The provided FDA 510(k) clearance letter and its associated summary for the Neodent Implant System - Zirconia Implant System contain extensive information about the device, its intended use, and comparisons to predicate devices. However, it does not include specific acceptance criteria with numerical thresholds directly stated within the tables, nor does it detail a study that directly proves the device meets such criteria in terms of performance metrics like sensitivity, specificity, or image quality assessments.

Instead, the submission focuses on demonstrating substantial equivalence to predicate devices through various tests, implying that if the new device performs similarly to or better than previously cleared devices, it meets the necessary standards. The performance testing section describes the types of tests conducted (e.g., dynamic fatigue, torsion, insertion, pull-out, and software validation), but it does not present clear quantitative acceptance criteria or the specific performance results in a comparative table format.

Therefore, many of the requested fields cannot be directly extracted from the provided text as they pertain more to the performance evaluation of AI/software in interpreting medical images, which is not the primary focus of this dental implant submission.

Here's an attempt to answer the questions based on the available information, noting where information is not explicitly provided in the document:

Acceptance Criteria and Device Performance Study for Neodent Implant System - Zirconia Implant System

The FDA 510(k) summary for the Neodent Implant System - Zirconia Implant System focuses on demonstrating substantial equivalence to predicate devices through a combination of bench testing, software validation, MRI compatibility, biocompatibility, and sterilization validation. It does not present specific quantitative acceptance criteria or performance metrics directly from a comparative study in the way one might expect for an AI/software-based medical device (e.g., sensitivity, specificity thresholds). Instead, the "acceptance criteria" are implicitly met by demonstrating that the proposed devices perform at a level substantially equivalent to legally marketed predicate devices under standardized testing conditions.

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

As mentioned, explicit numerical acceptance criteria and reported device performance in a comparative table (e.g., for diagnostic accuracy) are not provided in this 510(k) summary. The summary indicates that tests were conducted according to relevant ISO standards and FDA guidance, and the results demonstrated that the subject devices exhibit a level of performance substantial equivalent to the predicate and reference devices.

Below is a conceptual table based on the types of tests mentioned, noting that specific numerical acceptance criteria and performance data are not detailed in the provided text.

They must be sent to a Straumann Validated Milling

This document describes the Neodent Implant System - Custom Abutments and its FDA 510(k) clearance (K250614). The information provided is primarily focused on demonstrating substantial equivalence to a predicate device, rather than detailed performance study results with specific acceptance criteria and performance metrics for a novel AI/software device.

Based on the provided text, the device is a physical medical device (dental implant abutment) and not an AI/software device. Therefore, the questions related to AI/software performance studies, such as sample size for test sets, expert adjudication, MRMC studies, standalone algorithm performance, and training set details, are not applicable to this submission.

The "Performance Testing" section primarily describes bench testing (dynamic fatigue and torsion tests), biocompatibility testing, and sterilization validation, which are standard for physical medical devices.

Here's a breakdown of the available information:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" in the format typically seen for performance metrics of a diagnostic device. Instead, it describes general compliance with standards and the determination of "not a new worst case" for dynamic fatigue.

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

• Sample Size for Bench Testing (Dynamic Fatigue and Torsion): Not
  explicitly stated. The document mentions "a worst case analysis determined that the subject devices are not a new worst case compared to those devices tested for the primary predicate." This implies that testing was performed on a sufficient number of samples to make this determination, likely following the requirements of ISO 14801.
• Data Provenance: Not explicitly stated, but these are typically laboratory-based bench tests performed by the manufacturer or a contracted testing facility.

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

• Not Applicable. This is a physical device, and the testing involves objective measurements (e.g., force, torque, material properties) rather than expert interpretation of data for ground truth establishment.

4. Adjudication Method for the Test Set

• Not Applicable. As above, the tests are objective physical measurements.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done

• Not Applicable. This is a physical device, not an AI-assisted diagnostic or decision support system.

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

• Not Applicable. This is a physical device. While it involves digital design using CAD/CAM software, the 'device' itself is the physical abutment, and its performance is evaluated through physical and material tests, not software algorithm performance.

7. The Type of Ground Truth Used

• Physical/Material Standards and Engineering Specifications. For dynamic fatigue and torsion tests, the "ground truth" or acceptance criteria are derived from established engineering principles, material properties (ASTM F136 for titanium alloy), and international standards (ISO 14801). For biocompatibility, it's compliance with ISO 10993 series.

8. The Sample Size for the Training Set

• Not Applicable. This is a physical device; there is no "training set" in the context of machine learning or AI models.

