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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two surgical techniques to rebuild lost jawbone in the back of the lower jaw. One method uses the patient's own bone chips with a membrane, while the other uses a special plastic membrane. Sixteen adults with thin jawbones will be treated, and after six months, doctors will check how much new bone grew. The goal is to find which approach works better for 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
Khoury's bone shell technique and titanium-reinforced polytetrafluoroethylene membrane
What this could lead to
If successful, this could point to a better way to rebuild jawbone for dental implants, helping more people get stable teeth replacements.
What could go wrong
This is a very small early study with only 16 people, so results may not apply to everyone. The procedures are surgical and carry risks like infection or poor bone healing.

Study facts

What this study's own registry entry says, in plain language.

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

About 16 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jun 2025

Expected to finish

Mar 2027

An estimate. End dates often move.

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.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

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: 1. Have two or more missing teeth in the posterior mandibular segment. 2. The patients age of 18 and above. 3. The alveolar ridge in the edentulous site of the selected patients will have a buccolingual width of less than 4mm. 4. Sufficient vertical bone height. 5. Free of any local or systemic condition that may contraindicate ridge expansion procedure. Exclusion Criteria: 1. Patients taking any medication that may interfere with bone healing or bone biology. 2. Patients with any systemic disease that may affect bone healing. 3. Any patients with any previous bone grafting procedure at the site of interest. 4. Smokers. 5. Patient's that have been diagnosed with periodontal disease, as sufficient ridge height would be improbable. 6. Patients with significant vitamin D deficiency.
