    Intended Use

    DESS® dental implants are indicated for surgical placement in the upper or lower jaw in edentulous or partially edentulous patients for anchoring or supporting tooth replacements to restore patient esthetics and chewing function. They are designed to support single or multi-unit restorations in splinted or non-splinted applications, as well as to support overdenture attachment systems. DESS® dental implants may be used for immediate or early implantation following extraction or loss of natural teeth, and may be used for immediate or delayed loading techniques. Implants may be loaded immediately when good primary stability is achieved and occlusal loading is appropriate.

    DESS® NEO GM Dental Implants are compatible with DESS® Dental Smart Solutions abutments having the identical NEO GM connection manufactured by Terrats Medical SL.

    DESS® NEO GM Dental Implants with a diameter of 3.5 mm are indicated for use in reduced interdental spaces, where there is not enough alveolar bone for a larger diameter implant. The use of 3.5 mm implants is intended only for rehabilitation of the anterior region of the mouth.

    DESS® Dental Smart Solutions abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for prosthetic restorations.

    All digitally designed custom abutments for use with DESS® Pre-Milled Blank abutments are to be sent to a Terrats Medical validated milling center for manufacture.

    AI/ML Overview

    The provided FDA 510(k) Clearance Letter for DESS® Dental Implants (K251280) does not contain information about acceptance criteria or a specific study proving the device meets those criteria in the context of AI/ML device performance.

    The document is a clearance letter for a dental implant system, which is a physical medical device, not an AI/ML-driven diagnostic or treatment planning software. Therefore, the questions related to AI/ML device performance (such as sample size for test/training sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, and ground truth) are not applicable to the content provided.

    The document primarily focuses on demonstrating substantial equivalence to predicate devices based on:

    • Intended Use and Indications for Use
    • Technological Characteristics (design, materials, surface treatment, sterilization methods, dimensions)
    • Performance Data (non-clinical data such as MRI review, sterilization validation, bacterial endotoxin testing, shelf life, biocompatibility, and mechanical testing according to ISO 14801).

    Since the request specifically asks for AI/ML-related performance evaluation, and the provided document is not for an AI/ML device, I cannot fulfill the request as stated with the given input.

    However, I can extract the non-clinical performance data and the comparison to predicate devices, which serve as the "study" and "acceptance criteria" for this type of physical medical device in the context of a 510(k) submission.

    Non-Clinical Performance Data (Serving as "Study" for Substantial Equivalence):

    1. Worst-Case MRI Review:

      • Method: Scientific rationale and published literature (T.O. Woods, J.G. Delfino, and S. Rajan, "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices," Journal of Testing and Evaluation Volume 49, No. 2 (March/April 2021): 783–795).
      • Scope: Evaluated all compatible implant bodies, abutments, and fixation screws and their material composition.
      • Parameters: Magnetically induced displacement force and torque, per FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment."
      • Outcome: Rationale addressed parameters; device components found suitable for the MR environment.
    2. Gamma Irradiation Sterilization Validation (for implants):

      • Method: Selecting and substantiating a 25 kGy dose using method VDmax25, according to ISO 11137-1 and ISO 11137-2.
      • Acceptance Criteria: Sterility Assurance Level (SAL) of $10^{-6}$.
      • Outcome: Analysis showed the subject device implants met the SAL and did not create a new worst case compared to predicate device K212538.
    3. Bacterial Endotoxin Testing:

      • Method: Limulus amebocyte lysate (LAL) testing according to ANSI/AAMI ST72.

    Intended Use

    DESS Dental Smart Solutions abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for prosthetic restorations.

    All digitally designed custom abutments for use with DESS Ti Base abutments or Pre-Milled Blank abutments are to be sent to a Terrats Medical validated milling center for manufacture.

    Device Description

    The purpose of this submission is to add components to the DESS Dental Smart Solutions system, which includes dental implants, abutments, and prosthetic components cleared previously in various submissions. The previously cleared abutments and prosthetic components are compatible with a variety of original equipment manufacturer (OEM) dental implants as well as DESS Dental Smart Solutions dental implants.

