Finite element analysis (FEA) was employed to assess patterns of stress in bone adjacent to an implant after application of loads through an attached distal extension cantilever. Under all loading conditions, the highest stresses occurred at the distal cervical bone margin adjacent to the cantilever. In clinical studies, this is not consistently the site of the greatest bone changes seen radiographically. This suggests that extrapolation of FEA studies to clinical implantology should be approached with caution until further data become available on both mechanical properties of bone and patterns of bone remodelling induced by defined functional stresses in mandible and maxillae.
采用有限元分析（FEA）来评估通过附着的远端延伸悬臂施加负荷后种植体周围骨的应力模式。在所有加载条件下，最高应力出现在与悬臂相邻的远端颈部骨边缘。在临床研究中，这并非始终是影像学上可见最大骨变化的部位。这表明，在获得关于下颌骨和上颌骨中骨的力学性能以及由确定的功能应力引起的骨重塑模式的更多数据之前，将FEA研究外推至临床种植学应谨慎对待。
