Transient finite element analysis of a traumatic fracture of the zygomatic bone caused by a head collision

Int J Oral Maxillofac Surg. 2012 Jan;41(1):66-73. doi: 10.1016/j.ijom.2011.09.004. Epub 2011 Oct 12.

Abstract

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.
