Drill/reamers have to be used to create osteotomy at the site of #15 (palatally) before re-insertion of the 5x17 mm tap with stability (Fig.3).  Note the mesial gap (*); when a 6x17 mm tap is inserted, the mesial gap still exists.  It disappears when a 7x17 mm tap is placed.  Therefore a 7x14 mm implant is placed with insertion torque > 60 Ncm (Fig.4 I).  A: abutment (6x3 mm): ^: sinus floor.
