Following deepening the osteotomy with Final Drill, the implant is placed deeper (Fig.7).  The osteotomy happens to be established in the mesial socket, since the distal socket has not completely healed (Fig.6 yellow dashed line).  Granulation tissue is removed.  Since the lingual crest is lower than the buccal one (Fig.1 B), there is lingual thread exposure after implant placement (Fig.5).  The exposed thread is covered by bone graft (autogenous bone, allograft and Osteogen, Fig.5 pink circles).  Some of the graft is apparently pushed into the distal socket (Fig.7 yellow dashed line) post GBR and suture.  As the implant is placed twice, insertion torque is <10 Ncm (although the implant is stable).  A 5x3 mm healing abutment is placed (Fig.7 H).
