There are several methods of dental implant bone grafting; block bone grafting entails removing bone from another part of the patient’s body. Autogenous bone for a dental implant bone grafting procedure is usually harvested from a patient’s hip or chin, implanted in t he area where the tooth is being replaced, and allowed to heal and grow new bone for at least three, and as long as six months. Any bone taken from areas outside the patient’s mouth will have to be removed in a hospital by an orthopedic surgeon, and transferred to the dentist.
Allograft bone used in dental implant bone grafting is taken from cadavers and under the very close supervision of bone banks. This type of bone harvesting has been going on for years and has supplied bone for thousands of medical and dental procedures with no instances of transmitted disease.
Animal bone used in dental implant bone grafting is known as xenograft, which is the term used for any trans-species transplanting. Both allograft and xenograft dental implant bone are foreign substances to a patient’s body and, very infrequently will trigger a rejection.