    This submission adds various abutments to the DESS and OEM implant lines as summarized on the following pages in Table 1 Summary of Subject Device Abutment Designs, and Table 2 Summary of Subject Device Abutment Sizes.

    The subject device abutment designs include Cover Screws, Healing Abutments, Temporary Abutments, Ti Base Abutments, AURUM Base Abutments (Ti Base abutments with a screw channel design that allows easier instrument access to the abutment screw), CoCr Base Abutments, Pre-Milled Blank Abutments, Multi-Unit Abutments (straight and angled), DESSLoc Abutments (Locator-type abutments), and abutment screws.

    AI/ML Overview

    This document is a 510(k) summary for the DESS Dental Smart Solutions, a line of endosseous dental implant abutments. It details the device's characteristics, intended use, and a comparison to predicate devices to establish substantial equivalence.

    Based on the provided text, the device itself is a physical medical device (dental implant abutments and associated components), not a software or AI-driven system. Therefore, the questions related to AI acceptance criteria, training/test sets, expert adjudication, MRMC studies, and ground truth establishment for AI would not be directly applicable to this product as described.

    The document focuses on establishing substantial equivalence to previously cleared predicate devices through:

    • Identical Intended Use: The device is intended for "functional and esthetic rehabilitation of the edentulous mandible or maxilla" by providing support for prosthetic restorations, which is the same as the predicate devices.
    • Similar Technological Characteristics: The device utilizes similar designs, materials (Ti-6Al-4V, Co-Cr-Mo alloy), manufacturing processes, and sterilization methods as its predicates.
    • Performance Data: Non-clinical testing (mechanical testing per ISO 14801, MR environment assessment) and comparison to existing data from predicate devices are used to demonstrate safety and effectiveness.

    Therefore, many of the requested elements for describing AI acceptance criteria and studies are not present or applicable in this document.

    However, I can extract information relevant to the device's performance assessment and criteria for its type of submission.

    Here's an attempt to answer the questions based solely on the provided text, acknowledging that the nature of the device (a physical implant component) means many AI-specific questions will be answered as "Not Applicable" (N/A):

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

    The document does not explicitly state quantifiable "acceptance criteria" in a table format with corresponding "reported device performance" metrics for this specific 510(k) submission. Instead, it relies on demonstrating substantial equivalence to existing predicate devices.

    The underlying "acceptance criteria" for demonstrating substantial equivalence for this device type are primarily through:

    • Mechanical Testing (ISO 14801): This is a critical performance standard for dental implants and abutments. The document states that mechanical testing was "conducted according to ISO 14801 to support the performance." The acceptance criteria would be successful completion of these tests, demonstrating the device's mechanical strength and fatigue resistance are comparable to or better than predicate devices. The reported performance is simply that the tests supported the performance.
    • Material Conformance: Materials must conform to specific ASTM standards (e.g., ASTM F136 for Ti-6Al-4V, ASTM F1537 for Co-Cr-Mo). The reported performance is that the materials conform to these standards.
    • Biocompatibility: While not detailed in this excerpt, the mention of "biocompatibility" in relation to predicates implies conformance to relevant biocompatibility standards (e.g., ISO 10993 series). The reported performance is that it is compatible.
    • Sterilization Validation: Demonstrated sterility assurance level (SAL) of 10⁻⁶ via validated methods (moist heat or gamma irradiation). The reported performance is that validation was performed and met this SAL.
    • Dimensional Compatibility: The abutments must fit the corresponding OEM implants correctly. The reported performance is that reverse engineering dimensional analysis confirmed compatibility.

    Due to the nature of the document being a 510(k) summary focusing on substantial equivalence rather than a full study report, specific numerical performance results for the device tests are not provided in this text.

