摘　　要：背景:当冠部牙体组织大面积缺损单纯充填、全冠及嵌体疗效不佳时,桩核系统使残根、残冠的修复成为可能。目的:分析玻璃纤维桩和铸造金属桩在牙体缺损修复中的临床效果。方法:将106例患者共160颗患牙随机分为2组,经完善的根管治疗后,分别采用玻璃纤维桩(n=80)和铸造金属桩(n=80)制作桩核,金瓷冠修复,随访9-33个月,评价两组临床修复效果。结果与结论:玻璃纤维桩治疗成功78颗,桩松动2颗,治疗成功率98%;铸造金属桩治疗成功71颗,冠折1颗,根折4颗,桩脱落4颗,治疗成功率89%,两组治疗成功率比较差异有显著性意义(P<0.05)。表明玻璃纤维桩在牙体缺损修复中具有操作方便、色泽好且不易造成根折等优点,治疗效果优于金属铸造桩核修复。BACKGROUND：The post and core system for residual roots and crowns can achieve satisfactory effects, when fil ing restoration, ful crowns or inlay has poor effects. OBJECTIVE：To evaluate the clinical use of glass fiber post and metal post in the restoration of endodontical y treated teeth. METHODS：A total of 106 patients with 160 endodontical y treated teeth were selected and restored with glass fiber post （n=80 teeth） and metal post （n=80 teeth） fol owed by porcelain-fused-mental crown. The restorations were evaluated clinical y for 9 to 33 months. RESULTS AND CONCLUSION：Glass fiber post treatment for 78 teeth was effective and that for two teeth were failed, with a successful rate of 98%. Metal post restoration was effective in 71 teeth and failed in nine teeth including one tooth of crown fracture, four of root fracture and four of post loss, with a successful rate of 89%. There was statistical y significant difference between two groups （P〈0.05）. Glass fiber post is better in convenient handling and good color and reduced probability leading to root broken for dental restoration compared with metal post.
