选择１３例对称拔除第一双尖牙的样本进行配对实验，以１５０ｇ的力拉尖牙向远中移动。实验侧行局部超声波作用，每日１次，每次１０分钟，１４天为１疗程。经过１疗程的观察，发现实验侧尖牙移动速度比对照侧提高２８．６７％，作者推测：由于超声波特有的生物学效应，活化了局部牙周组织细胞，加速牙周组织的改建，从而加快正畸牙齿的移动。
Select 13 cases of symmetrical removal of the first pair of canine samples paired experiment to 150g of force to move farther canine. Experimental side effects of local ultrasound, 1 day, every 10 minutes, 14 days for a course of treatment. After a course of treatment, it was found that the canine movement velocity was 28.67% higher than that of the control side. The author speculated that due to the unique biological effects of ultrasound, local periodontal tissue cells were activated to accelerate the reconstruction of periodontal tissues and thus accelerate Orthodontic tooth movement.
