本研究的目的是研究基于4-MET和10-MDP的底漆对两种树脂骨水泥（SuperBond C&B，Sun Medical; Panavia Fluoro Cement，Kuraray）与钛（Ti）的粘结强度的影响。用分别由浓度为0.1、1和10wt%的10-MDP和4-MET组成的六种实验引物处理Ti板，或保持未处理（对照）。当钛表面用10wt%10-MDP预处理时，Panavia氟骨水泥与钛的拉伸粘结强度最高，并且显著高于使用较低浓度的10-MDP基底漆或任何4-MET基底漆时的拉伸粘结强度。相反，对于未处理的和六个预处理的Ti表面，未发现SuperBond C&B的拉伸粘结强度的显著差异，尽管与任何4-MET预处理相比，用每种基于10-MDP的底漆预处理导致更高的拉伸粘结强度。总之，所获得的数据有力地表明，10-MDP是有效的，以改善树脂的粘接性能的钛。
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.
