The usage of a customized reconstruction plate is an effective method for the reconstruction of mandibular continuity defects. This project aimed to investigate the biomechanical behaviour of the customized reconstruction plate by finite element method. In designing customized plates, it is important to assess potential biomechanical responses. This is substantially depending on the size and geometry of the defect. This project checks out to do Finite Element Analysis (FEA) on the conventional type mandibular plate and screws which are fixed to join fracture occurring at the symphysis area of the mandibular bone subjected to uniform loading.
The tutorial video:
The Computer Tomography (CT) scanned images of a patient are collected in Digital Imaging and Communications in Medicine (DICOM) format. These images are then imported into image processing software MIMICS to develop the 3D surface model of the mandible. Next, we import it into the 3-Matic software to modify the surface model and then finally save it ".STL" file format. The saved ".STL" file format is imported into Solidworks software to develop a 3D CAD model consisting of an assembly of the mandible, conventional type of miniplate, and screws. Next Step, The 3D CAD model of the assembled file was imported into Abaqus and analyzed by applying uniformly distributed load on the molar teeth area of the mandible. The whole process is simplified by using the STL files in Abaqus.
The input given for Finite Element Analysis was the material properties of the cortical and cancellous bone of the mandible and for implant and screws the material properties of titanium alloy. In the contact module, suitable contact conditions with a coefficient of friction of 0.3 were defined for the model. For the mesh, hexahedral and triangular elements were assigned to the components depending on the geometry of the part.
Here, one case was considered and analyzed under structural loading conditions by applying force on a molar tooth. In this simulation, an explicit step is used. At the end of this video, you can see the exact location of von Mises stress in the mandibular plate.
The recorded video is about 5 minutes and helps you to learn how to use Abaqus for this purpose.
You can download the Abaqus CAE file which includes the parts and the assembly.
