Highlighting the maxillofacial trauma influence on posture by FEA modeling simulation

Maxillofacial trauma lead to changes in forces and torques distribution of the stomatognathic system (masticatory system). In turn, they act on the spine through their actions and reaction leading to vicious postures. Modeling, simulation and determination of the state of stress and deformation of the spine, as an expression of postural imbalance / balance leads to obtaining benefits in guiding the functional post-traumatic rehabilitation/posture reset. This could be a possible strategy in this regard. The paper's goal is the contribution to “postural reset” of human subjects presenting trauma to the stomatognathic system and confirmation of achieving it. In order to determine the postural changes, the authors used a noninvasive diagnostic equipment for static and dynamic analysis (Diasu Pleasure Platform). Using the obtained data the modeling and simulation of the spine was made as a defining element of a human subject posture with maxillofacial trauma analyzed before the surgery and after the complete recovery. By using finite element method analysis, it was highlighted the decrease of the state of stress and deformation of the spine after full recovery of the subject in conjunction with the experimental results following the posture balancing.
