The LOCATOR Angled Abutment is indicated for the attachment of full or partial, fixed and removable restorations retained by endosseous implants to restore masticatory function for the patient.

The purpose of this submission is to expand the Indications for Use of the LOCATOR® Angled Abutment product line (K243272 & K233587) by adding compatibility of existing abutments with various new dental implant systems from Implant Direct and Biohorizons. Additionally, the submission expands the Indications for Use of the product line with a modified version of the predicate device shown to be compatible with the Implant Logistics Implant-One Series 300 and Series 400 Implant Systems. The LOCATOR Angled Abutment is designed and intended for the attachment of full or partial, fixed and removable, restorations retained by endosseous implants in the mandible or maxilla, as cleared to be used with LOCATOR FIXED (K213391) and LOCATOR Attachment Systems (K072878).

The LOCATOR Angled Abutments are manufactured from titanium (Ti-6Al-4V) and are titanium nitride (TiN) coated in various abutment heights, identical to the predicate device. The LOCATOR Angled Abutment interfacing features are provided at a 15 degree angle to allow for angle correction, substantially equivalent to the predicate device of K233587 and K243272. The abutments will be used with the accessories of the LOCATOR Implant Attachment System (retention inserts, denture attachment housing, and ancillary processing parts) and LOCATOR FIXED Attachment System (fixed inserts, denture attachment housing) for the attachment of a restoration, identical to the predicate device.

The provided document is an FDA 510(k) clearance letter for the LOCATOR® Angled Abutment, K250721. This document primarily focuses on demonstrating substantial equivalence to a predicate device and expanding indications for use, rather than detailing a study that proves the device meets specific performance acceptance criteria for a new clinical application.

Therefore, much of the requested information regarding study design, sample sizes, expert involvement, and ground truth establishment (which are typical for AI/ML device clearances or those requiring extensive clinical performance data) is not present in this type of regulatory submission for a dental implant abutment.

However, based on the information provided, I can construct a table for the acceptance criteria and reported "performance" in the context of this 510(k) submission, which is primarily a demonstration of mechanical compatibility and safety rather than a clinical efficacy study.

Here's an interpretation based on the provided text:

Overview of Device Performance and Acceptance Criteria (as per the 510(k) Submission)

The LOCATOR® Angled Abutment (K250721) is a dental implant abutment. The "study" proving it meets acceptance criteria in this context is a series of non-clinical tests and engineering analyses demonstrating its compatibility with various dental implant systems and confirming its mechanical properties and biocompatibility are substantially equivalent to previously cleared devices. The acceptance criteria are implicitly met by showing conformance to established standards and similarity to predicate devices.

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size: Not explicitly stated as "sample size" in the conventional sense for a clinical trial. For physical testing (fatigue, packaging), standard engineering test specimen numbers would have been used, but these are not detailed. For material and biocompatibility, existing data was leveraged. Functional compatibility was primarily through engineering analysis.
• Data Provenance: The data comes from in-vitro non-clinical testing and engineering analyses conducted by the manufacturer, Zest Anchors, LLC, or leveraged from previous submissions (K243272, K233587, K213391, K072878, K173701, K102822). The origin is the manufacturer's internal testing and regulatory submissions. The nature of these tests is "retrospective" in the sense that results from previous validated tests (e.g., K233587 for TiN coating, K072878 for biocompatibility) are being applied ("leveraged") to demonstrate equivalence for the current device, implying these tests were performed in the past.

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

• Number of Experts: Not applicable. For this type of device (dental abutment) and submission (510(k) for expanded compatibility), "ground truth" is established through engineering specifications, material standards, and validated physical/mechanical testing protocols (e.g., ISO, ASTM). It does not involve human expert consensus on clinical images or patient outcomes.
• Qualifications of Experts: N/A, as the "ground truth" is based on objective, standardized physical and material properties, confirmed by engineering analysis.

4. Adjudication Method for the Test Set

• Adjudication Method: Not applicable. This is not a study requiring human adjudication of results. Engineering and laboratory tests have objective pass/fail criteria or conformance to standards.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• MRMC Study Done? No. MRMC studies are typically for AI/ML devices where human readers interpret diagnostic images. This device is a physical dental implant component.
• Effect Size of Human Readers Improvement: Not applicable.

6. Standalone Performance Study (Algorithm Only)

• Standalone Performance Study Done? No. This device is a physical medical device, not an algorithm.

