NCT ID NCT07485478
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares the Invisalign Palatal Expander (IPE) with the Rapid Palatal Expander (RPE) in children aged 8–12 who have a narrow upper jaw and an underbite (skeletal Class III). Participants will wear a facemask after expansion. Researchers use 3D X-rays to measure changes in jaw bones and tooth position, and also interview children and parents about their experience. The goal is to see which device works better and is more comfortable.
