Title
Evaluation Of Stress Distribution In Mandible During Orthodontic And Orthopaedic Force Application Using Finite Element Method
Abstract
AIM: The aim of this study was to evaluate the effects of the orthopedic and orthodontic forceson the mandible using 3-dimensional (3D) finite element stress analysis. The various forces that are taken into consideration are 3 loads of each type: Activator, Chincup, the combination of activator and headgear and the orthodontic forces.METHOD: A 3D finite element model of the mandible was constructed using a CT scan of a patient. The model consisted of 514,973 elements and 101,058 nodes. The stress regions and deformations were studied under 3 different loads for each type of force application.RESULTS: The principle stresses and Von mises stress were seen at the neck of the condyle and the displacement is seen at the chin in all the types of force applications studied.CONCLUSION AND SUMMARY: In all the cases studied, the results show that the highest values of principle stress, Von Mises stresses are maximum at the neck of the condyle. The highest values for deformation are at the chin.
