Variation in the Repair of a Rib Graft used for Mandibular Reconstruction after 20 years

Mandibular reconstruction has been used in the last 100 years as a safe, effective and stable technique. Various types of grafts have been used, including the autogenous rib graft; the normal repair of this type of graft has been defined in some studies although some observations have been made indi...
