    Flexible Partial Resin is indicated for the fabrication of dental appliances such as dental plates, bite plates, partial denture frame-works and clasps.

    Device Description

    The subject device, Flexible Partial Resin, is a light-cured polymerizable resin for the fabrication of partial removable denture bases made in dental laboratories. The resin can be used in DLP printers utilizing a wavelength of 385nm and will be offered in G1 (standard pink), G3 (medium pink), and G4 (dark pink) shades formulated to match gingival tissue. The final medical device is a custom fitted appliance that is compliant to the dental professional's diagnosis and prescription.

    AI/ML Overview

    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.

    This document is for a material used in dental device fabrication, not an AI-powered diagnostic or assistive tool.

    The Autoclavable Cassettes are used in healthcare facilities to organize surgical and prosthetic instruments during sterilization, storage, and transport during and after surgical uses. The Autoclavable Cassettes are not intended to maintain sterility; they are intended to be used in conjunction with a legally marketed, validated sterilization wrap to maintain the sterility of the enclosed devices.

    Sterilization parameters:

    Pre-vacuum steam: 132°C (270°F) for 4 minutes with 30 minutes drying time.

    Sterilization validations for the worst-case Autoclavable Cassette and instruments. The Autoclavable Cassettes are validated for a maximum load of 641 grams for Glided Surgical Kit, 476 grams for Glidewell HTTM Implant Surgical Kit. and 192 grams for Glidewell™ Prosthetic Kit.

    Device Description

    The Autoclavable Cassettes are designed to store, organize, and protect various surgical and prosthetic instruments that are sterilized by the healthcare provider. The Autoclavable Cassettes are composed of three main components: a lid, a base, and a tray. The components are made of polyphenylsulfone PPSU. The tray has silicone rubber grommets to hold the instruments in place. The lid latches to the base holds the tray, and all three components are designed to secure the kit into a single unit. The cassette protects the interior components during sterilization and subsequent storage. The kits are perforated to allow for penetration of moist heat during steam sterilization and require the use of an FDA-cleared sterilization wrap to maintain sterility. To facilitate the surgical procedure and the correct use and the positioning of the instrument, the tray has instrument descriptions on the surface.

    Surgical and prosthetic instruments of the Glidewell Implant System are intended to be placed in the Autoclavable Cassette. These surgical and prosthetic instruments which are the contents of the sterilization cassette are all Class 1 exempt as described in 21 CFR 872.3980 (Endosseous dental implant accessories).

    AI/ML Overview

    The provided text describes the acceptance criteria and the results of the study conducted to demonstrate the safety and effectiveness of the Autoclavable Cassette (Glidewell HT™ Implant Guided Surgical Kit, Glidewell HT™ Implant Surgical Kit, Glidewell™ Prosthetic Kit).

    Here's a breakdown of the requested information:

    1. Table of Acceptance Criteria and Reported Device Performance

    Type of TestingTest PurposeAcceptance CriteriaReported Device Performance

    Hemoglobin Test: 70%, which is considered non-cytotoxic.Pass
    Packaging Validation (ASTM D4169-23e1)Packaging performance testingPackaging must withstand the distribution environmentPass

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

    The document does not explicitly state the specific "sample size" in terms of number of individual units tested for each non-clinical test. However, it indicates:

    • Worst-case cassettes were tested for performance based on critical impact factors including weight, vent to volume ratio, and worst-case instruments to be contained.
    • Data Provenance: The study is reported as non-clinical testing conducted by the manufacturer, Prismatik Dentalcraft, Inc. The document doesn't specify the country of origin of the data, but it refers to international standards (e.g., ANSI/AAMI, ISO, ASTM). The nature of these tests suggests they are prospective in that they are performed specifically to validate the device's performance against predefined criteria.

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

    This information is not applicable and not provided in the document. The tests performed are non-clinical, objective evaluations against established scientific and engineering standards (e.g., visual inspection for soil, chemical tests for residue, biological indicators for sterility, mechanical testing for durability). They do not involve human interpretation of medical images or expert consensus to establish a "ground truth" in the way a diagnostic AI device would.

    4. Adjudication Method for the Test Set

    This information is not applicable and not provided in the document for the reasons stated above. Adjudication typically applies to studies where human interpretation or consensus is required to determine a reference standard.

