The superstructure is cemented to the TruBase in the lab. Use "RelyX Unicem 2Automix" as an adhesive extra orally to connect.

The provided text is a 510(k) summary for the TruAbutment DS and TruBase devices. It primarily focuses on demonstrating substantial equivalence to a predicate device (TruAbutment DS, K203649) and does not detail an acceptance criteria table with reported device performance in the manner of a clinical study. The text describes non-clinical testing performed, but not a study designed to prove the device meets acceptance criteria related to a specific clinical outcome or diagnostic accuracy.

Therefore, many of the requested items (acceptance criteria table, sample size for test/training sets, data provenance, expert ground truth, adjudication, MRMC studies, standalone performance, type of ground truth) are not applicable based on the content of this 510(k) summary, which is a premarket notification for a medical device primarily based on demonstrating substantial equivalence through engineering and mechanical testing, not clinical performance or AI algorithm validation studies.

However, I can extract the information provided regarding non-clinical testing for the devices.

Acceptance Criteria and Study for TruAbutment DS & TruBase

Based on the provided 510(k) summary, the "acceptance criteria" and "study" described are focused on non-clinical mechanical performance testing and demonstration of substantial equivalence to a predicate device, rather than a clinical study proving performance against specific clinical or diagnostic accuracy metrics with human or AI components.

Here's the relevant information extracted and presented based on the document:

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

The document does not provide a table with specific quantitative acceptance criteria alongside actual reported numerical performance results for the new devices in the context of a comparative study proving their performance against such criteria. Instead, it states that "The results of the above tests have met the criteria of the standard and demonstrated substantial equivalence with the reference devices." This implies a qualitative "met standard" outcome rather than specific numerical performance data.

The tables provided describe the design limits of the devices and compare them to the predicate device, not performance data from a test:

TruAbutment DS Design Parameters (Acceptance Criteria are implied by meeting these limits)

TruBase Design Parameters (Acceptance Criteria are implied by meeting these limits)

For mechanical performance, the document states:
"Mechanical performance testing was performed according to ISO 14801. For compatible OEM implant line, worst-case constructs were subjected to static compression and compression fatigue testing. The fatigue limit data for all other implant lines demonstrated the construct strengths to be sufficient for their intended use."

This confirms that the acceptance criteria for mechanical performance were "sufficient for their intended use" as defined by ISO 14801 and worst-case testing, but quantitative results are not provided.

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 for Test Set: The document mentions "worst-case constructs" were tested for mechanical performance, and "the entire system including all variations (all compatible implant bodies, dental abutments, and fixation screws)" was evaluated for MRI environment conditions. However, specific numerical sample sizes for these tests are not provided.
• Data Provenance: The data comes from non-clinical laboratory testing following international standards (ISO 14801, ISO 17665-1/2, ISO 10993 series). The country of origin and retrospective/prospective nature are not applicable as it's not a clinical data study.

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 is not applicable. The "ground truth" for this type of device (dental abutments) is established through adherence to engineering design specifications, material standards (ASTM F136), and performance under mechanical stress tests (ISO 14801), as well as compliance with sterilization and biocompatibility standards. It does not involve expert interpretation of images or clinical outcomes in the same way an AI diagnostic device would.

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

• This is not applicable as there is no human interpretation or subjective assessment of data requiring adjudication. Testing is based on objective measurements 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

• This is not applicable. The device is an endosseous dental implant abutment, not an AI diagnostic tool.

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

• This is not applicable. The device is a physical dental component, not an algorithm.

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

• The "ground truth" for validating these devices is adherence to engineering specifications, material properties, and performance standards (e.g., passing specific load-bearing and fatigue tests per ISO 14801, meeting biocompatibility requirements, maintaining dimensional accuracy). "Dimensional analysis and reverse engineering" were used to confirm compatibility.

8. The sample size for the training set

• This is not applicable. There is no "training set" as this is a physical medical device, not an AI/machine learning algorithm.

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

• This is not applicable for the reason above.

Summary of the Study Proving Device Meets Criteria (Based on Provided Text):

The "study" conducted was primarily non-clinical laboratory testing to demonstrate the mechanical performance, sterilization efficacy, and biocompatibility of the TruAbutment DS and TruBase devices. The objective was to show substantial equivalence to an existing legally marketed device (TruAbutment DS, K203649) by proving that the new devices meet established design limits and performance standards relevant to dental implant abutments.

