How can the narrow implant achieve such high torque value?  After ridge top trimming (Fig.6 green line), it is difficult to extend the 1.6 mm pilot drill (Fig.6 red line) for the last few mm.  The drill must encounter the lingual cortex (L).  When the 4x11 implant (Fig.5 green box) is placed, it must contact both the crestal (C) and lingual cortices.
