Angle mandible is one of the most common fractures in the mandible. Fractures of the angle mandible are one of the most problematic areas in the facial area due to the high frequency of complications and difficult access to the surgical site. Although there are many available miniplates and screws with several geometrical models for use in mandibular angle fractures, geometrical features of these materials and the optimal number and site of placement of plates have yet to be determined. An ideal plate should be durable and potent enough to endure the functional burden. This study employed 12 mandible replicas made of rigid polyurethane resin used with appropriately standardized measurements. A full-thickness fracture line was present on the angle of all mandible replicas. Four groups were formed. In the our study, mandibular angle fracture line was fixed with parallel two straight plates, a butterfly plate, a square plate, and a newly designed three-dimensional (3D) hourglass-shaped plate. Fixation was performed with a different miniplate in each group. Three samples were formed from each group. Each model was subjected to a compression test at a displacement-controlled loading. Loading was continued after maximum load was reached. The latter revealed a significant difference between the newly designed plate and the other three plates (p < 0.05). In conclusion, we suggest that with the newly designed plate, which was used for the first time in the our study and showed a greater resistance in mandibula fractures, designed plate application will be more effectively used in clinical practice.

角型下颌骨是下颌骨中最常见的骨折之一。下颌角骨折是面部区域中最成问题的区域之一，原因是并发症的发生频率很高且难以进入手术部位。尽管有许多可用的微型钢板和带有几种几何模型的螺钉可用于下颌角骨折，但这些材料的几何特征以及钢板的最佳放置数量和位置尚待确定。理想的板应耐用且强度足以承受功能负担。这项研究使用了12个由刚性聚氨酯树脂制成的下颌骨复制品，并使用了适当的标准化测量方法。在所有下颌骨复制品的角度上都出现了一条全厚度的断裂线。形成了四个小组。在我们的研究中 下颌角骨折线由平行的两个直板，蝶形板，方形板和新设计的三维（3D）沙漏形板固定。每组用不同的小孔板进行固定。每组形成三个样品。每个模型都在位移控制的负载下进行了压缩测试。达到最大负载后继续加载。后者显示了新设计的板与其他三个板之间的显着差异（每个模型都在位移控制的负载下进行了压缩测试。达到最大负载后继续加载。后者显示了新设计的板与其他三个板之间的显着差异（每个模型都在位移控制的负载下进行了压缩测试。达到最大负载后继续加载。后者显示了新设计的板与其他三个板之间的显着差异（p  ＜0.05）。总之，我们建议使用本研究中首次使用的新设计的钢板，并显示出对下颌骨骨折的更大抵抗力，设计的钢板应用将在临床实践中更有效地使用。
