It is important to thoroughly debride and degranulate an infected (acute or chronic) extraction site prior to placement of a bone replacement graft or growth factor enhanced matrix. It is imperative to transfer the diseased site to a healthy site for future implant treatment. Teeth that present with unresolved endodontic infections, vertical root fracture, non-restorable caries associated with endodontic infection, or advanced periodontal bone loss have inflamed or infected granulation tissue surrounding or apical to the extraction socket. These lesions must be completely debrided to optimize the osseous healing and prevent intraosseous areas of inflamed tissue, which would pose a risk for short-term infection or to the long-term healing and future implant placement. Failure to thoroughly debride may lead to compromised healing and possible infection and loss of the preservation graft.
