纤维桩辅桩在前牙喇叭口状残根修复中的临床应用

Application of auxiliary pole in esthetic prosthodontic treatment of posterior residual root

目的研究纤维桩和纤维桩辅桩在前牙喇叭口状残根修复中的临床效果。方法选择51例患者的98颗需修复的上前牙为研究对象,随机分为实验组和对照组,实验组56颗患牙,对照组42颗患牙。实验组采用D.T.Light-Post纤维桩和纤维桩辅桩进行桩核冠修复,对照组仅采用纤维桩进行桩核冠修复,观察18个月,通过临床和X线检查评价修复体的临床效果。结果实验组56颗患牙的桩冠无脱落或松动,成功率为100.0%。对照组42颗患牙的桩冠中,1颗桩冠脱落,4颗桩冠松动,成功率为88.1%。实验组和对照组经卡方检验,2组差异有统计学意义。结论 D.T.Light-Post纤维桩和纤维桩辅桩是一种效果良好的前牙喇叭口状残根的修复方式。

Objective To evaluate the treatment outcome of the auxiliary pole in anterior teeth restorations. Methods 98 anterior teeth were chose from 51 patients. They were divided into two groups. Experimental group were composed of 56 teeth. Control group were composed of 42 teeth. The teeth of experimental group were restored using the D.T.Light-Post and auxiliary pole. The teeth of control group were restored just using the D.T.Light-Post. Clinical results and X-ray were recorded after 18 months. Results There was no post crown fall off or loosed in the experimental group,the successful rate was 100.0%. There were one post crown fall off in the control group,and four post crown loosed,the successful rate was 88.1%. The experimental group and control group have the significant differences. Conclusion The D.T.Light-Post and auxiliary pole have good effect on the anterior teeth of residual root.
