[摘要]目的:探讨纤维桩核系统与氧化锆陶瓷桩核系统在治疗后牙残根残冠方面的临床效果,评价非金属桩核系统修复后牙残根残冠的治疗情况。方法:选择94例患者102颗后牙残根残冠,经完善根管治疗后,54颗采用纤维桩核系统修复,48颗采用氧化锆陶瓷桩核系统修复。随访2～3年后对结果进行评价。结果:本组94例(102颗患牙),纤维桩核系统修复成功率为90.7%,氧化锆陶瓷桩核系统修复成功率为89.6%。两种桩核冠修复方法在临床效果上无统计学差异(χ2检验:P>0.01)。结论:纤维桩核系统与氧化锆陶瓷桩核系统在修复后牙残根残冠方面无明显区别,均能满足临床要求。

Abstract:ObjectiveTo investigate the clinical observations about the management of treating posterior residual root and crown with Fiber post and core system or Zirconia ceramic post and core system,and evaluate the treatment conditions about Non-metallic post and core systems in posterior residual root and crown.Methods After treating root canal therapy,94 patients with 102 posterior residual root and crown were intered into observation.54 were treated with Fiber post and core system;the other 48 were treated with Zirconia ceramic post and core system. Evaluating the result after 2～3 years follow-up.ResultsThe success rate using Fiber post and core system was 90.7%;and the success rate was 89.6% by using Zirconia ceramic post and core system. The two methods were not different from each other in statistics(χ2test:P>0.01).ConclusionThere was no significant difference for treating posterior residual root and crown between Fiber post and core system and Zirconia ceramic post and core system.Both methods could meet the Clinical requirements.
Key words:non-metallic post and core systems;posterior residual root and crown,clinical observation
传统的金属桩核冠以其精确度高,固位力强,不易折断等优点被广泛应用于修复后牙的残根残冠。然而,随着磁共振成像技术(Magnetic Resonance Imaging,MIR)的广泛应用,因检查而拆除口内金属修复体的病例越来越多,非金属桩核系统由于其良好的物理性能和生物相容性,开始进入牙科领域 ......
