The osteotomy is finished with combination of osteotomes and reamers.  Fig.6 shows that a 5x14 mm tap is inserted at the site of #13 and that the sinus floor is lifted.  In fact the sinus membrane is partially torn at the osteotomy, which is repaired by insertion of Colla-form Dressing (Impladent), followed by autogenous bone (harvested from reamers at the site of #12) mixed with Osteogen  (Impladent).   Then an implant is placed.
