The provided 510(k) clearance letter and summary describe a medical device, Medentika CAD/CAM Abutments, and its substantial equivalence to predicate devices based on non-clinical performance data. The document does not contain information about acceptance criteria or performance data for an AI/ML-based device, nor does it detail a clinical study involving human readers or expert consensus for ground truth.

Therefore, for the information requested in your prompt, I can only extract what is presented in the document, which pertains to the non-AI aspects of device acceptance and testing. Many of the points specifically refer to AI/MRMC studies, which are not applicable to this document.

Here's an analysis based on the provided text:

Device Description and Purpose:
The device is "Medentika CAD/CAM Abutments," which are dental implant abutments. The primary purpose of this submission is to expand the fabrication options for patient-specific final abutments from a "validated milling center" to a "digital dentistry workflow" that integrates CAD/CAM software and milling machines. It also adds new sizes and OEM compatibilities.

Study Type:
This is a pre-market notification (510(k)) submission seeking substantial equivalence to existing legally marketed devices. It relies heavily on non-clinical performance data to demonstrate that the new manufacturing workflow and expanded compatibilities do not raise new questions of safety or effectiveness.

Analysis of Requested Information (based on the provided document):

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

The document outlines various performance tests conducted to demonstrate substantial equivalence, but it does not explicitly present a "table of acceptance criteria" with corresponding "reported device performance." Instead, it states that the tests demonstrate sufficient strength or ensure accuracy and reliability.

Here's a summary of the performance tests and their implied purpose:

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

• Sample Size for Test Set: The document does not specify numerical sample sizes for any of the non-clinical tests (e.g., how many abutments were mechanically tested, how many software validation tests were run). It simply states that "testing was conducted" or "validation was performed."
• Data Provenance: The document does not explicitly state the country of origin of the data or whether the studies were retrospective or prospective. Given the nature of pre-market non-clinical testing for medical devices, these are typically prospective laboratory tests conducted by the manufacturer or accredited testing facilities. The manufacturer is Medentika® GmbH (Huegelsheim, Germany), suggesting the testing likely occurred in Germany or at internationally recognized labs.

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

This information is not applicable to the provided document. The ground truth for this device is established through engineering specifications, material standards (e.g., ASTM F136), and validated manufacturing processes, not through human expert consensus on diagnostic images.

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

This information is not applicable to the provided document, as it describes non-clinical engineering and manufacturing validation, not a multi-reader clinical study for AI.

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 information is not applicable to the provided document. This device is a physical dental abutment and its associated CAD/CAM workflow, not an AI-based diagnostic tool that would require human reader studies. The document explicitly states: "No clinical data were included in this submission."

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

This information is not applicable to the provided document. While the device utilizes CAD/CAM software and milling machines, it is a physical product manufactured through a workflow, not a standalone AI algorithm whose performance needs to be assessed in isolation. The software functions as a design and manufacturing aid, not a diagnostic or decision-making algorithm.

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

The "ground truth" in this context refers to established engineering and material standards:

• Standards Compliance: Adherence to ISO standards (e.g., ISO 14801 for mechanical strength, ISO 10993 for biocompatibility, ISO 17665 for sterilization).
• Dimensional Accuracy: Verification against established design parameters and compatibility specifications for dental implants (e.g., OEM implant body and abutment dimensions).
• Material Specifications: Conformance to ASTM F136 for titanium alloy and specifications for zirconia and cement.
• Software Design Parameters: The "ground truth" for the CAD software validation is the pre-defined maximum and minimum design parameters that the software must enforce.

8. The sample size for the training set:

This information is not applicable to the provided document. The "device" in question is a physical dental abutment and its manufacturing workflow, not an AI/ML model that requires a training set. The CAD/CAM software itself is validated, not "trained" on a dataset in the AI sense.

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

This information is not applicable to the provided document for the same reasons as point 8.

Here's an analysis of the acceptance criteria and supporting studies based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" in a quantitative manner as one might expect for a typical performance study of a diagnostic device. Instead, the focus is on demonstrating "substantial equivalence" to predicate devices through various tests.

The primary method for demonstrating substantial equivalence related to performance was a comparative fatigue test.

While specific numerical acceptance criteria (e.g., minimum force for fatigue failure) are not provided, the reported device performance is that the subject device met the performance of the predicate device.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size for Fatigue Testing: The document does not specify the exact sample size used for the comparative fatigue test per ISO 14801. It only states that the test was "conducted on the subject device and primary predicate."
• Data Provenance: Not explicitly stated as retrospective or prospective, or country of origin for the test data. However, the submitting company, MegaGen Implant Co., Ltd., is located in the Republic of Korea.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

This information is not applicable as this submission is for a medical device (dental implant) and its physical properties (e.g., fatigue strength), not for an AI/diagnostic software where expert ground truth would be established. The "ground truth" here is the physical performance of the device under mechanical stress.

4. Adjudication Method for the Test Set

This information is not applicable for the same reason as point 3. Adjudication methods like "2+1" or "3+1" are typically used for establishing ground truth in clinical image interpretation or diagnostic studies.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

This information is not applicable. An MRMC study is relevant for evaluating the impact of AI on human reader performance in diagnostic tasks, not for the physical performance of a dental implant.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This information is not applicable. This is not an AI algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the device's performance is established through physical testing and engineering standards. Specifically, comparative fatigue testing per ISO 14801 was used. This standard defines methods for dynamic fatigue testing of endosseous dental implants.
