Finite element analysis of external loads resulting in fronto-orbitonasal fractures
Journal Title: Journal of Stomatology (Czasopismo Stomatologiczne) - Year 2010, Vol 63, Issue 10
Abstract
Introduction: Craniofacial skeleton is a structure that remains partly unrecognized as far as the properties of its mechanical strength are concerned. The evaluation of the craniofacial resistance to external loads and stresses in a live person is practically impossible in clinical conditions. Thus, it seems valid to implement computer-aided methods of virtual design in the clinical practice, methods that have been so effectively applied to technical sciences.Aim of the study: By means of the FEM technique to evaluate the maximal concentration of loads potentially resulting in fractures of the craniofacial skeleton that manifest themselves as fronto-orbitonasal fracture (FONF) under the influenceofexternal forces.Material and methods: A commercially available model of the skull was used for the study. The loads were applied to the frontal bone of the skull in order to locate dangerous stresses that are typical for FONF.Results: As the area of force application changed,significant differences in the values,quality and the area of stress distribution were revealed.Conclusion: Extending the area of force application changes the value and the area of stresses typical for FONF that occur at the base of the anterior cranial fossa
