A controlled pulsating-force system for the orthodontic movement of teeth was designed and its biologic effects were examined, with the dog serving as an experimental model. This system was applied to the maxillary right second premolar while a continuous force was delivered to the maxillary left second premolar. After a 12-day experimental period in which pulsating forces were used, the amount of tooth movement and the radiographic and histologic changes were comparable to those produced by continuous force. These preliminary data indicate that forces of greater magnitude and duration will be necessary to more fully characterize the potential advantages of a pulsating orthodontic force.
设计了一种用于牙齿正畸移动的可控脉动力量系统,并以狗作为实验模型研究其生物学效应。该系统应用于上颌右侧第二前磨牙,同时对上颌左侧第二前磨牙施加持续力。在使用脉动力量的12天实验期后,牙齿移动量以及影像学和组织学变化与持续力所产生的变化相当。这些初步数据表明,需要更大强度和持续时间的力才能更全面地描述脉动正畸力的潜在优势。
