The implant system is intended to be surgically placed in the maxilla or mandible to provide support for prosthetic devices such as artificial teeth in order to restore chewing function. It may be used with single-stage or two-stage procedures, for single or multiple unit restorations, and may be loaded immediately when good primary stability is achieved and with appropriate occlusal loading. Multiple tooth applications may be rigidly splinted.

Anthogyr Multi-Unit prosthetic components directly or indirectly connected to the endosseous dental implants are indicated for use to provide support for multiple-unit prosthetic reconstructions such as bridges and bars. The final devices have the purpose of restoring chewing function. Temporary components can be used prior to the final components to maintain, stabilize and shape the soft tissue during the healing phase. The temporary restoration may not be placed into occlusion.

Temporary components have a maximum duration of usage of 180 days.

The OPMUN0-0 abutments are indicated for maxillary lateral and mandibular central/lateral incisors only.

The provided text describes a 510(k) summary for Anthogyr AXIOM® BL X3 implants and Anthogyr Multi-Unit components for AXIOM® BL. This document evaluates the substantial equivalence of new devices to existing legally marketed predicate devices, rather than establishing acceptance criteria and providing direct evidence of device performance against those criteria in a typical clinical study format.

Therefore, the requested information elements related to "acceptance criteria and reported device performance tabletop," "sample size for test set," "data provenance," "number of experts and qualifications," "adjudication method," "multi-reader multi-case (MRMC) comparative effectiveness study," "standalone performance," "type of ground truth," "sample size for training set," and "how ground truth for training set was established" are not applicable in the context of this 510(k) submission summary.

This document focuses on demonstrating that the new devices are substantially equivalent to predicate devices through comparisons of technological characteristics and performance testing (e.g., dynamic fatigue, biocompatibility, sterilization validation). The "acceptance criteria" here implicitly refer to demonstrating equivalence to the predicate devices and compliance with relevant standards and FDA guidance.

Here's an overview of the performance testing performed, interpreted as demonstrating compliance/equivalence rather than explicitly stated acceptance criteria with numerical performance targets:

1. Acceptance Criteria and Reported Device Performance:

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

• This information is not provided in the 510(k) summary. The summary refers to "tests were conducted" and "results were substantially equivalent," but actual sample sizes for mechanical, sterilization, or other tests are not detailed. The data provenance (e.g., country of origin, retrospective/prospective) is also not mentioned.

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

• Not applicable. This is a medical device, not an AI/software device requiring ground truth established by experts for a test set. The "ground truth" for non-AI devices is typically established through direct physical measurements, chemical analyses, and standardized test methodologies.

4. Adjudication Method 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 not an AI/imaging device.

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

• Not applicable. This is not an AI/software device.

7. The Type of Ground Truth Used:

• For a traditional medical device like a dental implant, "ground truth" refers to established physical, chemical, and biological properties measured through standardized testing. Examples include:
  • Mechanical properties: Measured against international standards (e.g., ISO, ASTM) or FDA guidance for dental implants/abutments (e.g., fatigue strength, fracture resistance).
  • Biocompatibility: In vitro (e.g., cytotoxicity tests under ISO 10993-5) and in vivo tests (if new materials are introduced) against established biological safety profiles.
  • Sterilization efficacy: Measured by demonstrating a Sterility Assurance Level (SAL) of 10⁻⁶ via methods compliant with ISO 11137-1 (radiation) or ISO 17665-1 (moist heat).
  • Material composition: Chemical analysis to confirm compliance with medical-grade specifications (e.g., Titanium-6Al-4V ELI conforming to ASTM F136).

8. The Sample Size for the Training Set:

• Not applicable. This is not an AI/software device that uses a "training set."

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