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.
Bone density around the implant increases 8 months postop (3.5 months post cementation, Fig.8 *), although there is tenderness buccal to #19. Amoxicillin is prescribed.
