Abstract

Virtual surgical planning and three-dimensional (3D) printing have broadened the horizons of oral and maxillofacial surgery, including orthognathic surgery. 3D-printed personalized surgical guide and patient-specific implant (PSI) not only serve to guide accurate osteotomies and as a good fitting of osteosynthesis plate, but more importantly define a revolutionary waferless approach concept that is totally different from the conventional wafer-guided jaw fixation technique. This review discusses the limitations of the conventional orthognathic approach, and how PSI may overcome these limitations, improve accuracy, and bring additional benefits in the execution of orthognathic surgery.
