Tiny implants, big smile: short teeth screws could replace bone grafts
NCT ID NCT02877433
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether very short (4 mm) dental implants can securely hold a full set of fixed false teeth in the lower jaw. Fifty-three adults with no teeth in the lower jaw received either two or four short implants at the back, plus standard-length implants at the front. The goal was to see how well the implants stayed in place over time, offering a simpler option for people with thin jawbone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Roxolid short dental implant (4 mm length)
What this could lead to
If successful, this could offer a less invasive option for people with jawbone loss to get stable, fixed dentures without needing bone grafts.
What could go wrong
This is a small, completed study with only 53 participants. Short implants may not be as durable as standard-length implants, and individual results may vary.