• Mechanical Testing: Performed on "worst-case constructs" according to ISO 14801 for static compression and compression fatigue. The outcome was that "construct strengths [were] sufficient for their intended use."
• Sterilization Testing: Performed per ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010.
• Biocompatibility Testing: Performed per ISO 10993-1:2009, ISO 10993-5:2009, and ISO 10993-10:2010.
• MRI Environment Evaluation: A non-clinical worst-case MRI review was done using scientific rationale and published literature to assess magnetically induced displacement force and torque.
• Dimensional Analysis and Reverse Engineering: Conducted on the implant-to-abutment connection platform to assess critical design aspects and tolerances, confirming compatibility.

The overall conclusion was that the devices "met the criteria of the standard and demonstrated substantial equivalence with the reference devices," thus indicating they met their implied acceptance criteria for safety and performance as medical devices. Clinical testing was explicitly stated as "not necessary."

The provided text is a 510(k) summary for the TruAbutment DS and TruBase devices, which are endosseous dental implant abutments. It primarily focuses on demonstrating substantial equivalence to a predicate device rather than presenting detailed "acceptance criteria" and results from a study proving the device meets those specific criteria in the way one might find for a novel AI/software medical device.

The document discusses performance in terms of mechanical resistance and dimensional compatibility to ensure long-term functional performance with dental implants. However, it does not outline distinct "acceptance criteria" that are then verified by a specific study with a defined sample size, ground truth, or expert adjudication as typically seen in AI/ML validation. Instead, it relies on demonstrating compliance with recognized standards and comparability to a predicate device.

Given the information provided, here's an attempt to answer the questions based on the context of this 510(k) summary, interpreting "acceptance criteria" as the performance expectations set by the applicable standards and "study" as the non-clinical testing performed:

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

The document doesn't explicitly state "acceptance criteria" in a tabular format with corresponding reported performance for a comparative AI study. Instead, it refers to compliance with established standards for dental implant abutments. The closest equivalent to "acceptance criteria" for the mechanical performance is meeting the requirements of ISO 14801.

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

The document does not specify a "test set" sample size in the context of an AI/ML model for image analysis or diagnostics. The testing described is primarily non-clinical mechanical testing, dimensional analysis, and biocompatibility testing of physical devices.

• Sample Size: Not specified in terms of "number of cases" or "patients" for a diagnostic study. For mechanical testing, samples would be physical devices/constructs. The number of samples for ISO 14801 fatigue testing is typically defined by the standard itself (e.g., typically 3 samples for static and 15 samples for fatigue for each configuration).
• Data Provenance: Not applicable in the sense of patient data or images. The "data" comes from physical testing of manufactured devices.

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

This information is not applicable to the type of device and testing described. The "ground truth" for mechanical properties is established by physical measurement against engineering specifications and performance under defined load conditions, not by expert human interpretation.

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

Not applicable. There is no human interpretation or subjective assessment involved that would require an adjudication method.

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. The device is a physical 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

Not applicable. The device is a physical dental implant abutment, not an AI algorithm.

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

The "ground truth" for this medical device is based on engineering specifications, material science standards (e.g., ASTM F136), and mechanical testing standards (e.g., ISO 14801). For example, mechanical strength and fatigue life are measured directly, and dimensional compatibility is assessed against design tolerances.

8. The sample size for the training set

Not applicable. This is not an AI/ML device that requires a training set. The "design" of the abutments is based on CAD/CAM systems informed by engineering principles, not machine learning from large datasets.

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

Not applicable. As this is not an AI/ML device, there is no "training set" or "ground truth for the training set" in the context of machine learning. The knowledge base for the CAD/CAM design and manufacturing is derived from established dental and engineering principles, material science, and regulatory standards.

The superstructure is cemented to the TruBase S in the lab. Use "RelyX Unicem 2Automix" as an adhesive extra orally to connect.
  TruBase S is provided non-sterile therefore must be sterilized after the cementation of the customized superstructure on the TruBase S.

The provided text is a 510(k) summary for a dental device, TruAbutment DS and TruBase S. It primarily focuses on demonstrating substantial equivalence to predicate devices based on design specifications, materials, and non-clinical testing (mechanical and biocompatibility).

