SPI® VARIO Angled Abutments are titanium dental implant abutments for use with the SP1® Dental Implant system. They connect with the internal hex feature of the implant, have a precision fit interface with the prosthetic attachment, and are intended for screw retained restorations in single unit and small multi-unit solutions. SPI VARIO Angled Abutments are designed for correction of implant divergence and can be used in combination restorations with SPI VARIO abutments.

Here's an analysis of the provided text regarding the acceptance criteria and study for the SPI® VARIO Angled Abutment.

It's important to note that the provided text is a 510(k) Summary, which focuses on demonstrating substantial equivalence to predicate devices, not on proving new clinical effectiveness or performance against specific acceptance criteria in the way an AI/ML device study might. Therefore, many of the typical questions for AI/ML device studies (like sample sizes for test/training sets, expert qualifications, adjudication, MRMC studies, standalone performance, etc.) are not applicable to this type of submission.

The "acceptance criteria" here are implicitly tied to demonstrating substantial equivalence through performance testing, primarily mechanical, rather than predictive accuracy.

Acceptance Criteria and Reported Device Performance

Study Details (Based on available 510(k) Summary Information)

1. Sample sizes used for the test set and the data provenance:

   • Test Set Sample Size: Not explicitly stated. The "performance testing" referenced is mechanical testing (ISO 14801), which would involve a certain number of physical units subjected to cyclic loading. This is physical device testing, not a clinical data test set.
   • Data Provenance: Not applicable in the sense of clinical data. This refers to laboratory-based mechanical testing of the device itself.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for mechanical testing is based on objective measurements against engineering standards (like ISO 14801), not expert interpretation.

3. Adjudication method for the test set: Not applicable. This is not a study involving human interpretation or subjective assessment that would require adjudication.

4. 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/ML device.

5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI/ML device.

6. The type of ground truth used: For the mechanical aspects, the ground truth is established by the specified ISO 14801 standard and the physical properties and failure points observed during testing. For biological aspects, it's the known biocompatibility and safety profile of the titanium material used, supported by the predicate devices.

7. The sample size for the training set: Not applicable. This is not an AI/ML device with a training set.

8. How the ground truth for the training set was established: Not applicable. This is not an AI/ML device with a training set.

Summary of the Study:

The "study" described in this 510(k) summary is not a clinical trial or an AI/ML performance study. Instead, it's a benchtop performance testing study focused on mechanical properties. The central purpose of the submission is to demonstrate substantial equivalence to already legally marketed predicate devices, not to establish novel clinical effectiveness or safety from a blank slate.

The key study mentioned is:

• Method: Performance testing "included methods described in ISO 14801." ISO 14801 is an international standard for dynamic loading of endosseous dental implants. This standard specifies methods for fatigue testing, which is crucial for dental implant components that experience cyclic forces during chewing.
• Purpose: To show that the SPI® VARIO Angled Abutment performs mechanically at a level comparable to the predicate devices and meets established industry standards for durability and strength.
• Conclusion: The results of this testing, combined with the similarity in materials, design principles, and intended use, were deemed sufficient by the FDA to demonstrate substantial equivalence to the predicate devices (K031747, K072856, K090153), leading to the clearance of the device.

Summary of Device and Approval Context:

• Device Name: SPI® Customizable Gingiva Former
• Intended Use: Used with SPI® System dental implants to provide temporary support for crowns or bridges in the maxillary and/or mandibular arch.
• Classification: Class II (Endosseous Dental Implant Abutment)
• Nature of Submission: Special 510(k) for a device modification. This implies the core technology and safety/effectiveness principles were established by previous predicate devices.
• Key Argument for Equivalence:
  • Same intended use
  • Same operating principle
  • Same or similar materials
  • Same basic design
  • Same packaging materials and processes

The FDA's letter explicitly states that they "have determined the device is substantially equivalent... to legally marketed predicate devices." This substantial equivalence determination is the primary "acceptance criterion" for a 510(k) submission, and it is "proven" by demonstrating that the modified device does not raise new questions of safety or effectiveness compared to the predicates, as outlined in the "Equivalence to Marketed Product" section.

