低能量激光对大鼠牙移动后复发的影响
|
Abstract:
摘要 目的: 建立低能量激光及其他干预措施下大鼠牙移动后复发曲线,探讨低能量激光在正畸保持过程中的作用。方法: 60只Wistar大鼠随机分为4组,建立第一磨牙近中移动模型。4组分别进行以下处理:不施加任何措施、照射低能量激光、固定保持、固定保持加照射低能量激光,隔日进行3-shape三维扫描测量建立复发曲线,并对4组曲线进行重叠和描述性分析。结果: 低能量激光组大鼠磨牙移动复发率显著高于基线组,固定保持加低能量激光组复发率显著低于保持组(P<0.01)。与保持组相比,固定保持加低能量激光组复发周期明显缩短。结论: 大鼠磨牙主动矫治结束后,应用保持装置固定牙齿的位置并加以低能量激光照射,能够缩短保持期,减少复发
