Brief Summary

This prospective study will include patients previously enrolled in the PER-ECL-2019-05 trial who attend the Department of Periodontology (CUO) for maintenance therapy or treatment of periodontal and/or peri-implant diseases, provided they meet the inclusion criteria. Initially, 36 patients with advanced peri-implantitis were enrolled in a randomized clinical trial evaluating the clinical, radiographic and patient-related outcomes of reconstructive therapy following a non-surgical phase of peri-implantitis treatment compared to non-surgical treatment alone (PER-ECL-2019-05) (10). At the study conclusion 34 patients were re-evaluated and 2 patients were excluded from the study (10). In the original study, adult patients presenting at least one titanium implant diagnosed with peri-implantitis were identified among patients referred to the Department of Periodontology of UIC between January 2020 and October 2022. Peri-implantitis was diagnosed following the case definition of the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions (11) that is, PPD ≥ 6 mm combined with bleeding on probing (BOP) and/or suppuration (SUP), together with progressive bone loss in relation to the radiographic bone level assessment. In those cases where initial radiograph was unavailable, the definition of a peri-implantitis case was based on radiographic evidence of bone level ≥3 mm apical to the most coronal portion of the intra-osseous part of the implant (12). At the outset of the original study, participants were randomly assigned to one of two groups: The first group received only non-surgical therapy for peri-implantitis, while the second group underwent a non-surgical phase followed by reconstructive surgical treatment. This design allowed for direct comparison of the clinical, radiographic, and patient-centered outcomes between the two treatment modalities. Both groups were managed and evaluated according to standardized protocols, ensuring consistency and reliability of the results at 12 months . Patients who have not returned to the Department will be contacted by telephone and invited to participate through the academic office. At 36 months, a single follow-up will be carried out including: A detailed clinical examination. A standardized radiographic assessment.

Study Population

Patiens previously enrolled in the randomized clinical trial PER-ECL-2019-05, which included 36 patients with advanced peri-implantitis and treated with non surgical therapy or surgical therapy + reconstructive therapy

You may qualify if:

  • \. Patiens previously enrolled in the randomized clinical trial PER-ECL-2019-05, which included 36 patients with advanced peri-implantitis.
  • \. Completion of the original study protocol, including either reconstructive surgical therapy following a non-surgical phase or non-surgical therapy alone.
  • Signed informed consent for participation in the follow-up assessment.

You may not qualify if:

  • Did not complete the original clinical trial protocol (PER-ECL-2019-05) or withdrew before final evaluation.
  • Had the implant removed due to complications unrelated to peri-implantitis progression.
  • Have developed systemic diseases or conditions (e.g., uncontrolled diabetes, immunosuppression, malignancy) that may affect periodontal or peri-implant tissue healing or confound clinical outcomes.
  • Are currently undergoing antibiotic or antiresorptive therapy (e.g., bisphosphonates) that could interfere with bone metabolism.
  • Are pregnant or breastfeeding at the time of the follow-up visit. 6.Are unwilling or unable to attend the clinical follow-up appointment or provide informed consent.
