When a 7x17 mm implant is placed (Fig.6 I), there is a fairly sized and circumferential gap (*) which is filled with mixture of autogenous bone (from reamers), mineralized cancellous allograft and Osteogen.  If a larger implant were used (e.g., 8x17 mm), the amount of bone graft used would have been less.  It would also take less time for our body/bone to fill the gap.  The abutment (A) is temporarily placed to hold perio dressing in place as securely as possible.
