Allograft

An allograft is a type of graft which utilizes tissue from genetically dissimilar members of the same species. Four types of allograft exist: frozen, freeze-dried bone allograft (FDBA), demineralized freeze-dried bone allograft (DFDBA), and solvent-dehydrated mineralized allograft. Allograft bone is processed and prepared by tissue banks. In dentistry, allografts such as bone grafts are used to build up the bone where an implant or prosthesis will be placed. Some patients have insufficient bone due to disease or other health concerns and therefore do not have the proper foundation for an implant. A bone allograft ensures a stable structure for the placement and success of dental prosthetics. Bone used in allograft procedures generally comes from human cadavers that have willingly donated their bodies for such purposes. Due to its source, allograft material is strictly regulated by both the American Association of Tissue Banks and the US Food and Drug Administration