No specific quantitative performance metrics (e.g., accuracy, sensitivity, specificity, or mechanical strength limits with associated test results) are detailed in the provided portion, which is common for Special 510(k)s focusing on material or design modifications where existing general controls and predicate device performance are considered sufficient. If mechanical testing (e.g., fatigue, fracture) was performed to support the modification, the specific acceptance criteria and results would typically be in a separate section of the 510(k) submission, often referencing ISO or ASTM standards, but they are not provided in this excerpt.

The system includes dedicated prosthetic components.

The provided text is a 510(k) summary for a dental implant abutment (SPI® VARIOmulti Angled Abutment). This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting entirely new clinical data or performance studies against specific acceptance criteria. Therefore, most of the requested information regarding acceptance criteria, specific device performance, sample sizes, expert involvement, and ground truth establishment will not be present in this document.

Here's a breakdown of what can be extracted and what cannot:

1. Table of Acceptance Criteria and Reported Device Performance:

• Acceptance Criteria: Not explicitly stated in terms of quantitative performance metrics for the device itself. The primary "acceptance criterion" for a 510(k) is demonstrating substantial equivalence to a predicate device.
• Reported Device Performance: No specific quantitative performance data is provided. The document states that the device is "substantially equivalent in indications and design principles to predicate devices."

2. Sample size used for the test set and the data provenance:

• Sample Size: Not applicable/not provided. This document doesn't describe a performance test set in the traditional sense with a specific sample size of units tested against acceptance criteria. The equivalence demonstration is likely based on design comparisons, materials testing, and adherence to relevant standards, not a clinical performance study with a "test set" of patients or devices.
• Data Provenance: Not applicable. No specific experimental data from a "test set" of patients or devices is referenced.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Number of Experts: Not applicable/not provided. Ground truth establishment is not relevant in this 510(k) summary as it does not rely on a clinical "test set" requiring expert evaluation.

4. Adjudication method for the test set:

• Adjudication Method: Not applicable/not provided. This is not a clinical study requiring adjudication of results.

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 Study: No. This device is a dental implant abutment, not an AI-assisted diagnostic tool.

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

• Standalone Study: No. This device is a physical medical device, not an algorithm.

7. The type of ground truth used:

• Type of Ground Truth: Not applicable. There is no specific "ground truth" referenced for performance testing in this document. Substantial equivalence in a 510(k) relies on comparison to a legally marketed predicate device's established safety and effectiveness.

8. The sample size for the training set:

• Sample Size for Training Set: Not applicable/not provided. This is not an AI/machine learning device, so there is no concept of a "training set."

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

• Ground Truth Establishment for Training Set: Not applicable.

Summary of the Study (Equivalence Demonstration):

The "study" described in this 510(k) summary is not a traditional clinical trial or performance study with acceptance criteria and specific performance metrics. Instead, it is a demonstration of substantial equivalence conducted as part of the FDA 510(k) premarket notification process.

• Methodology: Thommen Medical AG "demonstrated that... the SPI® VARIOmulti Angled Abutments are substantially equivalent in indications and design principles to predicate devices that have been determined by FDA to be substantially equivalent to preamendment devices." This involves comparing the new device's indications for use, technological characteristics (design, materials, intended function, attachment mechanism), and performance (often non-clinical testing like mechanical strength, fatigue, biocompatibility, but no specific data is included in this summary) to those of a legally marketed predicate device.
• Proof of Meeting Acceptance Criteria (Substantial Equivalence): The FDA's letter (K090153) explicitly states: "We have reviewed your Section 510(k) premarket notification... and have determined the device is substantially-equivalent... You may, therefore, market the device..." This letter serves as the FDA's "acceptance" that the device meets the regulatory requirements for market clearance based on substantial equivalence.

In essence, for a 510(k) submission, the "acceptance criteria" relate to regulatory compliance and the ability to demonstrate that the new device is as safe and effective as a legally marketed predicate device, rather than achieving specific quantitative performance thresholds from a de novo study.
