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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 three ways to rebuild bone in the back of the lower jaw before placing dental implants. Seventy-eight adults will receive a graft made from their own bone, cow bone, or donated human bone. The main goal is to see which method adds the most width to the jawbone after 6 months, with follow-up up to a year.

What this could mean

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

Active substance
cortical shell bone graft (autogenous, xenogeneic, or allogeneic bone plates with bone chips and substitute)
What this could lead to
If successful, this could identify a reliable, less invasive bone grafting method for dental implants, reducing the need for harvesting the patient's own bone.
What could go wrong
This is a small, early-stage trial (78 people) comparing surgical techniques, not testing a new drug. Results may not apply to all patients, and complications like graft failure or infection are possible.

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 78 people

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

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Apr 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.

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: Posterior mandibular edentulism requiring horizontal ridge augmentation (Cawood \& Howell Classes IV-VI). One or two eligible posterior mandibular sites suitable for cortical shell augmentation. Adequate residual bone height to allow safe fixation above the mandibular canal. Good general health (ASA I or II). Plaque index \< 20% and absence of active periodontal infection. Ability and willingness to attend scheduled follow-up visits (up to 12 months). Written informed consent provided prior to any study-related procedure. Exclusion Criteria: Uncontrolled systemic diseases affecting bone healing (e.g., uncontrolled diabetes mellitus, immunosuppressive disorders). Current heavy smoking (\>5 cigarettes/day). Pregnancy or lactation. Current use of medications known to affect bone metabolism or healing (e.g., bisphosphonates, long-term corticosteroids, anticoagulants). Active periodontal disease or untreated oral infection. History of chemotherapy or radiotherapy to the head and neck region.
