New gum surgery aims to fix 'Black Triangles' around dental implants
NCT ID NCT07204353
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two surgical techniques to rebuild the small triangle of gum (papilla) that is often missing around single-tooth dental implants in the front of the mouth. Eighty adults with gum loss around an implant received either a standard incision, a modified flap procedure, or that flap plus a gum graft. The goal was to see which method best restores gum height and fullness, with results checked up to six months after the final crown was placed.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surgical procedure (modified labial pedicle papilla flap with or without de-epithelialized gingival graft)
- What this could lead to
- If successful, this could offer a reliable surgical option to restore gum shape around dental implants, improving smile aesthetics.
- What could go wrong
- This is a small, completed trial with 80 participants, so results may not apply to everyone. Surgery carries risks like infection, swelling, or incomplete gum regrowth.
