Demineralized allograft (.0125-.085) is placed for sinus lift (Fig.4 *) prior to placement of 4.5x11 mm implant with ~ 30 Ncm.  A 4.5x4(2) mm pair abutment is to be placed for an immediate provisional to hold mineralized allograft in the remaining socket gaps (arrowheads, .5-1.5 mm).

The implant appears to have osteointegrated 5 months postop (Fig.6).   The abutment is incompletely seated.
