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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether all-ceramic dental bridges hold up as well as traditional metal-ceramic ones. The trial enrolls adults missing at least three back teeth who need a bridge. Participants receive either a zirconia ceramic bridge or a metal-ceramic bridge, and the study tracks fractures, chipping, and wear over time. The goal is to understand how material thickness, connector size, and bite force affect bridge survival, so dentists can build more durable replacements.

What this could mean

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

Active substance
Zirconia ceramic dental bridge (all-ceramic) compared to a metal-ceramic dental bridge
What this could lead to
If it works, this could point toward stronger, longer-lasting all-ceramic dental bridges that resist fracture and wear better than current options.
What could go wrong
This is a mid-sized trial, and results may not apply to all patients. Bridges can still fracture or chip depending on individual bite forces and material limits.
