68 Chapter 3 Within the successful subgroup a continued reduction after 3 months of therapy was seen for peri-implant parameters BoP, Plq, PPD, and periodontal full mouth BoP and Plq. In addition, successful patients showed lower clinical scores at baseline (BoP, SoP, Plq, PPD, MBL), a shorter implant time in function compared to the overall group and all successful patients were non-smokers. The majority of successfully treated implants at T3 showed 2 out of 6 sites with BoP, with none of the implants showing 5 or 6 out of 6 sites with BoP. Table 6.
