Application of digital surgery for orthognathic surgical planning

The success of orthognathic surgery depends not only on surgical techniques but also on accurate and scientific surgical design and planning. The adoption of digital surgery has created a paradigm shift in surgical planning. However, compared with traditional methods, digital surgery-assisted planning of an orthognathic operation differs fundamentally from planning using traditional methods, including the elimination of plaster dental model surgery and of the increase in splint design accuracy. This article focuses on the application of digital virtual tools for pre-operative design of orthognathic surgery to provide a virtual surgical procedure reference for surgeons who need to incorporate digital surgery into orthognathic surgery.
