摘要
目的:探讨预成金属桩、铸造金属桩、纤维桩在临床应用中的优缺点、远期保存率及美观效果。方法:将90例因龋坏和外伤导致的残根残冠患者随机分为3组,每组30例,修复后随访3年,对修复体的固位、外形完整性、微渗漏、牙龈牙根情况等多项指标进行综合评价。结果:预成金属桩核冠失败率较高,铸造金属桩核冠次之,纤维桩核冠最佳。结论:在残根残冠修复治疗中,双固化树脂粘接纤维桩冠修复是一种较好的选择,值得推广应用。
To investigate the advantages and disadvantages ot preexisting metal post, casting metal post and fiber post for clinical application ,the long term effectiveness and aesthetic satisfaction. Methods ：Nighty pa- tients with residual roots and crowns caused by dental caries and trauma were randomly divided into 3 groups, 30 pa tients in every group. Follow up 3 years after reparation for the restoration of retention,integrity,adaptation,micro leakage and the changes on gums and roots to carry out comprehensive evaluation.
