Recruiting studies
- NCT07773389Recruiting
Early vs late premolar removal for braces
This study compares removing two back teeth early versus later during braces treatment to see which timing leads to better tooth movement. It may help teens and young adults needing braces for crowded teeth or overbite.
IslamabadAges 13–25 - NCT05684510Recruiting
Clear aligners vs braces for mild overbite in adults
This trial compares clear plastic aligners with fixed braces to improve mild overbite (Class II) in adults who have not had orthodontics before. It may help you understand which option works better for your bite and alignment while also checking fit and dental health needs.
Hama, Hama GovernorateAges 15–20 - NCT05950581Recruiting
Twin-block braces with clear plates for jaw misalignment
This study tests a removable orthodontic device (twin-block with clear plates) to improve how the upper and lower jaws fit together in children. It may help if you have a specific “Class II” jaw pattern caused mainly by a lower jaw that sits back.
HamaAges 10–13 - NCT06602518Recruiting
Airway changes after braces for deep overbite
This study looks at how fixing a deep overbite (where top teeth cover most of your bottom teeth) with braces may affect the size of your airway (the space in the back of your throat for breathing). It helps doctors understand if treatment can also help with breathing.
AlexandriaAges 12–16 - NCT07162753Recruiting
Ethnic bias check in AI orthodontic diagnosis
This trial checks if an AI system for orthodontic diagnosis works equally well for people of different ethnic backgrounds. You may be eligible if you have a side-view face photo taken before braces or similar treatment.
Istanbul, FatihAges 4 years+ - NCT07340242Recruiting
3D-Printed Braces vs. MARA for jaw alignment
This trial compares two types of braces (a 3D-printed removable brace and a fixed brace called MARA) to see which works better for correcting a bite problem where the lower jaw is too far back. It is designed for teenagers who are still growing and have a large overbite.
Al Mansurah, Dakahlia GovernorateAges 9–14 - NCT07676695Recruiting
Jaw Device and Sound Waves for Class II Malocclusion
This trial tests a special jaw repositioning device (Twin-Block) combined with low-intensity sound waves (LIPUS) to help treat a class II malocclusion (when the lower jaw is set back) in children and teens. It aims to improve jaw alignment and joint outcomes.
CairoAges 10 months–1.2 years - NCT07405905Recruiting
Comparing mini implant placements for fixing upper teeth overbite
This study tests two ways of placing small temporary anchors (mini implants) in the jaw to help pull upper front teeth back into a better position. It is for patients who have finished growing and have a Class II overbite, to see which anchor location works best.
Rohtak, HaryanaAges 18–30 - NCT07466641Recruiting
Low-level laser or Piezocision to speed up canine tooth movement
This trial compares two treatments to see if they can safely speed up a specific tooth movement during braces. It tests a low-level laser or a minor surgical procedure called Piezocision against standard care.
Cairo, Cairo GovernorateAges 18–25 - NCT06984666Enrolling by invitation
Study of facial profiles at 45 degrees
This study looks at facial features from a 45-degree angle to see what makes a beautiful profile. It includes orthodontists, patients who have had braces for over a year, and adults without braces experience. You will have photos taken and answer some questions.
Fuzhou, FujianAges 18–50 - NCT07307209Recruiting
Comparing two ways to move upper teeth backward with tiny screws
This trial compares two methods (sliding jigs vs retraction hooks) to move your upper teeth backward using small screws placed in your jawbone. It may help if you have a mild overbite or crowded upper teeth and want to avoid removing teeth.
SanaaAges 14 years+ - NCT06511219Recruiting
Moving upper back teeth with a 3D-printed brace
This study tests a new 3D-printed dental device to move the upper back teeth backward in teenagers with an overjet (bucked teeth) and a class II bite. It may help correct the bite without removing teeth or using headgear.
Al MansurahAges 13–18 - NCT06651944Recruiting
Invisalign with jaw advancement aligners
This trial tests Invisalign clear aligners that also help move the lower jaw forward. It may be a good fit if you need both teeth straightening and jaw positioning help.
Richmond, British ColumbiaAges 10–16 - NCT06944860Recruiting
3D-printed vs. traditional twin block braces for kids
This trial compares a new 3D-printed twin block brace to a traditional one for children with a large overbite (overjet ≥7 mm). It checks how well germs stick, how smooth the brace is, and how well it works—plus how children feel about it.
Kuala Lumpur, Kuala LumpurAges 10–14 - NCT07040176Recruiting
Moving upper back teeth back with aligners or mini-screws
This study compares two ways to move the upper back molars backward to fix an overbite where the upper teeth stick out too far. One method uses clear aligners, the other uses tiny temporary screws in the jawbone.
ThessalonikiAges Up to 30 years - NCT07361172Recruiting
Ready-made vs custom-made braces for jaw correction
This trial compares two types of orthodontic appliances to correct a Class II bite (where the upper teeth sit too far forward). It tests whether a custom-made device works better than a ready-made one for teens.
Al Mansurah, AdakhliaAges 12–16 - NCT07752498Enrolling by invitation
Long-term results from twin block treatment
This study checks whether the results from an earlier treatment with the Twin Block appliance, which corrects bite problems, hold up over time. It looks at how stable the teeth and jaw remain years after treatment.
Jönköping, Jönköping CountyAges Any age - NCT06976749Enrolling by invitation
Jaw appliances for overbite and airway in teens
This trial compares two dental appliances—Twin Block and Myobrace—to see which one better improves your airway and facial shape during the teenage growth spurt. If you have a set-back lower jaw and moderate overbite, participating could help guide your jaw growth and breathing.
