Fig.2: Prior to placement of a 7x14 mm tissue-level fixture, a piece of PRF membrane and allograft/Osteogen are pushed into the sinus without membrane perforation.   There is minimal space mesial and distal the implant.  After placement of a 6x3 mm abutment, more allograft/Osteogen is placed in the remaining socket (mainly buccopalatal).  Finally an immediate provisional is fabricated around the implant/abutment to keep the graft and collagen membrane in place.
