摘　　要：目的探讨玻璃纤维桩核与金属烤瓷全冠修复后牙残冠、残根的临床效果。方法选取70例19～58岁后牙残冠、残根患者共计155颗患牙。经过完善的根管治疗后随机分为2组,实验组40例患者共80颗患牙植入玻璃纤维桩核,对照组30例患者共75颗患牙用金属铸造桩核修复。2组患者均用金属烤瓷全冠恢复牙体外形。观察2组患者的修复体形态、功能和成功率,并用SPSS 13.0软件包对2组修复体的成功率进行χ2检验。结果随访24个月实验组共76颗牙咀嚼功能良好,无不适主诉,修复体牢固(成功率)为95.00%,而对照组75颗牙获得88.00%的成功率,2组差异有统计学意义(P<0.05)。结论玻璃纤维桩核修复残冠、残根是一种操作简便、省时、临床疗效好的修复方法。Objective To evaluate the clinical effect of glass fiber - reinforced post core applied in the restoration of premolar or mo- lar residual crown and root. Methods All 155 residual crown and root of posterior teeth from 70 patients, aged from 19 to 58 years, were in- cluded in the study. Among 155 teeth, 80 teeth in the experimental group were restored with glass fiber -reinforced post core, while the other 75 teeth in the control group were restored with metal cast post core. All the teeth were then restored with porcelain fused metal crown. The esthetical property, function, and survival rate of the prostheses were observed. The data were analyzed with SPSS 13.0 software package for X2 test. Results The prostheses were followed up in this clinical study for a period of up to 24 months. In the experimental group, there were a total of 76 teeth with excellent chewing function, no complaint of discomfort, no debounding, and no gingivitis or periapical periodontitis. The success rate of the experimental group was 95%, while that of the control group was 88%. The difference of the success rate between two groups was statistically significant （ P 〈 0.05 ）. Conclusion Restoration of residual crown and root with glass fiber - reinforced post core is easy to operate, time - saving and effective.
