Can a dental compass cut radiation and improve TMJ splints?
NCT ID NCT06619574
First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This trial tests whether a dental compass and its software can create more accurate therapeutic splints for people with temporomandibular joint (TMJ) dysfunction and pain. It compares a group using this 3D-guided method to a group using manual fabrication, looking at the number of clinic visits, splint adjustments, and cone beam CT scans needed. The goal is to see if the compass approach improves joint positioning while reducing radiation exposure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dental Compass Articulator and software for therapeutic splint fabrication
- What this could lead to
- If effective, this approach could make TMJ splints more accurate with fewer visits and less radiation exposure.
- What could go wrong
- This is a small, early comparison study. The dental compass may not prove superior to manual methods, and results may not apply broadly.
