Technological advances in three-dimensional (3D) imaging, computer-assisted surgical planning and simulation in the field of medicine are now regularly being used for analysis of craniofacial structures. It also gained ingress in prediction of surgical outcomes in orthognathic surgery. A variety of patient-specific surgical guides and devices have been designed and manufactured using 3D printing technology, which rapidly gained widespread popularity to improve the outcomes. The article presents an overview of 3D printing technology and its applications in orthognathic surgery with emphasis on treatment feasibility and patient outcome.
