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.
Who should consider this trial
Good fit: Adults (≥18) with single-arch or full-arch edentulism who have completed implant placement and immediate restoration, are scheduled for the definitive prosthesis, can perform self-care, and can provide informed consent.
Not a fit: People who smoke ≥10 cigarettes per day, cannot perform prosthesis cleaning independently, have uncontrolled periodontal disease in remaining teeth, or have failed implants requiring reimplantation are unlikely to be eligible or to benefit.
Why it matters
Potential benefit: If successful, the results could identify the best cleaning tool to reduce plaque and lower the risk of peri-implant biological complications, helping implants last longer.
How similar studies have performed: Similar tools are commonly used and have shown benefit in small or laboratory studies, but in vivo randomized comparisons with long follow-up are limited.
