两种不同粘接系统在玻璃纤维桩修复中的临床效果

Clinical evaluation of retention strength of two different adhesive systems on glass fiber-reinforced posts

目的比较两种不同粘接系统用于玻璃纤维桩核修复的临床效果。方法选取136颗已行根管治疗的患牙随机分为自酸蚀Multilink N和自粘接Rely X Unicem两组,行玻璃纤维桩+全冠修复。分别在修复后进行随访观察,比较两组患牙的临床修复成功率。结果修复后6、12、24月,两组成功率均在97%以上,且两组间比较差异无统计学意义(P>0.05)。结论 Multilink N自酸蚀树脂水门汀和RelyX Unicem自粘接树脂水门汀用于粘接纤维桩均能获得良好的临床修复效果。

Objective To evaluate the clinical effect of two different resin cements on the glass fiber-reinforced posts.Methods One hundred and thirty-six teeth were randomly divided into two groups,with sixty?eight in each.Group A used Multilink N self?etch system and group B used RelyX Unicem self?adhesive system to bond fiber posts.Follow?up examinations took place at6,12and24months after the placement.Results The success ratios of two groups were all97%above and there was no significant difference between two groups(P>0.05).Conclustion Multilink N self?etch system and RelyX Unicem self?adhesive system all have good effect on glass fibereinforced posts bonding.
