    Intended Use

    The SFI-Bar® Implant Abutments are indicated to be used with dental implants as a prosthetic framework to support and /or retain removable dental prostheses in the treatment of partially or totally edentulous patients to restore chewing function. The abutment screws are intended to secure the bar to the endosseous implants.

    Device Description

    The SFI Bar® Implant Abutments provide the connection between compatible dental implant systems for the fixation of removable overdentures. The SFI Bar® Implant Abutments consist of an abutment, which is attached to a stress free bar for the fixation of removable overdentures. The implant abutment is screwed into the dental abutment.

    The implant abutments fit Straumann Bone Level RP, Straumann Bone Level NP, Ankylos, Nobel 5mm Trilobe, Nobel Conical RP, Nobel Conical NP, Astra 4.5/5.0, Astra 3.5/4.0, Zimmer TSV 5.7mm.

    There are nine (9) different platforms and each platform is compatible with one or more implant types. The platforms of the abutments are [BD], [BE], [AE], [AN], [AY], [AY], [AJ], [AK], [BF]. Table 1 indicates which implants are compatible with these platforms. The difference between each platform is the internal connection with the specific implant.

    The devices are supplied non-sterile, therefore there is no shelf life.

    AI/ML Overview

    The provided document is a 510(k) Premarket Notification for the SFI Bar® Implant Abutments. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving the safety and effectiveness of a novel device through extensive clinical trials with specific acceptance criteria and detailed performance metrics.

    Therefore, many of the requested categories for device performance, ground truth, and comprehensive study details are not applicable or available in this type of regulatory submission. The document primarily describes non-clinical testing to support the claim of equivalence.

    Here's a breakdown based on the available information:

    1. Table of acceptance criteria and the reported device performance

    Acceptance CriteriaReported Device Performance
    Material Conformance: Material of implant abutments conforms to ASTM F136, Wrought Titanium 6 Aluminum-4 Vanadium ELI Alloy.The material of the implant abutments conform to ASTM F136, Wrought Titanium 6 Aluminum-4 Vanadium ELI Alloy.
    Performance Equivalence: Device performs equivalently to predicate SFI Bar® Implant Abutments.Testing has shown that the SFI-Bar® Implant Abutments included in this application are equivalent in performance characteristics to the predicate SFI Bar®. The acceptance criteria were met. (Specific numerical performance criteria are not detailed in the document.)
    Design and Manufacturing: Designed and developed, and manufactured according to manufacturer's specifications and controlled procedures. Validation protocol done in accordance with Design Control requirements per FDA CFR820.30.The implant abutments were designed and developed, and manufactured according to manufacturer's specifications and controlled procedures. A validation protocol was done in accordance with Design Control requirements per FDA CFR820.30.
    Non-clinical Test Methods: Application and functional testing done using the same test methods as in predicate devices.The test methods used were the same as in predicate devices.
    Worst-Case Sample Identification: Tolerance analysis of platforms performed to identify worst-case test samples.Tolerance analysis of platforms -to-identify-worst-case-test-samples was performed.

    Torque Tests, Application and Functional Tests: Performed as part of non-clinical testing.Torque tests, application and functional tests have been carried out.

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

    • Sample Size: Not explicitly stated as numerical counts of products tested. The document mentions "tolerance analysis of platforms -to-identify-worst-case-test-samples" which implies selected samples were tested, but the exact number isn't provided.
    • Data Provenance: Not specified. Given it's a US-based company submitting to the FDA, it's highly probable the testing was conducted in the US, but this is not explicitly stated. The testing is described as non-clinical, likely laboratory-based.
    • Retrospective or Prospective: Not applicable, as this refers to clinical studies, and only non-clinical testing was performed.

    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)

    • Number of Experts & Qualifications: Not applicable. Non-clinical testing for equivalence does not typically involve expert consensus to establish a "ground truth" in the way clinical studies do. The "ground truth" for material specifications and performance would be established by engineering standards and internal company specifications.

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

    • Adjudication Method: Not applicable. This concept is relevant to clinical studies involving human interpretation or subjective assessments. Performance testing of abutments involves objective measurements against engineering specifications.

    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

    • MRMC Comparative Effectiveness Study: No, this type of study was not done. The device is a dental implant abutment, not an AI-powered diagnostic tool.
    • Effect Size: Not applicable.

