The ridge at the site of #2 is mild to moderately atrophic. While a straight incision ~ 9 mm long is being made over the ridge, the underlying bone feels soft. The #15 blade is tapped in to start bone expansion, followed by RT 2-4 and 4.5x11 mm tap at 8 mm at gingival level (Fig.1 T). Allograft and Osteogen is placed in the osteotomy and pushed upward by re-inserting the 4.5x11 mm tap. More bone graft is pushed superiorly by inserting 5x11 mm tap. A 5.3x8 mm bone-level implant is placed with insertion torque of >50 Ncm with sign of sinus lift (Fig.2).
