缓斜面过渡型两种精整线进行了考察。结果表明，采用Ⅱ型电镀锡方法和过渡型精整线可以有效地防止4-Meta热固化树脂基托义齿精整线区域的边缘渗漏。