This document does not contain information about studies involving human-in-the-loop performance, expert ground truth establishment, or clinical effectiveness studies in the context of AI/ML device performance. The "acceptance criteria" discussed are related to the mechanical properties and biocompatibility of the physical dental abutment and base, rather than the performance of an AI/ML algorithm.

Therefore, many of the requested points, such as sample size for test/training sets, experts for ground truth, adjudication methods, MRMC studies, or standalone algorithm performance, cannot be extracted from this document as they are not relevant to the type of device and testing described.

However, I can provide information based on the mechanical and material testing criteria that are present.

Here's an analysis of the provided text in relation to your request, with a clear indication of what information is not available:

Information Pertaining to Device Acceptance (Mechanical/Biocompatibility):

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

   The document describes design limitations and states that non-clinical testing (fatigue and biocompatibility) met the criteria of the standard, demonstrating substantial equivalence. It does not provide specific numerical performance results for the acceptance criteria, but rather states whether the device "met the criteria of the standard" (ISO 14801:2016 for fatigue, ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010 for sterilization, and ISO 10993 series for biocompatibility).

   For TruAbutment DS:

   Design Parameter	Design Limit (Acceptance Criteria)	Reported Performance (Qualitative)
   Abutment Angle	0~25°	Met design limit
   Cuff Height	0.5~6.0mm	Met design limit
   Diameter at abutment/implant interface	Ø3.5mm~Ø8.0mm	Met design limit
   Minimum Thickness	0.4 mm	Met design limit
   Length of abutment post	4~7 mm	Met design limit

   For TruBase S (Zirconia Superstructure):

   Design Parameter	Design Limit (Acceptance Criteria)	Reported Performance (Qualitative)
   Abutment Angle	0~15°	Met design limit
   Cuff Height	0.5~5 mm	Met design limit
   Diameter at abutment/implant interface	Ø5.0mm~Ø8.0mm	Met design limit
   Minimum Thickness	0.4 mm	Met design limit
   Length of abutment post	4~6 mm	Met design limit

   Non-Clinical Testing:

   Acceptance Criteria (Standard)	Reported Performance
   Fatigue Test (ISO 14801:2016)	"The fatigue limit data for all other implant lines demonstrated the construct strengths to be sufficient for their intended use."
   End User Steam Sterilization Test (ISO 17665-1:2006, 17665-2:2009, ANSI/AAMI ST79:2010)	"The results of the above tests have met the criteria of the standard, and demonstrated the substantial equivalence with the predicate device."
   Biocompatibility (ISO 10993-5:2009, ISO 10993-10:2010)	"The results of the above tests have met the criteria of the standard, and demonstrated the substantial equivalence with the predicate device."

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

   • Sample Size: Not explicitly stated for specific tests (e.g., how many abutments were fatigued). The document mentions "worst-case constructs" were subjected to testing.
   • Data Provenance: Not specified (e.g., country of origin). The studies appear to be non-clinical (laboratory testing) rather than human subject data. The studies are retrospective as they leverage data from previous 510(k) clearances (K152559).

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

   • Not applicable. The "ground truth" here is based on engineering standards (e.g., ISO 14801 for mechanical properties, ISO 10993 for biocompatibility) and direct physical measurements, not expert human interpretation of medical images or clinical outcomes.

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

   • Not applicable. This relates to human expert review and consensus, which is not part of the physical and mechanical testing described.

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 a physical dental implant component, not an AI/ML diagnostic or assistive 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/ML algorithm. It's a medical device that is CAD/CAM manufactured.

7. The type of ground truth used:

   • For mechanical performance: Compliance with ISO 14801:2016 standard. This involves objective physical measurements and material science.
   • For sterilization: Compliance with ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010 standards.
   • For biocompatibility: Compliance with ISO 10993-5:2009, ISO 10993-10:2010 standards.

8. The sample size for the training set:

   • Not applicable. This is not an AI/ML algorithm that requires a "training set" in the computational sense. The "training" for manufacturing is implied through the "TruAbutment-validated milling center."

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

   • Not applicable. As above, no computational "training set" is described. The manufacturing process relies on validated design parameters and material specifications.

In summary, this 510(k) submission successfully demonstrates substantial equivalence based on engineering design parameters, material properties, and adherence to established mechanical and biological safety standards for a physical dental implant component. It does not involve AI/ML technology or associated human-in-the-loop performance studies.

