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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study compares two ways of restoring dental implants: placing a temporary crown right away versus waiting three months. Researchers will track 50 adults over one year to see which approach leads to better implant survival and fewer complications. The goal is to find out if immediate restoration is a safe and effective option.

What this could mean

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

Active substance
dental implant (Lynx CONNECT) with immediate restoration or healing abutment
What this could lead to
If successful, this could show that immediate restoration is as safe and effective as waiting three months, potentially reducing treatment time for dental implants.
What could go wrong
This is a small, early-stage study with only 50 participants and a short 1-year follow-up. Results may not apply to all patients or implant types, and complications like implant failure or infection are possible.
