Fig.3: CT sagittal section of the edentulous region at the site of #3. A bone level implant can be used.  The shortest implant available is 6 mm, but the smallest diameter is 5.9 mm.  As the tooth #2 is affected by periodontitis with mesial drifting (arrow), the mesiodistal edentulous space is quite narrow (6.40 mm). Placement of the large implant may be difficult.

The density of the cancellous bone as related to the implant is low.
