Biomechanics refers to the study of structure and function of biological systems, using methods obtained from mechanics, which is concerned with the effects that forces have on the motion of bodies. Recently, there has been a development of implementation of various virtual studies in the field of biomechanics. One such remarkable development is the technology of finite element analysis (FEA). Through this technology, complex mechanical systems in human body, which otherwise are difficult to understand in vivo, could be studied using mathematical conversion of the geometrical model in question. This has its implications in the field of trauma surgery, especially oral and maxillofacial surgery, reconstructive surgery and implantology. The available literature indicates FEA to be an important instrument in understanding and reconstructing complex human mechanical systems. Keywords: Finite Element Analysis (Fea); Maxillofacial Surgery; Traumatology; Reconstructive Surgery; Implantology.