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

    • Standalone Performance: Not applicable. The device is a mechanical component (dental abutment), not an algorithm.

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

    • Type of Ground Truth: For the non-clinical testing, the "ground truth" would be engineering specifications, material standards (like ASTM F136), and validated test methodologies to assess physical properties and fit. There is no biological "ground truth" in the context of this 510(k) submission.

    8. The sample size for the training set

    • Sample Size for Training Set: Not applicable. The device is a manufactured medical device, not an AI/ML model that requires a training set.

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

    • Ground Truth for Training Set Establishment: Not applicable.

    Intended Use

    The SFI-Bar® is intended to be used with the implant manufacturer's implant (Table 1) to provide support for fixation of overdentures.

    Device Description

    The SFI-Bar® provides the connection between compatible dental implant systems for the fixation of removable overdentures. The SFI-Bar@ consists of an implant adapter (abutinent) and a stress-free bar for the fixation of removable overdentures. The implant adapter is screwed into the dental implant.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and study information for the SFI-Bar® based on the provided text:

    Acceptance Criteria (Performance Characteristics)Reported Device Performance
    Torque testsMet acceptance criteria
    Application testingMet acceptance criteria
    Functional testingMet acceptance criteria
    Performance equivalence to predicate SFI-Bar®Equivalent

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

    The document does not explicitly state a separate "test set" and its sample size in the context of clinical data for the SFI-Bar®. The performance evaluation relies on non-clinical test data.

    Data Provenance: The testing was conducted as part of a 510(k) submission, originating from Switzerland (Cendres + Métaux SA, Biel/Bienne, Switzerland). The data is retrospective in the sense that it's an evaluation against established performance metrics and comparison to predicate devices, rather than a prospective clinical trial.

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

    This information is not provided as the ground truth for this device's performance evaluation was based on engineering and performance testing rather than expert-derived clinical ground truth.

    4. Adjudication Method for the Test Set

    This information is not applicable as the evaluation did not involve human interpretation or adjudication processes like those in clinical image analysis studies. The adjudication for performance was based on meeting technical specifications from engineering tests.

    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

    No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for AI-powered diagnostic devices, which is not the nature of the SFI-Bar®.

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

    This concept is not applicable to the SFI-Bar®. The device is a physical dental abutment, not an algorithm. The performance evaluation was of the physical device's mechanical properties and function.

    7. The Type of Ground Truth Used

    The ground truth for evaluating the SFI-Bar®'s performance was based on:

    • Engineering specifications and standards: Adherence to established mechanical properties (e.g., torque, application, functional requirements).
    • Performance characteristics of predicate devices: The SFI-Bar® was compared for substantial equivalence to legally marketed predicate devices, meaning their established safe and effective performance served as a benchmark.

    8. The Sample Size for the Training Set

    This information is not applicable. The SFI-Bar® is a physical medical device, not an AI/ML algorithm that requires a "training set."

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

    This information is not applicable as there is no "training set" for this device.

    Intended Use

    The SFI-Bar® is intended to be used with the implant manufacturer's implant (TABLE a) to provide support for fixation of overentures.

    Device Description

    The SFI-Bar® provides the connection between compatible dental implant systems for the fixation of removable overdentures. The SFI-Bar® consists of an implant adapter (abutment) and a stress-free bar for the fixation of removable overdentures. The implant adapter is screwed into the dental implant.

    AI/ML Overview

    Here's an analysis of the provided text to extract information about acceptance criteria and the study proving compliance for the SFI-Bar® device:

    The provided document describes the 510(k) premarket notification for the SFI-Bar® device, a dental implant abutment. It seeks to establish substantial equivalence to predicate devices, rather than proving performance against novel acceptance criteria in a comprehensive clinical study.

    1. Table of Acceptance Criteria and Reported Device Performance

    The submission states that the SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar® and that acceptance criteria were met. However, the document does not explicitly list specific numerical acceptance criteria for performance metrics. Instead, it relies on demonstrating equivalence to the predicate device.

    The "Performance Data" section mentions:

    • Validation of Sterilization for metallic components.
    • Evaluation of the intended manual disinfection procedure with SFI-Bar® Retention inserts G.
    • Application and functional testing based on literature research.

