Purpose: The aim of this study was to evaluate cleaning effectiveness of glycine powder air-polishing when applied on implant-supported full-arch restorations without removal of the fixed prosthesis. Materials and Methods: 85 patients with a total of 357 implants supporting full-arch fixed rehabilitations were included. After removal of the prosthesis (T0) these parameters were recorded: plaque Index (PI), peri-implant spontaneous bleeding (SB), probing depth (PD), bleeding on probing (BOP). The prosthesis was then screwed again. Patients were divided in three groups, each including two hygienic therapies, randomly administered on each hemiarch, according to a split-mouth design. The feasible treatments were: glycine air-polishing (G) and use of sponge floss vs dental sponge floss only (S) in Group 1; G vs ultrasonic device with a PEEK fiber t.. View More»
