摘　　要：目的观察RTD MACRO-LOCK POST固位增强型石英纤维桩与金属桩修复上颌前牙残冠的临床疗效。方法选取上颌前牙牙体缺损患者200例,随机分为两组,分别采用RTD MACRO-LOCK POST固位增强型石英纤维桩与金属桩进行桩核冠修复,随访观察3年。结果纤维桩组患者修复后6个月临床成功率与金属桩组无明显区别(P>0.05),修复后3年临床成功率高于金属桩组(P<0.05)。结论在正确选择适应证前提下,RTD MACRO-LOCK POST固位增强型石英纤维桩修复效果优于金属桩。Objective Clinical effect contrast between RTD MACRO-LOCK POST retentive enhanced quartz fiber post and metal post in restoration of residual crown of maxillary anterior teeth. Methods Select 200 cases with max- illary anterior teeth defect, randomly divide into 2 groups. Use RTD MACRO-LOCK POST retentive enhanced quartz fiber post and metal post for post core crown, observe and compare the clinical effects after 3 years. Results There is no significant difference between 2 groups after 6 months （P〉0.05）. The clinical success rate of fiber post group is higher than that of the metal post group after 3 years （P〈0.05）. Conclusion With correct choice of indications, the clinical effect of RTD MACRO-LOCK POST retentive enhanced quartz fiber post is better than that of the metal post.
