采用三维有限元分析方法，比较直线形和三角形标记螺钉固定双侧下颌升支矢状劈开截骨术，以及双、单六孔微型钢板加单皮质螺钉固定后的生物力学稳定性。三维有限元模型包含122，717个单元和25，048个节点。在远中段上模拟后牙合蟾蜍。采用MSC Marc软件对节段和固定装置的应力场进行了计算。我们的结论是，三角形标签螺钉配置或双微型板导致更好的稳定性和塔附近的截骨比线性拉力螺钉或单斜微型板的机械应力。(c)2004年英国口腔颌面外科医师协会。由爱思唯尔有限公司出版。保留所有权利。
We used three-dimensional finite element analysis to compare the biomechanical stability of bilateral sagittal split ramus osteotomies fixed by tag screws with linear and triangular configuration, and double or single six-hole miniplates with monocortical screws after set-back operation. The three-dimensional finite element model contained 122,717 elements and 25,048 nodes. Posterior occlusal toads were simulated on the distal segments. MSC Marc software was used to calculate the stress fields on both the segments and the fixing appliances. We conclude that either triangular tag screw configuration or double miniplates led to better stability and tower mechanical stresses near the osteotomy than the linear lag screws or single oblique miniplates.
