Ridge Preservation Comparing 2 Membranes

December 6, 2016 updated by: Henry Greenwell, University of Louisville

Ridge Preservation Comparing the Clinical and Histologic Healing of a PTFE Non-resorbable Membrane Versus an Acellular Dermal Matrix Allograft Plus a Facial Overaly Bovine Xenograft.

The purpose of this study is to compare the clinical and histologic outcomes for acellular dermal matrix and a nonresorbable membrane to determine if either provides a significant therapeutic advantage. The hypothesis is that there will be no difference in crestal ridge width between the two treatments.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

  2. Healthy male or female who is at least 18 years old.
  3. Patients must sign an informed consent approved by the University of Louisville Human Studies Committee.

Exclusion Criteria

  1. Patients with debilitating systemic diseases, or diseases that have a clinically significant effect on the periodontium.
  2. Presence or history of osteonecrosis of jaws.
  3. Patients who are currently taking IV bisphosphonates or who had IV treatment with bisphosphonates irrespective of duration.
  4. Patients who have been treated with oral bisphosphonates for more than three years.
  5. Patients with an allergy to any material or medication used in the study.
  6. Patients who need prophylactic antibiotics.
  7. Previous head and neck radiation therapy.
  8. Chemotherapy in the previous 12 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Crestal ridge width
Time Frame: 4 months
The width of the ridge at the crest will be measured with a digital caliper.
4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percent vital bone
Time Frame: 4 months
Percent vital bone at the graft site will be determined from a trephine core sample.
4 months

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
