New gel could help save failing dental implants
NCT ID NCT06914518
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether a gel made from polynucleotide and hyaluronic acid can improve treatment for peri-implantitis, a gum infection around dental implants. Thirty-two adults with infected implants will receive standard deep cleaning plus either the gel or a placebo. The main goal is to see if the gel reduces pocket depth around the implant after 6 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Polynucleotide and hyaluronic acid gel (PN-HA)
- What this could lead to
- If it works, this gel could improve gum healing around dental implants and reduce the need for more invasive surgery.
- What could go wrong
- This is a small, early-stage trial with only 32 participants and a short 6-month follow-up. The gel may not provide significant benefit over standard cleaning alone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Subjects with (I) ≥ 18 years of age, the presence of at least one implant diagnosed with peri-implantitis, intraosseous ≥ 3mm defects, presence of screw-retained single-unit crowns and partial dental prosthesis that allowed correct access for brushing; and, if not, prostheses that could be modified. Exclusion Criteria: Subjects will be excluded from the study if they had received previous non-surgical peri-implantitis treatment during the last 6 months or surgical treatment, were pregnant or breast-feeding, had received antibiotic treatment in the previous 3 months, had systemic conditions that contraindicated treatment, smoking more than 10 cigarettes/day or presents a poor plaque control (Plaque Index \< 20%), implant mobility.
