With more allograft for sinus lift, a 5x9 mm implant is inserted with >35 Ncm (Fig.3).  The implant appears osteointegrated with sinus lift 2.5 months postop (Fig.5 *).  Half month later, a pair abutment (5.5x4(4) mm; 25 Ncm) is placed at #15.  When the patient returns 7 months postop, BWs are taken to confirm that the abutment at #15 is fully seated, whereas that at #14 is not (Fig.6 (>: gap)).
