Comparing two expanders for crossbite in children
Part of Bones, joints & muscles, Genetic & congenital, Mouth & dental clinical trials.
This trial compares two types of expanders (Leaf Expander vs. Hyrax Expander) to fix crossbites in children who still have some baby teeth. The goal is to see which device works better and is more comfortable.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your child is still in the mixed dentition stage (some baby teeth, some adult teeth).
- Your child has a crossbite (upper teeth sit inside lower teeth) on one or both sides.
- Your child is before or at the start of puberty (confirmed by a neck X-ray).
- Your child's upper and lower first molars (the big back teeth) are fully grown in.
- Your child has a class I or II jaw relationship (normal or slightly forward upper jaw).
- Your child has not had braces or missing teeth, and has no medical conditions or cleft lip/palate.

This trial compares two types of expanders (Quad Helix and RME) to fix back teeth crossbites in children. It looks at which device works best and is most comfortable for young patients.
This trial tests whether adding small plastic bumps, called bite turbos, to a palate expander helps widen the upper jaw better than the expander alone in early teens. This may correct a crossbite, where upper teeth sit inside lower teeth when biting down.
This trial compares a new 3D-printed expander with a standard one to widen the upper jaw in teenagers. It aims to see if the newer device works better or is easier to tolerate.
This trial tests two different dental appliances to fix an open bite in children. It compares a vertical holding appliance to a special arch bar to see which works better.
This study compares a new digital way of making a palatal expander (a device that widens the upper jaw) with the traditional method. It may help children who need a wider upper jaw for better bite alignment.
This trial compares a newer clear palate expander to the traditional Hyrax expander in children aged 10-14 with a crossbite. The goal is to see which device works better and is more comfortable.
