Cytoflex® Tef-Guard® Ti-Enforced membrane is a temporarily, non-resorbable, implantable material for use as a space-making barrier in the treatment of periodontal defects and augmentation of alveolar ridge in accordance with guided tissue regeneration principle.

Cytoflex® Tef-Guard® Ti-Enforced membranes are a multi-layer, non-resorbable membrane intended to be surgically placed under the muco-periosteum to aid in tissue regeneration in accordance with the guided tissue regeneration principle. It is a passive, non-load bearing material with a titanium frame enclosed within two exterior layers of ePTFE material. The titanium reinforcement is intended for space and shape maintenance to contain bone grafting material and to minimize graft migration during wound healing. The membranes are designed to reduce the migration and establishment of gingival tissue derived cells into bony defects thus providing a more favorable environment for neovascularization and bone derived cells to repopulate and repair the defect. The membranes are intended to be submerged and implanted for more than 30 days and up to 6 months. The membrane is supplied sterile and available in a variety of shapes and sizes for single use only.

Here's an analysis of the provided text regarding the acceptance criteria and study for the Cytoflex® Tef-Guard® Ti-Enforced Membrane:

Important Note: The provided document is a 510(k) Summary, which focuses on demonstrating substantial equivalence to a predicate device rather than comprehensive clinical efficacy testing. Therefore, many of the typical elements of a study proving a device meets acceptance criteria (like human reader studies, ground truth establishment for a test set, etc.) are not applicable in this context. The acceptance criteria here largely revolve around device performance characteristics and biocompatibility, demonstrated through non-clinical bench testing.

• Not Available. This information would be relevant for a study evaluating an AI/algorithmic device. The 510(k) summary for a physical device does not typically include "test datasets" in this context.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

• Not Applicable. Ground truth for data is not relevant for a physical barrier membrane in this type of submission.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not Applicable. See point 3.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• Not Applicable. This is a physical product, not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

• Not Applicable. This is a physical product, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• Not Applicable. Ground truth, in the context of AI/algorithmic devices, is not a concept applied to this type of physical medical device submission.

8. The sample size for the training set

• Not Applicable. No training set exists for this physical device.

9. How the ground truth for the training set was established

• Not Applicable. No training set or ground truth for a training set exists for this physical device.
