摘要
目的：应用平行柱状根管桩修复牙冠缺损，观察临床疗效，并与传统根管桩技术进行比较。方法：自2000年8月-2005年8月，选取门诊129名前牙冠缺损患者，共184颗患牙，分别采用平行柱状根管桩、铸造锥形根管桩、锥形螺纹桩进行修复治疗。结果：经5年临床应用与追踪观察，平行柱状根管桩的修复效果（成功率97．75％）明显优于其他两种方法。结论：在残根、残冠的保留治疗中，应用平行柱状根管桩修复牙冠缺损，可取得良好的修复效果。
Objective： To study the clinical restorative effects of the different dowel systems, and evaluate the function of parallel- sided post system compared to the tapered cast post and the pre- fabricated thread post. Method： 184 anterior teeth of 129 patients with crown defects were chosen and randomly divided into three groups, and were respectively restored with parapost system, tapered cast post , and pre - fabricated thread post. Results： The results of five - year follow - up study showed that the parapost system gained higher successful rate of 97.75% with 2 cases failed, while tapered cast post achieved 87.72% and pre- fabricated thread post performed 85.11%. Conclusion： Because of the prior features, the parallel - sided post system is a proper technique to deal with crown defects of the teeth, and it could develop satisfactory restorations.
