Finite Element Analysis of Human Mandible and Development of Implant by Additive Manufacturing
Abstract: A computational study using DICOM (Digital Imaging and Communications in Medicine) information to create a 3D model of the jaw. The files were loaded into the Slicer 4D software, which was used to build the model by thresholding each slice of the file. The model was then imported as an STL file using the Siemens UG-NX 11.0 programme for convergent modelling, which transformed the facets into a single solid model. The model was imported into ANSYS-Workbench 2019R3 software with IGES file extension, with two different boundary conditions such as fixed supports and hinged supports on the condylar region of the jaw using Bone, Titanium (Ti6Al4V), PMMA, and PEEK as various materials, and Material optimization analysis was performed on the jaw. The behaviour of the implant was studied when the jaw was subjected to a mastication condition of 7.2MPa as the load as the maximum bite force and 0.5MPa as static pressure as the maximum pressure on the jaw, Suggesting the appropriate material for the implant from the analysis by comparing the results with the material properties of bone and the properties of different materials mentioned above, and 3D model is fabricated using STL file in Cura software and Ultimaker 3D as a machining platform.