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

    • Sample Size for Mechanical Testing: The document states "mechanical testing conducted according to ISO 14801." For such tests, ISO 14801 typically specifies minimum sample sizes (e.g., 10-11 samples for static strength, typically more for fatigue). The exact number of samples used for this specific submission is not explicitly stated, but it would have followed the standard's requirements.
    • Data Provenance: The mechanical testing and material analyses are assumed to be "non-clinical data submitted or referenced" by the manufacturer, Terrats Medical SL, based in Barcelona, Spain. The "reverse engineering dimensional analysis" was done by Terrats Medical SL or through contractual agreement. This is prospective testing performed to support the 510(k). The document itself does not specify the country of origin for the underlying OEM implant data used for reverse engineering, although the OEM companies are listed (e.g., Astra Tech AB, BioHorizons).

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

    N/A. This is a physical device. Ground truth, in the context of AI, refers to validated labels for data used to train and test an algorithm. For a physical device, performance is evaluated through engineering and biocompatibility testing against defined standards. There are no "experts" establishing ground truth in the AI sense. Testing would be performed by qualified engineers and technicians.

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

    N/A. Adjudication methods are typically used in clinical studies involving interpretation (e.g., by radiologists) to resolve discrepancies. This document describes non-clinical performance testing of a physical device.

    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

    N/A. This product is a dental implant abutment, not an AI software intended to assist human readers.

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

    N/A. This is a physical device, not an algorithm.

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

    N/A. For engineering tests of physical devices, the "ground truth" is typically derived from established engineering principles, international standards (e.g., ISO 14801 for mechanical properties, ASTM for materials), and the physical properties of the materials and designs themselves. There isn't "expert consensus" or "pathology" in the AI or clinical trials sense.

    8. The sample size for the training set

    N/A. This is a physical device; there's no "training set" in the machine learning sense. The device is manufactured based on established engineering designs and material specifications.

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

    N/A. No training set for AI. For device manufacturing, the "ground truth" for design and production parameters comes from established engineering best practices, prior successful device designs (predicate devices), and adherence to quality systems regulations (21 CFR Part 820).

    Intended Use

    DESS Dental Smart Solutions abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for prosthetic restorations.

    Device Description

    The purpose of this submission is to expand the DESS Dental Smart Solutions abutment system by a change in sterilization status to provide products sterile to the end user that were previously cleared to be provided non-sterile. The subject device abutments and abutment screws were cleared previously to be provided non-sterile to the end user in K170588, K191986, K212628, and K22288. All subject device components will now be provided sterile.

    The subject device components include Healing Abutments, Multi-Unit Abutments (0, 17°, and 30°), and abutment screws.

    AI/ML Overview

    The provided text is a 510(k) summary for the DESS Dental Smart Solutions, an endosseous dental implant abutment. It details the device, its intended use, and its substantial equivalence to previously cleared predicate and reference devices. However, this document does not contain the acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML medical device.

    The 510(k) submission for this dental abutment focuses on establishing substantial equivalence based on:

    • Design and Material: The subject device components are identical in design, material (Ti-6Al-4V alloy, DLC coating), and technological characteristics to previously cleared devices.
    • Manufacturing: The manufacturing process is consistent with previously cleared devices.
    • Biocompatibility: Referenced from previous K-clearances.
    • Sterilization: The main change in this submission is expanding the system to provide products sterile to the end-user via gamma irradiation, which was validated by referencing a previous K-clearance (K212538).
    • MR Environment Testing: Non-clinical analysis was performed to evaluate the subject devices in the MR environment, referencing published literature and FDA guidance.
    • Shelf Life Testing: Referenced from a previous K-clearance (K212538) for samples after accelerated aging.

    Therefore, I cannot fulfill your request to describe the acceptance criteria and a study proving an AI/ML device meets them based on the provided text, as this document is not about an AI/ML medical device. It's about dental implant abutments and establishes substantial equivalence through non-clinical performance data and comparison to predicate devices, not through AI/ML performance metrics.

    To provide the information you requested, I would need a document detailing the validation of an AI/ML medical device, which would include definitions of acceptance criteria (e.g., accuracy, sensitivity, specificity), details of training and test datasets, ground truth establishment, and potentially clinical effectiveness studies if applicable.

