Dent Mater J:四氟化钛处理过的玻璃纤维桩与树脂水门汀的粘接耐久性评估

2018-11-05 lishiting MedSci原创

这篇研究的目的是为了评估四氟化钛(TiF4)溶液对玻璃纤维桩与树脂水门汀的粘接效果影响。

这篇研究的目的是为了评估四氟化钛(TiF4)溶液对玻璃纤维桩与树脂水门汀的粘接效果影响。

研究将样本基于表面处理方法的不同随机分为8组。检测材料的弯曲特质和微拉伸粘接强度(µTBS)。所得数据使用two-way ANOVA和Tukey's post hoc检验进行统计学评估。

结果显示,与其他组相比,TiF4 (4 wt/v%-4 min)组呈现出最高的µTBS (p<0.05)。这个结果可以归咎于TiF4 (4 wt/v%-4 min)对于去除纤维桩表层树脂基质的能力,它可以为纤维桩提供更多暴露的表面积,以提高水门汀的微机械固位力。另外,表面处理并没有影响纤维桩的弯曲特质(p>0.05)。

结论:与其他表面处理相比,纤维桩经TiF4 (4 wt/v%-4 min)进行表面处理后对水门汀的粘接强度更高。
