两种前牙残根桩核冠修复技术的疗效比较

Comparison of clinical effect of two kinds of anterior teethresidual root and crown restoration technology

目的:对两种桩核冠技术用于残根残冠修复的临床疗效进行对比。方法:将256例残根残冠患者(432颗前牙)随机分为对照组(n=216)与实验组(n=216,对照组患者采用金属铸造核桩技术进行治疗,实验组患者采用玻璃纤维桩树脂核技术进行治疗,每隔6个月对患者进行再次检测。结果:1年期成功率无显著性差异(P>0.05),2年后成功率:对照组成功率86.1%,实验组成功率97.2%,有显著性差异(P<0.05),实验组治疗效果要优于对照组。结论:对于前牙残根残冠的修复,玻璃纤维桩核冠技术的临床疗效要比金属铸造桩核冠技术更加安全、高效,值得临床推广应用。

Ab Objective Two kinds of technology of pile nuclear crown for the clinical curative effect of restoration of residual root and crown were compared. Methods 256 cases of residual crown and residual root ofpatients （432 teeth） were randomly divided into control group （n = 216） and experimental group （n=216, control group patients with cast metal post coretechnology to carry on the treatment, the experimental group patients by using the nuclear technology of glass fiber post and resin treatment, every six months tested again for the patient. Results The success rate of one yearperiod with no significant difference （P〉0.05）,the rate of success after two years： in the control group, the success rate was 86.1%, the experimentalgroup, the success rate was 97.2%, there was significant difference （P〈0.05）,the treatment effect of the experimental group is better than control group. Conclusion For the repair of anterior residual crown and root,the clinical efficacy of glass fiber post core crown technology than the metal casting pile nuclear crown is safer and more efficient,it is worthy of clinical application.
