Background The aim of this study was to compare different surgical therapies to treat peri‐implantitis. Methods Twenty‐three patients presenting one implant affected by peri‐implantitis were divided into three groups: (i) open flap debridement ( OFD ) and citric acid decontamination ( CAD ); (ii) O FD , CAD and subepithelial connective tissue graft ( SCTG ); (iii) O FD , CAD and implantoplasty. Modified plaque index ( MPI ), gingival bleeding index ( GBI ), keratinized mucosa ( KM ) width, probing depth ( PD ), bleeding or suppuration on probing (B/ SOP ), and radiographic crestal bone level were registered 1(T1), 2(T2) and 3(T3) years after treatment. Results In Group 1 there was a significant improvement in MPI from baseline to T1, and a significant reduction in PD over time. In Group 2, none of the assessed clinical parameters showed any statistically significant variation over time. In Group 3, there was a significant decrease in PD and B/ SOP over time. When comparing the 3 Groups, KM was significanlty greater in Group 2 vs. Group 1 and Group 3 at T1 and T2, and in Group 2 vs. Group 3 at T3. Conclusion All therapies were successful in the management of peri‐implantitis; however, SCTG maintained the greatest KM width. Surgical therapies combined with mechanical and chemical decontamination contributed to peri‐implant tissue health.
