What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This trial tests a new 3D printed dental appliance designed to correct an underdeveloped upper jaw in children aged 8-13 with class III malocclusion (where the lower jaw sticks out). The device, called a reverse twin block, is worn in the mouth to gently guide jaw growth over six months. Researchers will compare the 3D printed version to a conventional one to see if it improves jaw alignment, comfort, and oral health.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a 3D printed reverse twin block appliance
What this could lead to
If effective, this 3D printed device could offer a more precise and comfortable way to correct jaw alignment in growing children, potentially reducing the need for more invasive surgery later.
What could go wrong
This is a small, early-stage trial with only 30 participants, so results may not apply to everyone. The device is new and its long-term benefits or risks compared to standard care are not yet proven.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. The age group selected is mixed dentition group 8-13 years with residual potential maxillary growth. Patient maturity will be assessed using the Cervical Vertebral Maturation (CVM) method on lateral cephalogram, patients in CS1-CS3 stages will be included to ensure remaining maxillary growth. 2. Presence of permanent first molar with lower anterior teeth to retain the appliance. 3. Skeletal/dental class III tendency with anterior cross bite or reverse overjet: a. Clinically the overjet is equal or less than zero up to -3 mm. b. Cephalometric ANB angle equal or less than zero up to -3 degrees and Wits appraisal ≤ -2. 4. Prescence of unilateral or bilateral posterior crossbite. 5. Mild to moderate anterior crowding. 6. Acceptable oral hygiene baseline defined by oral hygiene index (OHI). - Exclusion Criteria: 1. Patients with cleft lip and palate and/or craniofacial anomalies. 2. History of previous orthopedic and/or orthodontic treatment. 3. Presence of uncontrolled systemic disease or medically compromised status. 4. Uncooperative patient/parents.
