Mandible reconstruction, using 3D-printing and virtual stl-models

Abstract

Objective – to improve functional and aesthetic results after microsurgical mandible reconstructions, using 3d-printing. This method was used at 4 patients with massive oral cavity malignant tumors. surgical tumor resection and simultaneous reconstruction, using fibula flap was performed. Yirtual three-dimensional models of the mandible and operation planning was performed using ct-scans. These models were printed in 1:1 scale with 3d-printer(fused deposition modeling – FDM) and plastic models were used during fibula shaping. The sterilization of the models was done in the formaline chamber. This method allowed to get better functional results and decrease the operation time. resection of the tumor, raising of the flap and shaping could be done simultaneously.
