    AI/ML Overview

    I am sorry, but the provided text from the FDA 510(k) Clearance Letter does not contain any information about acceptance criteria, device performance metrics, or study details such as sample size, data provenance, expert ground truth establishment, adjudication methods, or MRMC studies for an AI/CADe device.

    The document describes the regulatory clearance for a dental material device called "NOBILCAM IMPAK Disc", which is an acrylic compound used for fabricating dental appliances.

    It focuses on:

    • Physical and Chemical Properties Tests: These are bench tests comparing the material properties (e.g., appearance, dimension, color stability, water sorption, hardness, flexural strength) of the subject device to a predicate device and relevant ISO/ADA standards.
    • Biocompatibility Tests: These are biological safety tests performed according to ISO 7405 and ISO 10993 standards (e.g., cytotoxicity, irritation, sensitization).
    • Technological Characteristics Comparison: A table comparing ingredients, physical form, indications for use, sterility, storage conditions, and packaging with predicate and reference devices.

    There is no mention of:

    • An AI or CADe device.
    • Any diagnostic or detection performance metrics (e.g., sensitivity, specificity, AUC).
    • Human reader studies or multi-reader multi-case (MRMC) comparative effectiveness studies.
    • Ground truth established by experts or pathology.
    • Sample sizes for training or test sets for an algorithm.

    Therefore, I cannot fulfill your request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria based on this document, as the document pertains to a physical dental material, not an AI software or diagnostic device that would typically have the performance metrics and study types you've listed.

    Intended Use

    Denture Base Polymers is used for fabrication and repair of partial and full denture base for patients with missing teeth.

    Device Description

    Denture Base Polymers contains powder and liquid, wherein the power is mainly composed of polymethyl methacrylate, and the main composition of the liquid is methyl methacrylate.

    AI/ML Overview

    This document is a 510(k) premarket notification for a medical device called "Denture Base Polymers." It's a submission to the FDA (U.S. Food & Drug Administration) to demonstrate that the device is "substantially equivalent" to legally marketed predicate devices, meaning it's as safe and effective as a device already on the market.

    However, the provided text does not describe a study involving "acceptance criteria" and "device performance" in the context of an AI/algorithm-based diagnostic or prognostic device. It's for a dental material (denture base polymers), which is a physical product, not a software or AI device.

    Therefore, I cannot extract the information required for your request, such as a table of acceptance criteria for AI performance, sample sizes for test sets in an AI study, expert ground truth establishment, MRMC studies, or standalone algorithm performance.

    The document primarily focuses on:

    • Chemical composition of the denture material.
    • Technological characteristics (e.g., heat curing, self-curing).
    • Physical and chemical properties that meet ISO standards (ISO 20795-1 for Dental base material).
    • Biocompatibility testing (following ISO 10993 standards) to ensure it's safe for use in the human body.
    • Comparison to predicate devices to demonstrate substantial equivalence for its intended use (fabrication and repair of partial and full denture base).

    It explicitly states: "10. Clinical Performance Data: Not applicable. Clinical performance testing has not been performed on the subject device." This further confirms that no clinical studies in the sense of a performance study for an AI device were conducted or are being reported here.

    Study to prove acceptance criteria:

    The study performed was a series of bench tests to evaluate the physical, chemical, and biological properties of the Flexible Block device.

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

    • Sample Size: Not explicitly stated in terms of number of blocks tested for each physical property. However, it mentions "We selected our Flexible Block (Model: monolayer; Specification: 98×20mm; Shade: Clear) as the representative in biocompatibility tests," implying a single representative model was used for biocompatibility.
    • Data Provenance: The tests were conducted by the manufacturer, Shandong Huge Dental Material Corporation, based in China ("No. 68 Shanhai Road, Donggang District Rizhao City, Shandong 276800 China"). This is a retrospective evaluation of a newly manufactured material against established standards.

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

    • Not Applicable. For a material device, "ground truth" is established by adherence to physical, chemical, and biological standards (e.g., ASTM, ISO). There are no human "experts" establishing ground truth in the context of diagnostic performance here. The "experts" would be the personnel in the testing laboratories who perform the tests according to the specified standards.

    4. Adjudication method for the test set

    • Not Applicable. There is no adjudication method in the context of evaluating a material against objective physical and chemical standards.

    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 is a material device, not an AI-enabled diagnostic tool. No MRMC study was performed.

