The purpose of this article is to find alternative donor site for oral and maxillofacial bone defect. Autogenous cancellous bone is gold standard of bone graft materials. Anterior iliac crest is first choice to get autugenous cancellous bone. But it has some problems. For example, gate problem, large scar formation, and limitation of ambulation, etc. Bone harvesting from proximal tibia is simple and non-aggressive method to get autogenous cancellous bone. We had three cases of tibial bone graft, and we can get 8-17cc of cancellous bone. Patients can work immediate after surgery by their own feet, and had minimal discomfort and gate disturbance. If surgeon want sufficient amount of biologically highly valuable cancellous bone, proximal tibia could be one of the excellent donor site.
