In spite of these limitations, FEM is one of the most widely used stress analysis in dentistry today, as it is most suitable for modeling an asymmetrical structure like the tooth.
Finite Element Analysis is a method wherein one can visualize and study the stresses generated in a tooth, restoration, restoration-tooth interface etc., simultaneously for different occlusal/ incidental forces, thus generating a virtual picture of biomechanical characteristics of any restoration.
This helps us in predicting the probable success of a restoration for a given clinical situation.
Improved computers and modeling techniques render the FEM a very reliable and accurate estimation approach in biomechanical applications.
