Summary
Rapid prototyping techniques are widely used in different medical areas, being useful for preoperative management and saving clinical time in various surgical procedures. The purpose of this work was the manufacture of a biomodel by the means of 3D printing using the fused deposition modeling technique, proving that it was a faithful replica of a dissected human jaw. A 3D model was generated from the volumetric acquisition with CBCT of a mandible with craniometric reference markers and was printed using fused deposition modeling technique. The comparison of both jaws was made with the measurement of the distances between the different craniometric points, in a homologous way. There was no statistical difference for the results of the comparison between both structures, obtaining an average dimensional error of 0.16 ± 0.11. The manufactured model corresponds to a reliable replica of the original jaw, allowing validation of the technique for later clinical purposes.
KEY WORDS: mandible, oral surgery, cone-beam computed tomography, anatomic models.
