非金属桩核系统修复后牙残根残冠的临床观察

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。

Clinical observations about the management of treating posterior residual root and crown with Non-metallic post and core systems

Objective To 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.Results The 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（χ^2test：P〉0.01）.Conclusion There 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.
