The science of finite element analysis (FEA) is purely a mathematical way of solving complex problems in the universe. In medical field, this is an innovation in biomedical research and development, as it gives easier mathematical solution to biological problems. This article deals with the understanding of various basic material properties of bone like Young's modulus, yield strength, Bulk modulus, shear modulus, Poisson's ratio and density from a maxillofacial surgeon's perspective. Basic concepts in FEA, its application, advantages, disadvantages, and limitations in the field of maxillofacial surgery have been discussed. The importance of surgical fraternity to be in coordination with evolving technologies has been emphasized for the future of evidence based practice of oral and maxillofacial surgery.
有限元分析（FEA）科学纯粹是一种解决宇宙中复杂问题的数学方法。在医学领域，这是生物医学研发中的一项创新，因为它能为生物学问题提供更简便的数学解决方案。本文从颌面外科医生的角度探讨了对骨骼各种基本材料特性的理解，如杨氏模量、屈服强度、体积模量、剪切模量、泊松比和密度。讨论了有限元分析的基本概念、其在颌面外科领域的应用、优点、缺点和局限性。强调了外科界与不断发展的技术协调配合对于口腔颌面外科循证实践未来的重要性。
