Fig.8 (intraop PA) shows a 2.5 mm reamer at the depth of 17 mm (<, at the crest level).

The osteotomy is enlarged by a series of reamers until the apical diameter (3.5 mm) of the prospective tapered implant (5x20 mm, Fig.9 I). The socket is obliterated by the tapered implant with simultaneously achieving primary stability.

With practice, the immediate implant could be shorter, smaller or both, while primary stability is still obtainable.
