    Intended Use

    ARDS dental implants are indicated for use in surgical and restorative applications for placement in the bone of the upper and lower jaw to provide support for prosthetic devices in order to restore the patient's chewing function. ARDS dental implants are indicated for two-stage surgery.

    Device Description

    ARDS implants are made from Titanium alloy. The ARDS implants geometrical shape is characterized by altering drilling profile, with double thread at the upper part that change to one thread at the lower part, which increases its surface, and as a result, increases in the preliminary contact surface with the bone. The ARDS dental implants are : S type: Internal hex implants, length 10/13 mm, diameter 3.75/4.5 mm, with double thread at the upper part that goes over in a single thread at the lower part. S implant types are supplied sterile in a double vial system, inside a plastic box which includes the covering screw and the Instructions For Use. The abutments are for single use only and supplied non-sterile. The tools are reusable and supplied non-sterile, they must be sterilized by autoclave before use.

    AI/ML Overview

    The documents provided are FDA 510(k) clearance letters and related summaries for "ARDS Dental Implants." These documents establish that the device is "substantially equivalent" to a legally marketed predicate device.

    It is important to note that 510(k) clearance usually signifies a device is as safe and effective as a predicate device, but it does not typically involve specific acceptance criteria, comprehensive clinical studies, or performance metrics in the same way a PMA (Pre-Market Approval) or a more rigorous clinical trial for a novel device would. The focus of a 510(k) is on substantial equivalence.

    Therefore, based solely on the provided text, a detailed table of acceptance criteria and reported device performance, information on sample sizes for test sets, expert adjudication methods, MRMC studies, standalone performance, and detailed ground truth establishment methods as you've requested cannot be fully provided in the manner normally associated with studies proving discrete performance metrics for AI/ML devices.

    The information available primarily discusses the device's classification, intended use, and comparison to a predicate device.

    However, I can extract and infer some points based on the provided text:


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

    The documents do not provide a table of quantitative acceptance criteria or specific device performance metrics in terms of accuracy, sensitivity, specificity, etc., because this is a 510(k) summary for a dental implant, not an AI/ML device. The "performance" being assessed here is the substantial equivalence to a predicate device in terms of design, materials, and intended use.

    Acceptance Criterion (Implied by 510(k))Reported Device Performance (Implied by 510(k) Clearance)
    Substantial Equivalence to Predicate Device (Alpha Bio Dental Implant System K063364)ARDS Dental Implants are "substantially equivalent" in technology and intended use. Differences (proprietary in nature) do not raise additional safety or efficacy concerns.
    Intended UseIndicated for use in surgical and restorative applications for placement in the bone of the upper and lower jaw to provide support for prosthetic devices in order to restore the patient's chewing function and indicated for two-stage surgery.
    MaterialsMade from Titanium alloy.
    Sterility & Reusability of ComponentsS implant types are supplied sterile. Abutments are for single use only and supplied non-sterile. Tools are reusable and supplied non-sterile, requiring sterilization by autoclave before use.

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

    Not applicable. The clearance is based on comparison to a predicate device, not on a clinical test set in the traditional sense for evaluating an AI/ML diagnostic or prognostic device's performance metrics. The "testing results" mentioned in point 6 of K071803 refer to tests related to the proprietary differences and ensuring they don't impact safety/efficacy relative to the predicate, likely involving bench testing, material properties, and possibly limited in vitro or in vivo studies, but not a large-scale clinical test set for performance metrics.

    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. This is not a diagnostic device where expert ground truth is established for a test set.

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

    Not applicable.

    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 physical dental implant, not an AI/ML diagnostic or assistive device for human readers.

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

    Not applicable.

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

    The "ground truth" for this 510(k) clearance is primarily the established safety and effectiveness of the predicate device (Alpha Bio Dental Implant System, K063364) and the demonstration that the ARDS Dental Implants are substantially equivalent to it. This involves:

    • Physical and mechanical characteristic comparison (materials, geometry, dimensions).
    • Intended use comparison.
    • "Testing results" (mentioned in section 6 of K071803 summary) which likely refer to engineering, biocompatibility, and perhaps mechanical fatigue tests to support that the "proprietary" differences do not raise new safety or effectiveness concerns compared to the predicate.

    8. The sample size for the training set

    Not applicable. This is not an AI/ML device that uses a training set.

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

    Not applicable.
