Geo Abutments are intended for use to support a prosthetic device in a partially or completely edentulous patient. They are intended to support a single-unit or multi-unit cement-retained prosthesis in the mandible or maxilla. Geo Abutments are compatible with the following implants. All digitally designed custom abutments for use with Geo Abutments are to be sent to a GeoMedi Co. Ltd. validated milling center for manufacture.

The purpose of this submission is to obtain marketing clearance for Geo Abutment from GeoMedi Co., Ltd. a line of titanium base abutments (identified as Multibase) and machinable blank abutments (identified as CMFit) to interface with compatible dental implants from four (4) manufacturers, and a total of seven (7) implant-abutment connections. The compatible implant body diameters range from 3.0 mm to 8.0 mm. The subject device prosthetic platform diameters range from 4.0 mm to 4.6 mm. All patient-specific abutments prepared from subject device Geo Abutment are to be manufactured at a GeoMedi validated milling center.

Geo Multibase abutments are two-piece abutments in which the Geo Multibase Abutment comprises the first part of the two-piece abutment and a patient-specific zirconia superstructure comprises the second part; the assembly becoming a final finished medical device after cementation of the superstructure on the subject device abutment. They are provided in straight designs, and two (2) connection types: for single unit prostheses (engaging connection) and for bridge or multi-unit prostheses (non-engaging connection). They are not intended for angulation correction, as the design parameters for the superstructure are restricted to straight abutments only.

These abutments are made of titanium alloy (Ti-6Al-4V) with a titanium nitride (TiN) coating on the coronal portion of the external surface, not including the implant-abutment interface.

The Geo Multibase abutment and corresponding zirconia superstructure are provided to the clinician either with the superstructure cemented to the abutment by the dental laboratory or separately, for the clinician to bond together chairside, using the cement required in the labeling (3M ESPE RelyX Unicem bonding cement, cleared in K022476 as RelyX RMGIP).

All patient-specific custom zirconia superstructure fabrication is by prescription on the order of the clinician.

The design parameters for zirconia superstructures to be used with Geo Multibase abutments are:

• Minimum wall thickness – 0.5 mm
• Minimum cementable post height for single-unit restoration – 4.0 mm (minimum cementable post height for single-unit restoration is defined as the height above the restorative margin)
• Minimum gingival height of the superstructure – 0 mm (Geo Multibase abutments have minimum gingival height of 1.0 mm)
• Maximum gingival height – 5.0 mm
• Maximum angle – 0° (straight only)

All zirconia copings (superstructures) for use with the subject device Geo Multibase abutment will be made at a GeoMedi Co., Ltd. validated milling center under FDA quality system regulations, and the material will conform to ISO 13356, Implants for surgery – Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP).

Geo CMFit abutments are cylindrical titanium alloy abutments designed to be used for fabrication of a one-piece, all titanium patient-specific abutment by a CAD/CAM process. The portion of the abutment available for milling is either 9.9 mm in diameter by 20 mm in length or 13.9 mm in diameter by 20 mm in length. Geo CMFit abutments are available in engaging and non-engaging connections.

All patient-specific abutment fabrication is by prescription on the order of the clinician. The design parameters for all CMFit patient-specific abutments are:

• Minimum wall thickness – 0.65 mm
• Minimum cementable post height for single-unit restoration – 4.0 mm (minimum cementable post height for single-unit restoration is defined as the height above the restorative margin)
• Minimum gingival height – 0.5 mm
• Maximum gingival height – 5.0 mm
• Maximum angle – 30°

Manufacture of the Geo Abutment CMFIT patient-specific abutment is to be performed at an GeoMedi Co., Ltd. validated milling center.

The provided text is a 510(k) clearance letter for a dental implant abutment, not an AI/ML medical device where performance characteristics like sensitivity, specificity, or reader studies are typically discussed.

