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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested a special membrane placed in the tooth socket right after extraction to help preserve the jawbone shape. Forty adults who needed a tooth pulled were split into two groups: one got the membrane treatment, the other let the socket heal naturally. Researchers measured changes in bone width and height over four months to see if the membrane helped maintain the ridge for future dental work.

What this could mean

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

Active substance
d-ptfe membrane (a type of dental membrane)
What this could lead to
If successful, this technique could help preserve jawbone shape after tooth extraction, making future dental implants easier and more successful.
What could go wrong
This is a small, completed study with only 40 participants, so results may not apply to everyone. The technique may not significantly improve bone preservation over natural healing.

Show the full entry requirements

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

Inclusion Criteria: * At least 22 years of age * Systemically healthy * An extraction of one non-salvageable molar or premolar tooth is indicated. Adjacent teeth must be present to support the measuring template. * Demonstrated ability to maintain goodoral hygiene * Willingness and ability to commit to follow-up * Able to understand study procedure and provide signed informed consent. Exclusion Criteria: * Extensive damaged buccal or lingual bone plate * Extreme alveolar ridge atrophy * Extensive vertical bone loss * Active infection at the extraction site * Uncontrolled periodontal disease. * Recent febrile illness (within 6 months) that precludes or delays participation * Severe renal or liver diseases * History of radiotherapy of the head and neck region * Chemotherapy for treatment of malignant tumors at the time of the study. * Immuno-compromised patients * Patients on IV bisphosphonates or on long term oral bisphosphonates for more than 3 years. * Use of disallowed concomitant medications. * Pregnancy or intending to conceive during the course of the Study.
