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 Results may not be published yet.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.

Summary

This study looks at two types of short dental implants (6 mm) placed in the front upper jaw to see how bone and gum tissue change over time. Twenty adults with missing teeth in the esthetic zone will receive implants with either a converging collar with micro threads or a diverging polished collar. Researchers will measure bone height, soft tissue changes, and success rates using X-rays and 3D scans.

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 with converging collar with micro threads or diverging polished collar
What this could lead to
If successful, this could help dentists choose the best implant design to maintain bone and gum health around short implants in the front upper jaw.
What could go wrong
This is a small, early-stage trial with only 20 participants, so results may not apply to everyone. The study is observational in nature and does not test a new treatment.
