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 This study
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 Results may not be published yet.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

Summary

This trial tests whether placing a temporary crown immediately after a dental implant helps keep gum tissue stable compared to placing the implant alone. About 44 adults with a non-restorable front tooth will be randomly assigned to one of the two approaches. Researchers will measure changes in gum shape and bone levels over time using digital scans and X-rays.

What this could mean

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

Active substance
dental implant placement with or without a temporary (provisional) crown
What this could lead to
If successful, this could help dentists choose the best approach for preserving gum tissue after tooth extraction and implant placement.
What could go wrong
This is a small, early-stage trial with only 44 participants, so results may not apply to everyone. Risks include implant failure, infection, or gum recession.

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 44 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

Aug 2028

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.

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

Inclusion Criteria: * Age ≥ 18 years * Physical status according to the American Society of Anesthesiology (ASA) I or II, which include patients who are systematically healthy or may suffer from mild to moderate, however well-controlled systemic diseases. * Periodontally healthy or with treated periodontitis with good oral hygiene ((FMPS) and (FMBS) ≤15%, measured at four sites per tooth). * Presence of one non-restorable maxillary anterior tooth (from #5 to #12 sites) * More than 20 occluding teeth with stable occlusion. * Nonsmokers or smokers \< 10 cig/day (self-reported). Exclusion Criteria: * Presence of uncontrolled or untreated periodontal disease. * Presence of active periapical infection. * Subjects taking medications known to modify bone metabolism or those that can interfere with the normal wound healing (such as bisphosphonates, corticosteroids, hormone replacement therapy, parathyroid hormone, denosumab, strontium ranelate, etc.), or those with uncontrolled systemic diseases or conditions that may similarly affect the patient's healing (osteoporosis, osteopenia, hyperparathyroidism, Paget's disease, uncontrolled diabetes (HBA1c \> 8)). * Pregnant subjects or individuals attempting to get pregnant (self-reported) * Subjects smoking 10 or more cigarettes a day, or those with a history of drug or alcohol abuse (self-reported) * Subjects unable to maintain adequate oral hygiene * Insufficient restorative space or bite collapse. * Lack of primary implant stability assessed intrasurgically.
