Digital vs. direct: which method places jaw screws more accurately?
NCT ID NCT07707596
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This trial compares two methods for placing tiny screws in the roof of the mouth (palatal miniscrews) to help widen the upper jaw in teenagers. One method uses the expansion device itself as a guide, while the other uses a custom 3D-printed guide based on digital planning. The study measures how accurate, stable, and safe each approach is using post-procedure scans.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- a procedure comparing direct appliance-guided versus digitally guided CAD/CAM surgical guide for palatal miniscrew placement
- What this could lead to
- If one method proves more accurate and safer, it could become the standard approach for palatal miniscrew placement in teens needing jaw expansion.
- What could go wrong
- This is a small, early-stage study (40 participants) comparing two techniques, so results may not apply to all patients or settings. Both methods carry risks like screw failure or sinus penetration.
