Abstract
Finite Element Analysis (FEA) helps to visualize stress, strain and displacement and biomechanics of a system. Therefore, it is of interest to assess the effects of various methods on simultaneous intrusion and retraction of maxillary anterior teeth by Three dimensional FEA. For this investigation, the 3D Computer Aided Design (CAD) models simulating Maxilla, three-piece intrusion arch, K-SIR arch and TADs were modeled in the computer finite element program. The software used for geometric modelling was Autodesk AutoCAD 2017 and Inventor 2017. The von Mises stress, principal compressive and tensile stress on PDL and alveolar bone and initial displacement of the teeth in bucco-palatal, mesio- distal and vertical direction were analyzed. Thus, the three-piece intrusion arch showed better stress distribution and controlled tooth movement compared to K-SIR arch and TADs model.
