摘要
目的研究固位增强温控变色石英纤维桩在后牙残根残冠修复中的效果。方法选择81例患者共109颗需修复的上下颌患牙,随机分为实验组和对照组,实验组62颗患牙,对照组47颗患牙,实验组采用固位增强温控变色石英纤维桩进行桩核修复,对照组采用金属桩核修复,观察16～24个月,通过临床和X线检查评价修复体的效果。结果实验组62颗患牙中,1颗桩冠脱落,1颗桩冠松动,成功率为96.8%。对照组47颗患牙中,4颗桩冠脱落,3颗桩冠松动,成功率为85.1%。实验组和对照组经卡方检验,两组之间有统计学意义(P<0.05)。结论固位增强温控变色石英纤维桩与金属桩相比有较高的成功率,是一种效果良好的后牙残根残冠修复方式。
Objective To evaluate the treatment outcome of the MACRO-LOCK POST ILLUSION in posterior teeth restorations after 16-24months.Methods Total 109 posterior teeth were chosed from 81 patients.They were divided into two groups.Experimental group were composed of 62 teeth.Control group were composed of 47 teeth.The teeth of experimental group were restored using the MACRO-LOCK POST ILLUSION.The teeth of control group were restored using the metal pole.Results were recorded after 16-24months.Results There was a crown fall off in the experimental group,and there was a crown loosened.The success rate was 96.8%.There were four crown fall off in the control group,and there were three crown loosened.The success rate was 85.1%.The experimental group and control group have the significant differences.Conclusion The MACRO-LOCK POST ILLUSION has a higher success rate than that of the metal pole,with a good effect of the posterior teeth residual root and crown restorations.