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and the data provenance
The document does not explicitly state the exact sample size (number of abutments or implants) used for the non-clinical mechanical and dimensional tests. It mentions "worst-case constructs" for fatigue testing.
Data provenance: The testing was conducted by the manufacturer (TruAbutment Inc.) as part of their 510(k) submission to the FDA, presumably in the USA (where the company is based). The data is retrospective as it was generated specifically for this submission.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not applicable. The "ground truth" for this device's performance is established by meeting recognized international and national standards (ISO, FDA guidance) through non-clinical laboratory testing, not by expert consensus on clinical cases.

4. Adjudication method for the test set
This is not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or studies involving human interpretation of medical images. The studies performed for this device were non-clinical laboratory tests.

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
No, an MRMC comparative effectiveness study was not done. This device is a physical dental implant abutment, not an AI or imaging diagnostic tool that would involve human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. This device is a physical medical device, not an algorithm. The "standalone" performance is assessed by its mechanical integrity and biocompatibility when used as intended.

7. The type of ground truth used
The "ground truth" used for this device is based on established engineering and materials science principles and validated standards:

• Mechanical Performance: Defined by the specified fatigue limits and static load capabilities as per ISO 14801 and FDA guidance thresholds for dental implant abutments.
• Biocompatibility: Defined by the absence of adverse biological reactions as per ISO 10993 series standards.
• Dimensional Accuracy: Defined by precise measurements confirming compatibility with target implant systems.

The provided document describes the FDA 510(k) clearance for the TruAbutment DS, a patient-specific CAD/CAM abutment. It does not contain information typically found in an AI/ML device approval, such as acceptance criteria related to classification metrics (e.g., sensitivity, specificity, AUC), sample size for test sets (in the context of AI models), number of experts for ground truth, adjudication methods, MRMC studies, standalone performance of an algorithm (as this is a physical device, not an algorithm), or information about training datasets.

The "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this document refer to the non-clinical testing performed for the physical dental abutment device, primarily focusing on its mechanical performance and compatibility with existing implants.

Here's the information parsed from the document based on the device type:

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

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

• Sample Size for Test Set: The document mentions "finished assembled implant/abutment systems of the worst-case scenario" for fatigue testing. It does not specify a numerical sample size but implies a representative selection for worst-case evaluation. For sterilization and biocompatibility, the tests were "performed for reference device K152559 and leveraged for the subject device," without specifying its sample size.
• Data Provenance: Not applicable in the context of clinical data for AI/ML. The tests are non-clinical, performed in a lab setting.

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

• Not applicable. The ground truth for this physical device is based on objective engineering standards (ISO standards, dimensional measurements, material properties), not expert interpretation of medical images or conditions.

4. Adjudication method for the test set:

• Not applicable, as this is not a study requiring adjudication of interpretations.

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. TruAbutment DS is a physical dental implant component, not an AI-assisted diagnostic or prognostic tool.

The provided text describes the regulatory submission for the TruAbutment DS, a patient-specific CAD/CAM abutment for dental implants. The core of the submission is to demonstrate "substantial equivalence" to existing predicate devices, rather than proving effectiveness through a traditional clinical study with defined acceptance criteria and effect sizes.

Therefore, the information you're asking for regarding acceptance criteria, sample sizes for test/training sets, expert adjudication, MRMC studies, standalone performance, and ground truth establishment is not directly applicable or available in this document in the way it would be for a machine learning or AI-driven device performance study.

This document focuses on non-clinical testing to demonstrate the physical performance and compatibility of the device.

Here's how to address your request based on the provided document:

Acceptance Criteria and Device Performance

The "acceptance criteria" here are defined by the relevant ISO standards and FDA guidance for dental implant abutments, specifically related to mechanical integrity and biocompatibility, as well as dimensional compatibility with specified implant systems. The "device performance" is reported as having met these criteria.

Table of Acceptance Criteria and Reported Device Performance (Based on Non-Clinical Testing):

Study Details (as inferable from the document):

Since this is a submission for a physical medical device (dental abutment) and a demonstration of substantial equivalence rather than a novel AI/ML algorithm, most of your specific questions about data sets, experts, and MRMC studies do not apply.

