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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a custom 3D printed marker can help dentists place a single front tooth implant more accurately. Ten people with a missing front tooth will get a 3D printed marker made from their scans, which guides the dentist during surgery. After the implant, a CT scan checks how close the actual placement matches the plan. The goal is to see if this method is precise enough for everyday use.

What this could mean

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

Active substance
3D printed custom registration marker
What this could lead to
If successful, this could offer a more accurate and reproducible way to place dental implants in the front upper jaw, potentially improving cosmetic outcomes.
What could go wrong
This is a very small early study with only 10 participants, so results may not apply to everyone. The marker's accuracy depends on the quality of scans and may not work for all jaw shapes.

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 10 people

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

Started

Aug 2025

Expected to finish

Oct 2025

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

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Single missing tooth in the anterior maxilla * ≥12 mm bone height and ≥5.5 mm width * D3 bone density * Angle's Class I occlusion * No systemic contraindications to implant surgery Exclusion Criteria: * Heavy smoking or uncontrolled diabetes * Radiation therapy involving the head and neck * Parafunctional habits (e.g., bruxism) * Class III malocclusion or edge-to-edge bites
