With the recent advances in three-dimensional (3D) technology, orthognathic surgery has steadily evolved, gradually performing more sophisticated surgery and expanding its scope of application. The objective of this study is to summarize the current evidence of the application of 3D technology in the field of orthognathic surgery, with the hope of providing helpful information for practitioners who are interested in orthognathic surgery.

Peer-reviewed articles published in English were retrieved from literature through an extensive search performed in PubMed/MEDLINE. The application of 3D technology in orthognathic surgery can be summarized from the aspects of preoperative diagnosis, surgical planning, surgical procedure and postoperative evaluation. There is evidence that supports the use of 3D technology, including cone beam computed tomography (CBCT), 3D imaging devices, 3D printing technology, navigation, computer-aided design and computer-aided manufacturing (CAD/CAM), can help improving orthognathic surgery and achieving promising outcomes.

Even though there may be an added cost, the application of 3D technology has provided decreased operative time and hospital length of stay, which is positive for both practitioners and patients. With precision and minimal invasiveness, 3D technology is considered to be an effective method in exploring more scientific and reasonable programs and procedures of orthognathic surgery.
