Treatment of peri-implantitis by the Vector system.

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) > or =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.
