Reconstruction and rehabilitation of severe mandibular atrophy using distraction osteogenesis technique: A case report

Purpose The purpose of this article is to describe a rehabilitation technique for patients with severe anterior atrophy using a combination of distraction osteogenesis and implants to support fixed or removable prostheses. Materials and Methods The surgical technique involves the use of an extraosseous distraction device followed by more than 14 mm of distraction of the mandibular symphysis. Results The patient was successfully treated by the application of 4 implants in the region of the mandibular symphysis, stabilized by an Ackerman bar, and a removable prosthesis. Conclusion Osseous distraction techniques, when possible, are preferable to block bone grafting techniques because they present considerable advantages for patients and surgeons. The combination of distraction and implant placement can rehabilitate patients with severe defects.
