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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 two ways to repair bone and gum defects during immediate dental implant placement. One group gets a standard collagen membrane, the other a connective tissue graft from the palate. Researchers want to see if the graft works just as well for bone healing while improving gum thickness and appearance. Twenty-four adults with a failing front tooth will be followed for 12 months.

What this could mean

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

Active substance
connective tissue graft and deproteinized bovine bone mineral with collagen (DBBM-C)
What this could lead to
If successful, this could offer a better way to restore bone and gum tissue around dental implants, improving both function and appearance.
What could go wrong
This is a small, early-stage study with only 24 participants, so results may not apply to everyone. Surgical risks like swelling 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 24 people

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

Expected to start

Apr 2026

An estimate. Start dates often move.

Expected to finish

Jul 2029

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.

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

Inclusion Criteria: * • Adult patients with ⩾ 25 years of age. * Ability to understand all the study procedures and to comply with them along the entire study period. Ability and willingness to give written informed consent. * Periodontal health in an intact or reduced periodontium (2017 World Workshop in Periodontal and Peri-implant Diseases and Conditions) (G. Caton et al., 2018). * Good level of oral hygiene (Plaque Index \< 20%) (Löe, 1967). * Failing tooth in the anterior area of the maxillary arch (incisors, canines and premolars). * Bone availability for a prosthetically driven single-unit immediate implant. * A peri-implant BBD with a minimum vertical dimension height (VDH) of 3mm, detected by means of a CT imaging. * Presence of adjacent teeth. * Presence of antagonist teeth. * Keratinized mucosa of at least 2mm on the buccal aspect of the tooth to be extracted. Exclusion Criteria: * Smokers ⩾ 10 cigarettes per day. * Pregnant women or lactating females. * Acute periapical infection. * Presence of buccal/palatal and/or interproximal gingival recession in the target tooth. * Any systemic disease or medication that contraindicates implant treatment or could influence the outcome of the therapy (i.e., non-controlled diabetes mellitus, osteoporosis, radiotherapy, bisphosphonate medication, ...). * Long-term non-steroidal anti-inflammatory drug therapy (⩾ 3 months). * Lack of primary manual stability of the implant during installation.
