    Intended Use

    OpenTex is a temporarily implantable material (non-resorbable) for as a space-making barrier in the treatment of periodontal defects.

    Device Description

    OpenTex is a non-resorbable PTFE membrane composed of proprietary 100% polytetrafluoroethylene (PTFE) sheet with inert biological features and predictable barrier effect. OpenTex is designed to function as a physical barrier to avoid gingival cell invasion, thus providing a favorable environment for neovascularization and bone derived cells to repopulate and repair the defect. Since space-making is critical to this procedure, the membrane is sufficiently stiff to prevent spontaneous collapse but supple enough to conform easily to tissue contours. OpenTex is supplied sterile and intended for single use only. It is available in various sizes.

    AI/ML Overview

    This is a 510(k) summary for a medical device called OpenTex, a non-resorbable PTFE membrane for guided tissue regeneration in periodontal defects. The information provided is for regulatory clearance and does not involve AI or algorithms with human-in-the-loop performance. Therefore, many of the requested fields are not applicable.

    Here's an analysis of the provided text based on your request:

    2. Sample size used for the test set and the data provenance

    The document describes non-clinical bench testing comparing the physical and chemical properties of OpenTex to its predicate device. This type of testing typically uses a small number of samples (often 3-5 per test) to evaluate material properties under controlled laboratory conditions, rather than a "test set" in the context of AI or clinical trials. The specific sample sizes for each test are not explicitly provided in the document.

    The data provenance is from laboratory testing performed by the manufacturer, Purgo Biologics Inc. The country of origin for the data is implicitly South Korea, where the company is located. The data is non-clinical performance data.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    This question is not applicable as the document describes bench testing of physical and chemical properties, not a clinical study involving human reads or expert ground truth establishment for diagnostic purposes. The "ground truth" here is the adherence to established international standards and internal criteria for material performance.

    4. Adjudication method for the test set

    This question is not applicable as there is no clinical test set requiring adjudication by experts.

    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

    This question is not applicable. The device is a physical bone grafting material (membrane), not an AI-assisted diagnostic or therapeutic tool. No MRMC study was performed.

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

    This question is not applicable. The device is a physical medical device, not an algorithm.

    7. The type of ground truth used

    The "ground truth" for the performance tests is based on established international standards (e.g., ASTM D882, ISO 6383-1, ANSI/AAMI/ISO 7198, ISO 10993 series, ISO 11135) and internal criteria set by the manufacturer to demonstrate substantial equivalence to the predicate device.

    8. The sample size for the training set

    This question is not applicable. There is no "training set" as this is a physical medical device for which performance is evaluated through non-clinical testing, not a machine learning model.

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

    This question is not applicable for the same reasons as #8.
