What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looks back at 130 patients who had upper back teeth removed. Some had their tooth socket filled with bone graft material to preserve the jawbone, while others healed naturally. Researchers will compare CT scans taken months later to see if the preserved group has more bone height, potentially avoiding the need for a sinus lift procedure before placing dental implants.

What this could mean

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

Active substance
alveolar ridge preservation using bone graft material
What this could lead to
If successful, this could help dentists decide when to use bone preservation techniques to avoid more complex sinus surgeries for dental implants.
What could go wrong
This is a retrospective study looking at old records, not a controlled experiment. Results may not apply to all patients, and the findings are observational, not a proven treatment.

Who can take part

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

Who is studied

Patients who underwent extraction of posterior maxillary molars at the Saint Joseph University of Beirut's dental center, having underwent alveolar ridge preservation or not.

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * • Patients aged ≥18 years. * Patients who underwent alveolar ridge preservation after extraction of maxillary posterior teeth, as a test group. * Patients who underwent extraction of maxillary posterior teeth with unassisted socket healing without alveolar ridge preservation as a control group. Exclusion Criteria: * • The presence of a clinically symptomatic periapical radiolucency, acute abscesses, or chronic sinus tract, that may falsify the classification of posterior maxillary teeth on 2D radiographs.
