Cleaning tools for full-arch implant-supported fixed prostheses

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized controlled trial assigns adults with single-arch or full-arch implant-supported fixed prostheses to use Superfloss, interdental brushes, or a water flosser. Participants receive standardized instructions and are followed over a relatively long observation period to measure plaque accumulation, peri-implant biological signs, and hygiene outcomes. Clinical examinations and objective plaque measurements will be used to compare the real-world cleaning effectiveness of each tool. The aim is to identify the most effective routine cleaning approach to reduce plaque-related complications and support long-term prosthesis success.
