| Abstract: | Objective: To evaluate the biomechanical response of the Forsus Fatigue-resistant Device (FRD) on the dentofacial complex using three-dimensional finite element analysis. Methodology: High-resolution computed tomography scans were used to create the detailed anatomical models of the maxilla, mandible, dentition, periodontal ligament, and supporting bone. Forsus FRD, McLaughlin, Bennett, and Trevisi (MBT) brackets, and 19 × 25 stainless steel archwires were modeled using CATIA and meshed using HYPERMESH. Material properties and boundary conditions were assigned, and simulations were conducted in ANSYS 14.5. Forces at 2 mm–10 mm activations were analyzed for stress and deformation patterns across skeletal and dental structures. Results: Forsus FRD showed consistent stress distribution across telescopic rods and helical springs, with peak deformation localized near the mandibular attachment. Incremental activations revealed a linear increase in force output and associated stress in the dentoalveolar structures. Maximal stress concentrations were observed at the mandibular canine brackets and the maxillary first molar tubes, correlating with the areas of highest deformation. Brackets and archwires exhibited mild-to-moderate stress under loading conditions, remaining within safe biomechanical thresholds. Conclusion: The Forsus FRD delivers controlled, continuous forces with predictable stress patterns, demonstrating its efficacy in noncompliant Class II correction. The appliance's biomechanical design minimizes fatigue risk while effectively engaging the skeletal and dental components. Finite element modeling serves as a powerful tool for visualizing and quantifying orthodontic force systems, advancing evidence-based appliance selection and treatment planning.
