Dental Implant Distractor Combined With Free Fibular Flap: A New Design for Simultaneous Functional Mandibular Reconstruction

PurposeThe purpose of the present study was to present a new method that combines the use of the fibular flap and a custom-made vertical distractor/dental implant device into 1 surgical procedure for simultaneous functional mandibular reconstruction.Patients and MethodsThe present retrospective case series included 10 patients who were treated using the fibular flap and dental implant distractor (DID) in a single-stage procedure. These 10 patients were treated within a 3-year period (from 2005 to 2007).ResultsOf the 10 patients included in the study, 5 were males and 5 were females. The mean age of the sample was 33.8 years (range 17 to 48). The cumulative survival rate of the fibular flaps was 100%. The mean vertical bone height attained with the DID device was 11.4 mm. The mean period from the first operation to the start of dental implant loading was 6.3 months. The cumulative survival rate of the dental implants was 93.75%.ConclusionsThe use of the DID in the fibular flap for mandibular reconstruction is advantageous because it combines vertical distraction osteogenesis of the fibular flap and dental implantation into a single procedure. Implants placed in the reconstructed areas were found to integrate normally, with survival rates comparable to those with 2-stage operations. As such, this novel DID technique can be used for single-stage reconstruction and rehabilitation of segmental mandibular defects in selected patients.