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

   • Sample Size (Test Set): Not explicitly stated as a "test set" in the context of an algorithm. The "test set" here refers to the physical samples of the TruAbutment DS device and compatible implant systems that underwent non-clinical laboratory testing (fatigue, biocompatibility, sterilization, dimensional analysis). The document mentions "worst-case scenario" testing (smallest diameter with maximum angulation), implying a targeted selection of test articles rather than a large, randomized "test set" as understood in a data science context. The exact number of samples for each test (e.g., number of abutments for fatigue testing) is not provided.
   • Data Provenance: The document does not specify the country of origin of the data beyond the standards being international (ISO, ANSI/AAMI). The testing was "non-clinical testing," performed in a laboratory setting. It is retrospective in the sense that the results are being leveraged for a new device submission (K172304), and some tests were performed for a prior predicate device (K152559) and leveraged.

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

   • Not Applicable. "Ground truth" in this context refers to the validated performance of a physical device against established engineering and biological standards. This is determined by laboratory measurements and adherence to specified test protocols, not by expert consensus on data annotations for an AI model.
   • The "experts" would be the engineers and scientists conducting and validating the lab tests according to the standards. Their qualifications are not specified but would be implicit in their ability to conduct such highly technical and regulated testing.

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

   • Not Applicable. This concept is relevant for reconciling discrepancies in human annotations or interpretations for ground truth establishment in AI/ML. For physical device testing, the "ground truth" is defined by the technical specifications and the results of validated laboratory tests.

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:

   • No, not done. This type of study (MRMC) is for evaluating diagnostic performance of AI-assisted human readers. The TruAbutment DS is a physical medical device (dental abutment), not an AI/ML diagnostic tool. The document explicitly states: "Clinical testing was not necessary to establish substantial equivalency of the device."

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

   • Not Applicable. As above, this is not an AI/ML algorithm. Its "standalone" performance means its physical properties and mechanical integrity, which were evaluated through non-clinical laboratory tests.

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

   • The "ground truth" for this device's performance is established by engineering standards (ISO 14801), biocompatibility standards (ISO 10993 series), sterilization standards (ISO 17665, ANSI/AAMI ST79), and dimensional analysis via reverse engineering. These are objective, empirically measured outcomes from laboratory testing, not human-derived consensus or clinical outcomes data.

7. The sample size for the training set:

   • Not Applicable. There is no "training set" in the context of an AI/ML algorithm for this device. The design and manufacturing process for the TruAbutment DS would have been developed iteratively (similar to an engineering "training phase"), but not with a structured data "training set" in the AI sense.

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

   • Not Applicable. See point 7. The "ground truth" during the development of such a device would be based on design specifications, material properties, and iterative engineering testing to ensure the device meets its intended functional requirements and complies with relevant standards.

Here's a breakdown of the acceptance criteria and study information based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't explicitly state "acceptance criteria" in a quantitative table format for the device's main function (prosthetic rehabilitation). Instead, it focuses on demonstrating substantial equivalence to a predicate device through various non-clinical tests. The "performance" is implicitly deemed acceptable if these tests meet the standards and demonstrate equivalence.

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

• Sample Size: Not explicitly stated for specific tests (e.g., how many abutments were fatigued). The document refers to testing "finished assembled implant/abutment systems of the worst-case scenario."
• Data Provenance: The studies are non-clinical (laboratory tests). There is no mention of country of origin for test data beyond the general context of the company (TruAbutment Inc., USA). The studies are inherently "retrospective" in the sense that they are laboratory evaluations, not studies on past patient data.

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

This information is not applicable (N/A) as the study is non-clinical (mechanical, sterilization, biocompatibility testing) and does not involve human interpretation or subjective assessment that would require expert ground truth establishment in the traditional sense. The "ground truth" is defined by the technical standards (e.g., ISO 14801) themselves.

4. Adjudication Method for the Test Set

This information is not applicable (N/A) for the same reasons as point 3. Testing against standards doesn't typically involve adjudication of ground truth by multiple experts.

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 information is not applicable (N/A). The TruAbutment DS is a physical medical device (patient-specific CAD/CAM abutment), not an AI/software device that involves human readers or image interpretation.

