Resumo

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 MethodsResultsUsing 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 24months after implant loading. Radiographic marginal bone level was evaluated at implant insertion, prosthesis installation, 6 and 24months after implant loading. The mean difference of peri-implant marginal bone resorption from implant installation to 24months in function was 0.751.12mm for the tissue-level group and 0.70 +/- 0.72mm for the bone-level group. No statistically significant difference was found between groups at all assessment periods for clinical and radiographic peri-implant evaluation. ConclusionUnder a rigid supportive therapy, both approaches performed likewise regarding clinical and radiographic parameters for rehabilitation of patients with a history of chronic periodontitis.