    The key acceptance criterion seems to be: "The SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar®."

    Acceptance Criteria (Implied)Reported Device Performance
    Sterilization validated for metallic components.Validation of Sterilization has been conducted.
    Intended manual disinfection procedure evaluated.Evaluation of the intended manual disinfection procedure with SFI-Bar® Retention inserts G. has been conducted.
    Application and functional testing consistent with predicate.Application and functional testing based on literature research have been conducted. The test methods used were the same as in the predicate device.
    Overall performance equivalent to the predicate SFI-Bar®.Testing has shown that the SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar®.
    Device is safe and effective for its intended use.The summary of technological characteristics indicates that the device is safe and effective for its intended use and performs as well or better than the predicate devices.
    Ability to provide support for fixation of overdentures with compatible implant systems.The SFI-Bar® is intended to be used with the implant manufacturer's (TABLE A) implant to provide support for fixation of overdentures. (Supported by technical compatibility and material equivalence.)

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

    The document explicitly states: "Non-clinical test data was used to support the substantially equivalence claim. Clinical testing was not necessary."

    This indicates that a "test set" in the sense of a patient cohort or a large sample for a clinical trial was not used for this submission. The testing performed was non-clinical.

    • Sample Size for Test Set: Not applicable in the context of clinical or large-scale performance testing. The "test samples" mentioned in the context of "analysis of platforms to identify worst-case test samples" would likely refer to physical samples or configurations chosen for non-clinical engineering tests (e.g., sterilization, disinfection). The specific number of these non-clinical worst-case samples is not provided.
    • Data Provenance: The submission is from Cendres+Metaux SA, Biel/Bienne, Switzerland. The non-clinical testing was conducted by the manufacturer, but the location where the tests were performed is not specified. The data is retrospective in the sense that it's based on existing designs and literature, and performed prior to this submission for regulatory clearance.

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

    Not applicable. As clinical testing was not performed and the submission relies on demonstrating substantial equivalence through non-clinical data and comparison to predicate devices, there was no "ground truth" to be established by experts in a clinical context for a test set. The validation and evaluation mentioned primarily concern manufacturing processes and materials.

    4. Adjudication Method for the Test Set

    Not applicable, as no clinical test set requiring expert adjudication was used.

    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 implant abutment, a physical medical device, not an AI or imaging diagnostic tool. Therefore, MRMC studies and AI assistance are irrelevant to this submission.

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

    Not applicable. This is a physical medical device, not an algorithm or software.

    7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)

    Given the nature of the device and the submission, the "ground truth" relied upon is primarily:

    • Engineering and material standards (e.g., ASTM F 136 for Titanium alloy).
    • Performance characteristics of legally marketed predicate devices (K073628, K083876, K102382) as established through their prior regulatory clearances.
    • Scientific literature research supporting application and functional principles.
    • Validation of manufacturing processes (sterilization, cleaning).

    There isn't "ground truth" in the sense of clinical outcomes or expert consensus on diagnostic interpretations.

    8. The Sample Size for the Training Set

    Not applicable. This is not an AI/machine learning device that requires a training set.

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

    Not applicable. As there is no training set, there is no ground truth establishment for it.

    In summary: The submission for the SFI-Bar® focuses on demonstrating substantial equivalence to existing predicate devices, leveraging non-clinical testing, material standards, and literature review. It does not involve new clinical trials, expert consensus, or AI performance metrics.

    Device Description

    The SFI-Bar® provides the connection between compatible dental implant systems for the fixation of removable overdentures. The SFI-Bar® consists of an implant adapter (abutment) and a stress-free bar for the fixation of removable overdentures. The implant adapter is screwed into the dental implant.

    AI/ML Overview

    The provided text describes a 510(k) submission for the SFI-Bar® Abutment, a dental device. The document primarily focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing. Here's a breakdown of the requested information based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly list specific numerical acceptance criteria for each test. Instead, it states that "The acceptance criteria were met" and that the "SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar®." The performance characteristics evaluated are generally described.

