With all of measures taken (including periodontal dressing), the distal bone graft (Fig.8 *) is ~ 2 mm coronal to the crestal bone (red arrow) 6 months postop. G: graft; <: septal crest. In fact the abutment is incompletely seated. The temporary crown is perforated. The gingival cuff is erythematous. A 6.8x5 mm healing abutment is installed. When the patient returns for impression, take BW to determine whether the healing abutment contacts the crestal bone.
