Abstract Objective To evaluate clinical and radiographic characteristics in peri‐implant marginal tissues in patients with a history of chronic periodontitis, rehabilitated using tissue‐level or bone‐level implants. Material and Methods Using a split‐mouth design, 20 patients with a history of chronic periodontitis were selected and received two different implants, tissue‐level group ( n = 20) and the bone‐level group ( n = 20). Peri‐implant probing depth, relative peri‐implant mucosal margin position, relative peri‐implant clinical attachment level, peri‐implant plaque index and peri‐implant bleeding on probing were evaluated at prosthesis installation, 1, 3, 6, 12 and 24 months after implant loading. Radiographic marginal bone level was evaluated at implant insertion, prosthesis installation, 6 and 24 months after implant loading. Results The mean difference of peri‐implant marginal bone resorption from implant installation to 24 months in function was 0.75 ± 1.12 mm for the tissue‐level group and 0.70 ± 0.72 mm for the bone‐level group. No statistically significant difference was found between groups at all assessment periods for clinical and radiographic peri‐implant evaluation. Conclusion Under a rigid supportive therapy, both approaches performed likewise regarding clinical and radiographic parameters for rehabilitation of patients with a history of chronic periodontitis.
