Fig.9 (immediately postop PA): The crown of the tooth #8 (C) is modified to be used as an immediate provisional.  The mesial margins of the neighboring teeth are even.  *: allograft.  Implant: 3.8x13 mm, >35 Ncm; abutment: 5.5x5.5(4) mm.  Note that the bone graft does not reach the most coronal threads of the implant, because the wide abutment interferes with bone graft placement.  It is better to place bone graft prior to abutment placement.  But a healing screw should be placed to prevent entrapment of bone graft into the implant well.

The crown shell remains in place, although fractured in the mesial margin (Fig.12 >) 2.5 months postop.

Partial Clearance Last Next 2 Years 5 Months Post Cementation
