Fig.3: Primary stability of the 7x17 mm implant (I) appears to be achieved by engaging to the apical 3-4 mm new bone (between arrowheads, >60 Ncm).  The mesial and distal gaps are filled with allograft mixed with autogenous bone and Ostetogen (*).  Red outline: extra osteotomy for tap and implant engagement.

Bone has grown into the implant threads 5.5 months postop (Fig.6 arrowheads).
