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

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 Results may not be published yet.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.

The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This small pilot study looked at 8 adults who needed a single tooth replaced with an immediate dental implant. Researchers compared two methods to manage the gap between the implant and the cheek bone: a bone mineral graft or a soft tissue graft. They used scans and X-rays to measure bone and gum changes over 6 months. The goal was to see which method better preserves the bone and gum around the implant.

What this could mean

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

What could go wrong
This is a very small pilot study with only 8 participants, so results may not apply to everyone. It is too early to draw firm conclusions.

This is an AI summary of the original study and may miss details. Read our disclaimer.
