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 Results may not be published yet.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

Summary

This study tested whether adding bone graft fibers instead of particles to a standard bone substitute leads to more new bone growth in the upper jaw. Twenty-six adults needing sinus augmentation before dental implants received both types of graft material. Researchers measured bone formation six months later using tissue samples and scans.

What this could mean

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

Active substance
Demineralized freeze-dried bone allograft (DFDBA) fibers and particles, combined with deproteinized bovine bone mineral (DBBM)
What this could lead to
If fibers work better, dentists may have a new option to improve bone growth for dental implants in the upper jaw.
What could go wrong
This is a small, completed study with only 26 participants, so results may not apply to everyone. The difference between fibers and particles might be small or not clinically meaningful.
