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^).   After changing to 6.5x6(2) mm abutment, a new provisional is fabricated so that it can undergo progressive loading for a few months before final impression.  The definitive restoration is delivered 7.5 months postop (Fig.5).  The bone density apical to the implant becomes apparently denser nearly 5 months post cementation (Fig.6).  The bone density in the crest increases 2 years post cementation (Fig.7 *).