    Device Description

    MIST IC from Imagine Milling Technologies, LLC is a line of Ti-base and machinable blank abutments to interface with compatible dental implants from 3 manufacturers, a total of 14 implant-abutment interface compatibilities. The compatible implant body diameters range from 3.25 mm to 6.0 mm and the corresponding implant platform diameters range from 3.4 mm. The subject device prosthetic platform diameters range from 3.8 mm. All stock subject device components (abutments and abutment screws) are made of titanium alloy conforming to ASTM F136. The subject device MIST IC L-LINK abutments have a TiN coating achieved through a physical vapor deposition (PVD) process that is identical to the process used for TiN coating of Imagine Milling Technologies, LLC devices cleared in K 182246. The PVD cathodic arc evaporation process is a high current, low voltage process in which material evaporated from the cathode (Ti) is ionized, transported through the vacuum chamber with reactive gas (N2) and deposited as a non-porous, thin film on the titanium substrate.

    Each abutment is supplied with the non-sterile abutment screw designed for attachment to the corresponding compatible OEM implant.

    All patient-specific abutment fabrication for all MIST IC abutments is by prescription on the order of the clinician. All MIST IC abutments are intended to be milled at an Imagine Milling Technologies, LLC validated milling center under FDA quality system regulations.

    MIST IC L-LINK abutments are two-piece abutments to be used as a base when fabricating a CAD-CAM customized restoration where the superstructure produced will compose the second part of the two-piece abutment; the assembly becoming a final finished medical device after cementation on the subject device abutment. They are provided in straight designs, with engaging and non-engaging connections. The L-LNK abutments and corresponding zirconia superstructure are provided to the clinician either with the superstructure cemented to the abutment by the dental laboratory, or separately for the clinician to bond together chairside using the cement recommended in the labeling (RelyX RMGIP bonding cement, cleared in K022476).

    Design parameters for the L-LINK zirconia superstructure are: Minimum wall thickness - 0.5 mm Minimum post height for single-unit restoration - 4.0 mm Minimum gingival height of the coping - 0 mm (all L-LINK bases have minimum gingival height of 0.5 mm) Maximum gingival height – 5.0 mm Maximum angle - 20°

    All zirconia copings (superstructures) for use with the subject device MIST IC L-LINK abutments will conform to ISO 13356.

    MIST IC PREFIT abutments are cylindrical abutments designed for patient-specific abutment fabrication by a CAD-CAM process and machined into a one-piece, all titanium abutment. The portion of the abutment available for milling is either 9.9 mm in diameter by 20 mm in diameter by 20 mm in diameter by 20 mm in length. MIST IC PREFIT abutments have an engaging connection.

    Design parameters for the PREFIT patient specific abutment are: Minimum wall thickness - 0.5 mm Minimum post height for single-unit restoration - 4.0 mm Minimum gingival height - 0.5 mm Maximum gingival height - 5.0 mm Maximum angle - 30°

    AI/ML Overview

    The provided text describes the regulatory clearance of a dental device, "MIST IC." It outlines the device's intended use and compares it to a predicate device. However, it does not contain explicit information about acceptance criteria or a specific study proving the device meets those criteria, especially in the context of AI performance.

    This document focuses on establishing substantial equivalence for regulatory purposes, relying heavily on non-clinical testing and comparison to an existing predicate device. The information provided is primarily relevant to the safety and mechanical performance of the dental implant abutments, not AI/algorithm performance.

    Therefore, many of the requested fields cannot be directly answered from the provided text.

    Here's a breakdown of what can and cannot be extracted from the document based on your request:


    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly state acceptance criteria in terms of numerical thresholds or performance metrics for an AI algorithm. Instead, it lists non-clinical tests performed to demonstrate substantial equivalence to the predicate device and ensure safety and efficacy.

    CompatibilityReverse engineering of OEM implant bodies, OEM abutments, and OEM abutment screwsConfirmed compatibility for each of the compatible OEM implant system interfaces

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

    This information is not provided in the document. The document refers to "non-clinical testing data" but does not detail the sample sizes for these tests or the provenance of any data beyond indicating it's for dental implant abutment compatibility and mechanical strength. There is no mention of an "AI test set."

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

    This information is not provided. The document describes mechanical performance and material compatibility testing, not a study requiring expert-established ground truth for an AI algorithm.

