Since the ridge is wide, an extra wide implant is placed (Fig.2: 5.9x10 mm with insertion torque >55 Ncm) with one distal thread exposed (<). ^^: apical gap, which will be closed by further implant torquing (as compared to Fig.5 <). 

The remaining distal exposed thread is covered by autogenous bone harvested during osteotomy (*).  The graft is then covered by collagen dressing, which is held in place by a partially placed healing screw (S).   There is clearance from the Inferior Alveolar Canal (yellow dashed line).
