In spite of severe bone loss and 1.86 mm remaining bone after extraction of the tooth #30, a 5x7.3 mm implant achieves insertion torque of 35 Ncm with an immediate provisional (Fig.1).  Periodontal dressing is applied for additional fixation of the bone graft (*) and Osteogen plug (P).  Although the implant is placed in the mesial socket, the coronal end of the abutment is in the middle of the edentulous area.  The implant plateau seems to be covered by the bone 4.5 months postop (Fig.5).  In fact the mesiobuccal margin of the abutment is close to the corresponding crestal bone.
