Topology optimization of mandible fracture plate

One of the most often fractured facial bones is mandible. It is also the most common fractured among the patient with multiple injuries. A mandible fracture plate is designed based on topology optimization to overcome the problem caused by standardized mandible fracture plate. The mandible fracture plate is design in Autodesk Inventor and it is analysed in shape generator to remove excessive material. The plate is simulated in ANSYS workbench in axial and multiple load. The plate is designed in three thickness that are 1.0mm, 1.5mm and 2.0mm. Each thickness is simulated using titanium alloy, stainless steel and polylactic acid (PLA). The mandible fracture plate is fabricated using Fused Filament Fabrication (FFF). By using topology optimization, the volume of mandible plate can be reduced up to 50%.
