Bone Expansion at Septum

A 46-year-old woman has apical periodontitis with distal crack line at #14.  There are 2 fistulae (buccal and palatal).  A gutta percha is inserted into the buccal one (Fig.1 <).  After extraction and Xylocaine gauze application in the socket, use 1.6 mm pilot drill in the septum for 7 mm, followed by Magic split and expanders for sinus lift.   Place a relatively small implant (IBS, 4.5x13 or 5x11 mm, Fig.2) in the septum or a large one (6x13 mm or 6 mm 1-piece one, Fig.3) to obliterate the whole socket.

To reduce implant micro-movement initially and increase crown retention later, choose a short abutment for immediate provisional and a longer one for final restoration if necessary.  The diameter of the abutment should be as large as possible.