7. The Type of Ground Truth Used

• Type of Ground Truth: The "ground truth" for this device's "performance" and "acceptance" is based on:
  • Engineering specifications and drawings: Ensuring physical compatibility (e.g., fit with implants).
  • International Standards: Conformance to mechanical testing standards (ISO 14801:2016 for fatigue), material standards (ASTM F136), and biocompatibility standards (ISO 10993 series).
  • Predicate device performance: Demonstrating that the subject device's design, materials, and performance characteristics are "identical" or "substantially equivalent" to previously cleared devices.

8. The Sample Size for the Training Set

• Sample Size for Training Set: Not applicable. This is not an AI/ML device that requires a training set.

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

• How Ground Truth Established: Not applicable.

The provided document is a 510(k) Summary for a dental device (Inclusive® Titanium Abutments). It details the device's technical characteristics and claims substantial equivalence to a predicate device based on non-clinical testing. However, it does not include specific quantitative acceptance criteria or detailed results of a study designed to compare the device performance against such criteria.

The document discusses "performance data" in general terms, referring to several non-clinical tests (Biocompatibility, Mechanical Properties, Sterilization Validation, Shelf Life and Packaging Validation, and Use in MR Environment). It states that these tests were performed to "demonstrate substantial equivalence" and to "address questions related to substantial equivalence based on the differences in technical specifications," but it doesn't present the data in a way that allows for filling out the requested table of acceptance criteria and reported performance.

Therefore, I cannot provide a table of acceptance criteria and reported device performance, nor can I answer questions 2 through 9 regarding sample size, data provenance, expert involvement, adjudication, MRMC studies, or training set details, as this information is not present in the provided text.

The document explicitly states:

• "Non-clinical testing data are submitted to demonstrate substantial equivalence. No clinical data was included in this submission."

This indicates that clinical trials with human subjects, which would typically involve expert ground truth establishment and detailed performance metrics comparing against specific acceptance criteria, were not part of this submission for substantial equivalence.

The "Mechanical Properties" section mentions:

• "Static load and fatigue testing of the implant/abutment assembly was considered according to the FDA Guidance Document, Guidance for Industry and FDA Staff Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments and ISO 14801:2016 standard with the worst-case scenario. The fatigue limit data demonstrated that the subject device has sufficient strength for its intended use."

This implies that there were performance targets based on ISO 14801:2016 for fatigue strength, but the specific acceptance critiera (e.g., minimum fatigue strength in Newtons) and the actual reported performance values are not provided in this summary. It only states that the device "has sufficient strength."

All abutments are provided with the appropriate abutment screw (ff applicable) for attachment to the corresponding implant. All abutments and screws are provided non-sterile. The subject device is only intended for multi-unit restorations such as bridges and bars.

This appears to be a 510(k) Summary for a medical device (dental abutments) rather than a study report with acceptance criteria for an AI/ML powered device. The document describes the device, its intended use, comparison to predicate devices, and non-clinical performance data (mechanical testing, biocompatibility, sterilization validation, MRI compatibility). It explicitly states: "No clinical data were included in this submission."

Therefore, I cannot extract acceptance criteria or information about a study that proves the device meets those criteria in the context of an AI/ML device, as the provided text doesn't describe such a device or study.

If the request was based on a misunderstanding of the document's content, please clarify. If you're looking for general information on what would be included in such a study for an AI/ML device, I can provide a theoretical outline.

The provided text is a compilation of Indications for Use statements for various dental implant systems and components, all under the umbrella of "Implant Direct Dental Implant Systems Portfolio - MR Conditional." Each section describes the intended use for a specific product or family of products, often referencing previous 510(k) clearances.

Crucially, this document does not contain any information about acceptance criteria or studies that prove the device meets these criteria. It is a regulatory filing for the Indications for Use for a medical device which has already been cleared by the FDA to be "substantially equivalent" to predicate devices.

Therefore, I cannot fulfill the request to describe acceptance criteria and the study that proves the device meets the acceptance criteria based solely on the provided text. The document is for describing what the device is for, not how its performance was tested or validated.

  Custom InterActive Titanium Abutments are compatible at the implant-level with InterActive, SimplyInterActive and SwishActive implants, excluding 6mm length implants.

