| 摘 要： | 目的：建立双侧下颌骨牵引成骨的三维有限元模型，探讨牵引器不同放置方位对骨一牵引器界面的生物力学影响。方法：模拟牵引器放置平行于下颌骨体部及平行于牵引轴方向两种状况，分析下颌骨牵引延长不同工况下骨一牵引器界面位移、综合应力情况。结果：牵引器放置平行于下颌骨体部时，骨一牵引器界面侧向位移、综合应力均大于牵引器放置平行于牵引轴方向的情况。结论：实验结果提示牵引器应尽量放置平行于牵引轴方向，避免可能发生的不良并发症。 |

| Abstract: | Objective: The purpose of this study was to construct the three-dimensional finite element model(FEM)of bilateral mandible distraction osteogenesis,so as to explore the biomechanical effects of the orientation of distractors on the distractors-bone interface.Methods: In simulating the orientation of distractors either parallel to the body of the mandible or parallel to the axis of distraction,by which the mandible was lengthened,we analyzed the displacement and stress distribution on the distractors-bone in... |
