When a 6x9 mm IBS implant (definitive) is placed with a 6.5x5.5(4) mm abutment, they are seated too deep for provisional (Fig.8).  The implant/abutment are removed and replaced by a 6.5x11 mm one in a shallower position; after trimming the same abutment as mentioned above (Fig.9), an immediate provisional is fabricated to keep bone graft in place.  The coronal threads of the implant are covered with bone 6 months postop (Fig.10).
