Nowadays, virtual treatment planning allows clinicians to create detailed, patient-specific workflows through digital simulations. This improves the accuracy of treatment plans and leads to efficient, and patient-centric care. In dentistry, Computer-Aided Design and Manufacturing (CAD/CAM) enables the virtual design and fabrication of all kinds of oral devices. Finite Element Analysis FEA is increasingly used as a virtual simulation to assess the mechanical behavior of designed oral structures and devices. In the present paper, a Finite Element Analysis (FEA) simulation is used to understand orthodontic loading effects on tooth movement and adjacent structures. Cranio-facial imaging data (Dicom) was used by 3D modeling, to generate a virtual simulation model. FE analysis was conducted on a partial dento-alveolar model. All materials (teeth, PDL, and alveolar bone) were considered to have isotropic linear elastic properties. The preliminary findings of our study, are conclusive for the accuracy of the model. The tooth movements concord with the applied force. We observed a corono-distal version, similar to the movements encountered in clinical orthodontic practice. Undesirable Tooth movements could also be identified as disto-palatal rotation of the tooth, leading to activation adjustments by the operator. The value of Finite Element Analysis (FEA) in virtual treatment simulation is once again confirmed through a model of orthodontic treatment. Clinicians may be able to develop more effective and mechanically sound treatments with the use of numerical simulation. Further investigations will attempt to analyze bone remodeling, and root deformations in order to study the stresses suffered by the root and its apex during tooth movements.
