Virtual model surgery and wafer fabrication for orthognathic surgery

Abstract

Model surgery is one of the most important steps in the preoperative workup for orthognathic surgery. In cases of complicated two-jaw surgery, manual model surgery requires many laboratory based steps that are time-consuming and may contain potential errors. Recently, a three-dimensional virtual model surgery (3D-VMS) program (3Txer version 2, Orapix, Seoul, Korea) was introduced. The purpose of this article is to present a 3D-VMS case using combined data from 3D computed tomography and 3D virtual dental casts.
