Head and Neck: Lower Jaw Reconstruction
Buenos Aires, Argentina
✔ Design of the surgical plan
✔ Practice of the operation
✔ Moulding of the osteosynthesis plate
✔ Specific positioning and adjustment of the fibula to the plate
A 56-year-old man with osteosarcoma of the lower jaw.
The patient underwent two surgeries, the first of which involved tumour resection and placement of a temporary plate. In the second, reconstruction of the mandible was performed. For this purpose, a biomodel was requested.

Surgical plan and results in operating room
To reconstruct the inferior maxilla, the fibula is used to be placed on a titanium osteosynthesis plate.
The 3D model was used for the pre-moulding of the definitive titanium plate prior to surgery and the appropriate positioning of the fibula on the plate, taking into account the patient's anatomy.
The model underwent a sterilisation process that did not alter its physico-chemical characteristics in order to bring it into the operating theatre and bring it into contact with the biological material.
