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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers compare two bone grafting approaches for people with severe bone loss in the upper back jaw who need dental implants. Participants receive a sinus lift using osseodensification, a technique that gently compacts bone, followed by either allograft alone or a mix of the patient's own bone and xenograft. The study measures new bone height on scans and examines tiny bone samples taken during implant placement to see how much new bone forms.

What this could mean

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

Active substance
bone graft materials used during osseodensification sinus lift: allograft alone versus a mix of the patient's own bone and xenograft
What this could lead to
If one grafting approach builds bone more reliably, it could give dentists a clearer choice for placing implants in people with severe upper jaw bone loss.
What could go wrong
This is a small, single-center study of 24 people, so results may not apply broadly. Graft healing varies between patients, and the six-month follow-up may not capture long-term implant success.

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 24 people

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

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.

Eligibility Criteria Inclusion Criteria: Participants must: 1. Be 18-70 years old. 2. Have a severely atrophic posterior maxilla with RBH 0-4 mm confirmed by CBCT. 3. Have adequate bone width of minimum 7 mm. 4. Be in good health status and able to undergo surgery. 5. Provide informed consent and agree to follow study instructions. Exclusion Criteria: Patients with: 1. Uncontrolled systemic diseases, immunosuppression, history of head \& neck radiotherapy or chemotherapy. 2. Use of bisphosphonates, antiresorptive\*\*,\*\* or antiangiogenic drugs. 3. Pregnancy. 4. Heavy smoking (\>10 cigarettes/day). 5. Active sinus disease, oral infection, untreated periodontal disease, or severe bruxism. 6. Poor oral hygiene. 7. Anatomical issues such as sinus septa or inadequate ridge width preventing the OD approach. 8. Previous sinus lift or implant failure in the same site.
