从7只恒河猴中取出86颗牙齿。个别牙齿，以及几个相邻的牙齿，被删除，提供标本从一个星期到一年后extraction.Clinical照片和组织学标本显示，无牙嵴的吸收发生更迅速地在顶部的颊牙槽骨板的结果，八个星期后，在剩余的脊位于lingually和palatally以及apically在其原来的位置。因此，当沿牙槽嵴沿着测量时，剩余牙槽嵴的长度与原始牙槽嵴的长度相比大大减少。位于沿着牙槽骨外壁的肌肉附着体在颌骨的几个区域被固定，以限制牙槽嵴在根尖方向的吸收水平。
Eighty-six teeth were extracted from sevenMacaca rhesusmonkeys. Individual teeth, as well as several adjacent teeth, were removed providing specimens from one week up to one year after extraction.Clinical photographs and histologic specimens showed that the resorption of the edentulous ridge occurred more rapidly at the crest of the buccal alveolar plate resulting, after eight weeks, in residual ridges with crests located lingually and palatally as well as apically in relation to their original position. Thus, the length of the residual ridge when measured along the crest is considerably reduced in comparison with the original length.The muscle attachments located along the external bony walls of the socket at several regions of the jawsseemedto limit the level of resorption of the alveolar crest in an apical direction.