    4. Adjudication Method for the Test Set

    This information is not provided. As no "test set" for AI or expert review is mentioned, adjudication methods are not applicable here.

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

    No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The document explicitly states: "No clinical data were included in this submission." This type of study typically involves human readers and is clinical in nature.

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

    The document describes a physical medical device (dental implant abutments) and its mechanical and material properties. There is no mention of an AI algorithm or standalone algorithm performance.

    7. The Type of Ground Truth Used

    For the non-clinical tests mentioned, the "ground truth" is established by objective engineering standards and validated testing protocols (e.g., ISO 14801 for mechanical testing, ISO 10993 for biocompatibility). There is no "expert consensus," "pathology," or "outcomes data" as ground truth for an AI in this context.

    8. The Sample Size for the Training Set

    This information is not provided. There is no mention of a training set as the document does not concern an AI algorithm.

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

    This information is not provided as there is no mention of a training set or AI algorithm in the provided text.


    Summary of what the document IS about:

    The document is an FDA 510(k) clearance letter for the MIST IC dental abutment. It establishes substantial equivalence to a predicate device (K182246) based on:

    • Non-clinical testing: Biocompatibility, sterilization, MR compatibility, reverse engineering for compatibility, and static/dynamic compression-bending.
    • Material properties: Both subject and predicate devices are made of Titanium Alloy (ASTM F136), with TiN coating for L-LINK abutments, and use zirconia copings (ISO 13356) and the same bonding cement (RelyX RMGIP).
    • Design similarities: Similar CAD-CAM fabrication process, restoration types (single/multi-unit, cement-retained), and design parameters (minimum wall thickness, post height, gingival height, angulation).
    • Intended Use: Supports a prosthetic device in partially or completely edentulous patients, compatible with various specified implant systems.

    The text does not discuss, describe, or evaluate any AI component of the device.

    Intended Use

    Duranext Abutments are intended for use with dental implants as a support for single or multiple toth prostheses in the maxilla or mandible of a partially or fully edentulous patient.

    Device Description

    Duranext Abutments from Elegant Direct Corp. are a line of machinable blanks incorporating interface features compatible with eleven (11) endosseous dental implant system platforms (three (3) designs from two (2) manufacturers) and intended to be milled at an Elegant Direct Corp. validated milling center to produce patient-specific dental implant abutments. The subject device platform diameters range from 3.0 mm to 6.0 mm, and the corresponding compatible implant body diameters range from 3.0 mm to 6.0 mm.

    Duranext Abutments are designed for fabrication of custom titanium alloy dental implant abutments by a CAD/CAM process. All patient-specific custom abutment fabrication is by prescription on the order of the clinician. The portion of each abutment available for milling is 9.5 mm in diameter and 20 mm long. The apical end is premanufactured to fit the compatible implant platform, as shown above, and is available in an engaging (anti-rotation) design. A feature at the coronal end of the abutment is provided to interface with the milling equipment. Each abutment is provided with a screw designed to fit the compatible implant. The patient-specific abutment is intended to support a cement-retained single crown or multi-unit restoration.

    AI/ML Overview

    The provided document is a 510(k) summary for the Duranext Abutments, a dental device. It does not describe a study involving an AI algorithm or human-in-the-loop performance. Therefore, I cannot extract the information required for questions about AI performance, multi-reader multi-case studies, or specific details of ground truth establishment for AI training/testing.

    However, I can provide information about the acceptance criteria and the non-clinical study that proves the device meets those criteria, as well as general device information.

    Here's what can be extracted based on the document:

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

    The document does not explicitly present a table of "acceptance criteria" in the format of a diagnostic test (e.g., sensitivity, specificity). Instead, substantial equivalence is claimed based on performance testing and comparison to predicate devices for mechanical properties, biocompatibility, and sterilization. The acceptance criteria are implicitly met by successful completion of these tests in accordance with relevant ISO standards.

