Clinical case

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.

3D anatomical model

◾ Technology: SLA

◾ Material: Rigid resin

◾ Resolution: 0.01 mm

◾ Finish: Translucent

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.
