Then a 5x4(2) mm pair abutment is placed, followed by the third round of bone graft (Fig.3 *).  Finally an immediate provisional is fabricated to keep the graft in place.  The 2nd round of the bone graft should be apical to the implant plateau (to prevent the graft from getting into the implant well), whereas the 3rd round of it covers the remaining implant surface to reduce the possibility of future periimplantitis.