The Custom Legacy Titanium Abutments and Custom InterActive Titanium Abutments (collectively the "Custom Titanium Abutments") are one-piece hex type engaging abutments comprised of Titanium 6AL-4V ELI, which serve as a final abutment upon which a prosthetic dental restoration will be fitted.
The Custom Legacy Abutments are offered in 3.0mm, 3.5mm, and 5.7mm diameters that correspond to the platform diameters of the Legacy Implant System; the Custom InterActive Abutments are offered in 3.0mm and 3.4mm diameters that correspond to the InterActive Implant System. The devices are supplied with fixation screws that are placed through the abutment to secure it to the implant's reciprocal hex platform. The Custom Abutments are provided with a large amount of modifiable material to accommodate the digital workflow used for device customization. Customization of the final abutment is performed in Implant Direct's Custom Direct laboratory under Implant Direct's manufacturing control, where the devices are milled to meet individual patient specifications. The digital workflow uses the following additional devices:

• 3Shape Abutment Design Software (K151455)
• Dental System Control Panel
• Dental Designer
• Lab Scanner (3Shape D700 and 3Shape Scan-it Restoration Dental System (510(k)-exempt, Product Code NOF)

Implant Direct will design an abutment and forward the design to the end user for approval prior to manufacturing. With the Mill-only process flow, the end user uses intra-oral scanners and lab scanners to design the abutment using the 3Shape software. The abutment design file (.stl) is sent to Implant Direct for manufacturing.
  The Custom Abutments are single-use and supplied non-sterilization by the end user. They are externally-communicating devices which come in permanent contact (>30 days) with a patient's tissue/bone.

This document is related to a 510(k) premarket notification for dental implant abutments, which are physical medical devices, not AI/software-based devices. Therefore, the concepts of "acceptance criteria for an AI model," "study proving the device meets acceptance criteria" (in the context of algorithm performance), "test set," "training set," "ground truth establishment," "experts," "adjudication," and "MRMC studies" are not applicable here.

The document discusses performance data for the physical dental abutments, but this refers to traditional engineering and biological testing, not AI model validation.

Here's a breakdown of why your desired information isn't present in this document:

• Device Type: The device is "Custom Legacy and Custom InterActive Titanium Abutments," which are physical, custom-milled dental prosthetics. They are not AI algorithms.
• Study Purpose: The studies mentioned (Biocompatibility, Fatigue Testing, Steam Sterilization, Software Verification and Validation) are engineering and biological tests designed to ensure the physical device is safe and performs its mechanical function, and that the design software adheres to specified parameters. They are not studies to evaluate the diagnostic or predictive performance of an AI model.

However, I can extract information related to the device's technical specifications and how its engineering performance was validated:

Acceptance Criteria and Device Performance (in a physical device context):

The document details various non-clinical tests performed to support the device's safety and performance, acting as "acceptance criteria" for a physical medical device. The "reported device performance" is that the device passed these tests, indicating it performs as intended and is substantially equivalent to predicate devices.

Table of "Acceptance Criteria" and "Reported Device Performance" (adapted for a physical device K192218):

Regarding the other points, as they pertain to AI/ML, they are not applicable to this physical device submission:

1. Sample size for the test set and data provenance: Not applicable. This document refers to the number of physical abutment samples tested for biocompatibility and fatigue, not a test set for an AI model.
2. Number of experts and qualifications for ground truth: Not applicable. Ground truth for an AI model's performance on medical images is irrelevant for this physical device.
3. Adjudication method: Not applicable.
4. Multi-Reader Multi-Case (MRMC) comparative effectiveness study: Not applicable. This is for evaluating changes in human reader performance with AI assistance, which is not relevant here.
5. Standalone (algorithm only) performance: Not applicable. The device itself is a physical object; there's no "algorithm-only" performance to evaluate in this context. The software mentioned (3Shape Abutment Designer) is a design tool, not a diagnostic or predictive AI.
6. Type of ground truth used: Not applicable. Ground truth for AI (e.g., pathology, outcomes) is not relevant for testing the mechanical and biological properties of a dental abutment.
7. Sample size for the training set: Not applicable. There is no AI training set for this physical device.
8. How the ground truth for the training set was established: Not applicable.

In summary, this document thoroughly covers the engineering and biological validation required for a Class II physical medical device, demonstrating its substantial equivalence to predicate devices through well-defined tests, but it does not contain information about AI model validation.

