玻璃纤维桩用于前牙残根残冠修复的临床研究

目的探讨玻璃纤维桩用于前牙残根残冠修复的临床效果。方法选择前牙残根残冠患者104例，共192颗患牙，经过完善的根管处理后，均用桩核冠修复。将患者随机分为观察组和对照组。观察组54例，共96颗患牙，采用玻璃纤维桩；对照组50例，共96颗患牙，采用铸造金属桩，治疗后随访2年，观察治疗成功率。结果所有患者均完成治疗，随访2年时间，观察组成功率为96．9％，对照组成功率为87．5％，差异有统计学意义（P〈0．05）；两组失败病例中以下颌牙失败多见。结论玻璃纤维桩修复前牙残根残冠近期临床修复效果较好，但长期临床疗效还需要进一步研究。

The Clinical Research of Glass Fiber Post to Repair Front Teeth Residual Roots and Crowns

Objective To discuss the clinical effect of glass fiber post to repair front teeth residual roots and crowns. Methods To choose 104 cases front teeth with the residual roots and crowns,192 teeth,and after the perfect root canal treatment,all used post-core crown restoration. The patients were randomly divided into research group and control group：the research group of 54 patients,96 teeth ,used glass fiber posts ,and the control group of 50 patients ,96 teeth ,used cast metal posts. Follow-up two years after treatment, success rates of treatment were observed. Results All patients completed treatment. Follow-up two years,the success rate of the re- search group was 96.9% and that of the control group was 87.5%,and the difference was statistically significant （P〈0.05）. The main failure of two groups was in the mandibular teeth. Conclusion The clinical repair effect of glass fiber post repairing front teeth resid- ual roots and crowns is good in recently,but the long-term clinical efficacy needs to be studied.
