Own bone mixed with cow bone may improve dental implant success
NCT ID NCT07177495
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests two bone graft materials for sinus lifts in people with a thin upper jaw who need dental implants. One group gets a 1:1 mix of their own bone and cow bone granules; the other gets cow bone alone. The goal is to see which leads to better bone growth, measured by CT scans. The trial is small with 26 participants and is currently recruiting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mixture of autogenous bone (patient's own bone) and deproteinized bovine bone particulate (cow bone granules)
- What this could lead to
- If successful, this could show that mixing a patient's own bone with cow bone leads to better bone growth for dental implants in the upper jaw.
- What could go wrong
- This is a small, early-stage trial with only 26 people, so results may not apply to everyone. The procedure carries standard surgical risks like infection or sinus issues.
