To accommodate the cross bite, the coronal portion of the 4x15 mm implant is positioned close to the socket shield (Fig.9).  It appears that the shield prevents the implant from encroaching the buccal plate.

The abutment at #6 is 4.5x5.5(4) mm.  The 2.5x14 mm 1-piece implant is placed deeper than earlier (Fig.10).
