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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a modified surgical technique called periosteal inhibition to see if it helps maintain bone around dental implants placed right after tooth extraction. Thirty adults with a non-restorable back tooth and thin buccal bone will be randomly assigned to get either the new technique or the standard flapless implant procedure. The main goal is to measure bone changes using 3D X-rays over time.

What this could mean

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

Active substance
modified periosteal inhibition technique (a surgical procedure)
What this could lead to
If successful, this technique could help preserve bone around dental implants, potentially improving long-term implant success and reducing the need for additional bone grafts.
What could go wrong
This is a small, early-stage trial with only 30 participants, so results may not apply to everyone. The procedure is surgical, so risks include infection, pain, or implant failure.

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 30 people

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

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

Inclusion Criteria: * Patient's age ranges between 20 and 50 years including both genders. * General good health (American Society of Anesthesiologists I-II). * Presence of one hopeless non-restorable tooth requiring extraction at the posterior region. * Adequate amount of palatal bone and basal bone (≥ 3 mm) to engage the immediately placed implants. * Adequate keratinized soft tissue. * Thick gingival phenotype (˃ 1.5 mm). * Thin buccal bone plate or presence of fenestration. * Favorable pattern of occlusion. * Patient who is able to understand and sign a written consent. Exclusion Criteria: * Pregnancy or lactating females. * Untreated periodontitis. * Acute dentoalveolar infection. * Complete absence of buccal bone plate. * Osteometabolic disease. * Chemotherapy or radiation therapy history of the neck-head area within the past 12 months. * Heavy smokers (\>20 cigarettes/per day) according to WHO.
