Methods: Peri-implantitis patients with implant pockets of 5 to 8 mm had subgingival implant surface debridement followed by repeated bi-weekly supra gingival plaque debridement and chlorhexidine chip application for 12 weeks.
Results: A total of 290 patients were included: Significant reduction in implant probing depths was measured in the chlorhexidine group ( 1.76 mm) compared to the control group ( 1.54 mm). Relative attachment gain and gingival recession was also larger in the chlorhexidine group.
Conclusions: Intensive treatment every two weeks comprising of supra gingival plaque removal and chlorhexidine chip application had a greater probing depth reduction compared to plaque removal alone
