| Abstract: | Objective To evaluate the feasibility of designing and fabricating customized titanium bone substitutes to restore mandibular bone defects using reverse engineering (RE) and rapid prototyping (RP) techniques. Methods Titanium tray for mandibular defects were designed and fabricated through multi-step procedure of reverse engineering and rapid prototyping, then in operation it was filled with cancellous bone and fixed. Results The bone substitutes fabricated by this method have been successfully put into clinical use for maxillofacial surgery in 4 patients and got a satisfactory result. Conclusion Reverse engineering combining with rapid prototyping could accomplish the design and manufacture of implant for the restoration of mandibular bone defects. |
