One of the serious consequences of single or multiple tooth extraction is the bone resorption that follows, which may create aesthetic problems and compromise future implant placement. Ridge preservation procedures typically use a combination of a scaffold and a membrane. Scaffolds most commonly used are bone grafts; autogenous, allografts, xenografts, and alloplasts. Among these bone grafts, allograft materials such as Demineralized Freeze Dried Bone Allograft (DFDBA) and Freeze Dried Bone Allograft (FDBA) are frequently used in site preservation procedures.
