About this study
The purpose of the study is to compare a new grafting material for alveolar ridge preservation to a commonly used and well studied material. Alveolar ridge dimensions as well as histology will be compared.
Read the detailed description
Brief Background and Goal: Dimensional changes following extractions are inevitable. Many techniques and combinations of materials have been studied and shown to be effective at minimizing these changes. Although no material has been able to fully preserve the ridge, xenografts have been shown to be the most effective at maintaining the volume, however, the use of demineralized freeze-dried bone allograft (DFDBA) results in the most vital bone when evaluated histologically. These factors are important when planning for a successful future implant supported prosthesis. A new material that combines xenograft (deproteinized bovine bone mineral - DBBM) with DFDBA has recently been introduced to the market. The aim of the study is to compare the dimensional and histological changes following flapless alveolar ridge preservation (ARP) in the premolar and molar region with a new material that combines DFDBA and DBBM to a commonly used mineralized allograft.
Research Question: In patients who require an extraction for future implant placement, during alveolar ridge preservation, will combining demineralized freeze-dried bone allograft (DFDBA) and deproteinized bovine bone mineral (DBBM) compared to Tutoplast® processed mineralized particulate allograft result in less dimensional changes at the time of implant placement 4 months later.
Specific Aims: The primary goal of the study is to compare the dimensional changes following alveolar ridge preservation with a new material that combines DFDBA and DBBM to a commonly used mineralized allograft material. The secondary goal is to assess the histological composition of the bone after 4 months of healing. The additional goals are to measure possible confounding factors on the dimensional changes of the alveolar ridge.
Significance: The goal behind the combination of DBBM and DFDBA is to evaluate whether there could potentially be a synergistic effect between the two materials that would make it a more desirable material to use for ARP procedures.
Innovation: There is currently no published research that compares the combination of DFDBA and DBBM to a conventional method inside the extraction site during an alveolar ridge preservation procedure. This grafting material is new on the market and the first of its kind.
Research Plan: The randomized clinical trial will be performed at the Nova Southeastern College of Dental Medicine in the Post-graduate Periodontology Clinic. 30 patients requiring premolar or molar extraction with future implant placement will be randomly divided into 2 groups, one test and one control. Following extraction, the patients will receive either allograft or graft combination of DFDBA and DBBM. The changes in horizontal and vertical dimensions of the alveolar ridge as well as the histology will be assessed and compared at 4 months.
Expected Results: When compared to allograft, the graft mixture containing the DFDBA and DBBM will maintain greater dimensional volume due to the dimensionally stable properties of DBBM and will contain more vital bone due to the osteoinductive properties of DFDBA.

Questions about this trial
What is this clinical trial studying?
A study testing Alveolar ridge preservation in people with Alveolar Ridge Preservation and Dental Extraction, run by Nova Southeastern University 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 6 inclusion and 9 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: looking for participants now, as of the sponsor's last update on 12 Sep 2025. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Andee Goldstein, DMD (7542599445, ag3577@mynsu.nova.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
changes in horizontal dimensions of the alveolar ridge (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 NCT06275789, which also lists 45 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 12 Sep 2025; AzTrials last refreshed its copy on 8 Nov 2026.
