目的 :比较2种不同形状的纤维桩在前磨牙残冠中的修复效果,为临床前磨牙纤维桩修复提供经验。方法 :选取53例需行纤维桩修复的前磨牙残冠,随机分为平行纤维桩组和双锥度纤维桩组,分别比较2组的修复效果以及操作的难易程度。采用SPSS 13.0软件包对数据进行统计学分析。结果:平行桩组与双锥度组成功率之间差异无统计学意义。平行桩组有4例发生并发症,双锥度组有1例发生并发症。结论:平行纤维桩和双锥度纤维桩在修复前磨牙残根的效果无显著差别,但双锥度纤维桩操作过程中并发症发生率低于平行桩。
OBJECTIVE: To compare the repair effects of two different shapes of fiber posts in the crown of premolar teeth and provide experience for the repair of premolar fiber post. Methods: Fifty-three crown remnant of premolar tooth repairs with fiber post were selected and randomly divided into parallel fiber pile group and double-taper fiber pile group. The repair effect and the ease of operation of the two groups were compared respectively. Data were statistically analyzed using SPSS 13.0 software package. Results: There was no significant difference in the compositional power between parallel pile and double cone. Complications were found in 4 cases in parallel pile group and in 1 case in double cone group. CONCLUSION: There is no significant difference between the parallel fiber posts and double-taper fiber posts in repairing the remnants of premolar teeth. However, the incidence of complications during the operation of double-taper fiber posts is lower than that of parallel piles.
