The tooth movement of loaded premolars was investigated in four two-years-old beagle dogs under general anesthesia. Two supragingival registrations were performed to calculate the center of rotation in order to estimate the amount of tipping. Loads of 5 to 20 N were applied for two to four seconds. The amount of tipping was found to be load- and time-dependent. The discrepancy between these findings and the models of analytical mechanics were explained by bone bending in our experiments. Biology and localization of periodontal remodelling is supposed to be dependent on load magnitude, load duration and physical properties of all periodontal tissues including bone.
在全身麻醉下，对4只两岁的比格犬加载前磨牙的牙齿移动情况进行了研究。进行了两次龈上记录以计算旋转中心，从而估计倾斜量。施加5至20 N的力，持续两到四秒。发现倾斜量与力和时间有关。在我们的实验中，骨弯曲解释了这些发现与分析力学模型之间的差异。牙周组织重塑的生物学特性和定位被认为取决于力的大小、力的持续时间以及包括骨在内的所有牙周组织的物理特性。
