About this study

Official title: The "Open Wound Bone Augmentation Concept" with Amnion-Chorion Membrane: a Randomized Controlled Trial

The purpose of this study is to compare two bone graft wound healing techniques; an open wound healing approach versus the standard closed wound healing approach.

Read the detailed description

Open wound healing approach (experimental technique): the wound where the graft was attached to the bone will be filled with a type of tissue (the amnion-chorion membrane) taken from a placenta (the tissue sac that surrounds an embryo) and will be left partially open to heal.

Closed wound healing approach (standard technique): the wound where the graft was attached to the bone will be filled with collagen tissue (processed bone grafts from donors) and stitched closed while it heals.

20 patients needing more bone before placing a dental implant will be recruited for this trial. Patients will be randomized to either the test (open wound healing approach) or control (closed wound healing approach) group.

Being tested
Guided bone regeneration (GBR)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Guided bone regeneration (GBR)Procedure or surgery

    Also called Horizontal bone augmentation (HBA)

    Bone grafts will be placed in the patient's jawbone, along with a membrane to cover the bone grafts. A horizontal incision over the edentulous ridge crest will be made along with vertical incisions if indicated. Buccal and lingual full thickness mucoperiosteal flaps will be reflected to expose the alveolar bone. Intra-marrow penetration (decortication of the alveolar bone to increase vascular supply to the bone grafts) at the surgical site alveolar bone will be made with a high-speed hand piece and diamond bur. Bone allograft material will be placed to fill the alveolar bone defect. The bone graft will then be covered with a membrane and secured with sutures.

What is being measured

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

  1. Ridge width changes

    Radiographic changes of the ridge width based on cone-beam computed tomography (CBCT) scan measurements

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Guided bone regeneration (GBR) in people with Horizontal Ridge Deficiency, run by University of Michigan at 1 site in United States.

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 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: finished, as of the sponsor's last update on 25 Sep 2024. 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 United States. 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?

Ridge width changes (time frame: 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 NCT05013580, 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 25 Sep 2024.
