de Tapia B, et al. - Researchers performed a randomized double-blinded clinical trial, with a 1-year follow-up, to determine the effect an additional mechanical approach, a titanium brush, in the implant surface decontamination performed during the regenerative surgical therapy of peri-implantitis. They included 30 patients and randomly assigned 15 to control and 15 to test group. They decontaminated implant surface both mechanically and chemically with 3% H₂O₂ and plastic ultrasonic scalers, respectively, in the control group, while a titanium brush was applied in addition in the test group. Findings revealed statistically significant benefits in terms of probing pocket depth reduction after 12 months when titanium brush was applied during regenerative treatment of peri-implantitis.
