Magic Sinus Lifter is used to elevate the sinus floor for ~ 5 mm, followed by insertion of allograft/Osteogen and 4.0x11 mm dummy implant partially (Fig.1).  With approximately 10% more of graft being placed, a 4.5x9 mm IBS implant is placed with insertion torque of 15 Ncm (Fig.2).  The implant has a tenting effect.  The bone graft appears to move distal 1 month 20 days postop (Fig.5 arrow), while the implant seems to be extruded with implant exposure.  The patient feels pain when the healing screw is being removed or tightened.  The distal migration of the bone graft may lay foundation for future implant placement at #15.  Can the implant at #14 be retorqued to be seated deeper 3-4 months later?  Bone density around the implant remains the same (Fig.6), while the wound reduces nearly 3.5 months postop (Fig.7).
