New bracket design tested to speed up tooth movement in braces
NCT ID NCT06481761
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether double-slot brackets move canine teeth faster than standard single-slot brackets after premolar extraction. Thirty patients were randomly assigned to one bracket type, and tooth movement was tracked monthly using digital models and 3D scans. The goal is to see if the double-slot design offers a more controlled or quicker retraction.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Double-slot brackets and single-slot brackets (orthodontic devices)
- What this could lead to
- If double-slot brackets prove faster or more controlled, orthodontists may adopt them to shorten treatment time for canine retraction.
- What could go wrong
- This is a small, completed trial with only 30 participants, so results may not apply to all patients. The difference between bracket types may be small or not clinically meaningful.
