Peri‐implantitis reconstructive treatment implementing a titanium brush: 5‐year extension results from a randomized clinical trial

Treatment of peri-implantitis, specifically reconstructive surgical treatment has been widely investigated. Nevertheless, the paucity of long-term studies reporting on the adjunctive use of a titanium brush in the reconstructive treatment of peri-implantitis underscores the need for further research to validate its effectiveness and long-term benefits. To assess outcomes, stability, and real added benefit of this tool, long term results are of substantial value. Moreover, long-term studies assessing outcomes after reconstructive treatment in peri-implantitis lesions are specially needed taking into account their scarceness in the scientific literature. Five years post-treatment, peri-implantitis reconstructive therapy with a titanium brush showed significant PD reductions (2.86 mm in control, 4.10 mm in test group) and minor bone loss (< 0.5 mm); however, no significant differences were found between groups. Radiographic bone fill was 32.77% in the control group and 54.91% in the test group. Lower bleeding index and daily interdental brush use correlated with better outcomes, indicating sustained improvements. Based on the study's findings, incorporating a titanium brush in the reconstructive treatment of peri-implantitis could enhance long-term outcomes. Highlighting the significance of interdental brush daily use and maintaining a low bleeding index may further improve treatment success.
