The purpose of this study was to investigate the effect of a 4-MET- and 10-MDP-based primer on the bond strength of two resin cements (SuperBond C&B, Sun Medical; Panavia Fluoro Cement, Kuraray) to titanium (Ti). Ti plates were treated with six experimental primers consisting of, respectively, 10-MDP and 4-MET in concentrations of 0.1, 1 and 10wt%, or were kept untreated (control). The highest tensile bond strength of Panavia Fluoro Cement to Ti was obtained when the Ti surface was pre-treated with 10wt% 10-MDP and was significantly higher than that when a lower concentrated 10-MDP-based primer or any 4-MET-based primer was used. On the contrary, no significant difference in tensile bond strength of SuperBond C&B was found for the untreated and six pre-treated Ti surfaces, although pre-treatment with each 10-MDP-based primer resulted in a higher tensile bond strength as compared to any 4-MET pre-treatment. Altogether, the data obtained strongly suggest that 10-MDP is effective to improve the adhesive performance of resin to titanium.
本研究的目的是调查一种基于4 - MET和10 - MDP的底漆对两种树脂水门汀（SuperBond C&B，日进医疗株式会社；Panavia Fluoro Cement，可乐丽株式会社）与钛（Ti）之间粘结强度的影响。将钛板用六种实验性底漆进行处理，这六种底漆分别由浓度为0.1%、1%和10%（重量）的10 - MDP和4 - MET组成，或者不进行处理（对照）。当钛表面用10%（重量）的10 - MDP进行预处理时，Panavia Fluoro Cement与钛之间获得了最高的拉伸粘结强度，且显著高于使用低浓度的基于10 - MDP的底漆或任何基于4 - MET的底漆时的强度。相反，对于未处理的和六种预处理的钛表面，SuperBond C&B的拉伸粘结强度没有显著差异，尽管与任何基于4 - MET的预处理相比，用每种基于10 - MDP的底漆进行预处理都导致了更高的拉伸粘结强度。总之，所获得的数据有力地表明，10 - MDP可有效提高树脂与钛的粘结性能。
