Several techniques have been suggested for the reconstruction of a severely atrophic mandible before implant placement. Autogenous bone graft with titanium mesh has become an acceptable treatment modality for partially edentulous regions.
This report describes autogenous bone graft with titanium mesh for reconstructing the mandible and investigates its stability for long-term success.
A 50-year-old male was diagnosed with bone resorption in the right side of the mandible. Radiographic examinations were carried out on the bone resorption area and we planned to reconstruct the mandible using autogenous bone. Tibial bone was used as an alternative source for obtaining sufficient bone. As a result, 6 g of autogenous bone, including cancellous bone and cortical bone, were collected. An autogenous bone graft with titanium mesh was used to reconstruct the mandible. Implant placement was performed in the mandible after 3 months. The patient was clinically and radiographically examined 3 months after the bone graft and thereafter annually for 5 years. Resorption of autogenous bone graft reached 16% after 5 years. Long-term stability of the bone morphology is an important factor for implant success.
