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 Results may not be published yet.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.

Summary

This study tests whether directly 3D-printed clear aligners work better than traditional thermoformed ones for mild teeth crowding or spacing. About 34 adults aged 15-30 will wear the aligners for 22 hours a day, changing them weekly. Researchers will compare how accurately the teeth move and how satisfied patients are.

What this could mean

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

Active substance
Direct-printed aligner (Clear-A V2 resin) and thermoformed aligner (Zendura FLX)
What this could lead to
If direct-printed aligners work better, they could offer a faster, more accurate way to straighten teeth without needing molds.
What could go wrong
This is a small, early-stage trial with only 34 people. Results may not apply to everyone, and the new printing method might not be more effective than the standard one.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 34 people

The number the study aims to enrol. It can still change while the study runs.

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. Adult patient with an age range of 15-30 with fully erupted all permanent dentitions excluding third molars, and a willingness to participate in the trial. 2. Angle Class I non-extraction cases, presented with mild crowding or spacing (\<5 mm) and dental rotation \<30° . 3. Good oral hygiene; no active caries/periodontal disease, no history of trauma or root resorption. Exclusion Criteria: 1. Pregnancy, smoking, and systemic conditions affecting bone remodeling. 2. Subject with poor oral hygiene, using simplified oral hygiene index (OHI-S ≥ 3.1 ) (Greene \& Vermillion, 1963). 3. Patient with malposed lower second molars (need orthodontic alignment). 4. Allergy to materials used (resins, plastics, solvents). 5. History of trauma, root resorption, and dilacerated roots. 6. Previous extraction or history of previous orthodontic treatment.