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

This information is not applicable (N/A). As mentioned above, this is a physical medical device, not an algorithm or AI system.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

The ground truth for the non-clinical tests is established by technical standards and specifications. For example:

• Mechanical performance: Defined by the requirements of ISO 14801:2007 for dental implants.
• Sterilization: Defined by ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010.
• Biocompatibility: Defined by ISO 10993-1:2009, ISO 10993-5:2009, and ISO 10993-10:2010.
• Dimensional accuracy: Established by engineering specifications and comparison to OEM implant and abutment dimensions.

8. The Sample Size for the Training Set

This information is not applicable (N/A). This is a physical medical device, not an AI/machine learning model that requires a training set.

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

It is compatible with all diameters of the Osstem TS Fixture System which consists of Mini (2.08mm) and Regular (2.48mm) interface sizes.

All digitally designed abutments and/or coping for use with the TruAbutments are intended to be sent to a TruAbutment-validated milling center for manufacture.

The TruAbutment DS system includes custom abutments which are placed into the dental implant to provide support for a prosthetic restoration. The subject abutments are indicated for screwretained restorations. The custom abutment and abutment screw are made of Titamium grade Ti-6A1-4V ELI (meets ASTM Standard F-I 36) for Osstem TS Fixture System (K121995) which consists of both Mini and Regular interface sizes. Each custom abutment is supplied with two identical screws which are used for:

• (1) For fixing into the endosseous implant
• (2) For dental laboratory use during construction of related restoration.

The abutment is placed over the implant shoulder and mounted into the implant with the provided screw. The design and manufacturing of the custom abutments take into consideration the shape of final prosthesis based on the patient's intra-oral indications using CAD/CAM system during the manufacturing. All manufacturing processes of TruAbutment DS are conducted at the TruAbutment milling center and provided to the authorized end-user as a final patient-specific abutment.

Here's a summary of the acceptance criteria and study information for the TruAbutment DS, based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state numerical acceptance criteria in terms of performance metrics (like accuracy, sensitivity, specificity, etc.) for the device itself. Instead, the "acceptance criteria" are implied by meeting various regulatory and engineering standards. The reported device performance is therefore described in terms of compliance with these standards and demonstrated substantial equivalence to a predicate device.

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

• Sample Size for Test Set: The document describes non-clinical testing for mechanical and material properties. For the Fatigue Test (ISO 14801:2007), it states "testing finished assembled implant/abutment systems of the worst case scenario, (smallest diameter with maximum angulation)." While the exact number of samples tested isn't specified, this indicates a specific test configuration rather than a large statistical sample of diverse cases. The other tests (sterilization, biocompatibility) typically involve multiple samples to demonstrate compliance, but specific numbers are not provided.
• Data Provenance: Not applicable in the context of clinical data for a medical device. This is a technical performance study, not a study involving patient data.

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

Not applicable. The ground truth for this device (an implant abutment) is based on engineering standards, material specifications, and physical measurements, rather than expert consensus on medical imaging or clinical diagnoses.

4. Adjudication Method for the Test Set

Not applicable. This is not a study requiring human adjudication of results in the way a diagnostic imaging study would. The "adjudication" is essentially the determination of whether the device met the specified engineering and material performance 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

No. This is not an AI-based device or a diagnostic tool that would involve human readers. It is a custom dental implant abutment.

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

No. This device is a physical medical device (an abutment), not an algorithm or software. It is designed using CAD/CAM, but the "performance" discussed is related to its physical properties and mechanical compatibility.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance evaluation is primarily:

• Engineering Standards: Compliance with international standards such as ISO 14801 (Fatigue), ISO 10993 series (Biocompatibility), and ISO 17665 series/ANSI/AAMI ST79 (Sterilization).
• Material Specifications: Adherence to ASTM Standard F-I 36 for Ti-6A1-4V ELI titanium.
• Dimensional Specifications: Measured dimensions and tolerances to ensure compatibility with the Osstem TS Fixture System.
• Predicate Device Performance: The established safety and effectiveness of the legally marketed predicate device (ET SmartFit Abutment K123627) serves as a benchmark for demonstrating substantial equivalence.

8. The Sample Size for the Training Set

Not applicable. The device is not an AI algorithm that requires a training set of data. Its design and manufacturing process utilize CAD/CAM, but the "training set" concept doesn't apply to the device's physical evaluation.

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

Not applicable, as there is no "training set." The CAD/CAM system used for design would operate based on established anatomical parameters, prosthetic requirements, and material properties, rather than being "trained" on a dataset in the AI sense.
