Adhesive bonding between resin composites and laser-sinterd or machine-milled metal frameworks

本研究的目的是实现树脂复合材料与钛或钴铬合金CAD/CAM框架之间牢固耐用的结合，以使贴面假体能够承受口腔内的恶劣环境。10-甲基丙烯氧基十二烷基磷酸二氢（MDP）底漆提高了贴面树脂复合材料与激光烧结Co-Cr合金之间的结合耐久性，与铸造Co-Cr合金相同。与铸造Co-Cr合金相比，激光烧结带固位装置的Co-Cr合金为树脂复合贴面修复体提供了更好的固位效果。另一方面，用45%的H2SO4和15%的HCl进行蚀刻，可以提高钛的剪切结合强度。这些方法将有助于减少临床并发症，如骨折或脱粘贴面树脂复合材料从金属框架。

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.
