Growth factor may boost bone healing for dental implants
NCT ID NCT04954664
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a growth factor (rhPDGF) to a standard bone graft helps rebuild jawbone better than using saline alone. About 44 adults who need dental implants but have thin jawbone will receive one of the two treatments. Researchers will measure new bone formation after 4 months using scans and tissue samples.
