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 This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

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 Results may not be published yet.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.

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 trial compares two techniques for placing temporary anchorage devices (TADs) in the jawbone to support orthodontic treatment. Healthy adults needing premolar extractions and maximum anchorage will receive both insertion methods on opposite sides of the mouth. The study measures which technique leads to better TAD survival, stability, and patient comfort over six months.

What this could mean

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

Active substance
Temporary Anchorage Device (TAD) inserted via steady oblique-angled or two-step angulation technique
What this could lead to
If one technique proves superior, it could improve the success and comfort of orthodontic treatments that require temporary anchorage devices.
What could go wrong
This is a small, early-stage trial with only 28 participants, so results may not apply to all patients. The techniques are already in use, so the benefit may be modest.

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 28 people
