Successful adhesive dentistry is reliant on the strength and durability of the resin-bond. This is affected by the alloy and its preparation, the properties of the luting resin, and the condition of the tooth. This in-vitro study investigated three months of preparation of the alloy surfaces and three different types of one resin luting cement. Results demonstrated that alumina-blasted nickel-chromium alloy specimens were significantly more resistant to failure under tensile loading than gold alloy samples however prepared. Alumina-blasted, heat-treated gold alloy specimens showed significantly higher tensile failure loads than those of alumina-blasted gold. The performance of the different resins with the alumina-blasted nickel-chromium or the alumina-blasted, heat-treated gold alloy specimens was similar. However, for the alumina-blasted gold alloy specimens, there was a significant difference when comparing resin types.
成功的粘结牙科依赖于树脂粘结的强度和耐久性。这受到合金及其制备、粘结树脂的性能以及牙齿状况的影响。这项体外研究调查了合金表面三个月的制备情况以及三种不同类型的单一树脂粘结剂。结果表明，经氧化铝喷砂处理的镍铬合金试样在拉伸载荷下比任何制备方式的金合金试样更能抵抗破坏。经氧化铝喷砂处理并热处理的金合金试样的拉伸破坏载荷明显高于经氧化铝喷砂处理的金合金试样。不同树脂与经氧化铝喷砂处理的镍铬合金或经氧化铝喷砂处理并热处理的金合金试样的性能相似。然而，对于经氧化铝喷砂处理的金合金试样，比较树脂类型时存在显著差异。
