New study tests better ways to fix overbite without surgery
NCT ID NCT07307209
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two methods to move the entire upper row of teeth backward in adults with a type of overbite called Class II malocclusion. Both methods use small screws placed in the cheekbone area for support. The goal is to see which method works faster, causes fewer side effects, and is more comfortable for patients.
