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.

本研究旨在评价选择性局部去骨对牙齿移动的影响。用镍钛弹簧将7周龄雄性Wistar大鼠的上颌第一磨牙向舌侧移动21天，测量牙齿移动量。无论是否存在选择性局部去皮质术，牙齿移动量均无统计学差异。组织学上，实验组和对照组之间没有病理学发现。
