Does your Aligner's edge matter? new study tests gum health
NCT ID NCT07642037
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 2 times
Summary
This study looks at two different ways clear aligners are trimmed—one that sits on the gums and one that stops at the gum line—to see which leads to less plaque and healthier gums. Twenty adults with mild to moderate crowding will wear both designs at the same time (one on top, one on bottom) and be checked over six months. The goal is to help orthodontists choose the better design for gum health.
