Purpose: The aim of this study was to evaluate the transfer of different occlusal forces invarious skeletal malocclusions using finite element analysis (FEA).
Methods: Three representative human cone-beam computed tomography (CBCT) imagesof three skeletal malocclusions were obtained from the Department of Orthodontics, YonseiUniversity Dental Hospital, Seoul, South Korea. The CBCT scans were read into the visualizationsoftware after separating bones and muscles by uploading the CBCT images intoMimics (Materialise). Two separate three-dimensional (3D) files were exported to visualizethe solid morphology of skeletal outlines without considering the inner structures. Individualdental impressions were taken and stone models were scanned with a 3D scanner. Theseimages were integrated and occlusal motions were simulated. Displacement and Von Misesstress were measured at the nodes of the FEA models. The displacement and stress distributionwere analyzed. FEA was performed to obtain the 3D deformation of the mandiblesunder loads of 100, 150, 200, and 225 kg.
Results: The distortion in all three skeletal malocclusions was comparable. Greater forcesresulted in observing more distortion in FEA.
Conclusions: Further studies are warranted to fully evaluate the impact of skeletal malocclusionon masticatory performance using information on muscle attachment and 3D temporomandibularjoint movements.
