Abstract
Additive Manufacturing of ahuman mandible physical model is developedfrom thepatient having missing teeth at first molar position usingFDM (Fused Deposition Modelling) technique. These physical models are helpful for the surgeons to perform pre-operative procedure to improve the success rates of the surgery. Genesis AKTIV implant is Modelled using CATIA V5 software by considering DICOM Datain NNT viewer software. Finite element analysis is performed on implant with occlusal force and torque. For this initially DICOM data of mandible is extracted from CT Scan and converted to STL format using InVesalius medical modelling software. Modelling of fixture, abutment and screw are developed with IMPLANT GENESIS AKTIV implant standards using CAD software. Depending on the NNT Viewer results suitable parameters are chosen to develop fixture. STL file attained from medical modelling software is further processed and converted to STEP format for performing analysis. Analysis is performed to check deformation and vonmises stress using ANSYS software. Finite element analysis results shown that the von mises stresses does not surpass the yield strength and all the stresses generated are permissible to the mandible.
