Full description
Thrirty-six patients were randomly assigned in four treatment groups: A) freeze-dried bone allograft (FDBA) covered with collagen sponge (CS), B) FDBA covered with free gingival graft (FGG), C) demineralized bovine bone mineral xenograft (DBBM) covered with FGG and D) FGG without socket grafting. Clinical measurements were performed immediately after tooth extraction and 4 months later. The related outcomes pertained to both vertical and horizontal assessment of bone loss
