Off axial placement of the implant (Fig.5 I) and abutment (A) is striking in the immediately postop PA (Fig.5).  Black *: septum; white *: bone graft.

In other word, the implant is placed mesially.  There would be a problem if the patient wanted to move #20 distally orthodontically.

Four months postop, the bone density in the original mesial (Fig.11 <) and distal (D) sockets increases, suggesting osteointegration.

Eight months later (1 year postop (#19)), the tooth #18 becomes symptomatic and is extracted and replaced by an implant (Fig.12).  The distal socket at #19 has disappeared, while the plateau of the implant is covered by the bone (^).