InterActive/SwishActive Implant System consists of two-piece implants for one-stage or two-stage surgical procedures. These implants are intended for use in partially and fully edentulous upper and lower jaws in support of single or multiple-unit restorations and terminal or intermediate SMARTBase support for fixed bridgework. The system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories. The SMARTBase Abutments consist of two major parts. Specifically, the titanium base and zirconia top components make up a two-piece abutment.

Implants can be indicated for immediate loading when good primary stability has been achieved and with appropriate occlusal loading.

• Narrow Diameter (3.2. 3.3mm) Implants: Indicated for single-tooth replacement of mandibular central and lateral incisors and maxillary lateral incisors. Also indicated for multiple tooth replacements or denture stabilization.

The InterActive SMARTBase abutments system is a line extension of the previously cleared Implant Direct device, 2014 InterActive/SwishActive Implant System. The InterActive SMARTBase abutments are comprised of engaging abutments, non-engaging abutments, modified zirconia engaging abutments, modified zirconia non-engaging multiunit bridges, and fixation screws that are intended to function as an extension of the implant. The proposed SMARTBase Abutment is a two-piece abutment consisting of titanium base and zirconia top components. To fabricate the zirconia top component that fits the titanium base, there are three workflow options: (1) using a press-ceramic material that is formed by conventional wax-up technique by the end user, (2) the zirconia top component is designed and milled by Implant Direct in stock sizes and provided to the end user to be placed on the titanium base for forming two-piece abutment, and (3) digital workflow using 3Shape where CAD design and milling of the zirconia top component is done at the end user's dental laboratory/office to be placed on the titanium base. The CAD design requires loading of Implant Direct abutment design library to the 3Shape Software to design the zirconia top component within the established design limitations and specifications.

The provided document describes the FDA's 510(k) clearance for the InterActive SMARTBase Abutments, which is a dental implant component. The document focuses on demonstrating substantial equivalence to a predicate device rather than providing a detailed study proving the device meets specific acceptance criteria in the manner one might find for a novel AI device.

Therefore, much of the requested information regarding detailed acceptance criteria, sample sizes for test/training sets, expert consensus, MRMC studies, or standalone performance is not applicable or not present in this regulatory submission for a dental abutment. The submission primarily relies on non-clinical testing to demonstrate that the changes from the predicate device do not negatively impact safety or effectiveness.

Here's a breakdown of the available information:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't present a table with specific numerical acceptance criteria and corresponding performance metrics for the SMARTBase abutments in a typical AI/software validation format. Instead, it describes general testing categories and their successful completion.

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

• Test Set Sample Size: Not explicitly stated for each test beyond "worst-case configuration" for mechanical fatigue and "worst case drivers" for screw torque.
• Data Provenance: Not explicitly stated (e.g., country of origin, retrospective/prospective). The testing appears to be primarily laboratory-based non-clinical testing.

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

• Not Applicable. This type of information is typically for devices involving human interpretation of data (e.g., imaging diagnosis). The current device is a physical dental implant abutment, and its "ground truth" is established through engineering and material testing standards.

4. Adjudication Method for the Test Set:

• Not Applicable. Adjudication methods like 2+1 or 3+1 are used for expert review of cases, typically in diagnostic or screening AI applications.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

• No. This type of study is for evaluating human performance with and without AI assistance in diagnostic tasks. The InterActive SMARTBase Abutments are physical devices, not an AI software meant to assist human readers.

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

• Not Applicable in the traditional sense of an AI algorithm. While software is mentioned (3Shape Abutment Designer™ Software), its role is in designing the physical component, not in making a standalone medical decision. The software itself underwent "verification and validation testing" to ensure it adheres to design rules and limitations for the physical device. The device itself (the abutment) does not operate as a standalone algorithm.

7. The Type of Ground Truth Used:

• The "ground truth" for this device revolves around engineering specifications, material properties, and established international standards (e.g., ISO 14801 for fatigue testing, ISO 10993 for biocompatibility, ISO 17665 for sterilization). The successful completion of these standardized tests serves as the evidence of meeting the necessary performance and safety benchmarks. There is no "expert consensus," "pathology," or "outcomes data" ground truth as would be relevant for a diagnostic or predictive device.

8. The Sample Size for the Training Set:

• Not Applicable. This refers to training data for machine learning models. This device is a physical implant component, not an AI model that requires a training set. The "abutment design library" is an engineering dataset, not a machine learning training set.

