About this study
The surgical treatment outcome of patients that have been or are consecutively treated at the University of Malmö, at Blekinge hospital, and at the Dental Clinic of the Sigmund Freud University Vienna will be evaluated on an a regular base; specifically all patients treated since 2014 and those receiving treatment in the future, will be regularly assessed, max. once per year after the 1-year control from the surgical intervention for clinical and radiographic assessment of healing. Clinical peri-implant parameters (e.g., probing pocket depth) and peri-implant sulcus fluid (PISF) are collected, and a peri-apical radiographic examination is made. Further, from 200 patients treated in the future, the inflammatory peri-implant lesion will be collected and subjected to histological, microbiological, and molecular analysis. The removal of these lesions is a standard procedure and performed in all patients independent of study participation; i.e., the lesion has anyway to be removed during surgery and if the lesions are not stored, they would be thrown.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease resolution (Binary: yes/no) (time frame: 12 months postoperative). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Feb 2024; AzTrials last refreshed its copy on 8 Nov 2026.
