This study compared the durability and shear bond strengths of combinations of three adhesive primers and three resin cements bonded to silver-palladium-copper-gold (Ag-Pd-Cu-Au) and cobalt-chromium (Co-Cr) alloys. The adhesive luting cements Imperva Dual, Panavia 21, and Super-Bond C&B and the adhesive primers Metal Primer material, V-Primer material, and Cesead Opaque Primer material were used. The application of Metal Primer material was effective in improving the shear bond strengths between each of the three resin cements and Ag-Pd-Cu-Au alloy compared with nonprimed specimens. Co-Cr alloy primed with Cesead Opaque Primer, followed by cementation with Imperva Dual or Super-Bond C&B luting cements yielded the strongest shear bond strengths after 50,000 thermocycles, and Panavia 21 cement did not reveal any significant differences in bond strengths between nonprimed specimens and those primed with Cesead Opaque Primer at all thermocycles.
本研究比较了三种粘结剂底涂剂与三种树脂水门汀组合粘结到银钯铜金（Ag-Pd-Cu-Au）合金和钴铬（Co-Cr）合金上的耐久性和剪切粘结强度。使用了粘结性粘结水门汀Imperva Dual、Panavia 21和Super-Bond C&B，以及粘结剂底涂剂金属底涂剂材料、V-底涂剂材料和Cesead不透明底涂剂材料。与未使用底涂剂的试件相比，使用金属底涂剂材料能有效提高三种树脂水门汀与Ag-Pd-Cu-Au合金之间的剪切粘结强度。用Cesead不透明底涂剂处理Co-Cr合金，然后用Imperva Dual或Super-Bond C&B粘结水门汀粘结，在50000次热循环后产生最强的剪切粘结强度，并且在所有热循环中，Panavia 21水门汀在未使用底涂剂的试件和用Cesead不透明底涂剂处理的试件之间的粘结强度没有显示出任何显著差异。
