Can a new drilling technique make dental implants safer for people with thin jawbone?
NCT ID NCT07719283
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
This trial tests two methods of sinus floor elevation—a procedure to create bone for dental implants in the upper jaw—in people with only 4-5 mm of bone below the sinus. One method uses a special rotating bur (osseodensification), the other uses manual tools (osteotomes). All procedures are monitored with a tiny camera (endoscope) to reduce the risk of tearing the sinus membrane. The goal is to see which technique leads to better bone healing, implant stability, and patient comfort.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- osseodensification drilling technique and osteotome technique for sinus floor elevation
- What this could lead to
- If osseodensification proves superior, it could offer a safer, more comfortable way to place dental implants in patients with limited sinus bone, reducing complications like membrane perforation.
- What could go wrong
- This is a small, early-stage trial with only 44 participants, so results may not apply broadly. Both techniques carry risks such as infection, bleeding, or implant failure.
