Each description details the intended use, material, surface treatment, sterilization, single use status, dimensions, and compatible implant systems.

The provided document, a 510(k) premarket notification from MegaGen Implant Co., Ltd. for their "MegaGen Dental Implant Abutment" device, focuses on demonstrating substantial equivalence to previously cleared predicate devices rather than proving that the device meets specific acceptance criteria through a standalone study.

For medical devices, especially those going through the 510(k) pathway, acceptance criteria are typically based on showing that the new device performs as safely and effectively as a legally marketed predicate device. The "study" proving this is primarily a non-clinical performance testing (bench testing) and a comparison to predicate devices. Clinical studies are often not required for 510(k) submissions, as explicitly stated in this document ("No clinical studies are submitted.").

Therefore, the acceptance criteria are implicitly defined by the performance characteristics of the predicate devices and general standards (like ISO 14801 for dental implants) as outlined in the "Summary of Non-Clinical Testing" section. The device performance is demonstrated through a comparative analysis to these predicates and the results of the bench testing.

Here's a breakdown of the information requested, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Given that this is a 510(k) submission, the "acceptance criteria" for the subject device are fundamentally its demonstration of substantial equivalence to predicate devices, meaning it performs as safely and effectively. The "reported device performance" is a direct comparison to the predicate devices and adherence to relevant standards.

The document provides extensive comparison tables for each component of the MegaGen Dental Implant Abutment system against its predicate and reference devices. Below is a representative excerpt from these tables, focusing on a few key components to illustrate the comparison:

Example: Scan Healing Abutment

Summary of Device Performance (Based on "Substantial Equivalence Discussion" sections for all components):

The subject device is deemed substantially equivalent to its predicate/reference devices across all listed components (Scan Healing Abutment, Temporary Abutment, Temporary Cylinder, Comfort Cap, Healing Cap, Healing Cap Screw, Milling Abutment, EZ Post Abutment/Extra EZ Post Abutment, EZ Post Cylinder, ZrGEN Abutment, Multi-unit Abutment, Multi-unit Angled Abutment, AXA Abutment (Straight), AXA Abutment (Angled), Abutment Screw, Cylinder Screw, Crown Screw).

Any identified differences in characteristics (e.g., specific dimensions like diameter, gingival height, post height, total length, or surface treatment for some components) are explicitly discussed and concluded not to affect substantial equivalence. This is often supported by arguing that the differences are minor, fall within the range of cleared devices, allow for more precise treatment, or are supported by bench testing (e.g., fatigue tests for worst-case scenarios).

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

The document does not detail specific sample sizes for test sets in the context of clinical data, as no clinical studies were submitted.

For non-clinical testing (bench tests), the document states:

• "The bench tests have been performed in accordance with 'ISO 14801' and the recommendations of 'Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutment' to evaluate the performance of the subject devices and the test results met the pre-set criteria."
• For ZrGEN Abutment, AXA Abutment (Angled type), and other potentially "worst-case" scenarios, fatigue tests were conducted to demonstrate performance and stability.

The data provenance is pre-market non-clinical testing data generated by the manufacturer. The country of origin for the manufacturing and testing is Republic of Korea (MegaGen Implant Co., Ltd. is based in Daegu, Republic of Korea). The data is prospective in the sense that it was specifically generated for this 510(k) submission to demonstrate equivalence.

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

This information is not applicable (N/A) as no clinical studies were conducted or submitted. For non-clinical bench testing, "ground truth" is established by adherence to recognized standards (like ISO 14801) and established testing methodologies, not typically by expert consensus of medical professionals on a test set.

4. Adjudication Method for the Test Set

This information is N/A as no clinical studies with human readers or image interpretation were conducted.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size of Human Readers Improvement

This information is N/A as no clinical studies were conducted, and certainly no MRMC studies involving human readers, as this is a physical dental implant component, not an AI or imaging device that would typically involve human-in-the-loop performance evaluation.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

This information is N/A as the device is a physical dental implant abutment, not a software algorithm.

7. The Type of Ground Truth Used

For the purpose of this 510(k) submission, the "ground truth" for demonstrating substantial equivalence is:

• Performance specifications derived from legally marketed predicate devices.
• Adherence to recognized international standards (e.g., ISO 14801 for mechanical properties, ISO 10993-1 for biocompatibility, ISO 11137 for sterilization) for manufacturing and material properties.
• Results of non-clinical bench testing to confirm physical and mechanical performance characteristics.

There is no "expert consensus," "pathology," or "outcomes data" in the typical sense of a clinical study since none were performed.

8. The Sample Size for the Training Set

This information is N/A. The device is a physical product, not an AI/ML model that requires a "training set."

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

This information is N/A as there is no training set for a physical device.

This system is dedicated for one and two stage surgical procedures. This system is intended for delayed loading.

Dentis s-Clean Regular Abutment is intended for use as an aid in prosthetic restoration. It consists of Abutments, components, and Abutment screws.

Here's an analysis of the provided text regarding acceptance criteria and supporting studies. It's important to note that this document is a 510(k) summary for a dental implant abutment, and as such, it focuses on demonstrating "substantial equivalence" to existing cleared devices rather than establishing novel safety and effectiveness criteria from scratch. Therefore, the "acceptance criteria" here are largely implied by the equivalence to predicate devices and adherence to relevant standards.

General Observation: The document primarily focuses on demonstrating substantial equivalence (SE) based on comparing the subject device's (Dentis s-Clean Regular Abutment) technical characteristics, materials, and intended use to various predicate and reference devices. The "performance" being evaluated is largely through compliance with international standards and leveraging prior testing on similar devices. There isn't a direct "device performance" in terms of clinical outcomes with AI assistance or human reader improvement, as this is a physical medical device (dental abutment).

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

Given the nature of the device (dental abutment) and the submission type (510(k) for substantial equivalence), the "acceptance criteria" are predominantly about meeting material specifications, standardized mechanical testing, and demonstrating equivalence in design and intended use to legally marketed predicate devices. The "reported device performance" is largely the successful completion of these tests or the justification for leveraging prior testing.
