Ridge Preservation Comparing a PTFE Nonresorbable Membrane to a Collagen Membrane
A study testing PTFE membrane and Collagen membrane in people with Clinical Efficacy, run by University of Louisville at 1 site in United States.
Trial summary
A non-resorbable PTFE (teflon) membrane will be compared to a resorbable collagen membrane when used for a post-extraction ridge preservation procedure to prevent the bone loss that typically occurs. The hypothesis is that there will be no difference in the clinical and histologic results between the two membranes. Read more about this study

About this study
Official title: Ridge Preservation Comparing the Clinical and Histologic Healing of a PTFE Non-resorbable vs. a Collagen Membrane With an Intrasocket Mineralized Cancellous Allograft Plus a Facial Overlay Bovine Xenograft.
A non-resorbable PTFE (teflon) membrane will be compared to a resorbable collagen membrane when used for a post-extraction ridge preservation procedure to prevent the bone loss that typically occurs. The hypothesis is that there will be no difference in the clinical and histologic results between the two membranes.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PTFE membraneProcedure or surgery
The non-resorbable PTFE barrier membrane will be surgically placed in conjunction with a ridge preservation procedure.
Collagen membraneProcedure or surgery
A resorbable collagen membrane is surgically placed in conjunction with a ridge preservation procedure.
| Study group | Role | What they receive |
|---|---|---|
| PTFE membrane | Active comparator | A non-resorbable PTFE (polytetrafluoroethylene) membrane will be used as a positive control treatment. Receives: Procedure: PTFE membrane |
| Collagen membrane | Experimental | A resorbable collagen membrane will be used in the test group. Receives: Procedure: Collagen membrane |
What is being measured
The primary outcome is the main question the study is designed to answer.
Crestal ridge width
The crestal ridge width will be measured with a digital caliper at the baseline exam and at the 4 month examination.
Measured: Time 4 months
Secondary outcomes (1)
Percent vital bone
A trephine core will be taken at 4 months immediately prior to implant placement from the implant osteotomy site.
Measured: Time 4 months

Questions about this trial
What is this clinical trial studying?
A study testing PTFE membrane and Collagen membrane in people with Clinical Efficacy, run by University of Louisville 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 10 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 8 Dec 2016. 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?
Crestal ridge width (time frame: Time 4 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 8 Dec 2016.
