About this study

Official title: Clinical Evaluation of Different Alveolar Ridge Preservation Techniques After Tooth Extraction: a Single- Center, Triple Blinded Randomized Clinical Trial.

The aim of the present randomized controlled trial (RCT) was to evaluate the efficacy of different alveolar ridge preservation (ARP) techniques on hard tissue dimensional alterations after tooth extraction, based on clinical measurements.

Read the detailed description

Thrirty-six patients were randomly assigned in four treatment groups: A) freeze-dried bone allograft (FDBA) covered with collagen sponge (CS), B) FDBA covered with free gingival graft (FGG), C) demineralized bovine bone mineral xenograft (DBBM) covered with FGG and D) FGG without socket grafting. Clinical measurements were performed immediately after tooth extraction and 4 months later. The related outcomes pertained to both vertical and horizontal assessment of bone loss

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Vertical dimensional alterations of the alveolar ridge, after tooth extraction.

    Assessment of the alteration of the alveolar ridge height after different alveolar ridge preservation techniques, based on clinical measurements. Clinical measurements were carried out immediately after tooth extraction and 4 months later. Distances in those clinical measurements were recorded in 0.1 mm increments, using a digital calliper (Logilink digital caliper WZ0031).

    Measured: 4 months

  2. Horizontal dimensional alterations of the alveolar ridge, after tooth extraction.

    Assessment of the alteration of the alveolar ridge width after different alveolar ridge preservation techniques, based on clinical measurements. Clinical measurements were carried out immediately after tooth extraction and 4 months later. Distances in those clinical measurements were recorded in 0.1 mm increments, using a digital calliper (Logilink digital caliper WZ0031).

    Measured: 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Alveolar ridge preservation in people with Alveolar Bone Loss, run by National and Kapodistrian University of Athens at 1 site in Greece.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Vertical dimensional alterations of the alveolar ridge, after tooth extraction. (time frame: 4 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04934813, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jun 2021.