The document primarily focuses on demonstrating substantial equivalence to predicate devices through:

• Indications for Use (IFU) comparison: Showing that the intended use of the Geo Abutment is the same as already cleared devices (supporting prosthetic devices in edentulous patients, compatible with various implants).
• Technological characteristics comparison: Detailing similarities in design, materials (titanium alloy, TiN coating, zirconia for superstructures), manufacturing processes (CAD/CAM, milling center), mechanical properties, and sterilization methods.
• Non-clinical performance data: This section lists types of tests conducted (e.g., mechanical testing per ISO 14801, shear/tension testing per ASTM F1044/F1147, sterilization validation per ISO 17665-1/2, biocompatibility per ISO 10993-5/12) to ensure the device meets safety and performance standards equivalent to the predicate. However, it does not provide acceptance criteria or specific numerical results from these tests. It only states that these tests were done to "demonstrate that the subject devices... have sufficient strength for the intended use" and "characterize the mechanical properties."

Therefore, based on the provided document, I cannot fulfill your request for:

1. A table of acceptance criteria and the reported device performance: This detailed information is typically part of the test reports submitted to the FDA, but not usually summarized in the publicly available 510(k) clearance letter or summary in this level of detail (i.e., the specific pass/fail thresholds and the measured values for each test). The document only states what was tested and the conclusion that it demonstrated "sufficient strength."
2. Sample sizes used for the test set and the data provenance: This information is not present in the 510(k) summary. These details would be in the specific test protocols and reports.
3. Number of experts used to establish the ground truth... and their qualifications: This is not applicable as this is a physical device, not an AI/ML diagnostic aid requiring human expert annotation for ground truth.
4. Adjudication method for the test set: Not applicable for this type of device.
5. MRMC comparative effectiveness study: Not applicable for a physical dental abutment. This is typically for AI/ML diagnostic devices.
6. Standalone (algorithm only without human-in-the-loop performance): Not applicable for a physical device.
7. The type of ground truth used: For a physical device like a dental abutment, "ground truth" relates to material properties, mechanical strength, dimensional accuracy, and biocompatibility, as demonstrated through engineering tests and material characterization, not clinical outcomes or expert consensus in an AI sense. The document refers to ISO and ASTM standards, which define the test methods and what constitutes acceptable performance (the "ground truth" for material and mechanical properties).
8. The sample size for the training set: Not applicable. This is not an AI/ML device.
9. How the ground truth for the training set was established: Not applicable.

In summary, the provided document demonstrates substantial equivalence for a physical dental device through comparison to predicate devices and adherence to established engineering and material standards, rather than through clinical study formats typically seen for AI/ML diagnostic tools.

To answer your question, if this were an AI/ML device document, the "acceptance criteria" and "reported device performance" would typically be found in sections describing performance metrics like:

• Sensitivity, Specificity, Accuracy
• Area Under the Receiver Operating Characteristic (ROC) Curve (AUC)
• Positive Predictive Value (PPV), Negative Predictive Value (NPV)
• F-score or Dice coefficient (for segmentation tasks)
• Comparison to a "clinical standard of care" or "expert performance."

And the "study that proves the device meets the acceptance criteria" would be a clinical validation study (often a retrospective or prospective reader study or a standalone algorithm performance study) with clearly defined ground truth, reader qualifications, and statistical analysis. None of these elements are present because the device is a physical dental abutment.

Therefore, many of the requested items related to AI/ML device performance (like acceptance criteria for diagnostic metrics, sample size for test sets, data provenance, expert qualifications, adjudication methods, MRMC studies, standalone performance, and training set details) are not applicable to this submission.

The acceptance criteria and supporting "study" (non-clinical data) for this device are related to its mechanical performance, biocompatibility, and integration within the digital workflow, demonstrating that the expanded components maintain the safety and effectiveness of the previously cleared predicate devices.

Here's a breakdown based on the information provided and the non-applicability of AI/ML-specific questions:

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

Since this is not an AI/ML diagnostic device, the acceptance criteria are not in terms of traditional diagnostic metrics (sensitivity, specificity, AUC). Instead, they are related to material properties, mechanical integrity, and the digital workflow's accuracy.

