When a 5x11.5 mm implant is placed at the site of #19 with 50 Ncm (Fig.5 I), there is minimal bone left distal to the tooth #20 (small *).  Mixture of autogenous bone and allograft (.5-2 mm, Fig.6 large *) is placed in the remaining bony defects before and after placement of a 7.5x4(4) mm abutment (A).  The bone graft (Fig.7 large *) remains in place 4.5 months postop.  More amazing is that there is formation of new bone distal to the tooth #20 (small *).  The patient does not complain of tenderness of this premolar any more.
