Air-polishing in the treatment of peri-implantitis - a randomized controlled trial
NCT ID NCT04847648
First seen Sep 09, 2026 · Last updated Sep 09, 2026
Summary
The aim of the present study is to evaluate the potential benefit of the adjunctive use of an air-polishing device in the non-surgical treatment of peri-implantitis as compared to mechanical infection control alone. Following establishment of adequate patient-performed infection control, 80 patients diagnosed with moderate/severe peri-implantitis at ≥1 implant will be randomized to one of two groups. Non-surgical will be carried out by experienced operators in three clinical centers and the mechanical instrumentation (control group) will be supplemented by the use of air-polishing with erythritol powder (AirFlow Master, EMS, Nyon, Switzerland) in the test group. The primary outcome assessed is "pocket closure" (ie probing pocket depth ≤5 mm \& absence of profuse bleeding on probing) after 6 months. Secondary outcomes include changes of clinical signs of soft tissue inflammation, adverse events and patient-reported outcome measures. Outcomes of non-surgical therapy will be evaluated at 3 and 6 months. Sites with remaining pathology at 6 months will be subjected to surgical therapy. Patients are then provided with personalized maintenance care and followed up to a 5-year evaluation.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Probing pocket depth of ≥6 mm * Bleeding and/or suppuration on probing at ≥3 aspects per implant * Documented radiographic bone loss of ≥2 mm. Exclusion Criteria: * Implants with bone loss ≥80% of implant length will not be considered. * No medical conditions prohibiting non-surgical/surgical treatment of peri-implantitis * Implant(s) in function ≥1 year
