The mandible is the largest facial bone as well as the most commonly fractured bone in the maxillofacial region. Despite numerous studies conducted to identify optimal treatment modalities and plates configurations for intraoral and transoral approaches, no definitive conclusion has been reached. This study used finite element analysis (FEA) to assess 4 scenarios for treatment of an angle fracture (6-hole noncompression miniplate; 6-hole single plate/Champy's technique, 3D strut plate; 2 parallel 4-hole noncompression miniplates). Analysis included segmental displacement and Von Mises Stress evaluations of a 3D reconstruction of a human mandible. Von Mises Stress values for plates did not vary significantly among treatment groups. Moreover, no significant differences were observed in cumulative displacement of segments subjected to vertical and horizontal loads, with all treatment configurations demonstrating clinical acceptability.
下颌骨是最大的面骨，也是颌面部最常发生骨折的骨骼。尽管已经进行了大量研究以确定口内和经口入路的最佳治疗方式和接骨板配置，但尚未得出明确结论。本研究使用有限元分析（FEA）来评估治疗下颌角骨折的4种方案（6孔非加压微型接骨板；6孔单接骨板/尚皮技术、3D支撑接骨板；2块平行的4孔非加压微型接骨板）。分析包括对人类下颌骨三维重建的节段位移和冯·米塞斯应力评估。接骨板的冯·米塞斯应力值在各治疗组之间没有显著差异。此外，在承受垂直和水平载荷的节段的累积位移方面未观察到显著差异，所有治疗配置均显示出临床可接受性。
