Immediately after extraction, osteotomy is initiated with drills (D1 or 2 bone), followed by insertion of a 4.5x17 mm tap (Fig.3).  A 6x17 mm implant is placed with insertion torque > 60 Ncm (Fig.4 without bone graft).  The gingiva contacts the implant, while it is difficult to approximate the mesial aspect of the socket.  Periodontal dressing is applied.
