Aim: To compare the effectiveness of treatment of peri‐implantitis with a novel ultrasonic device, the Vector ® system, with that of subgingival debridement with carbon fiber curettes. Material and methods: The study, comprising 11 patients with at least two screw type implants with bleeding on probing (BOP), probing pocket depth (PPD)≥5 mm, and at least 1.5 mm radiographic bone loss and exposed implant threads, was carried out as a single blind randomized clinical trial. At baseline one randomly chosen implant in each patient was treated by the Vector ® system (test) while the other implant (control) was treated by submucosal debridement with a carbon fiber curette. After 3 months, the same treatments were repeated. Plaque, BOP, and PPD were recorded on all implant surfaces at baseline, and after 3 and 6 months. Bone levels were recorded on radiographs taken prior to the start of the study, and after 6 months. Results: Oral hygiene around both test and control implants was improved at 3 and 6 months compared with baseline. At 6 months, four of the Vector ® ‐treated sites, and only one site treated with curettes, had stopped to bleed. In neither the test nor the control group, were there any differences between baseline and 6 months regarding PPD and bone levels. Conclusion: Although there was a greater reduction in the number of sites with BOP following treatment with the Vector ® system than following instrumentation with carbon fiber curettes, there was no significant difference between the two methods.
