Comparative Volumetric Assessment of Alveolar Ridge Preservation Utilizing Different Bone Grafting Materials

December 6, 2019 updated by: University of North Carolina, Chapel Hill

Prospective, Comparative Volumetric Assessment of Alveolar Ridge Preservation Utilizing Different Bone Grafting Materials (SYMBIOS CORTICAL-CANCELLOUS GRANULE MIX; SYMBIOS OSTEOGRAF LD-300; OSTEOGRAF/N-300) Following Tooth Extraction

This study is intended to provide statistically robust evidence that Symbios Demineralized Cortical-cancellous granule mix, Symbios OsteoGraf LD-300, and OsteoGraf/N-300 combined with Symbios OsteoShield Collagen Resorbable Membrane can adequately support the alveolus during ridge augmentation procedures, reducing the dimensional changes of both the alveolus and the overlying soft tissues. Additionally, a comparison between each material will be made, providing further evidence of each materials' ability to preserve the alveolus. It is intended to define in objective terms the response of the hard and soft tissues to ridge augmentation.

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.

Ages Eligible for Study

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
Total Mean Change in Bone Volume
Time Frame: time of extraction to 3 months post extraction
The change in bone volume at 3 months following extraction will be calculated using data from DICOM images acquired by Cone Beam Computed Tomography (CBCT) using 3D software
time of extraction to 3 months post extraction

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
Mean Osseous Dimensional Changes-Horizontal
Time Frame: time of extraction to 3 months post extraction
The amount of linear (mm) horizontal bone change at 3 months following tooth extraction at a position located 2mm and 4mm vertically away from the height of the buccal plate. Data will be calculated using data from DICOM images acquired by CBCT using 3D software.

Mean Osseous Dimensional Changes-Vertical
Time Frame: time of extraction to 3 months post extraction
The amount of linear (mm) vertical bone change at 3 months following tooth extraction at a position located mid-buccal, mid-palatal, mesial and distal of the extraction site. Data will be calculated using data from DICOM images acquired by CBCT using 3D software.
