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 This study
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 Results may not be published yet.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

Summary

This study tests a new way to lift the sinus floor using a special drill (Densah bur) guided by a surgical template, while placing a dental implant at the same time. Ten patients with missing upper back teeth and a shallow sinus will receive this procedure. The goal is to see how much bone can be added and how well the implant holds.

What this could mean

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

Active substance
densah drill technique
What this could lead to
If successful, this technique may offer a more precise and less invasive way to lift the sinus floor and place dental implants in one procedure.
What could go wrong
This is a very small early study with only 10 patients, so results may not apply to everyone. Risks include pain, infection, or implant failure.
