Could a light zap save your dental implant?
NCT ID NCT07191522
First seen Nov 01, 2025 · Last updated Jun 22, 2026 · Updated 31 times
Summary
This study tests whether adding a special light therapy (photodynamic therapy) to standard deep cleaning helps treat peri-implantitis, an infection around dental implants that can lead to implant loss. Forty adults with infected implants will receive either standard cleaning alone or cleaning plus the light treatment. Researchers will measure gum pocket depth and other signs of infection after 6 weeks to see if the light therapy improves healing.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
antimicrobial photodynamic therapy (aPDT) using a light-sensitive compound and light
What this could lead to
If it works, this could offer a better non-surgical way to treat gum infections around dental implants, potentially saving more implants from being lost.
What could go wrong
This is a small, early-stage trial with only 40 participants and a short 6-week follow-up. The added benefit of photodynamic therapy over standard cleaning alone may be small or not last long.
