摘要 目的:比较铸造金属桩核与玻璃纤维桩核修复上颌前牙残冠残根的临床效果。方法:随机选取16~50岁的病例128例共150个上颌前牙残冠残根进行修复,其中64个牙制作铸造金属桩核,86个牙制作玻璃纤维桩核,桩核完成后均行烤瓷熔附金属全冠修复。结果:经过0.5~2.5年的随访观察,铸造金属桩组出现7个牙根折,3个牙修复体松动脱落,1个牙慢性尖周炎复发,成功率为82.81%。玻璃纤维桩组出现2个牙根折,1个牙修复体松动脱落,1个牙窦道溢脓,成功率为95.35%。经χ2检验,两组的差异有显著性。结论:玻璃纤维桩核修复上颌前牙残冠残根具有更好的临床效果。 Objective: To compare the clinical effect between metal cast post core and glass fiber-reinforced post core applied in the restoration of residual crown and root of upper anterior tooth. Method: Among 150 teeth with residual crown and root of upper anterior tooth, 64 teeth were restored with metal cast post core and 86 teeth were restored with glass fiberreinforced post core, then all cases were restored with porcelain fused metal crown.Result: With 0.5 to 2.5 years following study,each 1 case failed for recurrent chronic apicitis.7 teeth failed for root fracture,3 tooth failed for crown loose in the metal cast post core group with 82.81% success rate. 2 teeth failed for root fracture, 1 tooth failed for crown loose in the glass fiber-reinforced post core group with 95.35% success rate. The success rate has significant difference with X^2-test. Conclusion: Glass fiber-reinforced post and light-cure resin core has better clinical effect than metal cast post core used to restore residual crown and root of upper anterior tooth.
