When a 5x9 mm dummy implant is placed, it is approaching the distal socket wall.  After the last dummy implant is withdrawn, a piece of Osteogen plug is inserted and a 5.5x7 mm implant is placed with less than 20 Ncm (Fig.2).  A 6x4(2) mm abutment is inserted with intention to prevent the implant from dislodging into the sinus in case the implant becomes loose.  Vanilla Graft is used to fill the socket gap (*).  An immediate provisional is fabricated to close the large socket.
