The provided text describes a 510(k) premarket notification for a GR Resin System MSI, a light-curable polymerizable resin used for fabricating orthodontic and dental objects. However, it does not contain information about a study proving the device meets acceptance criteria related to artificial intelligence (AI) performance, human reader improvement with AI assistance (MRMC), or standalone algorithm performance.

This document focuses on demonstrating substantial equivalence to predicate devices based on indications for use, chemical composition, manufacturing technology, physical state, curing method, and compliance with performance, biocompatibility, and shelf-life standards. The "Performance Testing" section only states that testing was performed in accordance with ISO 20795-2 for Flexural Strength, Flexural modulus / Bending module, Water Sorption, and Solubility.

Therefore, I cannot provide the requested information regarding acceptance criteria and study details for an AI/human-in-the-loop device, as the provided text pertains to a different type of medical device (a dental resin).

To answer your request, I would need a document describing the study and acceptance criteria for an AI-powered medical device.

Thermeo powder / Thermeo liquid is a heat cured, moldable, acrylic compound system for use in the fabrication of dental appliances such as mouthguards, bruxism and TMJ splint appliances, and bite splints.

The Thermeo blank is a disc intended for the fabrication of dental appliances such as mouthguards, buxism and TMJ splint appliances, and bite splints using CAD/CAM milling machines.

The Thermeo powder/Thermeo liquid is a two-compound mixable device, containing a powder component and a liquid component. The device is heat cured for the fabrication of dental appliances.

The Thermeo blanks are pre-made by pro3dure using the two-part mixable device. The Thermeo blank is intended to be used in conjunction with CAD/CAM milling technology systems.

The provided document is an FDA 510(k) Premarket Notification for a dental device, the "Thermeo System." It is a regulatory submission for establishing substantial equivalence to existing devices, not a study reporting on the performance of an AI/ML diagnostic system.

The request asks for information typically found in clinical validation studies for AI/ML-driven medical devices, such as:

1. Acceptance criteria and device performance table.
2. Sample size and data provenance for test sets.
3. Number and qualifications of experts for ground truth.
4. Adjudication method.
5. MRMC study details and effect size.
6. Standalone algorithm performance.
7. Type of ground truth used.
8. Training set sample size.
9. Ground truth establishment for training set.

This document, however, describes a physical dental material system (Thermeo powder/liquid and Thermeo blank for dental appliances) and its substantial equivalence to predicate devices based on material properties, manufacturing processes, and safety (biocompatibility, shelf life), not on the diagnostic performance of an algorithm.

Therefore, most of the information requested, which pertains to the validation of an AI/ML diagnostic algorithm, cannot be extracted from this document, as it is not relevant to the Thermeo System's 510(k) submission.

Here's what can be gathered, addressing the relevant parts of your request within the context of this device:

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

The document indicates that performance testing was conducted according to ISO 20795-2 for the "Thermeo System." This standard covers dental base polymers. The specific mechanical properties measured were:

• Flexural modulus
• Flexural Strength
• Tensile Strength
• Elongation at Break

However, the document does not provide a table with specific acceptance criteria values (e.g., minimum flexural strength) nor the numerical results (reported device performance) for these tests. It only states that testing was "performed in accordance with" the standard. For a 510(k), demonstrating compliance with a recognized standard often suffices without explicitly listing all raw data in the summary.

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

• Sample Size: Not specified in the provided text.
• Data Provenance: The device manufacturer, Pro3dure Medical GmbH, is located in Germany. Testing would likely be conducted at their facilities or a contracted lab. The document does not specify if the testing was retrospective or prospective in terms of data collection for this type of material performance test.

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

• Not Applicable. This is a physical material compliance test, not a diagnostic algorithm requiring expert ground truth for images. Performance is measured using standardized mechanical and chemical testing methods.

4. Adjudication method for the test set:

• Not Applicable. See point 3.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:

• No. This is not an AI/ML diagnostic device, so an MRMC study is not relevant.

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

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

7. The type of ground truth used:

• For the performance testing (flexural modulus, strength, etc.), the "ground truth" is established by physical measurement results obtained through standardized testing protocols (ISO 20795-2).
• For biocompatibility, the "ground truth" is established by biocompatibility testing in accordance with ISO 10993-1, which assesses biological responses.
• For shelf-life, the "ground truth" is established by accelerated aging and real-time stability testing per ASTM F1980-16.

8. The sample size for the training set:

• Not Applicable. There is no "training set" as this is not a machine learning device.

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

• Not Applicable. See point 8.

