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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether 3D printed hybrid resin crowns look better than traditional milled crowns for single tooth implants. Thirty-two adults with healed implants will receive one type of crown and rate their satisfaction. Researchers will also check for complications like fractures over follow-up visits.

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 hybrid resin ceramic crowns
What this could lead to
If 3D printing proves better, it could offer a more esthetic and patient-friendly option for dental crowns.
What could go wrong
This is a small, early-stage trial with only 32 participants, so results may not apply widely. Crown fracture or other complications 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 32 people

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

Expected to start

Nov 2025

An estimate. Start dates often move.

Expected to finish

Nov 2026

An estimate. End dates often move.

Lead sponsor

A research network

The lead sponsor is a research network or cooperative group.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 70 years

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: * Age: between 18 and 70 years old at the time of screening. * Patients with implants placed and in need for crown restoration * Medically free with no systemic diseases. * Good oral hygiene with no active periodontal disease. * Patient's having adequate interocclusal and mesiodistal restorative space for the fabrication of a single implant-supported crown. * Patients willing and able to provide written informed consent for participation in the study, understanding its risks, benefits, and alternative treatments. Exclusion Criteria: * Uncontrolled systemic diseases (e.g., uncontrolled diabetes, severe cardiovascular disease, active autoimmune disorders, uncontrolled thyroid dysfunction). * Patients with composite restoration on the labial/buccal surface implant's neighbouring. * Immunocompromised patients or those undergoing immunosuppressive therapy. * Patients undergoing radiation therapy to the head and neck region, or chemotherapy. * Patients currently on or with a history of medications known to significantly affect bone metabolism (e.g., long-term bisphosphonates, corticosteroids). * Pregnancy or lactation. * Known allergies to titanium, resin components, or any other materials used in the study (e.g., composite, zirconia).
