Background: The aim of this prospective study is to evaluate the prevalence of mucositis, peri‐implantitis, implant success, and survival in partially edentulous patients treated for generalized aggressive periodontitis (GAgP) and in periodontally healthy individuals. Methods: Thirty‐five patients treated for GAgP and 18 periodontally healthy patients orally rehabilitated with osseointegrated implants participated in the study. They were first examined 2 to 4 weeks before extraction of the non‐retainable teeth (baseline) and 3 weeks after insertion of the final abutments. Additional examinations were performed during a 3‐month recall schedule over a 5‐ to 16‐year period (mean, 8.25 years). At every session, clinical parameters were recorded. At 1, 3, 5, 10, and 15 years after insertion of the superstructure, a microbiological and radiographic examination was performed. Results: The results show implant survival rates of 100% in periodontally healthy individuals versus 96% in GAgP patients. The implant success rate was 33% in GAgP patients and 50% in periodontally healthy individuals. In GAgP patients, mucositis was present in 56% and peri‐implantitis in 26% of the implants. In periodontally healthy individuals, 40% of the implants showed mucositis and 10% peri‐implantitis. GAgP patients had a five times greater risk of implant failure, a three times greater risk of mucositis, and a 14 times greater risk of peri‐implantitis. Conclusion: These results suggest that patients with treated GAgP are more susceptible to mucositis and peri‐implantitis, with lower implant survival and success rates.
