1st Case of CMC

Four months post bone graft, the bone height at #14 is ~ 5 mm (Fig.1).  After osteotomy for 4 mm with 4.3 mm Magic Drill (hard bone), Magic Sinus Lifter is used for sinus lift for ~ 8 mm without sinus membrane perforation.  Perforation occurs with pulsating hemorrhage after sinus lift with allograft (.5-1 mm, mixed with Metronidazole).  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 (^).  Acrylic is applied over the abutment for wound protection.  There is mild nasal hemorrhage for 2 days postop. To prevent and treat sinus membrane perforation, PRF will be routine prepared preop for future cases. New bone forms apically and coronally 4.5 months postop (Fig.3,4 ^).  A new temporary crown 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 *).
