The effect of particulate cancellons bone and marrow grafts with titaniummesh on mandibular reconstruction

Objective To investigate the effect of particulate cancellous bone and marrow grafts with titanium mesh on mandibular reconstruction. Methods Nine cases of mandibular defect were selected toreceive mandibular reconstruction using particulate cancellous bone and marrow grafts with titanium mesh. Results During 3 17months follow up,all patients recovered with good mandibular shape.After operation,the bone density in the graft areas was significantly increased than before operation. Donorarea had no deformity and functional abnormality. Conclusion Mandibular reconstruction using cancellous bone and marrow grafts with titaniummesh can restablish the mandibular shape and function with little trauma and node formity of shape .It may be a good method for mandibular reconstuction
