Virtual Surgical Planning in Mandibular Segmental Resection

Before surgery, the patient's lower jawbone tumor is replicated using a 3D-printed original model without adjustments. Then, the model undergoes manual modification by drilling and adjusting the jawbone model at the tumor site using drills and manual instruments. Subsequently, the reconstructed model is formed preoperatively based on this modified model. During surgery, the patient isn't guided by surgical guides, and the incision lines are relatively dependent on the surgeon. Additionally, while fixing the remaining bone after the sectioning, the surgeon uses pre-bent fixation plates made earlier to assist in stabilizing the bone.

Before surgery, the patient's lower jawbone is 3D-printed, designed to remove the tumor mass, and create a suitable margin for reconstructive plate bending. Subsequently, the reconstruction plate is pre-bent preoperatively based on this model. During surgery, the patient is guided by specific surgical guiding tools: cutting guides. Additionally, while fixing the remaining bone after sectioning, the surgeon is assisted by bone fixation instruments to stabilize the alignment of the two bone fragments according to anatomical structure and then proceeds to use pre-bent reconstruction plates to secure the bone.
