Tiny lab test hopes to improve bone grafting for tooth loss

NCT ID NCT04964466

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This lab study compares how much growth factor (PDGF-BB) is released over time from two materials used in bone grafting: platelet-rich fibrin (PRF) from a patient's blood and a commercial product called GEM21S. Researchers will mix these with bone substitutes and measure growth factor levels at several time points. Only 5 samples are being tested, so this is early-stage knowledge gathering, not a treatment trial.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Platelet-rich fibrin (PRF) and recombinant human platelet-derived growth factor-BB (rhPDGF-BB, GEM21S)

What this could lead to

If successful, this could help dentists choose the best way to deliver growth factors for bone healing procedures.

What could go wrong

This is a very small lab experiment with only 5 samples, not a patient trial. Results may not translate to real-world healing.
