Mandibular reconstruction using nonvascularized autogenous bone grafting

This paper will discuss reconstruction of the mandible with autogenous nonvascularized bone grafting. New developments in this area will be investigated by reviewing the most recent literature on this topic as compared with other techniques currently employed. With the advances of vascularized free flap reconstruction it is important to investigate the indication for nonvascularized techniques.

Replacement of a portion of the mandibular bone is a common procedure for patients undergoing ablative cancer surgery or for infection as well as temporomandibular joint replacement secondary to disease or trauma. The subject of mandibular reconstruction has seen great advances in recent years with the advent of vascularized free tissue transfer. Other newer areas of mandibular replacement include tissue engineering and distraction osteogenesis. Traditional nonvascularized autogenous bone graft replacement can still play a vital role in rehabilitating these patients.

Although vascularized free flap reconstruction of mandibular defects has become the more common method of treating the postablative cancer surgery patient, there remain indications for nonvascularized reconstruction of mandibular defects as well as other techniques.
