Could a simple screw choice reduce orthodontic complications?
NCT ID NCT07761494
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This trial investigates whether the method of inserting orthodontic miniscrews (self-drilling vs. self-tapping), along with patient sex and jaw location, influences the risk of complications like inflammation, pain, root damage, or screw failure. The study involves adults aged 20-40 with Class II malocclusion who need miniscrews to support tooth movement. By identifying risk factors, the goal is to improve the safety and comfort of this common orthodontic procedure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Orthodontic miniscrew insertion using self-drilling method
- What this could lead to
- If successful, this could help orthodontists identify patients at higher risk for complications and choose safer insertion techniques, reducing pain and implant failure.
- What could go wrong
- This is a single-center study, and results may not apply to all populations. Complications like root perforation or implant fracture are rare, so the study may not have enough power to detect significant differences.
