The Finite Element Method (FEM) is an advanced computational tool widely used in orthodontics to analyze stress distribution, tooth movement, and biomechanical behavior of craniofacial structures under various orthodontic forces. FEM enables the creation of detailed three-dimensional models of teeth, periodontal ligaments, alveolar bone, and orthodontic appliances, allowing researchers and clinicians to simulate clinical conditions with high precision. This method helps in understanding the effects of orthodontic forces on biological tissues, optimizing appliance design, and predicting treatment outcomes while minimizing adverse effects such as root resorption and bone loss. FEM has significant applications in the evaluation of brackets, wires, aligners, mini-implants, and orthognathic procedures. The integration of imaging technologies such as cone-beam computed tomography (CBCT) and computer-aided design has further enhanced the accuracy and reliability of FEM simulations. Despite limitations related to model assumptions, material properties, and computational complexity, FEM remains a valuable research and diagnostic tool in modern orthodontics. Its application contributes to evidence-based treatment planning, improved biomechanics, and the development of more efficient and patient-specific orthodontic therapies.
