Applications of finite element analysis in dentistry: A review

Aim: This review highlights the fundamentals of finite element analysis (FEA) and its applications in various fields in dentistry. FEA is a computer-based numerical technique for calculating the strength and behavior of structures. It can be used to calculate deflection, stress, vibration, buckling behavior, and many other phenomena. Established knowledge regarding applications and limitations of FEA which are published are discussed in detail which can aid in identifying the caveats in research. Materials and Methods: Various literature sources were selected through a search of PubMed, Scopus, Web of Sciences, Google Scholar, and other electronic databases and were subjected to intense scrutiny under the search title "Finite Element Analysis in Dentistry." We identified and reviewed most relevant and recent work mostly indexed in Scopus and PubMed. Results: A simple search on Google Scholar resulted in 144,000 scientific articles and 17,200 articles since 2017. Most of the articles were related to the application of FEA in implant dentistry. Forty-four such articles were included in this review. Conclusion: Based on our literature search, we came to the conclusion that applications of Finite Element Analysis in Dentistry are myriad and this technology is constantly upgrading. This review will provide an update on the current state of scientific knowledge in this field that encompasses all areas of dentistry. We also emphasise the need for further research in this area.
