Finite element analysis: New dimension in prosthodontic research

Finite element analysis method (FEA) allows detailed visualization of where structures bend or twist, and indicates the distribution of stresses and displacements. FEA software provides a wide range of simulation options for controlling the complexity of both modeling and analysis of a system. Similarly, the desired level of accuracy required and associated computational time requirements can be managed simultaneously to address most engineering applications. FEA which is an engineering method of calculating stresses and strains in all materials including living tissues has made it possible to adequately model the tooth, restorative materials and dental implants for scientific checking, and validating the clinical assumptions. The purpose of this article was to give an insight of the FEA, which has totally overshadowed other experimental analysis due to its ability to model even the most complex of geometries with is immensely flexible and adaptable nature. FEA is a computer-based numerical technique for calculating the strength and behavior of structures.
