A study was carried out on mechanical stress at the resection site in mandibles undergoing segmental resections. A computer simulation model was used to study particularly the effect of various radii of the posterior resection corners and the effect of elimination of muscle action. It was found that an enlarged radius of the resection corner in conjunction with coronoid process resection on the ipsilateral side offers the best condition to prevent fracture of the mandible.
对接受节段性切除的下颌骨切除部位的机械应力进行了一项研究。使用计算机模拟模型特别研究了后切除角的不同半径的影响以及消除肌肉作用的影响。结果发现，切除角半径增大并结合同侧冠突切除可为防止下颌骨骨折提供最佳条件。