    Acceptance Criterion (implicitly met by standard)Reported Device Performance (Summary)
    SterilizationSterilization according to ISO 17665-1 (demonstrated readiness for sterilization)
    BiocompatibilityBiocompatibility according to ISO 10993-12 (for general requirements), and specifically ISO 10993-5 (cytotoxicity)
    Compatibility with OEM ImplantsReverse engineering of OEM implant bodies, OEM abutments, and OEM abutment screws (confirmed compatibility)
    Mechanical Strength / Dynamic FatigueStatic compression and compression fatigue testing according to ISO 14801 (sufficient strength for intended use)
    Design Parameters (for CAD/CAM abutments)Minimum wall thickness: 0.5 mm
    Minimum post height: 4.0 mm
    Maximum abutment height from prosthetic platform: 20.0 mm
    Maximum gingival height: 4.0 mm
    Minimum gingival height: 0.5 mm
    Angulation: 0° to 30°

    2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

    The document does not mention "test sets" in the context of diagnostic data. The "testing" refers to non-clinical performance testing of the physical abutment blanks. The sample sizes for these specific engineering tests (e.g., number of abutments tested for fatigue) are not provided in this summary. The provenance is implied to be from the manufacturer's testing or a contracted lab.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

    Not applicable, as this is a physical medical device (dental abutment) and the evaluation is based on non-clinical performance testing against engineering standards, not diagnostic interpretation by experts.

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

    Not applicable. Adjudication methods like 2+1 or 3+1 are used for establishing ground truth in diagnostic studies, which is not what this document describes.

    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 dental abutment, not an AI-powered diagnostic tool. No MRMC study was conducted.

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

    Not applicable. This device is not an algorithm.

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

    The "ground truth" for this device's performance is established by engineering standards and physical measurements. For example:

    • Biocompatibility: Established by adherence to ISO 10993 series standards, which involves methods like cytotoxicity testing.
    • Mechanical Strength: Established by dynamic fatigue testing according to ISO 14801, which defines acceptable load cycles and failure modes.
    • Dimensional Compatibility: Established by reverse engineering and direct measurement against OEM specifications.

    8. The sample size for the training set

    Not applicable. This device is not an AI algorithm, so there is no training set in the context of machine learning.

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

    Not applicable. As above, there is no training set. The "ground truth" for the device's design and manufacturing parameters is established via engineering specifications, material properties, and adherence to relevant ISO standards, rather than a labeled dataset.

    Device Description

    The Panthera Dental Milled Bar is a metallic dental restorative device that is intended for attaching by screw retention to dental implants to aid in the treatment of partial and totally edentulous patients for the purpose of restoring chewing function.

    The Panthera Dental milled bars for which clearance is requested, are included in one of the following bar types, which have distinct design specifications.

    The Type I bars are specific for removable overdenture and include:

    • . Panthera Dental Dolder Bar, Hader Bar, Milled Bar, REBourke Bar and Paris Bar.

    The Type II bars are specific for fixed prostheses and include:

    • Panthera Dental Wrap-around Bar, Montreal Bar, Montreal Bar with metallic lingual, Pin Lingual Bar and Pin Wrap-Around Bar.

    The Panthera Dental Milled Bar is designed to match an individual patient. Panthera Dental designs the bar from a three-dimensional optical and/or digital scanner system that scans the patient's impression; the dental professional prepares the model cast beforehand. The designed bar is then machined using a computer-aided design/ computer-aided manufacturing (CAD/CAM) software system. The bar is milled from titanium (Ti-6AI-4V grade 5). CAD/CAM fabrication is only performed by Panthera Dental, within our manufacturing control and not by the dental laboratory.

    The Panthera Dental Milled Bar is packaged as non-sterile, and delivered to a dental laboratory for completion. Once received at the laboratory, the Panthera Dental Milled Bar is matched to a denture for final placement. The Panthera Dental Milled Bar provides retention and support for a removable or fixed denture made of standard laboratory dental materials such as resin composite.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and the study information for the Panthera Dental Milled Bars, based on the provided document.

    1. Table of Acceptance Criteria and Reported Device Performance

    The document doesn't explicitly present acceptance criteria in a tabular format with specific numerical targets. Instead, it describes performance through compliance with recognized standards and successful testing outcomes. The "performance" is primarily demonstrated through meeting mechanical strength requirements and biocompatibility standards, and by showing substantial equivalence to a predicate device.

