Analysis of the acceleration of the tooth movement by the selective bone decortication in rat.

本研究评估了选择性局部骨去皮对牙齿运动的影响。用Ni-Ti弹簧将7周龄雄性Wistar大鼠上第一磨牙移动至舌侧21 d，并测量牙齿移动量。无论是否存在选择性局部骨去皮，两组的牙齿移动量无统计学差异。组织学上，实验组与对照组无明显病理差异。

This study evaluated that the effects of selective local bone decortication on tooth movement. The upper first molars of 7-week-old male Wistar rats were moved to the lingual side using the Ni-Ti spring for 21 days and the amount of tooth movement was measured. There were no statistical differences in amount of tooth movement irrespective of the existence of selective local bone decortication. Histologically, there were no pathological findings between the experimental group and the control group.
