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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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 tested a special drilling technique called osseodensification, which compresses bone instead of removing it, to prepare the jaw for dental implants. Twenty-three adults with missing teeth received about 40 implants using this method. The goal was to see if the technique could expand the bone enough to place implants without extra grafting. Early results suggest it may work, but larger and longer studies are needed.

What this could mean

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

Active substance
Densah burs (a special dental drill that compresses bone rather than removing it)
What this could lead to
If this technique works well, it could allow more people to get dental implants without needing a separate bone graft procedure.
What could go wrong
This was a small, early study with only 23 participants and no comparison group. The results may not apply to everyone, and long-term implant success is still being checked.
