目的:探讨玻璃纤维桩在前牙残根残冠修复中的临床应用效果。方法:将154颗经过完善根管治疗的前牙随机分为两组,A组77例植入玻璃纤维桩后行烤瓷冠修复,B组77例植入金属铸造桩核行烤瓷冠修复,进行0.5～2年随访。结果:A组76例修复体及基牙完好,成功率为98.70%;B组70例修复体及基牙完好,修复成功率90.90%。结论:运用玻璃纤维桩进行前牙残根残冠修复,具有操作方便,简捷及良好的生物相容性,能有效防止根折和牙周病变。
Objective: To investigate the clinical application of glass fiber posts in the repair of anterior residual root and crown. Methods: One hundred and four anterior teeth treated with perfecting root canal were randomly divided into two groups. 77 cases in group A were implanted with glass fiber post, followed by porcelain crown restoration. In group B, 77 cases were implanted with metal casting post and porcelain crown , For 0.5 to 2 years follow-up. Results: In group A, 76 cases of prosthesis and abutment were intact with a success rate of 98.70%. In group B, 70 cases of prosthesis and abutment were intact with a success rate of 90.90%. Conclusion: The use of glass fiber post-crown restoration of anterior residual root, with easy operation, simple and good biocompatibility, can effectively prevent root and periodontal lesions.
