AI/ML Overview

The provided text is a 510(k) summary for the OSSTEM Implant Co., Ltd.'s GS III Fixture System. It aims to demonstrate substantial equivalence to a predicate device, the HG II Fixture System (K080744).

However, the document does not contain acceptance criteria, device performance data, details of a study (like sample sizes, ground truth establishment, or expert qualifications), or multi-reader multi-case study information. It primarily focuses on the device's description, indications for use, comparison to a predicate device, and a general statement about safety, performance, and product validations being conducted.

Based on the provided text, I can only provide the following:

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

No specific acceptance criteria or quantitative performance measures are stated in the provided text. The submission aims to demonstrate substantial equivalence based on material, indication for use, and similar design and technological characteristics.

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

Not provided. The text does not describe any specific clinical or performance testing studies with sample sizes or data provenance. It only states that "Safety tests including biocompatibility have been performed to ensure the devices comply with the applicable International and US regulations."

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 provided. The document does not describe the establishment of a ground truth for any test set, nor does it mention any experts involved in such a process.

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

Not provided. There is no mention of an adjudication method as no test set or study details are given.

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, not an AI-powered diagnostic tool. Therefore, a multi-reader multi-case study comparing human readers with and without AI assistance is not relevant to this submission.

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

Not applicable. As stated above, this is a dental implant, not an algorithm.

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

Not provided. No study details are given that would involve establishing a ground truth. The submission relies on demonstrating substantial equivalence to a predicate device based on design, materials, and intended use, rather than detailed clinical outcome data from a novel study.

8. The sample size for the training set:

Not applicable. As this is a medical device (dental implant) and not a machine learning algorithm, there is no concept of a "training set" in the context of this 510(k) submission.

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

Not applicable. See point 8.

Regulation Number and Section

§ 872.3640 Endosseous dental implant.

(a)
Identification. An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.(b)
Classification. (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2)
Classification. Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use;
(ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads;
(iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system;
(iv) The device must be demonstrated to be biocompatible;
(v) Sterility testing must demonstrate the sterility of the device;
(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
(vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians;
(viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and
(ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.