    Acceptance Criteria (Implied)Reported Device Performance
    Equivalent performance characteristics to the predicate SFI-Bar®"Testing has shown that the SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar®." This equivalence is established through:
    (Specific torque values for mechanical stability not explicitly stated)Torque tests: Conducted to evaluate performance characteristics. The methods used were the same as in the predicate device. The device was found to be equivalent in performance.
    (Specific functional criteria not explicitly stated)Application testing: Conducted to evaluate performance characteristics. The methods used were the same as in the predicate device. The device was found to be equivalent in performance.
    (Specific functional criteria not explicitly stated)Functional testing: Conducted to evaluate performance characteristics. The methods used were the same as in the predicate device. The device was found to be equivalent in performance. Key functional characteristics mentioned (also shared with the predicate) include: primary splinting of implants, countering forces that would dislodge the denture, distribution of shear forces, resilience compensation, common cleaning procedures for patients, and common patient handling (cleaning and insertion of denture).
    (Shelf life performance equivalent to predicate)Shelf life: "95% after 10 years" (same as predicate device).
    (Manufacturing processes and materials equivalent to predicate)Packaging, materials and processes: "Produced on process orientated CNC machines. The last step is a validated cleaning process (same processes). Packaging: Dentalblister, non-sterile." The material is "Wrought Titanium-6Aluminium-4Vanadium ELI Alloy for Surgical Implant applications" conforming to ASTM F 136 (same as predicate).
    (Compatibility with specified implant systems)Compatibility: The SFI-Bar® Abutment is designed to connect with various dental implant systems from Thommen Medical, Neoss, and Institut Straumann (specifically listed in Table 1). The development and manufacturing were done "in close cooperation with the implant companies" with Quality Agreements in place (Design Control, Change Control, Complaint Handling, and Post Market Surveillance). This implies successful compatibility testing was conducted to ensure proper fit and function with these diverse implant systems, similar to the predicate device's compatibility.
    (Safety for intended use)"The summary of technological characteristics as well as the torque test, application and functional testing indicate that the device is safe and effective for its intended use and performs as well or better than the predicate devices." This is a general conclusion based on the non-clinical testing and comparison to the predicate, demonstrating that the device does not raise new questions of safety or effectiveness. This is the overarching "acceptance criterion" for a 510(k) submission seeking substantial equivalence.

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

    • Sample Size: The document does not specify the exact sample sizes used for the torque tests, application testing, or functional testing. It only states that these tests were conducted.
    • Data Provenance: The data is non-clinical test data. The country of origin of the data is not explicitly stated, but the applicant (Cendres+Métaux SA) is located in Switzerland. The testing was conducted to support a 510(k) submission to the FDA (USA). The study is retrospective in the sense that it relies on existing testing methodologies and comparisons to a previously cleared predicate device.

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

    This information is not applicable (N/A) as the study described is a non-clinical, bench testing study comparing the performance of a new device to a predicate device. There is no "ground truth" derived from expert review of cases or outcomes in a clinical context. The "ground truth" for the testing would be established by validated test methods and engineering specifications.

    4. Adjudication Method for the Test Set

    This information is not applicable (N/A) for the same reasons as point 3. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies involving interpretation of medical images or patient outcomes, not in bench testing of a dental implant abutment.

    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 (N/A). The device described, the SFI-Bar® Abutment, is a physical dental implant component, not an AI or imaging diagnostic device. Therefore, an MRMC study and AI assistance effect size are irrelevant to this submission.

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

    This information is not applicable (N/A). As mentioned in point 5, this is a physical dental device, not an algorithm.

    7. The Type of Ground Truth Used

    The "ground truth" for this type of non-clinical device testing is engineering specifications, validated test methods, and the performance characteristics of the legally marketed predicate device. The goal is to demonstrate that the candidate device performs "as well or better than" the predicate device under the same test conditions. There isn't an "expert consensus," "pathology," or "outcomes data" ground truth in the clinical sense for this specific evaluation. The "worst-case test samples" were identified through analysis of platforms, indicating an engineering-based approach to defining test parameters.

    8. The Sample Size for the Training Set

    This information is not applicable (N/A). There is no concept of a "training set" in the context of this non-clinical bench testing for a physical dental device. Training sets are relevant for machine learning algorithms or similar data-driven models.

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

    This information is not applicable (N/A), as there is no training set for this type of device submission.
