A 5x13 mm implant is placed superficially (Fig.5) with a trace of the previous osteotomy (yellow line) and deep space created by the mesial osteotomy (*).  Red dashed line: the superior border of the Inferior Alveolar Canal.  Apparently the pathological and iatrogenic defects are filled with allograft (Fig.6 *).  Guided surgery could have avoided the mesial osteotomy.

Bone morphology at the coronal end of the implant apparently changes 4 months postop, suggesting osteointegration (Fig.9).  Impression is taken after change in abutment from 6.5x4(4) mm to (5) with prep.  Bone density around the implant at the crest seems to increase 10 months post cementation (Fig.10).  The bone appears to regenerate toward the abutment, particularly distally, 14.5 months post cementation (Fig.12).
