Bone expansion and bending (BEB) continues until 4.3 mm ME; a 4.3 mm Magic Drill (MD) is used for depth (13 mm gingival level). A 4.5x11 mm dummy implant is placed 2 mm subgingival (Fig.2). The buccal crest (white dashed line) is lower than the lingual one (arrows). A definitive implant should be placed around the level of the buccal crest. Red dashed line: the superior border of the Inferior Alveolar Canal.
