The alveolar ridge undergoes atrophy and dimensional changes subsequent to tooth removal. Preservation of the alveolar crest can enhance the surgical site before implant placement. In the socket preservation procedure, a distinction can be made between the filling and the sealing of the socket. While the filling with substitute materials can cause disruption or delay of new bone formation, the sealing with free soft tissue grafts can lead to necrosis due to small diffusion surfaces. An autogenous composite graft is presented, which has a better healing chance by increased diffusion area. Moreover it could accelerate bone formation by osteoinduction.
