Comparing two expanders for crossbite in children
Part of Mouth & dental clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part

- They cannot have had braces or other orthodontic treatment before.
- They must have good oral hygiene and be able to cooperate with treatment.

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.
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 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 two treatments for children whose upper jaw is smaller than their lower jaw. One is a plastic expander, the other is an expander with a facemask. Both aim to fix the bite and help the upper jaw grow properly.
This trial tests different methods to widen a narrow upper jaw and see how they affect the nose and face bones. It is for people 15 and older who have a crossbite (when upper teeth sit inside lower teeth).
This trial tests a device to widen a narrow upper jaw using small anchors in the bone. It is for adolescents and adults who have a crossbite and a narrow upper jaw caused by bone structure, and who have never been treated before.
