Could a special gel help dental implants take root better?
NCT ID NCT07150858
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether adding erythropoietin to a platelet-rich fibrin gel helps bone grow better during sinus lifting for dental implants. Twenty adults with low bone height in the upper jaw will receive either the erythropoietin-enhanced gel or the standard gel during implant placement. Researchers will measure pain, swelling, implant stability, and bone gain over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- erythropoietin and albumin platelet-rich fibrin gel
- What this could lead to
- If it works, this could improve bone healing and implant stability for people needing dental implants in the upper jaw with low bone height.
- What could go wrong
- This is a very small early study with only 20 participants, so results may not apply widely. The added benefit of erythropoietin over the standard gel is uncertain.