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

• Not Applicable. As above, no training set for an AI/ML model for this physical device.

The NeoConvert Solution may be used with single-stage or two-stage procedures, for temporary multiple unit restorations, and may be loaded immediately when good primary stability is achieved and with appropriate occlusal loading.

Direct Screw to MUA: The Neodent Implant System is intended to be surgically placed in the bone of the upper or lower jaw to provide support for prosthetic devices, such as artificial teeth, to restore chewing function. The Direct Screw to MUA may be used with single-stage or two-stage procedures, for screw-retained multi-unit restorations, and may be loaded immediately when good primary stability is achieved and with appropriate occlusal loading. All digitally designed personalized copings to be used with the Direct to Multi Unit Abutment Screw are intended to be sent to Straumann for manufacture at a validated milling center.

GM Attachment TiN 30°: The Neodent Implant System is intended to be surgically placed in the bone of the upper or lower jaw to provide support for prosthetic devices, such as artificial teeth, to restore chewing function. The GM Attachment TiN 30° may be used with single-stage or two-stage procedures, for multiple unit restorations, and may be loaded immediately when good primary stability is achieved and with appropriate occlusal loading.

This premarket notification includes the following additions to the Neodent Implant System: NeoConvert Solution, Direct Screw to MUA, GM Attachment TiN 30°. The Neodent Multi-Unit Abutments proposed on this submission are similar to devices already cleared in previous submissions of Neodent Implant System, according to predicate devices described above. This submission intends to expand the portfolio of Neodent Abutments with these new solutions for multi-unit restorations, to provide more treatment options to customers. The NeoConvert Solution is a technique comprised by some abutments (not subject of this submission) used for converting removable temporary prosthesis into a screw-retained fixed temporary prosthesis. The Direct Screw to MUA is a prosthetic component designed to fix planned and digitally designed multi-unit milled restorations directly onto mini or micro abutments, eliminating the need for using the passive seating cylinder to restore chewing function. The GM Attachment TiN 30° is a prosthetic component used to stabilize implant-mucosa-supported removable full prosthesis (retained on the implant and supported on the mucosa), on implants installed in the maxilla or mandible. Although all these three new solutions are compatible with the same implants and components of Neodent Implant System and used for multiple unit rehabilitation, they are not used in conjunction with each other.

The provided text describes a 510(k) premarket notification for the "Neodent Implant System," focusing on the NeoConvert Solution, Direct Screw to MUA, and GM Attachment TiN 30°. This document details the device's technical characteristics, intended use, and its substantial equivalence to previously cleared predicate devices.

However, the provided text does not contain information about acceptance criteria and a study proving a device meets those criteria in the context of an AI/ML medical device submission. The document is a traditional 510(k) submission for dental implants and abutments, which are physical medical devices, not AI/ML software. Therefore, the specific requirements for an AI/ML device study (such as sample sizes for test and training sets, expert qualifications for ground truth, MRMC studies, or standalone performance) are not applicable or present in this document.

The "Performance Testing" section (pages 15-16) describes bench testing (dynamic fatigue, torsion, SEM images), MRI compatibility testing, biocompatibility testing, sterilization validation, and shelf-life testing for the physical dental implant components. These are standard performance tests for this type of physical device, not AI/ML algorithm validation.

Therefore, I cannot provide a table of acceptance criteria and a study proving the device meets acceptance criteria as typically outlined for an AI/ML medical device, as this information is not present in the provided document. The document focuses on demonstrating substantial equivalence of a physical dental device to predicate devices through engineering and material testing.

These abutments are composed of a unique body with two regions: the upper region is the customized portion, while the end region presents the prosthetic interface that fits with the implant, which does not allow customization.

They are intended for single use and provided non-sterilization recommended before installation in the mouth.

All proposed abutments are delivered to the final user already customized in a validated milling center, with a straight channel solution. For the GM line, the abutments could also be milled with a new angled channel solution for the screw access. All subject devices must be used with their corresponding prosthetic interface.

The provided text describes the Neodent Implant System - Custom Abutments, a medical device. This product is not an AI/ML device, and therefore does not have acceptance criteria or a study that proves the device meets those criteria in the way requested in the prompt.

The document discusses the substantial equivalence of the Neodent Implant System - Custom Abutments to legally marketed predicate devices, which is the basis for its 510(k) clearance by the FDA. The performance testing section describes bench tests (dynamic fatigue and torsion tests), sterilization validation, MR compatibility testing, and biocompatibility testing. These tests evaluate the physical, chemical, and biological properties of the device, comparing them to established standards and predicate devices to demonstrate equivalence, not to meet a set of acceptance criteria for an AI/ML algorithm's performance.

