After removal of granulation tissue (Fig.4), allograft in sticky bone form is packed (Fig.5). To prevent periimplantitis in similar situation, the immediate implant should be placed deep (not necessarily long, 18 mm) and narrower (3.5 mm instead of 3.8 mm). The defective buccal plate should be repaired with sticky bone and collagen membrane with incision if necessary.