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

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

    7. The type of ground truth used

    • The "ground truth" for this device is based on established material science standards (e.g., ASTM D638, ASTM D570, ASTM D256, ASTM D790) for physical properties, and international biocompatibility standards (ISO 10993 series) for biological safety.

    8. The sample size for the training set

    • Not Applicable. This is a material device, not a machine learning model. There is no concept of a "training set" in this context. The manufacturing process of the material could be seen as analogous to a "training set" in a very abstract sense (optimizing the material's properties), but it does not use a data-driven training set like AI models.

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

    • Not Applicable. As there is no training set for an AI model, there is no ground truth established for it. The development of the material's properties would be based on material science principles and iterative testing against target performance specifications.

    Intended Use

    The Orthodontic Appliance is indicated for the correction of tooth malocclusion in patients with permanent dentition. The Orthodontic Appliance moves the teeth by continuous gentle force.

    Device Description

    The Orthodontic Appliance is a series of clear, lightweight, plastic aligners that are used to replace traditional orthodontic wires and brackets for the alignment of maloccluded or misaligned teeth. This series of aligners moves the teeth gently, and in small increments, from their original to their final treated position for improved dental alignment. The product is made of a polymer thermoplastic material (polyvinyl ester mixture) by pressing.

    The doctor-prescribed Orthodontic Appliance are provided non-sterile and are customized for each patient according to the 3D printed data designed by Clear Aligner Design Software. Shandong Huge Dental Material Corporation manufactures the Orthodontic Appliance by thermoforming commercially available thermoplastic material and send them to the clinician. The clinician confirms the fit of the aligners upon delivery to the patient and monitors the patient's progress throughout treatment. Depending on the patient need and the treatment plan, a series of aligners may be used. The duration of use for each pair of appliance is 2-3 weeks, wear the appliances for at least 20 hours every day and it is to be worn except during eating or cleaning of the oral cavity.

    The type of Orthodontic Appliance is LX-A with various thickness so that the clinician can select suitable thickness based on patients' teeth micromaxillary deformity conditions. Different thickness are identical in chemical compositions, indications for use, functions, performance characteristics, operation principle and other aspects.

    AI/ML Overview

    The provided document is a 510(k) summary for an Orthodontic Appliance. It details the device's indications for use, its description, comparison to a predicate device, and non-clinical performance testing. However, it explicitly states that no clinical testing was required or performed to support the device's clearance.

    Therefore, many of the requested details regarding acceptance criteria and a study proving the device meets those criteria cannot be extracted from this document, as such a study was not conducted for human performance. The focus of the provided document is on demonstrating substantial equivalence to a predicate device through non-clinical means (material properties, biocompatibility, and software V&V for ordering/processing).

    Here's what can be extracted based on the information provided:

    Acceptance Criteria and Device Performance (Non-Clinical)

    Since no clinical study was performed, the "device performance" relies on non-clinical tests and comparison to a predicate. The acceptance criteria essentially stem from demonstrating that the subject device is comparable to the predicate device in terms of performance characteristics.

    Acceptance Criteria (What was tested for)Reported Device Performance (Met, or comparable to predicate)
    Physical and Mechanical Properties:The document states: "The performance testing for the subject device was performed and showed that the subject device meets all internal final inspection standard, while the physical and mechanical properties as well as the biocompatibility of the thermoplastic materials used to fabricate the aligners have previously been demonstrated by the manufacturer of the base materials."

    Specific tested items included:Appearance and surface characteristicsDimensionspH valueElasticity variableVolume weightWater sorptionSolubilityThe comparative testing between the proposed and predicate device for these properties was conducted to demonstrate substantial equivalence. The implication is that the subject device's performance aligns with or is sufficiently similar to the predicate device and established material properties. |
    | Biocompatibility (ISO 10993 Standards): | The document states: "Biocompatibility tests were performed to satisfied the ISO 10993 standards. The test results of the tests met the requirements of the study protocols..."

