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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a new method called the Carrot Technique for rebuilding the jawbone before placing dental implants in the front upper teeth. It uses a small piece of the patient's own bone to widen the ridge, compared to the standard approach using artificial bone and a membrane. Twenty adults with missing teeth and moderate bone loss will be followed for one year to see which method works better.

What this could mean

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

Active substance
Carrot Technique (autogenous bone core) and Guided Bone Regeneration (bone substitute and collagen membrane)
What this could lead to
If successful, this could offer a simpler, effective method for rebuilding jawbone to support dental implants, potentially reducing the need for synthetic materials.
What could go wrong
This is a small, early-stage trial with only 20 participants, so results may not apply to everyone. The Carrot Technique is new and may not outperform standard methods.

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 20 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.

Inclusion Criteria: * Patients aged 18 to 45 years. Missing a single tooth in the maxillary esthetic zone requiring implant placement. Good oral hygiene and patient compliance. Medically free from systemic diseases that contraindicate implant surgery. Slight to moderate horizontal alveolar ridge deficiency with a minimum ridge width of 5 mm. Adequate vertical bone height for implant placement. Medium to hard bone quality (D2-D3 according to Misch classification). Absence of bruxism or other parafunctional habits. Exclusion Criteria: * Presence of local pathological lesions (e.g., cysts or tumors) at the planned surgical site. Poor bone quality (D4 bone). Pregnancy. Heavy smoking. Any medical condition contraindicating implant surgery.
