Summary

This study tested three different sizes of clear aligner attachments (small bumps on the teeth) to see which one helps move the upper lateral incisors outward most predictably. Twenty-eight people with mild crowding or spacing were treated with Invisalign. The goal was to find the attachment size that gives the most accurate tooth movement, potentially reducing the need for extra refinement trays.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: clear aligner attachments (gingivally beveled 1x1x3 mm, 1x1x4 mm, or 1x1x5 mm)
What this could lead to: If successful, this could help orthodontists choose the best attachment size for more predictable tooth movement with clear aligners.
What could go wrong: This is a small, completed study with only 28 participants, so results may not apply to all patients. It focuses on one specific tooth movement, not overall treatment success.
