通常，剪切或拉伸试验用于评估树脂和金属之间的粘结强度。在本研究中，进行了劈裂试验，即双悬臂梁试验，以测量4-Meta树脂和五种合金（钯、钯-银、金、钴-铬和镍-铬合金）之间在空气和水中的粘附能，所述五种合金的表面仅通过喷砂处理或通过两种二氧化硅涂覆方法（Silicoater MD，Rocatec）或通过涂有底漆（V-Primer）来处理。结果表明，在水中储存后，很难将所研究的合金分为牙科基础合金组和贵金属合金组。因此，二氧化硅涂层显著限制了裂缝在水中的传播。除了钯合金必须用Silicoater MD系统处理外，Rocatec系统记录到更高的粘附能值。用V-Primer处理对水解攻击敏感。
Usually, shear or tensile tests are used to assess bond strengths between resin and metal. In this study, a cleavage test, the Double Cantilever Beam test, was performed to measure the adherence energy in air and in water between a 4-META resin, and five alloys (palladium, palladium-silver, gold, cobalt-chromium and nickel-chromium alloys) whose surfaces have been treated by sandblasting only or by two methods of silica coating (Silicoater MD, Rocatec) or by painting with a primer (V-Primer). Results showed that, after storage in water, it is difficult to divide the studied alloys into a dental base alloys group and a noble alloys group. Therefore, the silica coating has significantly limited the propagation of fissures in water. Higher values of adherence energy were recorded with the Rocatec system except with the palladium alloy which must be treated with the Silicoater MD system. The treatment with V-Primer was sensitive to hydrolytic attack.