• Abutment design library validated to demonstrate established design limitations are locked and cannot be modified by the user. (Implies successful implementation and verification of design constraints.) |
  | CAM Restriction Zones / Manufacturing Accuracy | - Validation testing of CAM restriction zones conducted, including verification to show avoidance of damage or modifications of the connection geometry, and locking of restriction zones from user editing in CAM software. (Implies successful validation to ensure manufacturing precision and prevent damage.) |
  | Material Conformance | - Zirconia materials conform to ISO 6872.
• Titanium alloy conforms to ASTM F136.
• Co-Cr-Mo alloy conforms to ASTM F15337. (Implies materials meet standards.) |
  | Physical Dimensions | - Device encompasses the same range of physical dimensions as the predicate device. (Implies dimensional equivalence.) |

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: Not explicitly stated in terms of a "test set" for diagnostic performance. The validation involved physical testing of components (e.g., fatigue testing) and software verification. The specific number of abutments or digital design instances used for these non-clinical tests is not detailed in this summary.
• Data Provenance: Not applicable in the context of patient data for an AI/ML device. The "data" here refers to engineering and material testing results, likely conducted in controlled lab environments (implied to be in accordance with international standards like ISO and ASTM). The manufacturer is Terrats Medical SL, in Spain, so testing would likely originate from their facilities or contracted labs.

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)

Not applicable. This is not a diagnostic device requiring expert interpretation for ground truth. The "ground truth" for this device relates to engineering specifications and material science.

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

Not applicable. This is not a diagnostic device involving expert review adjudication.

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 not an AI-assisted diagnostic tool.

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.

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

For this device, the "ground truth" is based on:

• Engineering Specifications: Defined design parameters (e.g., minimum wall thickness, post height, angulation limits).
• Material Standards: Conformance to international standards such as ASTM F136, ISO 6872.

The document does not contain information about acceptance criteria or performance data for an AI/ML-based device, nor does it detail a clinical study involving human readers or expert consensus for ground truth.

Therefore, for the information requested in your prompt, I can only extract what is presented in the document, which pertains to the non-AI aspects of device acceptance and testing. Many of the points specifically refer to AI/MRMC studies, which are not applicable to this document.

Here's an analysis based on the provided text:

Device Description and Purpose:
The device is "Medentika CAD/CAM Abutments," which are dental implant abutments. The primary purpose of this submission is to expand the fabrication options for patient-specific final abutments from a "validated milling center" to a "digital dentistry workflow" that integrates CAD/CAM software and milling machines. It also adds new sizes and OEM compatibilities.

Study Type:
This is a pre-market notification (510(k)) submission seeking substantial equivalence to existing legally marketed devices. It relies heavily on non-clinical performance data to demonstrate that the new manufacturing workflow and expanded compatibilities do not raise new questions of safety or effectiveness.

Analysis of Requested Information (based on the provided document):

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

The document outlines various performance tests conducted to demonstrate substantial equivalence, but it does not explicitly present a "table of acceptance criteria" with corresponding "reported device performance." Instead, it states that the tests demonstrate sufficient strength or ensure accuracy and reliability.

Here's a summary of the performance tests and their implied purpose:

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

• Sample Size for Test Set: The document does not specify numerical sample sizes for any of the non-clinical tests (e.g., how many abutments were mechanically tested, how many software validation tests were run). It simply states that "testing was conducted" or "validation was performed."
• Data Provenance: The document does not explicitly state the country of origin of the data or whether the studies were retrospective or prospective. Given the nature of pre-market non-clinical testing for medical devices, these are typically prospective laboratory tests conducted by the manufacturer or accredited testing facilities. The manufacturer is Medentika® GmbH (Huegelsheim, Germany), suggesting the testing likely occurred in Germany or at internationally recognized labs.

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 provided document. The ground truth for this device is established through engineering specifications, material standards (e.g., ASTM F136), and validated manufacturing processes, not through human expert consensus on diagnostic images.

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

This information is not applicable to the provided document, as it describes non-clinical engineering and manufacturing validation, not a multi-reader clinical study for AI.

