In recent years, preoperative surgical simulations with three-dimensional (3-D) computed tomography (CT) data of a patient's skull have been utilized in orthognathic surgery , . In surgical simulations, the cutting and repositioning of bone pieces is quantitatively planned to evaluate in advance the effectiveness of the operation. In addition, the remarkable progress of soft tissue simulation and artificial intelligence also provides for a forecast of the patients’ profile after their surgery , . However, during an operation, the methods by which surgeons can conduct the planned treatment are limited, and the surgeons’ skill and experience directly contribute to the completeness and effectiveness of a presurgical plan . During standard orthognathic surgery, it is still very difficult for the surgeon to successfully finish the preoperative plan, because procedures such as incisions of soft tissue, cutting and drilling bones, and suturing are performed within the oral cavity from an aesthetic point of view. Such a limited working space requires high surgical skills when operating the osteotomy device, which is a great challenge both mentally and physically for the surgeon. Therefore, robotic technologies have recently been introduced into orthognathic surgery to support the surgeon –. In these studies, it is reported that robotic surgery offers great advantages in terms of positioning accuracy. Despite these advantages, robotic surgery is not yet widely applied to orthognathic surgery in practical clinical use.
