力学自适应骨重建的数值模拟结果与临床图像进行了比较。将多个人类受试者的锥形束计算机断层扫描（CBCT）图像叠加，以获得支持侧切牙的下颌骨内的连续骨密度空间分布图。使用有限元分析计算正常咀嚼力和咬合力下骨中的应变能密度。采用骨重建算法计算平衡状态下的骨密度分布。对每一个骨小梁单元，通过数值模拟计算的骨密度与通过图像分析获得的骨密度之间进行线性回归分析。结果显示出密切的相关系数为0.8499协议。咬合力通过牙根传递到周围的骨，从而刺激牙根附近的高骨小梁密度。下颌骨矢状面上的弯矩和扭矩导致靠近下颌骨中心的骨密度低于靠近下颌骨边缘的骨密度。研究结果提供了一种新的方法来比较自适应骨重建模拟的结果与实验数据，也提供了模型参数，以预测周围的骨密度分布的牙种植体，取代牙齿。
The results of numerical simulation of mechanically adaptive bone remodeling have been compared with clinical images. Cone beam computed tomography (CBCT) images of multiple human subjects were superimposed to obtain a continuous bone density spatial distribution map inside the mandible supporting the lateral incisor. Strain energy density in the bone under normal chewing and biting forces was computed using finite element analysis. A bone remodeling algorithm was implemented to compute the bone density distribution at equilibrium. Linear regression analysis was performed between the bone density computed by numerical simulation and that obtained from image analysis, for every trabecular bone element. The results exhibited close agreement with a coefficient of correlation of 0.8499. The bite forces were transmitted through tooth roots to the surrounding bone, thus stimulating high trabecular bone density near the roots. The bending and torsion moments on the sagittal section of the mandible resulted in lower bone density near the center than those towards the edge of the mandible. The results provide a new method to compare the results of adaptive bone remodeling simulation with experimental data, and also provide model parameters to predict the bone density distribution surrounding a dental implant that replaced the tooth.
