摘　　要：目的对纤维桩与金属桩修复大面积牙体缺损的短期临床效果进行随访评价和比较。方法随机选取2011年5月至2013年5月于福建医科大学附属南平第一医院口腔科就诊的大面积牙体缺损、需要进行桩核冠修复的患者176例(共200颗患牙),随机分为两组,每组100颗患牙。试验组采用纤维桩+树脂核,然后进行烤瓷冠修复;对照组采用铸造钴铬金属桩核,然后进行烤瓷冠修复。治疗后随访观察2年,并评价临床效果。结果治疗2年后,试验组6例患牙纤维桩核脱落,2例发生牙龈炎症,临床成功率92%,脱落率6%;对照组发生5例牙龈炎症,3例根尖周炎,7例根折,成功率为85%,根折率7%,组间差异有统计学意义(P<0.05)。结论纤维桩核的脱落率高于金属桩核,但纤维桩核的根折发生率低,牙周及根尖周问题发生率两组相似。Objective To compare the clinical effects of fiber post-retained and metal post-retained restorations.MethodsTwo hundred teeth after root canal therapy from 176 patients were divided into 2groups randomly and each group consisted of 100 teeth.In the experimental group,teeth were restored with fiber post-resin core and porcelain crown,where cast metal-core and porcelain crown were used in the control group.The teeth were clinically examined regularly for 2years.The data were analyzed with Chi-square method.Results At the end of the 2-year follow-up,6fiber posts dislocated and 2teeth showed gingival inflammation in the experimental group,with a clinical success rate of 92%,the loss rate of 6%.5gingival inflammation cases,2periapical inflammation cases and 7cases of root fracture occurred in the metal post group,and the clinical success rate was 85%,root discount rate of 7%.There was statistical significance between the two groups（P〈0.05）.Conclusion The loss rate ogf fiber post-retained restoration is higher than the metal post-retained restorations,but the root discount rate is low,incidence of periodontal and periapical tissue similar in the two groups can be routinely used clinically instead of metal post-retained restoration.
