Which clear aligner holds up better? new study puts materials to the test
NCT ID NCT07566533
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at two types of clear aligners used to straighten teeth: single-layer and triple-layer plastic sheets. 66 people wore them for 10 days, and researchers tested how the aligners' strength, flexibility, and surface changed. The goal is to see which material holds up better inside the mouth, which could lead to more effective orthodontic treatment.