    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 and not provided in the document. The device in question is an "Autoclavable Cassette" (sterilization wrap accessory), not an AI-powered diagnostic tool. Therefore, an MRMC comparative effectiveness study comparing human readers with and without AI assistance is irrelevant to this device type.

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

    This information is not applicable and not provided in the document. The device is a physical medical device (sterilization cassette), not an algorithm or software. Therefore, the concept of "standalone algorithm performance" is not relevant.

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

    The "ground truth" for the non-clinical tests is based on objective, measurable standards and criteria established by recognized regulatory and industry standards (e.g., SAL ≤10^-6 for sterility, specific chemical residue limits for cleaning, visual inspection for damage, cellular vitality percentages for biocompatibility). These are not based on expert consensus, pathology, or outcomes data in the usual sense of diagnostic or therapeutic devices.

    8. The Sample Size for the Training Set

    This information is not applicable and not provided in the document. The device is a physical product and does not involve AI/machine learning, thus there is no "training set."

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

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

    AI/ML Overview

    Here's an analysis of the provided text, focusing on the acceptance criteria and the study proving the device meets them, presented in the requested format.

    It's important to note that this document is a 510(k) Summary, which is a regulatory submission for medical devices. It primarily focuses on demonstrating substantial equivalence to a predicate device rather than comprehensive clinical trial results. Therefore, some information typically found in a full clinical study report (like detailed sample sizes for training sets or expert qualifications for ground truth) may not be explicitly stated for components not directly studied in this submission. The "study" described herein refers primarily to the in vitro antimicrobial testing.

    Acceptance Criteria and Device Performance

    Glidewell™ 3DP Denture Base Resin is a Class II device (Product Code EBI, Regulation Number 21 CFR 872.3760). The primary focus of the additional testing in this 510(k) submission (K241493) seems to be the antimicrobial properties of the resin, as its physical properties are stated to be identical to the predicate device (K213765).

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

    • Antimicrobial Tests (Test Set): The specific number of samples (replicates) used for each microorganism in the in vitro tests (ASTM E2180-07 and ASTM E2647-13) is not explicitly stated in this summary. These are typically material tests on prepared resin samples, not patient-derived data.
    • Physical Properties: Not explicitly stated as the data for the subject device is leveraged from the predicate device (K213765), implying prior testing was performed for the predicate.
    • Data Provenance: The studies are in vitro laboratory tests conducted by the manufacturer or their contracted labs. The provenance is internal to the manufacturer (Prismatik Dentalcraft, Inc.) and is retrospective as it supports a 510(k) submission. No country of origin for data generation is specified beyond the company's location in Irvine, California, USA.

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

    • Not Applicable. For these in vitro material and microbiology tests, "ground truth" is established by the standardized methods themselves (e.g., cell counts, optical density measurements, mechanical property testing according to ISO standards). This is not equivalent to establishing ground truth for AI algorithms based on expert interpretation of medical images. The tests measure objective physical and biological properties.

    4. Adjudication Method for the Test Set

    • Not Applicable. As these are in vitro laboratory tests measuring objective properties, an adjudication method among experts (like 2+1 or 3+1 for image reviews) is not relevant.

    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 device is a denture base resin, not an AI software intended to assist human readers (e.g., radiologists). Therefore, an MRMC comparative effectiveness study is not relevant to this submission. The summary explicitly states: "Clinical studies have not been conducted to demonstrate that the presence of silver sodium hydrogen zirconium phosphate in Glidewell™ 3DP Denture Base Resin results in improved clinical outcomes."

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

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

    7. The Type of Ground Truth Used

    • For Antimicrobial Tests: Ground truth is established by quantitative microbial culture methods (viable plate counts) as per ASTM E2180-07 and ASTM E2647-13. The "control samples of regular denture without antimicrobial agent" serve as the baseline for comparison.
    • For Physical Properties: Ground truth is established by standardized mechanical testing procedures as per ISO 20795-1:2013.
    • For Biocompatibility: Ground truth is established by standardized biological evaluation tests per ISO 10993-1:2018 and ISO 7405:2018.

