A 5x11.5 mm implant is placed with insertion torque of 35 Ncm with ~ 2 mm sticking into the sinus with bone graft and 1.5-2.5 mm outside the septum.  The latter is covered by bone graft (Fig.10 *).

Four months postop, the native bone appears to be approaching the implant surface (Fig.11 >).

The patient experiences palatal gingival tenderness 5 months post cementation, probably due to loose proximal contacts and excessive use of floss.  PA shows new normal bone next to the upper threads (Fig.12 arrow), while new less dense attached to the most coronal threads (*).
