The objective of this study was to develop a 3-dimensional finite element model (FEM) to formulate biomechanical justification of the positioning of different plates to achieve stable fixation of a fractured mandible. Miniplate systems that give acceptable levels of rigidity were investigated, and recommendations about miniplate location, orientation, and type selection are made. A fracture near the body region was bridged with a variety of commonly used plate configurations. Number, positioning and type of the plate system parameters. The results of this fracture model support the advantage of 2-plate systems. Using a longer plate in the superior position and a shorter one in the inferior position produced a more stable condition. Number of screws or length of the miniplate had no significant effect on the stability of fractured segments. The results obtained from this study offer the choice of a particular plate size, thickness, design, or configuration for application and thus provide information for clinical use.
本研究的目的是建立一个三维有限元模型（FEM），以阐述不同接骨板定位实现下颌骨骨折稳定固定的生物力学依据。对具有可接受刚度水平的微型接骨板系统进行了研究，并就微型接骨板的位置、方向和类型选择提出了建议。用各种常用的接骨板配置对靠近体部区域的骨折进行桥接。接骨板系统参数的数量、定位和类型。该骨折模型的结果支持双接骨板系统的优势。在上部位置使用较长的接骨板，在下部位置使用较短的接骨板可产生更稳定的状态。螺钉数量或微型接骨板的长度对骨折段的稳定性没有显著影响。本研究获得的结果为应用提供了特定接骨板尺寸、厚度、设计或配置的选择，从而为临床应用提供信息。
