When a 3.5x11.5 mm implant is placed at #29 in the same appointment, it appears to be supracrestal buccal.  Autogenous bone (Fig.2,3 *) is placed in the osteotomy following insertion of a healing screw (S).  Periodontal dressing is applied, but it is dislodged after dinner.  In fact there is bone coronal to the implant 4.5 months postop (Fig.4), which is confirmed during uncover procedure.
