Following 4.8 mm drill, a 5.5x11.5 mm implant is placed initially (Fig.3) with an apical space (*) and clearance between the osteotomy and the Inferior Alveolar Canal (red dashed line).  The implant is placed deeper with placement of a 6.5x4(5) mm abutment and bone graft (*, Fig.4).  There is no bone loss 3.5 months postop (Fig.8).  The abutment margin is lowered by prep before impression.  In fact the abutment has not been seated completely since its placement (Fig.4,5,8).
