What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial compares three orthodontic techniques for pulling the upper front teeth backward in adults with Class II malocclusion. All methods use small temporary screws for anchorage, but they differ in bracket design and archwire setup. The goal is to see which approach causes the least root shortening, a common side effect of braces. Sixty adults will be randomly assigned to one of the three methods, and X-rays will track root length changes over time.

What this could mean

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

Active substance
Three orthodontic retraction techniques: bidimensional bracket system, hybrid dual-section archwire, and conventional sliding mechanics, all using miniscrew anchorage.
What this could lead to
If one method proves gentler on tooth roots, it could guide orthodontists toward safer treatment choices, reducing the risk of permanent root shortening for patients.
What could go wrong
This is a small, early-stage trial, and results may not apply to all patients. Root resorption is measured on X-rays, which may not capture the full picture, and individual variation is high.

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

Inclusion Criteria: * Adults aged 18-30 years. * Class II Division 1 dental malocclusion according to Angle classification * Mild-to-moderate skeletal Class II discrepancy, with an ANB angle greater than 4° and not exceeding 7°. * Overjet ranging from 5 to 9 mm. * Presence of all six maxillary anterior teeth. * Maxillary anterior teeth fully erupted and with complete root formation. Exclusion Criteria: * Patients with previous orthodontic treatment. * Missing permanent maxillary teeth. * Active periodontal disease. * History of trauma to any maxillary anterior tooth. * Previous endodontic treatment of any maxillary anterior tooth. * Periapical pathology involving any maxillary anterior tooth. * Extensive coronal restorations that could interfere with crown-length measurement. * Radiographic evidence of pre-existing root resorption before orthodontic treatment.
