Since there is no corresponding tap available, a 8x17 mm cylindrical implant is used to form osteotomy slowly and steadily and finish placement with insertion torque between 45 and 50 Ncm (Fig.4).  Radiologically the apex of the implant is engaged to the bottom of the socket, whereas clinically the implant contacts the buccal and lingual plates.  There is space mesially and distally for bone graft.

X-ray 2 months postop shows bone graft (Fig.6 *) deposited near implant threads (>).

The definitive restoration is delivered 3 months postop.  Fig.7 is taken 1 month post cementation; the crown margin is supragingival (<: gingival margin), which is easy for cement removal.

Seven months post cementation (10 months postop), the bone graft remains distal to the implant (Fig.8 *), while bone density mesial to the implant continues to increase (<). There is no bone loss 2 years 7 months post cementation (Fig.10,11).

Bone density around the implant increases as time passes (Fig.4,6,7,8,10,11).
