The most coronal microthreads of the implant are not covered by the native bone mesiodistally, but by bone graft (Fig.7 *, mineralized cortical and cancellous allograft and Osteogen).  The implant plateau is 1-2 mm apical to the CEJ of the neighboring tooth (Fig.7 >).  A 5.8x4(3) mm abutment (A) is placed immediately for an immediate provisional.  The abutment also helps keep the graft in place.  The graft is also placed buccally to repair the buccal plate defect.

The patient returns for final restoration 3 months 11 days postop.  The density of bone graft appears to be reduced (Fig.8, as compared to Fig.7).  There is dense bone formation at the coronal end of the implant 2 years 5 months post cementation (Fig.13 *) with the normal soft tissue.
