The Finite Element Method (FEM) is a numerical method for modeling static and dynamic simulations displaying a high power analysis.
The method gives approximate numerical solutions to equations that predict the response of physical systems subjected to external influences. The clinical extrapolation from mathematical models can provide a detailed description of the layout and relationship of forces and stresses without the variability of nature.
Aim: This paper applies FEM to determine the mechanism of orofacial trauma in dummies subjected to frontal impacts with vehicles under various conditions.

We built a virtual model to evaluate automotive restraint systems (seat belt and airbag of occupant). The areas of interest were defined as follows.
The nasal region, two regions of right and left zygoma, and the mandible and maxilla divided into quadrants.
The objective is to evaluate the loads, acceleration, and the severity of injuries under different conditions and quantification of these values.
The results of this interesting study are presented with some impressive videos.
Conflict of interest: None declared.
