测定了三种粘合剂Panavia 21、Superbond、All Bond C&B骨水泥和双固化树脂（Variolink）对Ni-Cr-Be（Rexillium III）、Midigold（III型金）和Amalgam（Sybraloy）的剪切粘合强度。使用800目砂纸制备15个样品，用于Ni-Cr和Midi-Gold，使用100目砂纸制备汞齐。将Ni-Cr-Be和Midi-Gold样品喷砂30 s并蒸汽清洁10 s。使用明胶胶囊将粘合剂粘合到样品上，并在37 ℃的水中熟化24小时。使用Instron以1 mm/min的十字头速度在剪切中使样品脱粘。使用ANOVA和Tukey检验分析数据。Superbond与两种金属合金的结合强度显著高于（P<0.05）任何测试材料，但Panavia 21与金的结合强度除外。All Bond C&B骨水泥分别与Rexillium和Midi-Gold结合时，其结合强度与Panavia 21和Variolink无显著差异。All Bond C&B骨水泥与银汞合金的粘结强度显著高于其他材料（P<0.05）。与Rexillium相比，所有粘合剂对金的剪切粘合强度均较低（P<.001）。两种合金的粘结强度排序如下：Superbond>Panavia 21>All Bond C&B>Variolink。用于粘结的基质的性质和粘结材料本身是铸造金属和用汞合金填充的预备牙齿之间实现粘结的重要因素。Superbond作为粘合剂应能成功地附着所有受试基材，但汞合金可能除外，All Bond C&B骨水泥的效果最好。
The shear bond strength of three adhesives, Panavia 21, Superbond, All Bond C&B Cement, and a dual cure resin (Variolink), to Ni-Cr-Be (Rexillium III), Midigold (Type III gold) and Amalgam (Sybraloy) were determined. Fifteen samples were prepared using 800 grit abrasive papers for Ni-Cr and Midi-Gold, and 100 grit papers for amalgam. Ni-Cr-Be and Midi-Gold samples were sandblasted for 30 s and steam cleaned for 10 s. The adhesives were bonded to the samples using gelatine capsules and were matured for 24 h in water at 37 degrees C. The samples were debonded in shear using an Instron at a cross-head speed of 1 mm/min. The data was analysed using ANOVA and a Tukey test. The bond strength of Superbond to both metal alloys was significantly higher (P<0.05) than any of the materials tested, with the exception Panavia 21 to gold. The bond strength of All Bond C&B cement had shown to be not significant difference from those of Panavia 21 and Variolink, when bonded to Rexillium and Midi-Gold, respectively. The bond strength of All Bond C&B Cement to amalgam was significantly greater (P<0.05) than those of the other materials tested. The shear bond strength to gold showed lower bonding for all adhesives when compared with Rexillium (P<.001). The ranking of bond strength to both alloys was as follows: Superbond>Panavia 21>All Bond C&B>Variolink. The nature of substrate to be used for bonding and the adhesive material itself are important factors in bonding which can be achieved between cast metals and prepared teeth with amalgam filling. Superbond should be successful as an adhesive for the attachment of all substrates tested, with the possible exception of amalgam, for which All Bond C&B Cement gives the best result.
