After finishing osteotomy according to the guide plan, a 3.5x13 mm drill is used ~ .5 mm shy of the depth without sign of sinus membrane leakage.  The implant is placed with apparently satisfactory depth, but it is quite close to the curved root tip of the neighboring tooth (Fig.2,3).  The implant is stable for impression 6.5 months postop (Fig.5), whereas that placed immediately free hand is unstable 7.5 months postop.
