The 4.5x13 mm implant inadvertently lifts the osteotomy plug and the sinus floor (Fig.9 arrowheads).  Allograft has been placed around the implant (*) prior to placement of a 4.5x4(3) mm abutment.  Due to angulation, the implant appears to have been placed deep.

There is no bone loss 4 months postop (Fig.15).
