摘　　要：目的观察旋转脉动磁场对兔正畸牙齿移动的影响.方法25只体重为1.0~1.5 kg的健康新西兰大耳白兔按每组5只随机分为实验1,3,5,7,14 d.2%戊巴比妥钠麻醉下于双侧上颌第一磨牙与切牙间拴结不锈钢螺簧,施力80 g,左侧只加力为对照组,右侧加力并加旋转脉动磁场为实验组,观察正畸牙槽骨的改建情况并测量牙齿移动距离.结果实验组正畸牙齿移动距离明显大于对照组(p<0.05),光镜观察显示实验组牙槽骨的改建活跃,张力侧骨形成的量明显高于对照组.结论旋转脉动磁场可促进正畸牙槽骨改建.Objective to investigate the effect of rotating pulsed magnetic field on orthodontic tooth movement in rabbits.Methods 25 white rabbits was randomly divided into 5 groups of 1,3,5,7 and 14 days.Under anesthesia condition by 2% pentobarbital sodium,the stainless coil springs were fixed between the first maxillary molar and the incisor producing the force of 80 g.The Experimental group was treated by rotating pulsed magnetic field and the force,and the control group was only treated by the force.Later,the his...
