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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 bone graft materials used to preserve jawbone after a tooth is pulled. One group gets a mix of human and animal bone graft, the other gets human bone graft alone. The goal is to see which better maintains bone shape for future dental implants. About 24 adults needing a tooth extraction and implant will take part over roughly two years.

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 (human bone substitute and animal bone substitute)
What this could lead to
If successful, this could show that mixing human and animal bone grafts preserves jawbone better than human bone alone, potentially improving dental implant outcomes.
What could go wrong
This is a small, early-stage study with only 24 participants, so results may not apply to everyone. Risks include typical surgical discomfort from tooth extraction and implant placement.

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 24 people

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

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 years and older

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. Provision of informed consent 2. At least 18 years old 3. In need of one posterior tooth (premolar or molar), excluding third molar molars, planned for extraction and replacement with a dental implant 4. Type I or II extraction socket/ ridge identified at the time of enrolment with cone-beam CT scan 5. At least one retained natural tooth adjacent to the study site Exclusion criteria 1. Insufficient interocclusal or interdental space to allow for an implant- supported prosthesis 2. Previous interventions performed involving soft and/or bone grafting in the study site 3. Active treated caries 4. Uncontrolled periodontal disease present 5. Evidence of active periapical, radicular, or endodontic lesions on teeth adjacent to study site 6. History of recent extraction of an adjacent tooth (mesial and distal) to study site within 6 months of enrollment 7. Current smoker with self-reported history of more than 10 cigarettes or equivalent per day 8. Self-reported use of smokeless tobacco or e-cigarette 9. Self-reported history of current alcohol or drug abuse 10. Systemic or local disease or condition that would compromise bone metabolism, post-operative healing and/or osseointegration e.g. uncontrolled diabetes with self-reported most recent HbA1c \> 8.0 within last six-month 11. Systemic corticosteroids or any other medication that would influence bone metabolism, post-operative healing, and/or osseointegration
