The mesiodistal space allows to place a 5x14 mm implant (Fig.2 design).  Bone density is felt low when a 1.6 mm pilot drill is used.  Bone condensation proceeds with bone expanders from 2.6 mm (Fig.3) to 3.8 mm (Fig.4) 12 mm deep.  Bone density is felt to increase with each larger expanders. 1.4 mm refers to the apical diameter of the bone expander.
