Analysis of Stresses in Mandible and Skull under Angular Impact

Finite element analysis has gained a significant attention in the field of biomechanics. The versatility of finite element analysis is the major reason behind its implementation and adoption has made the study of biomechanics much easier and simpler. FEA, as a tool has helped in analyzing the various organs in human body in different loading conditions. Be it Orthopedic,Maxillofacial fractures,Orthodontics, Prosthodontics, hemodynamics, it is finding its applications in all areas of biomechanics. In this paper, one such study has been carried out to understand the behavior of skull and mandible under inclined impacts. Skull is one of the highly complicated structures made up of bones in the human body.A lot of research is being carried out throughout the world for studying the skull structure in multidisciplinary level. Research is also being carried out in treatments by effectively using FEA, developing new methodologies and materials for treatment in the field. Here, the model of the skull along with mandible is constructed using the CT scan data using which finite element model is created and impact analysis has been carried out to find out the stresses, strains and energy absorption of the skull material. Apart from the analysis, attempt has been made in this paper to suggest the optimum locations for placing implants to optimize treatment in trauma patients.