    8. The Sample Size for the Training Set

    • Not Applicable. There is no "training set" in the context of this device because it is a physical material, not an AI/ML algorithm that requires training data.

    9. How the Ground Truth for the Training Set Was Established

    • Not Applicable. As there is no training set for an AI/ML algorithm.

    AI/ML Overview

    The provided document is a 510(k) Summary for a dental device (Inclusive® Titanium Abutments). It details the device's technical characteristics and claims substantial equivalence to a predicate device based on non-clinical testing. However, it does not include specific quantitative acceptance criteria or detailed results of a study designed to compare the device performance against such criteria.

    The document discusses "performance data" in general terms, referring to several non-clinical tests (Biocompatibility, Mechanical Properties, Sterilization Validation, Shelf Life and Packaging Validation, and Use in MR Environment). It states that these tests were performed to "demonstrate substantial equivalence" and to "address questions related to substantial equivalence based on the differences in technical specifications," but it doesn't present the data in a way that allows for filling out the requested table of acceptance criteria and reported performance.

    Therefore, I cannot provide a table of acceptance criteria and reported device performance, nor can I answer questions 2 through 9 regarding sample size, data provenance, expert involvement, adjudication, MRMC studies, or training set details, as this information is not present in the provided text.

    The document explicitly states:

    • "Non-clinical testing data are submitted to demonstrate substantial equivalence. No clinical data was included in this submission."

    This indicates that clinical trials with human subjects, which would typically involve expert ground truth establishment and detailed performance metrics comparing against specific acceptance criteria, were not part of this submission for substantial equivalence.

    The "Mechanical Properties" section mentions:

    • "Static load and fatigue testing of the implant/abutment assembly was considered according to the FDA Guidance Document, Guidance for Industry and FDA Staff Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments and ISO 14801:2016 standard with the worst-case scenario. The fatigue limit data demonstrated that the subject device has sufficient strength for its intended use."

    This implies that there were performance targets based on ISO 14801:2016 for fatigue strength, but the specific acceptance critiera (e.g., minimum fatigue strength in Newtons) and the actual reported performance values are not provided in this summary. It only states that the device "has sufficient strength."

    Intended Use

    CloudPoint FastDesign Chairside is intended as an aid to the restoration of chewing function in partially or fully edentulous mandibles and maxillae. CloudPoint FastDesign Chairside is intended for use by a dental practitioner or dental laboratory staff for designing the patient-matched component of a two-piece hybrid dental implant abutment. The resulting abutment design is intended to be used by the manufacturer of an endosseous dental implant to create the final device.

    Device Description

    CloudPoint FastDesign Chairside (also known as FastDesign), is a software suite intended to be used by trained dental practitioners or dental laboratory staff to design the patient-matched component of a two-piece hybrid dental implant abutment. A titanium base-type abutment and hybrid abutment-crown component are combined to make the two-piece hybrid dental implant abutment. The software allows a dental practitioner or dental laboratory staff to design the matching dental abutment based on imported scan data containing topographical characteristics of the patient's dentition. The resulting abutment design will be exported to a remote milling machine to make the final device.

    CloudPoint FastDesign Chairside, is restricted to be used with 510(k) cleared abutment systems. The software includes design parameters from the 510(k) cleared abutment systems such as maximum and minimum dimensions (e.g., abutment post height, gingival height, angulation, gingival margin diameter, etc.). CloudPoint FastDesign Chairside designs the endosseous dental implant abutment under the directions of a clinical professional and maintaining accordance to the requirements of the compatible 510(k) cleared abutment systems with cleared design parameter size ranges.

    AI/ML Overview

    The provided text describes the "CloudPoint FastDesign Chairside," a dental abutment design software. However, it does not contain the detailed acceptance criteria for device performance, nor the specifics of a study proving the device meets those criteria, as typically requested in your prompt.

    The document primarily focuses on demonstrating substantial equivalence to a predicate device (Abutment Design K200100) based on intended use, indications for use, and technological characteristics. It mentions "Software verification and validation" and "Cybersecurity Analysis" as non-clinical data submitted, but does not provide a table of acceptance criteria with reported device performance.

    Therefore, I cannot fulfill your request for:

    1. A table of acceptance criteria and the reported device performance: This information is not present in the provided document.
