Abstract: Mandibular Reconstruction Using Cost-Effective Three-Dimensional Printing

M oday, O cber 9, 2017 These models are rendered and imported into BlenderTM (Amsterdam, The Netherlands). They are then inverted along the vertical axis to create a working template of the contralateral ear. The depths of the scapha, triangular fossa and cymba are deepened to accentuate contours. Additional relief is added to the helical root for further definition. The final template is digitally separated to create the requisite components for the Nagata technique: helix; antihelical fold with the superior and inferior crus; tragus; and base frame. The helix is digitally straightened to optimize modeling. Finally, the complete auricular model and its components are individually 3D-printed (Builder Premium 3D Printer, Noordwijkerhout, The Netherlands) using polylactic-acid filament and sterilized according to manufacture’s specifications (121°C for 1 hour and 30 minute dry cycle).
