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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether using a surgical guide during sinus lifting—a procedure to add bone in the upper jaw for dental implants—improves outcomes compared to the conventional method. Thirty people with limited bone height (4-5 mm) will be randomly assigned to either guided or conventional sinus lifting using a piezoelectric device. The study measures implant stability, surgery time, pain, swelling, and complications like membrane perforation. If guided surgery works better, it could lead to more predictable and comfortable implant placement for people with atrophic maxilla.

What this could mean

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

Active substance
lateral sinus lifting with surgical guide (procedure)
What this could lead to
If guided sinus lifting proves better, it could make dental implants safer and more comfortable for people with limited bone in the upper jaw.
What could go wrong
This is a small, early-stage trial, so results may not apply to everyone. Surgery carries risks like membrane perforation, bleeding, or damage to nearby teeth.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