    Acceptance Criteria CategoryDescription of Criteria (Implied)Reported Device Performance
    Mechanical StrengthMeets the requirements for dynamic fatigue testing for endosseous dental implants.The device (bar and cylinders) has the mechanical strength for its intended clinical application, as demonstrated by fatigue testing according to ISO 14801 and FDA guidance.
    BiocompatibilityBiocompatible with tissue/bone/dentin for long-term contact.Made from Titanium Ti-6Al-4V, a material used in the predicate. Cytotoxicity, extractable/leachable, toxicological risk assessment, and bacterial endotoxin testing compliant with ISO 10993-1, ISO 10993-5, ISO 10993-12, ANSI/AAMI ST72, and USP .
    SterilizationCan be effectively sterilized to a Sterility Assurance Level (SAL) of 10^-6.Sterilization validation (Pre-vacuum steam sterilization) for the primary predicate was successful, demonstrating an SAL of at least 10^-6. The proposed device uses the same materials and sterilization cycle, therefore no additional testing was required.
    Design Accuracy/FitEnsures a perfect fit and proper seating with compatible implant systems, with no possible interference.Reverse engineering (RE) confirmed that the critical parameters of the design for interface connection, including tolerance limits, fall within the measured sizes of the Nobel Biocare counterparts.
    Manufacturing ReliabilityManufacturing process is reliable and produces consistent results.A process capability study conducted for the primary predicate (K173466) is valid for the proposed device, as the manufacturing process is identical.

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

    • Sample Size for Test Set: The document does not specify the exact sample size for each test (e.g., how many bars were subjected to fatigue testing). It refers to "the bar itself" and "the bar cylinders" for fatigue testing. For reverse engineering, it mentions "each interface connection" and "each components per size and type" which implies multiple samples were analyzed to determine critical parameters and tolerance limits.
    • Data Provenance: The document does not specify country of origin for data. The non-clinical testing was conducted by Panthera Dental Inc., a Canadian company. The tests are framed within the context of a 510(k) submission to the U.S. FDA. The testing conducted was for the primary predicate device (K173466) and determined to be applicable to the proposed device due to identical materials and manufacturing processes. The tests were retrospective in the sense that they were done on manufactured devices/components.

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

    • Number of Experts: This information is not explicitly stated. The document refers to compliance with ISO and FDA guidance documents for testing, which implies a standard methodology rather than expert consensus on a subjective test set.
    • Qualifications of Experts: Not specified. Testing was performed by Panthera Dental Inc. or their designated testing facilities to meet recognized standards.

    4. Adjudication Method for the Test Set

    Not applicable. The tests mentioned (fatigue, biocompatibility, sterilization, reverse engineering, process capability) are objective physical, chemical, and mechanical tests, not subjective evaluations requiring adjudication.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The Panthera Dental Milled Bars are a physical dental device, not an AI or imaging diagnostic tool that would typically involve a reader study.

    6. Standalone (Algorithm Only) Performance Study

    Not applicable. This is a physical medical device, not an algorithm or software. The mention of CAD/CAM refers to the design and manufacturing process, not an independent algorithm performance.

    7. Type of Ground Truth Used

    The "ground truth" for the device's performance is established through:

    • Compliance with recognized standards: ISO 14801 for fatigue testing, ISO 10993 series and USP for biocompatibility, and ANSI/AAMI-ST8 for sterilization.
    • Measurement and verification: Reverse engineering to ensure precise fit with implant systems.
    • Predicate device equivalence: Performance data for the predicate device (K173466) is directly applied due to identical materials, design principles, and manufacturing processes.

    8. Sample Size for the Training Set

    Not applicable. This is a physical medical device. There is no "training set" in the context of machine learning or AI. The design and manufacturing processes are established based on engineering principles and validated through testing.

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

    Not applicable, as there is no "training set" in the context of this device. The design specifications and manufacturing parameters are established through engineering design, material science, and testing against industry standards, not via a machine learning training process.
