In recent years, stress analysis of dental structures has been a topic of interest with an objective of determining stresses in the dental structures and improvement of the mechanical strength of these structures. The study of orthodontic biomechanics requires the understanding of nature of stress and strain induced by orthodontic forces. FEM is an engineering method of calculating stresses and strains in all materials including living tissues. The finite element analysis provides the orthodontist with quantitative data that can extend the understanding of physiologic reactions that occur within the dentoalveolar complex. Such a structural analysis allows the determination of stress resulting from external force, pressure, thermal change, and other factors. The scope of the review covers various steps of finite element analysis, its applications in context to orthodontics and general dentistry.
