CT taken 2 years 7 months post cementation (Fig.35) shows that the buccal plate (B) covers the 3x14(2) mm implant; although the thicker palatal bone (P) is shy of the implant, the thicker palatal gingiva (G) covers the exposed threads and the cuff of the abutment.  This is the basis for lack of periimplantitis.
