Midfacial fractures rank first concerning maxillofacial traumatology. Collisions of two heads or head to object are the main causes for these fractures. An investigation based on a transient simulation using the finite element method was performed. A biomechanical head model was created and tested. A transient collision of two heads was simulated. The results were compared to a typical real patient case. This comparison revealed an identical fracture pattern, which can be interpreted as a clinical match of the simulation. The results of this study show the validity of biomechanical investigations, which may serve as a method to better understand maxillofacial fracture patterns. These results will be used for the optimization of fracture therapy or trauma prevention in the future.
面中部骨折在颌面创伤学中排名第一。头部之间或头部与物体的碰撞是这些骨折的主要原因。使用有限元方法进行了基于瞬态模拟的研究。创建并测试了生物力学头部模型。模拟了两个头部的瞬态碰撞。将结果与典型的真实患者病例进行了比较。这种比较显示出相同的骨折模式，可以解释为模拟的临床匹配。这项研究的结果表明生物力学研究的有效性，这可以作为更好地了解颌面骨折模式的一种方法。这些结果将用于未来的骨折治疗或创伤预防的优化。
