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
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 Results may not be published yet.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 compares the accuracy of two different intraoral scanners (MEDIT i600 and Aoralscan) against a standard laboratory scanner when digitizing impressions of the lower jaw in people with no teeth. Participants will have impressions taken and then scanned with each device to see which one most closely matches the reference scan. The goal is to find out if these handheld scanners can reliably capture the tricky contours of an edentulous arch, which could improve the fit of dentures.

What this could mean

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

Active substance
Digital impression using intraoral scanners (MEDIT i600 and Aoralscan) compared to an extraoral scanner
What this could lead to
If one scanner proves more accurate, it could guide dentists in choosing the best digital tool for fitting dentures, potentially improving comfort and fit for people with no teeth.
What could go wrong
This is a small study with only 9 participants, so results may not apply to everyone. The accuracy of scans can also vary with patient anatomy and operator skill.

Study facts

What this study's own registry entry says, in plain language.

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.

An estimate. Start dates often move.

Expected to finish

Oct 2026

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
