Finite Element Method in Orthognatic Surgery

Abstract

The paper addresses the potential applications of the finite element method in orthognatic surgery. The finite element method has become a valuable research tool in dentistry due to its versatility, capacity to simulate complex geometry, and quick results. It is used for stress and strain analysis in complex mechanical systems and allows for the mathematical transformation and analysis of mechanical properties of geometric objects. The advantages of the finite element method in orthognatic surgery include reduced need for long-term animal tests and unethical tests in humans, noninvasiveness, imaging of superimposed structures, simplified analysis of the materials and geometry of orofacial structures, accurate determination of the direction and magnitude of the applied force, theoretical measurements of stress points, constant physical properties of assessed materials, high repeatability of tests, as well as static and dynamic analysis. The disadvantages of the method include the effect of the equipment used on the quality and details of findings, the need for extensive knowledge of materials science, the risk of errors in input data, statistics, and interpretation of findings, the need for advanced computer skills, and the inability to predict changes in assessed structures. Overall, the finite element method has proven effective in addressing biomedical issues in dentistry and orthognatic surgery.