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

• Not Applicable. See point 8. The "ground truth" for the design library (if one were to interpret "training set" very loosely for a design context) would be established through engineering design principles, material science, and prior validated designs, ensuring the resulting physical abutments meet functional and safety requirements.

Anatotemp Anatomic Dental Implant Healing Abutments are compatible with the following implant systems:

The Anatotemp Anatomic Dental Implant Healing Abutment product line includes anatomically shaped temporary dental implant healing abutments that aid in creating an esthetic emergence through the gingiva during the healing period. Anatotemp Anatomic Dental Implant Healing Abutments are made of a polymethylmethacrylate biocompatible plastic and are held securely to an endosseous implant with a titanium abutment screw. Anatotemp Anatomic Dental Implant Healing Abutments are positioned well below the occlusal plane and are non-load bearing components that guide healing tissue.

Anatotemp Anatomic Dental Implant Healing Abutments are designed not to be in occlusion or sustain occlusal forces. Anatotemp Anatomic Dental Implant Healing Abutments come in six shapes that mimic original tooth shape at the gingival level and also exhibit a mild, biconcave shape interproximally that aids in creating an esthetic emergence through the gingiva during the healing period. Anatotemp Anatomic Dental Implant Healing Abutments exhibit anti-rotational connections that are compatible with many dental implant connections. Anatotemp Anatomic Dental Implant Healing Abutments are provided sterile, are single use, and are recommended for temporary placement of no longer than 180 days. Anatotemp Anatomic Dental Implant Healing Abutments are removed after dental implant healing (approximately 90-180 days) and replaced by the permanent abutment and crown.

The provided text describes a 510(k) premarket notification for the "Anatotemp Anatomic Dental Implant Healing Abutment." This document focuses on demonstrating substantial equivalence to a predicate device, rather than proving the device meets acceptance criteria through a clinical study with a specific test set, ground truth, and expert adjudication as one would find for a novel AI/imaging device.

Therefore, many of the requested criteria cannot be directly extracted from this document, as the regulatory pathway for this device (a dental implant healing abutment) does not involve the same type of performance evaluation as, for instance, an AI-powered diagnostic imaging system.

This document primarily relies on non-clinical testing (biocompatibility, chemical characterization, packaging, sterilization, shelf-life, and reverse engineering analysis) and comparison to a predicate device to establish substantial equivalence. It explicitly states that "Formal clinical studies were not conducted to support the claim for substantial equivalence to the predicate device."

Here's an attempt to address your points based on the provided text, highlighting where information is not applicable or not present for this type of device submission:

Acceptance Criteria and Device Performance for the Anatotemp Anatomic Dental Implant Healing Abutment

Since this is a 510(k) submission for a physical medical device (dental implant healing abutment) demonstrating substantial equivalence to a predicate, the "acceptance criteria" and "device performance" are typically related to material properties, biocompatibility, sterility, and functional equivalence, rather than diagnostic accuracy metrics as would be seen for an AI system. The study described is a series of non-clinical tests and a comparison.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are implicitly defined by the standards and characteristics required for demonstrating substantial equivalence to the predicate device, as well as the successful completion of the non-clinical tests. Performance is reported as meeting these standards.

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

• Test Set Sample Size: For the non-clinical testing, specific sample sizes are not explicitly stated for each test (e.g., number of animals for biocompatibility, number of packages/devices for sterilization/packaging). The document mentions "sample of the OEM implants were measured" for reverse engineering. This is not a "test set" in the context of an AI study.
• Data Provenance: Not applicable for this type of submission. The data is generated from internal company testing and contract lab testing, not patient data from a specific country or collected retrospectively/prospectively in a clinical setting.

3. Number of Experts Used to Establish Ground Truth and Qualifications

• Not applicable. This device does not use human "experts" to establish a ground truth for performance evaluation in the way an AI diagnostic imaging system would. The "ground truth" for the non-clinical tests is established by adherence to recognized international standards (ISO, ASTM, USP) and laboratory protocols.

4. Adjudication Method for the Test Set

• Not applicable. There is no "test set" in the context of human interpretation or diagnostic accuracy for this device.

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

• No. The document explicitly states: "Formal clinical studies were not conducted to support the claim for substantial equivalence to the predicate device..." An MRMC study is a type of clinical study, typically for diagnostic devices or AI assistance in interpretation.

