SECURE is an acrylic resin used as a permanent hard relining / pickup material for complete and partial dentures.

Not Found

The provided documents are a 510(k) clearance letter from the FDA for a device named "SECURE," which is an acrylic resin for relining dentures. This type of document typically does not contain detailed information about acceptance criteria or specific study designs, as it confirms substantial equivalence to a predicate device rather than de novo approval based on extensive clinical trial data.

Therefore, most of the requested information regarding acceptance criteria, study details, sample sizes, ground truth establishment, expert qualifications, adjudication methods, and MRMC/standalone studies is not available in the provided text.

Here's what can be extracted and what cannot:

1. A table of acceptance criteria and the reported device performance

• Not Available: The document does not specify performance metrics or acceptance criteria for the SECURE device nor does it report specific performance data from studies.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Not Available: The document does not describe any specific test set or studies that would involve sample sizes or data provenance.

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 Available: There is no mention of ground truth establishment or experts in the context of a test set.

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

• Not Available: No information on adjudication methods is present.

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/Not Available: This device is an acrylic resin for dentures, not an AI-powered diagnostic tool. Therefore, an MRMC study with human readers and AI assistance is not relevant to this device type, and no such study is mentioned.

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

• Not Applicable/Not Available: As explained above, this is a material, not an algorithm.

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

• Not Available: The document does not describe any studies that would involve establishing a ground truth for performance evaluation of the device.

8. The sample size for the training set

• Not Available: No information about a training set is provided.

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

• Not Available: No information about a training set or its ground truth establishment is provided.

Summary:

The provided FDA 510(k) clearance letter focuses on establishing substantial equivalence to a predicate device based on its intended use (as described in the "INDICATIONS FOR USE STATEMENT") and general safety and effectiveness. It does not contain the detailed study protocols, performance data, or statistical analysis that would typically be found in a clinical study report or a PMA submission for a novel device.
