The purpose of this study was to achieve strong and durable bonding between resin composites and titanium or cobalt-chromium alloy CAD/CAM frameworks in order veneered prostheses to withstand the severe environment in the oral cavity. Priming with 10-methacryloxydecyl dihydrogen phosphate (MDP) improved the bonding durability between veneering resin composite and a laser-sintered Co-Cr alloy the same as a cast Co-Cr alloy. Compared to cast Co-Cr alloy, laser-sintered Co-Cr alloy with retention devices provided better retention for resin composite-veneered prostheses. On the other hand titanium, the shear bond strengths were improved by additional etching with 45% H2SO4 and 15% HCl. These methods would be useful for reducing clinical complications, such as fracture or debonding of veneered resin composite from metal frameworks.

本研究的目的是在树脂复合材料与钛或钴铬合金CAD/CAM支架之间实现坚固耐用的粘结，以使贴面修复体能够承受口腔恶劣环境。用10-甲基丙烯氧基十烷基磷酸二氢(MDP)进行预涂处理，提高了贴面树脂复合材料与激光烧结钴铬合金之间的粘结耐久性。与铸造钴铬合金相比，带有固位装置的激光烧结钴铬合金对树脂复合贴面修复体具有更好的固位力。钛在45%H_2SO_4和15%HCl溶液中进行额外腐蚀后，剪切结合强度得到了提高。这些方法将有助于减少临床并发症，如贴面树脂复合材料断裂或从金属支架上剥离。
