Expanding the upper jaw to fix a narrow bite
Part of Bones, joints & muscles, Mouth & dental clinical trials.
This study tests a device that gently widens the upper jaw to fix a narrow bite. It may help reduce crowding, crossbite, or breathing issues without surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your upper jaw is too narrow (a constricted maxilla), which may cause your back teeth to cross.
- You have a crossbite on one or both sides of your mouth.
- You keep your teeth and gums clean and are generally healthy.
- You have not had braces or other tooth-moving treatment before.
- You do not have a long-term health problem that weakens bones or affects healing.
- You are an adolescent or adult (no specific age limit was given).
