Types of Bone Grafts
AutograftAn autograft is considered the gold standard of bone grafting. This type of graft involves taking tissue from one area and transplanting it to another on the same person. For bone grafting, this means taking bone mass from one area of your body, typically the hip or tibia, and transplanting it to the weakened area of your jaw. The bone may also be taken from another area of the mouth, including the back of the jaw or the chin.
Autografts typically have the highest success rate. This is because the bone tissue harvested is considered living, and the cells contained within the tissue are still intact. Another major benefit of this type of graft is that because we use your bone tissue, there is no risk of immune reaction or disease transmission. However, the biggest drawback of this type of graft is that an additional surgical site is required to harvest the necessary bone mass.
AllograftAn allograft is a graft that is performed between two individuals of the same species, in this case, humans, but who do not share an identical genetic makeup. The bone is generally taken from a cadaver. Before use, the bone is heavily screened and processed to reduce the risk of an immune reaction or disease transmission. These types of treatments include irradiation, freeze-drying, acid washing, or other chemical treatments. The biggest advantage of this type of grafting is that you do not need the additional surgical site to harvest bone mass.
XenograftA xenograft is a tissue graft that is done between two different species. For example, using bone material from a cow or pig in the jaw of a human. The harvested bone is processed at very high temperatures to reduce the risk of immune responses or the transmission of diseases. Xenografts are often chosen because larger amounts of bone with a specific microstructure can be harvested. Again, much like an allograft, a xenograft does not require the additional surgical site for harvesting bone tissue.
AlloplastAn alloplast is a type of graft that involves any type of synthetic graft material not derived from human or animal origin. For bone grafting in oral implantology, this often involves the use of hydroxyapatite. Other synthetic bone grafting materials involve demineralized bone matrix and bone morphogenic proteins.
A bone graft can greatly help to increase the success of your dental implants by restoring strength and shape to your jaw. A thorough oral exam is needed to determine your specific needs and to determine the best type of bone graft for you.
