After use of 4.8 mm Magic Drill, a 5 mm tap drill does not achieve stability, whereas a 5.5x9 mm dummy implant does (Fig.4).  A 5.5x11 mm IBS implant is placed with 50 Ncm with a 6x4(4) mm abutment and bone graft (Fig.5 *).  The Inferior Alveolar Canal, unclear in the last 2 PAs (Fig.4,5), is shown in the postop panoramic X-ray (Fig.6 red dashed line).  The immediate provisional and abutment dislodge 1.5 months postop (probably due to tight vertical space); since the socket has been reduced and healed (Fig.7 ^), a healing abutment is placed.  The implant seems to osteointegrate 3 months postop (Fig.8,9).
