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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether digital scanning methods or the traditional mold approach produce a better fit for full-arch dental implants in people with no teeth. Eight patients will receive four lower-jaw implants, and each will try all three impression techniques. The fit of the resulting frameworks will be checked with a clinical test and X-rays to see which method is most accurate.

What this could mean

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

Active substance
Comparison of three dental impression techniques: IO-Connect digital impression, Reverse Scan Body digital impression, and conventional splinted open-tray impression.
What this could lead to
If one impression method proves superior, it could lead to more accurate and longer-lasting dental implant frameworks, reducing complications and improving patient comfort.
What could go wrong
This is a small, early-stage study with only 8 participants, so results may not apply broadly. The techniques may show no significant differences, and individual patient variations could affect outcomes.

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 8 people

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

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.