    Specific tests conducted:Cytotoxicity (ISO 10993-5)Skin Sensitization (ISO 10993-10)Intracutaneous Reactivity (ISO 10993-10)Subchronic systemic toxicity (ISO 10993-11)Genotoxicity (ISO 10993-3)The results indicated the device met the requirements, supported by the long history of safe use of the thermoplastic material and the predicate device's information. |
    | Software Verification & Validation: | The document states: "Software verification and validation testing were conducted on the software that facilitates ordering and processing of the Orthodontic Appliance to support that the device is as safe and effective as the predicates. Documentation was provided as recommended by FDA's Guidance... The software for this device was considered as a 'moderate' level of concern." This indicates that the software was tested and verified to perform its intended functions related to device ordering and processing, meeting the requirements for its risk classification. |


    Study Details (Based on the document's claims of no clinical testing required)

    Many of these categories are not applicable (N/A) because the submission explicitly states:
    "The performance of Orthodontic Appliance in the clinical environment has been well established since the first such devices were cleared by the FDA in 1998 under product code NXC. Therefore, there was no clinical testing required to support Orthodontic Appliance, as the indications for use is equivalent to the predicate device."

    1. Sample sizes used for the test set and the data provenance:

      • Clinical Test Set: N/A (No clinical test set was used for human performance evaluation).
      • Non-Clinical Test Set: Not specified in terms of sample numbers, but tests were performed on material samples and the device itself (e.g., for dimensions, appearance, physical/chemical properties). Data provenance is from Shandong Huge Dental Material Corporation's internal testing and material suppliers' data.
        • Biocompatibility Tests: Sample sizes for ISO 10993 tests are not explicitly mentioned in this summary, but these are standard lab tests performed on material extracts or samples.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: N/A (No clinical ground truth was established as no clinical study was performed for this 510(k)).

    3. Adjudication method (e.g. 2+1, 3+1, none) for the test set: N/A (No clinical test set requiring adjudication).

    4. 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: N/A (No MRMC study was performed as no clinical study was conducted, and the device is a physical appliance, not an AI-based diagnostic tool for human readers).

    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: N/A (The device is a physical appliance, not an algorithm, and no standalone clinical performance was evaluated). Non-clinical standalone tests were performed as detailed in the table above (physical/mechanical properties, biocompatibility).

    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): N/A (No clinical ground truth as no clinical study for human performance was conducted. For non-clinical tests, "ground truth" would be the established ISO standards and material specifications).

    7. The sample size for the training set: N/A (The device is a physical orthodontic appliance, not a machine learning model. Therefore, there's no "training set" in the context of an AI/ML device). The design of the appliance is based on 3D printed data generated by "Clear Aligner Design Software", but this itself is part of the manufacturing process, not a training set for an AI algorithm.

    8. How the ground truth for the training set was established: N/A (No training set for an AI/ML model).

    Device Description

    Glass Ionomer Cement (Luting) has two models: Luting II. It is a device composed of various materials mainly including Silica, Alumina, Strontium Fluoride in the powder composition and Poly Carboxylic Acid in the liquid composition which intended to serve as luting to affix dental devices such as metal-based inlays, onlays, crowns, bridges, and orthodontic bands. It's a powder liquid system, with each part is packaged separately when not in use. The basic operation principle of Glass Ionomer Cement (Luting) is acid-base reaction.

    AI/ML Overview

    The provided document is a 510(k) summary for a "Glass Ionomer Cement (Luting)" device. It focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study proving a device meets specific acceptance criteria based on algorithm-driven performance. Therefore, most of the requested information about AI/algorithm-related studies (sample sizes, ground truth establishment, expert adjudication, MRMC studies, standalone performance) is not applicable to this document.

    However, the document does contain a table of acceptance criteria and reported performance for physical and chemical properties based on the ISO 9917-1:2007 standard.

    Here's the information that can be extracted:

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

    The document does not specify exact sample sizes for each physical/chemical property test. It mentions that "Biocompatibility tests were performed to satisfied the ISO 10993 standards," but does not detail the specific sample counts for those tests. The data provenance is internal testing conducted by SHANDONG HUGE DENTAL MATERIAL CORPORATION, presumably prospective testing for this specific device.

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

    Not applicable. The tests are for physical and chemical properties, measured objectively according to ISO standards, not interpreted by human experts.

    4. Adjudication method for the test set

    Not applicable. The tests are objective measurements, not subject to adjudication.

    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 is a dental cement, not an AI-powered diagnostic device.

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

    Not applicable. This is a dental cement, not an algorithm.

    7. The type of ground truth used

    The "ground truth" for the physical and chemical property tests is defined by the specific measurement methodologies and acceptable ranges stipulated in the ISO 9917-1:2007 standard. For biocompatibility, the ground truth would be the thresholds and methodologies defined by ISO 10993 standards.

    8. The sample size for the training set

    Not applicable. There is no AI algorithm being trained.

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

    Not applicable. There is no AI algorithm being trained.
