“…With these advancements, computer-assisted design (CAD) and computer-aided manufacturing techniques have now become essential for oral and maxillofacial surgeons [ 2 , 4 ]. In addition, the usefulness of in-house manufacturing, in which three-dimensional (3D) printing is performed within its own facility, has been demonstrated in recent years [ 5 - 7 ].…”

In recent years, intraoperative surgical guides have been widely used in oral and maxillofacial surgery to navigate the resection sites. However, most of them are designed for segmental mandibulectomy and determine only the anterior-posterior cutting sites. In the case of marginal mandibulectomy, the depth and angle of the resection need to be considered in addition to the anterior-posterior cutting site. This report describes a method for creating a translucent mandible model with a colored tumor that enables visualization of the tumor depth and a surgical guide for marginal mandibulectomy with a planned resection angle. If accurate surgical planning and intraoperative navigation are established using this method, personalized surgery is realized according to tumor features and hence avoids over- or under-resection.