Because the device is not an AI/ML device, the specific information requested about acceptance criteria for AI performance, sample sizes for test/training sets, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone performance, and how ground truth for training was established is not applicable and is not present in the provided text.

They are intended for single use and provided sterile via Ethylene Oxide method. The new transmucosal heights are 3.5mm and 4.5mm.

The restorative materials Polycon ae, N!ce and IPS e.max CAD LT were not presented in previous submissions of Zirconia Implant System and are being included in the scope of Zirconia Bases indication.

The provided document is a 510(k) summary for the Neodent Implant System - Zirconia Implant System. This type of FDA submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving a device meets specific acceptance criteria through a clinical study with defined performance metrics, sample sizes, and expert adjudication as might be seen for novel AI/software as a medical device (SaMD) products.

Therefore, the document does not contain the information requested regarding acceptance criteria related to a study proving performance, sample sizes for test sets, data provenance, number or qualifications of experts for ground truth, adjudication methods, MRMC studies, standalone algorithm performance, or ground truth establishment methods for training sets.

The performance testing section (pages 14-15) describes:

• Bench Testing:
  • Dynamic fatigue testing: Conducted according to FDA guidance and ISO 14801. The results demonstrated the subject devices do not introduce a new worst case compared to predicate and reference devices.
  • Torsion tests: Performed to evaluate screw strength, and results proved adequate torsion strength according to installation torque.
• Biocompatibility Testing:
  • Assessment performed according to ISO 10993-1 and FDA guidance. No new issues were raised and no additional testing was required because the subject devices are identical in material and manufacturing processes to predicate and reference devices.
• Sterilization Validation and Packaging:
  • Ethylene Oxide (EO) sterilization validated to SAL of 10-6 per ISO 11135:2014. EO residuals verified per ISO 10993-7. The packaging and sterilization are identical to predicate devices.
  • Steam sterilization validated per ISO 17665-1, using parameters identical to predicate devices.
  • Pyrogen limit specifications met via LAL Endotoxin Analysis (testing limit 20 EU/device) for blood contacting and implanted devices.

Here's an analysis of the acceptance criteria and supporting studies for the Neodent Implant System - Helix Short Implant System, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The FDA 510(k) summary does not explicitly present a table of specific numerical acceptance criteria alongside reported performance for each test. Instead, it describes what was tested and states that the results "met the acceptance criteria" or demonstrated "equivalent performance." We can infer the general acceptance criterion from the study descriptions.

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

The document does not explicitly state the numerical sample size for the test sets in the mechanical, MR compatibility, or other in-vitro studies. It refers to "tested subject devices" or "representative samples."

• Data Provenance: The studies described (mechanical testing, MR compatibility, surface treatment, sterilization, endotoxin, shelf life, biocompatibility) are all benchtop/laboratory studies (in vitro). There is no mention of human subject data, animal data, or clinical retrospective/prospective data for these specific performance criteria. The manufacturer is JJGC Indústria e Comércio de Materiais Dentários S.A. (dba Neodent) based in Curitiba, Paraná, Brazil.

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

Not applicable. As these are benchtop/laboratory performance studies, "ground truth" is established by adherence to recognized standards (e.g., ISO 14801, ISO 11137, ISO 11135, ISO 10993) and scientific methods, not by expert consensus in the typical sense for clinical data.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods like 2+1 or 3+1 are typically used for interpreting clinical images or patient outcomes, not for objective benchtop performance data against engineering standards.

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 an endosseous dental implant system, which is a physical medical device, not an AI-powered diagnostic or assistive tool. Therefore, MRMC studies involving human readers and AI assistance are not relevant.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not applicable, as this is a physical medical device, not an algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the performance claims is based on:

• Adherence to International Standards: Performance measured against specifications outlined in standards like ISO 14801 (dynamic fatigue), ISO 11137 and ISO 11135 (sterilization), ISO 10993 series (biocompatibility).
• Benchtop Test Results: Direct measurements and observations from the mechanical, physical, chemical, and biological laboratory tests performed on the device.
• Comparison to Predicate Devices: Performance is frequently established by demonstrating equivalence or superiority to already legally marketed predicate devices, which serve as a benchmark.

8. The Sample Size for the Training Set

Not applicable. This is a physical medical device. The concepts of "training set" and "validation set" are primarily used for machine learning and AI, not for the regulatory approval of physical implants based on benchtop testing.

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

Not applicable for the same reasons as point 8.
