All abutments are only intended to be digitally designed and manufactured using specifics CAD/CAM software according to digital dentistry workflow. Custom Abutments with Angled Screw Channel are indicated for screw-retained single restorations or cemented retained single or multiple restorations. All digitally designed abutments for use with the Custom Abutment Ti with Angled Screw Channel are intended to be sent to Straumann for manufacturing at a validated milling center.

ASC Screw:
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. 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.

This premarket notification includes new digital abutments to the Neodent Implant System (GM, NGM and HS prosthetic interfaces). The abutments proposed on this submission are identical to devices already cleared in previous submissions of Neodent Implant System, according to predicate devices described above, being the only difference between them the introduction of a new angled channel solution. This submission intends to expand the portfolio of Neodent Implant System. The Custom Abutments AS Ti are composed of a unique body with two different regions: the upper region, which is the customizable portion, and the end region presents the prosthetic interface that fits with the implant, which does not allow customization. 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.

NeoConvert Solution: 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 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.
