Abstract
An experimental study in dogs, in which 15 teeth were bodily moved and 9 teeth were tipped with the same amount of horizontal force. Less resorption was found with tipping, and less was found on the mesial root surfaces moved into the extraction sites than on the furcation side of the distal roots.
摘要
一项在狗身上进行的实验研究，其中15颗牙齿整体移动，9颗牙齿用相同大小的水平力倾斜移动。发现倾斜移动时的吸收较少，并且与远中牙根分叉侧相比，向拔牙位点移动的近中牙根表面的吸收更少。
