The second design is to place relatively smaller implants with the occlusion in mind (Fig.4).  The starting point for the osteotomy will be as lingual as possible.  The axis of the implant will be more parallel to the buccal plate.  The angles of the angled abutments will be less (vs. Fig.2).  The cosmetic result may be better.
