The development of composite resin cements that chemically bond to dental alloys has improved the construction of resin-bonded prostheses. Composite resins can be selected for various situations, but specific clinical situations may require different alloys. This study evaluated the ability of a composite resin cement to bond to various dental alloys of different compositions. Ten pairs of disks for each alloy (two NiCr, two NiCrBe, one CuAl, one gold type IV, and one gold for metal ceramic) were bonded to a composite resin cement after air abrasion was performed with aluminum oxide. The disks were then rinsed in tap water and were ultrasonically cleaned in distilled water for 2 minutes. The tensile tests exhibited greater values for alloys ultrasonically cleaned, and the best results were recorded by NiCr and NiCrBe alloys.
与牙科合金发生化学键合的复合树脂水门汀的发展，改进了树脂粘结修复体的构建。复合树脂可针对各种情况进行选择，但特定的临床情况可能需要不同的合金。本研究评估了一种复合树脂水门汀与不同成分的各种牙科合金的粘结能力。在用氧化铝进行空气研磨后，将每种合金的十对圆盘（两对镍铬合金、两对镍铬铍合金、一对铜铝合金、一对IV型金合金和一对用于金属烤瓷的金合金）粘结到一种复合树脂水门汀上。然后将圆盘在自来水中冲洗，并在蒸馏水中超声清洗2分钟。拉伸试验显示，经过超声清洗的合金具有更高的值，镍铬合金和镍铬铍合金的结果最佳。
