骨适应的机制之一是组织水平材料特性的改变。我们假设肺泡过程压痕模量的改变是对局部机械环境的适应性反应。从6只成年雄性比格犬身上获得了48个代表上、下颌骨前后区域的标本。估计了牙槽骨本身和更远的骨皮质骨的压痕特性。将骨型进一步划分为冠状、中、尖3个区，每个区牙支撑骨形成27个凹痕。颌骨的压痕模量（上颌骨/下颌骨）、位置（前/后）和骨类型（牙槽骨与皮质骨）有显著差异（p < 0.001）。然而，存在统计上的相互作用，这妨碍了对结果的简单解释。相对刚度的分布提供了更好的理解骨适应在牙槽过程。
One mechanism of bone adaptation is alteration in tissue level material properties. We hypothesized that alteration in the indentation modulus of the alveolar process is an adaptive response to the localized mechanical environment. Forty-eight specimens representing anterior and posterior regions of the maxilla and mandible were obtained from 6 mature male beagle dogs. The indentation properties of the alveolar bone proper and more distant osteonal cortical bone were estimated. The bone types were further divided into 3 regions ( coronal, middle, and apical), with 27 indents being made in each region of tooth-supporting bone. There was a significant difference (p < 0.001) in the indentation moduli of the jaws (maxilla/mandible), location (anterior/posterior), and bone type ( alveolar bone proper vs. cortical bone). However, statistical interactions exist which preclude the simple interpretation of results. The distribution of relative stiffness provides a better understanding of bone adaptations in the alveolar process.
