Summary

This prospective cohort study evaluated the effect of periodontitis grading on peri-implant clinical and radiographic outcomes over a 60-month follow-up. Fifty-five partially edentulous patients were classified into three groups according to periodontal status: generalized aggressive periodontitis (Grade C), generalized chronic periodontitis (Grade B), and no history of periodontitis. A total of 92 implants (tissue- or bone-level) were placed and restored with single crowns, followed by biannual supportive periodontal therapy.

Peri-implant clinical parameters (probing depth, clinical attachment level, plaque index, and bleeding on probing), marginal bone level changes, peri-implantitis incidence, and implant survival were assessed up to 60 months after prosthetic loading.

The objective was to determine whether periodontal history and grading influence long-term peri-implant outcomes under maintenance therapy.
