Fig. 5. Orthognathic surgery can benefit from 3D printing.

Orthognathic surgery can benefit from three-dimensional (3D) printing technology. (A) Various anatomic landmarks on the 3D printed model can be found preoperatively, which enable the surgeon to perform the satisfactory surgical process. In addition, this is very useful for the consultation with patients and the presurgical simulational surgery. (B) In case of severe asymmetry, the rapid prototype model can provide 3 dimensional images for the surgeons.
