Development of the customised implant system using CAD/CAM/CAE tools

In this paper, the 3-dimensional (3D) modelling of jaw and other artificial structures and most realistic simulation models are developed and studied. Optical scanning, computer aided design (CAD) and computer aided analysis (CAE) programs are integrated with each other are used. The DICOM (Siemens medical image format) files that are obtained by scanning computer tomography (CT) images of jawbone are transformed into two different point cloud format as cortical and cancellous bone layers. Obtained point clouds are firstly converted to the solid model format and then combined in SolidWorks. In this way, specific jaw model of the patient is obtained. Finally, the appropriate implant, abutment and crown bridge for the jawbone is modelled. Created 3D solid models are assembled in SolidWorks and were made suitable for the finite element analysis (FEA). Structural analysis of created 3D solid model was carried out in ANSYS with the finite element method, locations and amounts of stresses and displacements were determined by examining the stress distributions. Thus, the most appropriate geometry and material of implant, abutment and crown bridge that will be used in the implant treatment for the patient are assigned and a basic structure is formed that all types of improvements can be applied. © 2016, © 2016 Informa UK Limited, trading as Taylor & Francis Group.MMF2010BAP112This study is supported by Çukurova University Research Fund [MMF2010BAP112]
