An immediate provisional is laid outside the buccal gingiva to prevent loss of bone graft, but a large gap develops underneath the provisional buccally with loss of bone graft, noted 1 month postop. The buccal gingiva is also found to perforate after removal of the provisional. These are related to the extensive preop buccal plate loss. The buccal threads are exposed. After induction of hemorrhage from the surrounding healthy granulation tissue, Osteogen plug is placed in the buccal gap, covered by periodontal dressing, which stays 9 days postop (Fig.6).
