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 Results may not be published yet.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

Summary

This study compares two ways of making metal frameworks for partial dentures in the lower jaw: one using digital design and manufacturing (CAD/CAM), and the other using traditional methods. The goal is to see which approach better supports the health of the teeth that hold the denture (abutment teeth) and improves how the teeth fit together when biting. The trial will involve 22 adults with a specific type of missing teeth (Kennedy class III) and will measure tooth mobility and gum bleeding.

What this could mean

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

Active substance
CAD/CAM metallic partial denture framework
What this could lead to
If successful, this could show that digitally made denture frameworks are better for tooth and gum health than traditional ones.
What could go wrong
This is a small, early-stage study with only 22 participants, so results may not apply to everyone. It compares two methods but doesn't test a new treatment.

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 22 people

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

Expected to start

Oct 2025

An estimate. Start dates often move.

Expected to finish

Jan 2026

An estimate. End dates often move.

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.

Ages
