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 . 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 .
