The provided document is a 510(k) clearance letter for a dental resin, not a study report for an AI/ML device. Therefore, it does not contain the information requested in your prompt regarding acceptance criteria and studies for device performance as it pertains to an AI/ML device.

The document discusses the substantial equivalence of a new dental resin (Flexible Partial Resin) to a predicate device (Flexible Block) based on:

• Indications for Use Comparison: Both devices are indicated for fabricating dental appliances such as dental plates, bite plates, partial denture frameworks, and clasps. The predicate has additional indications not claimed by the subject device.
• Technological Comparison: The devices are compared based on material composition and principle of operation. The subject device uses a methacrylate/dimethacrylate-based resin and 3D printing (DLP), while the predicate uses polyamide and milling from blocks.
• Performance Testing: Non-clinical tests were conducted to compare the physical properties of the subject device to the predicate device using ASTM standards (Flexural Strength and Modulus, Tensile Strength, Elongation at Break, Impact Strength, Water Absorption). Printing accuracy was also tested.
• Biocompatibility: The subject device was evaluated per ISO 10993-1:2018, leveraging data from a reference device.

Key takeaway for your request:

The FDA 510(k) clearance letter for "Flexible Partial Resin" does not describe an AI/ML device or a study involving AI/ML performance. Therefore, it does not contain information about:

• Acceptance criteria and performance for an AI/ML device.
• Sample sizes for test sets, data provenance, or ground truth establishment relevant to AI/ML.
• Number of experts, adjudication methods, MRMC studies, or standalone algorithm performance for AI/ML.
• Training set size or ground truth for an AI/ML model.

Instead, it details the substantial equivalence of a new dental material (resin) to existing predicate devices based on physical, chemical, and biocompatibility properties.

Therefore, many of the requested elements pertaining to AI/ML device studies (e.g., test set data provenance, expert ground truth, adjudication methods, MRMC studies, standalone algorithm performance, training set details) are not applicable to this document.

However, I can extract the acceptance criteria and performance data for the material properties of the SprintRay Apex Flex device as presented in the document.

Analysis of Acceptance Criteria and Device Performance for SprintRay Apex Flex

The "acceptance criteria" for this device are implicitly derived from the performance of the predicate and reference devices, and conformance to industry consensus standards like ISO 20795-1. The SprintRay Apex Flex is demonstrated to be substantially equivalent to these devices by meeting comparable performance metrics.

1. Table of Acceptance Criteria and Reported Device Performance

The document presents a comparison of the SprintRay Apex Flex (Subject Device) against its primary predicate (Flex-Star V), secondary predicate (TCS® Unbreakable), and a reference device (SprintRay NightGuard Flex). The "acceptance criteria" are not explicitly stated as numerical thresholds but are implied by the measured values of the predicate devices, particularly the Flex-Star V as the primary predicate. The subject device must show comparable or improved performance without raising new safety or effectiveness concerns.

Summary of Device Performance: SprintRay Apex Flex demonstrates comparable or in some cases superior physical properties (e.g., flexural modulus, lower water sorption) compared to the predicate and reference devices, while meeting biocompatibility and other standard requirements.

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

The document does not specify a "test set" in the context of an AI/ML model for diagnostic performance. The "testing" refers to bench testing of material properties.

• Sample Size: The exact number of samples tested for each material property (e.g., flexural strength, sorption) is not provided. The results are reported with mean values and standard deviations, implying multiple samples were tested for each property as per ISO standards.
• Data Provenance: The data is generated from bench testing of the manufactured SprintRay Apex Flex resin. The "country of origin" for this data would be the location where these laboratory tests were conducted, which is not specified in the document but is typically part of the manufacturer's internal testing process. The nature of the data is prospective in the sense that the manufacturer specifically produced and tested samples of the Apex Flex resin for this 510(k) submission.

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

This question is not applicable as the document describes a material and its physical properties, not an AI/ML diagnostic device requiring expert interpretation for ground truth. The "ground truth" for material properties is established by standardized test methods (e.g., ISO 20795-1) and measurement equipment, not by human experts.

4. Adjudication Method for the Test Set

Not applicable. As the "test set" refers to material samples undergoing physical and chemical tests, there is no need for adjudicating human interpretations.

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 document pertains to a dental material, not an AI-assisted diagnostic device.
