The purpose of this research was to analyze simultaneously the effect of 4 factors (metal conditioning, bonding agent, metal silicoating and water storage) on the tensile behavior of a Bis-GMA resin (microfilled) bonded Ni-Cr-Be alloy by analysis of variance with a multifactorial design. The results showed that metal surface conditioning and the presence of bonding agent had no effect. In contrast, water storage of 33 days or silicoating influenced significantly and positively the tensile bond strength. In addition, 2 significant factor-interactions were detected: a) between silicoating and water storage and b) between metal surface conditioning (sandblasting/etching) and silicoating. Metal sandblasting followed by silicoating reacted more favorably than the combination etching/silicoating. In all cases the mechanochemical adhesion (silicoating technique) resulted in a composite bond strength that was far superior to that of conventional, pure mechanical bonding.
本研究的目的是通过多因素设计的方差分析，同时分析4个因素（金属预处理、粘结剂、金属硅涂层和水储存）对双酚A缩水甘油醚甲基丙烯酸酯树脂（微填料）粘结镍铬铍合金拉伸性能的影响。结果表明，金属表面预处理和粘结剂的存在没有影响。相比之下，33天的水储存或硅涂层对拉伸粘结强度有显著的正向影响。此外，还检测到2个显著的因素相互作用：a）硅涂层和水储存之间；b）金属表面预处理（喷砂/蚀刻）和硅涂层之间。先进行金属喷砂再进行硅涂层的反应比蚀刻/硅涂层组合更有利。在所有情况下，机械化学粘结（硅涂层技术）产生的复合粘结强度远远优于传统的纯机械粘结。
