We developed a project to assist a team of maxillofacial surgeons by 3D reconstructing a diseased mandible bone of an elderly patient. After processing the DICOM images, we obtained a highly detailed anatomical model with the sole purpose of doing a 3D print of it and use it as a physical model for preoperative planning and shaping the reinforcing titanium plate. The model was printed using our FDM (Fused Deposition Modeling) technology in 0.007″ layer resolution.
