纤维桩辅桩在前牙残根残冠修复中的临床应用

Application of Auxiliary Pole in Esthetic Prosthodontic Treatment of Posterior Residual Root and Crown teeth

目的研究纤维桩辅桩在前牙残根残冠修复中的效果。方法选择84例患者共142颗需修复的上前患牙,随机分为实验组和对照组,实验组85颗患牙,对照组57颗患牙,实验组采用固位增强温控变色石英纤维桩加纤维桩辅桩进行桩核修复,对照组采用固位增强温控变色石英纤维桩修复,观察6~15个月,通过临床和X线检查评价修复体的效果。结果实验组85颗患牙中,所有桩冠无脱落或松动,成功率为100.0%。对照组57颗患牙中,1颗桩冠脱落,3颗桩冠松动,成功率为92.9%。实验组和对照组经卡方检验,两组之间差异有统计学意义（P〈0.05）。结论固位增强温控变色石英纤维桩加纤维桩辅桩是一种效果良好的前牙残根残冠修复方式。

Objective To evaluate the treatment outcome of the auxiliary pole in posterior teeth restorations after 6~15months.Methods Total 142 posterior teeth were chosed from 84 patients.They were divided into two groups.Experimental group were composed of 85 teeth.Control group were composed of 57 teeth.The teeth of experimental group were restored using the MACRO-LOCK POST ILLUSION and Auxiliary pole.The teeth of control group were restored using the MACRO-LOCK POST ILLUSION.Results were recorded after 6-15months.Results There was no a crown fall off or loosened in the experimental group,The success rate was 100.0%.There were one crown fall off in the control group,and there were three crown loosened.The success rate was 92.9%.The experimental group and control group have the significant differences.Conclusion The MACRO-LOCK POST ILLUSION and Auxiliary pole is a good effect of the posterior teeth residual root and crown restorations.