In summary, the provided document is a regulatory submission for a physical dental product, and the requested performance evaluation criteria are primarily applicable to AI/ML diagnostic software, which is not the subject of this 510(k).

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't explicitly state "acceptance criteria" with numerical targets for each performance standard. Instead, it states that performance testing was performed in accordance with specific ISO standards. This implies that meeting the requirements specified within these standards constitutes the acceptance criteria. The "Reported Device Performance" column therefore reflects that the device successfully met these standards, as a conclusion of "substantial equivalence" is drawn.

  | ASTM F1980-16 (Standard Guide for Accelerated Aging of Sterile Medical Device Packages) | Shelf life of 2 years demonstrated through testing in accordance with ASTM F1980-16. |

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

The document does not specify the sample sizes used for the test sets in the performance, biocompatibility, or shelf-life studies. It also does not mention the country of origin of the data or whether the studies were retrospective or prospective.

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

This information is not provided in the document. The studies mentioned (performance, biocompatibility, shelf-life) are technical tests on material properties, not diagnostic studies requiring expert interpretation of results to establish "ground truth" in the way it's typically understood for AI/diagnostic devices.

4. Adjudication Method for the Test Set:

This information is not applicable/provided. The acceptance criteria are based on defined standards and physical/chemical testing, not on adjudicated expert opinions.

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

No, an MRMC comparative effectiveness study was not done. This type of study is typically performed for diagnostic devices where human readers (e.g., radiologists) interpret images or data, and the study aims to assess the impact of AI assistance on their performance. The GR-14 Resin System is a material used for manufacturing dentures, not a diagnostic device.

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

This concept is not applicable to the GR-14 Resin System. This device is a material, not an algorithm. The performance tests are inherently "standalone" in that they evaluate the material's properties directly, not its interaction with a human operator beyond proper manufacturing and curing processes.

7. The Type of Ground Truth Used:

For the performance testing, the "ground truth" is defined by the specifications and limits within the cited ISO and ASTM standards. For example, flexural strength must meet a certain value specified in ISO 20795-1. For biocompatibility, the ground truth is simply whether the material passes the tests outlined in ISO 10993-1, indicating it does not elicit adverse biological reactions.

8. The Sample Size for the Training Set:

This information is not applicable and therefore not provided. The GR-14 Resin System is a material, not an AI/machine learning algorithm that requires a "training set" of data.

9. How the Ground Truth for the Training Set was Established:

This information is not applicable and therefore not provided, as there is no training set for this type of device.

The GR-17 Resin System is a light-curable resin intended to be used in conjunction with extra-oral curing light equipment.

The GR-17 temporary is indicated for the fabrication, by additive manufacturing, of temporary anterior dental restorations.

The GR-17.1 temporary is indicated for the fabrication, by additive manufacturing, of temporary dental restorations, and for the fabrication, by additive manufacturing, of preformed denture teeth to be used in a denture.

GR-17 Resin System includes the GR-17 temporary and GR-17.1 temporary It and is made of functional methacrylic resins and inorganic fillers with particle sizes from 0.4 to 3 microns. It is available in seven shades based on the shade guide, A1, A2, A3, A3.5, B1, B2 and bleach. The resin is a liquid photo-curable material that is polymerized by image projection systems at 405nm to create temporary dental restorations, and preformed denture teeth to be used in a denture. The GR-17 Resin System is intended to be used in conjunction with an additive Computer-Aided Manufacturing (CAM) and curing system such as Nyomo, Rapidshape, Envisiontec or Asiga Systems.

The provided document is a 510(k) summary for the GR-17 Resin System, a temporary crown and bridge resin. It describes the device's characteristics and compares it to predicate and reference devices to demonstrate substantial equivalence. However, this document does not contain the detailed information required to describe acceptance criteria and the study that proves the device meets those criteria, specifically concerning performance metrics for an AI/algorithm-based device.

The document mentions "Performance testing for the GR-17 Resin System was performed in accordance with ISO 10477 and ISO 22112" and lists "Flexural Strength," "Modulus of Elasticity," "Water Absorption," and "Solubility" as physical and mechanical properties. This indicates testing for the material properties of the resin itself, not the performance of an AI/algorithm-based device.

Therefore, I cannot provide the requested information about acceptance criteria for an AI/algorithm, sample sizes for test/training sets, expert qualifications, adjudication methods, or MRMC studies, as these types of studies are not described in this regulatory submission for a dental resin.

The document covers a physical medical device (dental resin) and not an AI/algorithm device. Therefore, the specific questions about AI/algorithm performance metrics, sample sizes for AI tests, expert adjudication, MRMC studies, and standalone performance for AI are not applicable to the content provided.
