本研究的目的是研究自聚合树脂与尼龙义齿基托聚合物（Lucitone FRS：LT）在不同条件下的剪切粘结强度。表面处理，以及与热聚合树脂和聚碳酸酯聚合物相比的结果。根据表面处理方法将样本分为五组：抛光（#600）、喷砂、粘合剂底漆应用（树脂底漆）、喷砂+粘合剂底漆应用和摩擦化学涂层（Rocatec系统）。然后，对试样进行剪切结合强度试验，并使用电子探针显微分析仪（EPMA）测定Si浓度。在剪切粘结强度方面，摩擦化学涂层组显著高于其他组。在EPAIA结果中，发现具有摩擦化学涂层的LT表面覆盖有二氧化硅膜。因此，本研究的结果表明，Rocatec系统的二氧化硅涂层可有效提高尼龙义齿基托聚合物与自聚合修复树脂的粘结强度。
This study, aimed to investigate the shear bond strength of an autopolymerizing resin to a nylon denture base polymer (Lucitone FRS: LT) subjected to different. surface treatments, and the results thereof compared with a heat-polymerizing resin and a polycarbonate polymer. Specimens were divided into five groups according to the surface treatment method: polishing (#600), sandblasting, adhesive primer application (resin primer), sandblasting + adhesive primer application, and tribochemical coating (Rocatec system). Following which, specimens were subjected to a shear bond strength test and Si concentrations were measured using an electron probe microanalyzer (EPMA). On shear bond strength, that of LT with tribochemical coating was significantly higher than the other groups. On EPAIA results, the surface of LT with tribochemical coating was found to be covered with a silica film. Therefore, findings in this study indicated that silica-coating by Rocatec system was effective in improving the bond strength of nylon denture base polymer to autopolymerizing repair resin.
