Bone drill and grafter. Artwork of a cross-section through a bone drill and grafter that is being used to harvest bone chips from healthy bone for use in bone grafting elsewhere in the body. Bone grafting is most successful when carried out using bone from the patient's own body, known as autogenous or autologous bone. Areas of the skeleton that are used to harvest such bone grafts include the chin bone, other part of the mandible, the iliac crest (of the pelvis), the fibula, the ribs, and some parts of the skull.
