Recruiting studies
- NCT07411092Recruiting
3D-printed expander vs. traditional expander for widening the upper jaw in teens
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.
Cairo, Cairo GovernorateAges 12–17 - NCT07326345Recruiting
Study comparing ways to widen the upper jaw
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).
Istanbul, FatihAges 15 years+ - NCT06187337Recruiting
Expanding the upper jaw to fix crowded front teeth in children
This trial tests if expanding the upper jaw can make room for crowded front teeth in children who still have some baby teeth. It aims to help the side front teeth come in properly without needing braces later.
CoppitoAges 6–16 - NCT07095374Enrolling by invitation
How jaw widening affects premolar tilt
This study looks at how widening the upper jaw with a special device (rapid palatal expander) affects the tilt of certain teeth (premolars). It may help doctors understand how to plan better orthodontic treatments.
Pavia, LombardyAges 6–14 - NCT07262892Recruiting
3D study of jaw widening methods in children
This trial uses 3D imaging to compare two ways of widening the upper jaw in children. It may help your child if they need jaw expansion and haven't had it before.
Istanbul, FatihAges 6–12 - NCT06246656Recruiting
Maxillary expansion with a custom 3D-printed appliance
This trial tests a computer-designed device to widen the upper jaw. It may help people with a narrow upper jaw or a crossbite (when upper teeth sit inside lower teeth).
Vienna, State of ViennaAges 12–26 - NCT06449014Recruiting
Mini-implant palate expander for teens and adults
This study tests whether a new type of palate expander that uses small implants (mini-screws) can safely widen the upper jaw in people 16 and older. It may be an option for you if your upper jaw is too narrow, even if you have already stopped growing.
Anderlecht, Brussels CapitalAges 16 years+ - NCT06864949Enrolling by invitation
Expanding the upper jaw with a preformed brace
This study tests a preformed appliance designed to widen a narrow upper jaw. It may help people whose upper jaw is too narrow, causing their back teeth to cross or tilt inward.
Pavia, LombardyAges 7–13 - NCT04190953Recruiting
Braces and expanders in kids to improve airflow space
This study looks at how jaw and palate treatments affect airflow through the upper airway in children with a specific bite and jaw shape. It may help researchers understand which treatments improve space for breathing and related pressure changes.
Edmonton, AlbertaAges 8–14 - NCT07739498Recruiting
Bite turbos with palate expander for teenagers
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.
Al MansurahAges 10–14 - NCT06725979Recruiting
Palatal expansion for sleep disorders in children
This trial tests if a treatment that widens the upper jaw (palatal expansion) can improve sleep problems in children who have a narrow upper jaw.
Rijeka, Primorje-Gorski Kotar CountyAges 2–18 - NCT06994754Recruiting
Expanding the upper jaw with clear aligners in cleft lip and palate patients
This trial tests whether clear aligners can safely widen the upper jaw in children with cleft lip and palate who still have some baby teeth. It may be an option for those needing jaw expansion without braces.
Cairo, SelectAges 6–12 - NCT05743127Recruiting
3D-printed vs lab-made braces expanders for kids
This study compares two types of orthodontic expanders—one made with 3D printing and one made in a lab—to see which works better for widening the upper jaw. It may help your child’s orthodontic team learn the best option for correcting a narrow upper palate.
Pittsburgh, PennsylvaniaAges 8–13 - NCT07031349Recruiting
Sleep and airway changes from palate expander treatment
This study tests whether a special palate expander (MARPE) improves sleep and airway function in teenagers with a narrow upper jaw. It may help breathing during sleep.
Konya, MeramAges 15–18 - NCT07331207Recruiting
3D-printed expander for narrow upper jaw in young adults
This study tests a new 3D-printed expander that attaches to bone to widen a narrow upper jaw in young adults. It may help if you have a crossbite or need more room in your upper jaw.
Al MansurahAges 18–30 - NCT06943443Enrolling by invitation
Vitamin D and expander treatment for teens
This trial looks at whether vitamin D levels affect how well a special expander (MARPE) works to fix a narrow upper jaw in teens. If you are 15–18 and have a narrow upper jaw, you may be able to join.
Konya, MeramAges 16–18

Common questions
- Are there clinical trials for maxillary expansion?
- Yes. Clin2 currently lists 16 recruiting maxillary expansion studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a maxillary expansion trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a maxillary expansion trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
