Résumé
Mandibular step osteotomy, performed for mandibular prognathism, is a difficult and time-consuming procedure. Virtual computer surgery and computer-aided design & computer-aided manufacturing have demonstrated accurate results in orthognathic surgery, though not used for mandibular step osteotomy yet. In this study, the authors report the case of a 21-year-old man with severe mandibular prognathism, with a reverse overjet of 12 mm. Step osteotomy, a modified method of body osteotomy, was planned virtually and performed using 3-dimensional (3D) printed titanium surgical guides and osteosynthesis plates, using computer-aided design & computer-aided manufacturing. At the 6-month postoperative follow-up, there were no notable complications, and normal healing was observed. Each segment was stably in place with the prefabricated plates. The proximal segments were not sagged medially or laterally. With 3D-printed surgical guides and osteosynthesis plates, intraoperative complications, such as injury to adjacent teeth and nerves, could be avoided. They also showed reasonable accuracy and helped reduce operative time and improve outcomes. Unlike surgical guides made of resin/polyamide, titanium surgical guides can be made thinner, which can reduce the extent of detachment. They also did not undergo any deterioration during the operation. Cutting guides and prefabricated plates using virtual surgical planning and 3D printing have many advantages, including reduced preoperative preparation time and operative time, reduced incidence of intraoperative complications, and improved outcomes. However, limitations still exist and further studies are required.
