Fig.3: The mesiodistal dimension is also limited (7 mm).  A 4.5x14 mm submerged implant is to be placed, ~2 mm from the upper border of the Inferior Alveolar Canal (yellow dashed line).  Bone graft is expected to be placed distobuccally (red circle).

If the patient agrees to have #17 extracted, #18 can be uprighted.  The implant could be placed a little distal.
