[Reconstruction [correction to Reconstrction] of mandibular bone defects by using the techniques [correction to teachniques] of the reverse engineering and rapid prototyping].
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 procedures 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 had been successfully put into clinical use for maxillofacial surgery in 2 patients and got a satisfactory result.


CONCLUSIONS
Reverse engineering combining with rapid prototyping could accomplish the design and manufacture of implant for the restoration of mandibular bone defects.
