Continuously alternating use of MEs and drills leads to placement of a 5x11 mm implant with 30 Ncm insertion torque and sinus lift.  After placement of bone graft (Fig.8 *) and 5x4(3) mm pair abutment (A), an immediate provisional is fabricated.   Fig.9 is a PA taken higher than Fig.8 to show the sinus floor and the mesial wall of the socket (red dashed line).

It seems that the provisional traps food.  The former has been removed by the patient by the time she returns 3.5 months postop.  The gingiva around the implant is healthy.  The organization of the bone graft has changed (Fig.13, as compared to Fig.8,9).  The implant has osteointegrated.

The crown dislodges 8 months post cementation, probably due to bruxism, small, short abutment and open margin (Fig.15 (taken after recementation; the residual cement is removed later)).
