The Role of Computer-Assisted Design and Modeling in an Edentulous Mandibular Malunion Reconstruction

Mandibular trauma is a common problem encountered by the craniofacial surgeon. Fractures in the edentulous mandible represent only 3% of these injuries, and optimal management is controversial. This problem is further compounded by malunion and malocclusion when fracture lines heal in incorrect positions. Even with recent advances in imaging and hardware systems, they remain difficult problems that often require multiple operations to obtain satisfactory results. We present a 69-year-old man with an edentulous mandibular fracture and concomitant malocclusion after a series of unsuccessful operations. By using computer-assisted design and manufacturing technology, we were able to plan osteotomies for correct anatomic positioning, which restored dental occlusion and facial aesthetics. A follow-up at 6 months postoperatively revealed a stable and anatomic reconstruction.
