A 1.5 mm pilot drill is used to start osteotomy at 17 mm (gingiva level; Fig.3); it appears that a longer implant is possible (arrowhead: presumptive nasal floor).  The osteotomy is then moved distal before using 2, 3 and 3.2 mm drills at 18 mm (bone level).  A 4x18 mm implant is placed (>50 Ncm) with a 4.5x5(3) mm abutment (Fig.4).
