Collagen plug is used to repair the perforation before placing a short (5x7 mm) IBS implant with ~ 25 Ncm (Fig.2).  After placing a 6.5x5.7(3) mm abutment, allograft is placed around the most coronal exposed implant thread (^). 

New bone forms apically and coronally 4.5 months postop (Fig.3,4 ^).   After changing to 6.5x6(2) mm abutment, a new provisional is fabricated.
