Basic Concepts of Finite Element Analysis and its Applications in Dentistry: An Overview

Mohammed SD and Desai H

In attempt to improve mechanical properties of various dental structures, analysis of stress and strain of the same under various loading circumstances has become a integral part of research in recent era. As we all know, oral cavity consists of various complex structures with a very limited accessibility. Due to this, most biomechanical research of the oral environment has been performed in vitro. Finite Element Analysis (FEA) is a modern tool for numerical stress analysis, with an advantage of being applicable to solids of irregular geometry that contain heterogeneous material properties. The history of Finite Element Analysis (FEA) dates back to 1943 when R. Courant first developed this technique. This article provides a review of the achievements and advancements in dental technology brought about by all powerful finite element method of analysis. The scope of the review covers various steps of finite element analysis, its applications in context to orthodontics, restorative dentistry and endodontics as well as to the field of implantology. Advantages and limitations are discussed in some detail which helps identify the gaps in research as well as future research direction.
