Tooth tilt may predict jaw widening success
NCT ID NCT07095374
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 200 people with a narrow upper jaw who are getting a palate expander. Researchers want to see if the angle of the premolars on X-rays can predict how much the jaw will widen. The goal is to better understand the treatment process, not to test a new therapy.