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

• Not applicable. This is a physical medical device, not an algorithm.

7. The Type of Ground Truth Used

• The "ground truth" for this submission type is based on:
  • Regulatory Standards: Compliance with ISO, ASTM, and USP standards for biocompatibility, sterility, packaging, etc.
  • Engineering Specifications: Data derived from reverse engineering analysis of OEM implant systems to ensure compatibility.
  • Predicate Device Equivalence: The characteristics and performance of the legally marketed predicate device (Contour Healer).

8. The Sample Size for the Training Set

• Not applicable. This is not an AI/machine learning device. There is no "training set."

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

• Not applicable. There is no "training set."

GPS® Angled Abutments are designed to be used in support of a dental implant(s) to provide support for prosthetic restorations in a partially or completely edentulous patient. These abutments are designed to only receive a fabricated multi-unit bridge or overdenture. Abutments are intended for use in the mandible or maxilla. Implants can be indicated for immediate loading when good primary stability has been achieved and with appropriate occlusal loading.

GPS® Angled Abutments are designed to be used in conjunction with dental implant(s) to provide support for prosthetic restorations in a partially or completely edentulous patient. Abutments are intended for use in the mandible or maxilla. Implants can be indicated for immediate loading when good primary stability has been achieved and with appropriate occlusal loading. The proposed GPS® Angled Abutments are intended to provide extra prosthetic options currently unavailable to the clinician. The proposed abutments are intended to complement the cleared systems listed in Table 2 below. The proposed abutments have the same compatible implant interface specific to each implant system and platform size. The GPS® Angled abutments have the same coronal GPS Angled Top for all proposed GPS® Angled abutments. The GPS top has a superior outer radius at its coronal region that is identical to the primary predicate GoDirect implants (K090234 - Spectra System Dental Implants 2008). The proposed GPS® Angled abutments are a two-piece design having an identical lower piece with same interface features and angles as the reference predicate InterActive screw receiving angled abutments with a ball top (K130572 - InterActive/SwishPlus2 Implant System).

The provided text describes the 510(k) summary for the GPS® Angled Abutments, detailing their substantial equivalence to predicate devices. Here's a breakdown of the requested information:

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

The document does not explicitly state acceptance criteria in a quantitative format for specific performance metrics (e.g., "Must pass X N of force"). Instead, it confirms that the device meets the "equivalent or higher load" than the primary predicate device when tested according to FDA and ISO standards. The general acceptance criteria are:

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

• Sample Size: The document indicates that testing was performed on "the worst case abutment testing" (InterActive® /SwishActive GPS® Angled Abutment, 3.0 mm Platform) and "the proposed Angled GPS Abutments, primary predicate GoDirect implant and compatible comfort caps." However, it does not provide specific numerical sample sizes (e.g., how many abutments were tested for fatigue).
• Data Provenance: The studies are non-clinical performance data, likely conducted by Implant Direct Sybron Manufacturing, LLC which is located in Thousand Oaks, California, USA. The data is retrospective in the sense that it's generated for a regulatory submission rather than a prospective clinical trial. There's no mention of country of origin of data beyond the company's location.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

This section is not applicable as the document describes non-clinical performance data (mechanical, sterilization, biocompatibility testing) rather than a study requiring expert-established ground truth like image analysis or disease diagnosis.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

This section is not applicable for the same reason as point 3.

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

This section is not applicable. The document describes a medical device (dental abutment), not an AI diagnostic tool that would involve human readers or AI assistance.

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

This section is not applicable for the same reason as point 5.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

As mentioned in point 3, the studies are non-clinical performance evaluations. The "ground truth" for these tests are universally accepted scientific and engineering standards:

• Mechanical Testing: ISO 14801 standards for fatigue, and static compression tests. The ground truth is the physical failure or endurance limit of the material under applied forces.
• Sterilization: Sterility assurance level (SAL) of 10-6, as per AAMI/ANSI/ISO 17665-1 and ANSVAAMI ST79. The ground truth is the measurable absence of viable microorganisms.
• Biocompatibility: ISO 10993-5 standards for biological evaluation of medical devices. The ground truth is the measurable absence of toxic reaction from the devices.

8. The sample size for the training set

This section is not applicable. The device is a physical medical implant, not an algorithm that requires a training set.

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

This section is not applicable for the same reason as point 8.
