Trial summary

An animal study and our pilot human study demonstrated that placing a smooth-surface titanium bone screw (TBS) over the buccal plate of an extraction socket resulted in less dimensional changes of the alveolar ridge along with no adverse effects. Read more about this study

About this study

Official title: Use of a Titanium Bone Screw for Ridge Preservation Following Tooth Extraction

An animal study and our pilot human study demonstrated that placing a smooth-surface titanium bone screw (TBS) over the buccal plate of an extraction socket resulted in less dimensional changes of the alveolar ridge along with no adverse effects. The purpose of this randomized clinical trial is to investigate the effectiveness of TBS application for ridge preservation in comparison to (1) unassisted/non-interventional socket healing and (2) alveolar ridge preservation (ARP) approach using allografts and a membrane.

Read the detailed description

The participants will be randomized to one of the three groups: the non-intervention, titanium bone screw (TBS), and alveolar ridge preservation (ARP) groups. The sockets in the non-intervention group will be filled with blood clots only. One TBS will be placed over the labial/buccal plate of the extraction socket in the TBS group on the same day of the extraction. Allograft and resorbable collagen membrane will be used for the ARP group.

Alveolar ridge preservation (ARP)Active comparatorThe extraction socket will be filled with mineralized ground cortical allograft up to the level of the buccal and lingual/palatal bony plates. A resorbable membrane will be trimmed and adapted to cover the grafting material. The flaps will be secured with a monofilament suture.
Receives: Other: Reducing dimensional changes following tooth extraction

What is being measured

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

  1. The width of the alveolar bone

Questions about this trial

What is this clinical trial studying?

A study testing Reducing dimensional changes following tooth extraction in people with Alveolar Bone Resorption and Tooth Extraction, run by University of Maryland, Baltimore.

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 3 inclusion and 6 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: withdrawn, as of the sponsor's last update on 24 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

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 was withdrawn before enrolling participants, so there are no results.

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?

The width of the alveolar bone (time frame: up to 6 months). 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 NCT05485194, which also lists 2 linked publications.

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 24 Jan 2025.
