After adjustment of the osteotomy trajectory, the plateau of a 4.5x14 mm bone-level implant is placed at the mesial crest level (Fig.6 *); the most coronal microthreads of the implant are not covered by the native bone mesiodistally (arrowheads), 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.