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 to the provided document. This device is a physical dental abutment and its associated CAD/CAM workflow, not an AI-based diagnostic tool that would require human reader studies. The document explicitly states: "No clinical data were included in this submission."

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

This information is not applicable to the provided document. While the device utilizes CAD/CAM software and milling machines, it is a physical product manufactured through a workflow, not a standalone AI algorithm whose performance needs to be assessed in isolation. The software functions as a design and manufacturing aid, not a diagnostic or decision-making algorithm.

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

The "ground truth" in this context refers to established engineering and material standards:

• Standards Compliance: Adherence to ISO standards (e.g., ISO 14801 for mechanical strength, ISO 10993 for biocompatibility, ISO 17665 for sterilization).
• Dimensional Accuracy: Verification against established design parameters and compatibility specifications for dental implants (e.g., OEM implant body and abutment dimensions).
• Material Specifications: Conformance to ASTM F136 for titanium alloy and specifications for zirconia and cement.
• Software Design Parameters: The "ground truth" for the CAD software validation is the pre-defined maximum and minimum design parameters that the software must enforce.

8. The sample size for the training set:

This information is not applicable to the provided document. The "device" in question is a physical dental abutment and its manufacturing workflow, not an AI/ML model that requires a training set. The CAD/CAM software itself is validated, not "trained" on a dataset in the AI sense.

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

This information is not applicable to the provided document for the same reasons as point 8.

The MegaGen Dental Implant Abutment includes several components: Healing Abutment, Temporary Cylinder, EZ Post Abutment, EZ Post Cylinder, CCM Abutment, Gold Abutment, Octa Abutment, ZrGEN Abutment, TiGEN Abutment, AXA Abutment (Straight and Angled Types), and Abutment Screw. These components are made of materials such as Ti-6Al-4V-ELI, POM, Co-Cr-Mo alloy, and gold alloy, and are offered with machined or anodized surfaces. Some components are supplied sterile, while others are non-sterile and require sterilization by the user. They are intended for single use. The device provides prosthetic support for dental restorations on endosseous dental implants.

The provided text is a 510(k) summary for the MegaGen Dental Implant Abutment, seeking clearance based on substantial equivalence to predicate devices. It does not contain information about a study that proves the device meets specific acceptance criteria in terms of clinical performance, diagnostic accuracy, or effectiveness with human readers.

Instead, the document details a comparison of the subject device (MegaGen Dental Implant Abutment) with various predicate and reference devices, focusing on technical characteristics, materials, and design. The "acceptance criteria" referred to in the document are primarily related to meeting the characteristics of the predicate devices and demonstrating that any differences do not affect the fundamental function or safety of the device. The "study" that "proves" the device meets these criteria is a non-clinical testing summary, including biocompatibility, sterilization validation, accelerated shelf-life, pyrogen/endotoxin testing, performance testing (ISO 14801), and MR compatibility.

Therefore, many of the requested fields cannot be answered directly from the provided text as they pertain to clinical or diagnostic performance studies involving human subjects or AI algorithms, which are not described here.

Here's a breakdown of the information that can be extracted, and where the requested information is not available:

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

The document does not explicitly present a table of acceptance criteria with corresponding device performance for each component in a consolidated manner. Instead, it discusses "similarities" and "differences" compared to predicate/reference devices, and states that "test results met the pre-set criteria" for performance testing (ISO 14801) and that biocompatibility and sterilization have been validated.

Below is a summarized representation of the comparison for one component (Healing Abutment) as an example, to illustrate the type of comparison presented in the document. The "acceptance criteria" are implied by the characteristics of the predicate/reference devices, and "reported device performance" refers to the subject device's characteristics or the outcome of non-clinical tests.

Example for Healing Abutment:

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

• Test Set Sample Size: Not specified for any clinical or diagnostic evaluation. The evaluations are primarily non-clinical. For performance testing (ISO 14801), the sample size for individual tests like fatigue is not mentioned within this summary, only that tests were performed.
• Data Provenance: Not applicable in the context of clinical/diagnostic data. For non-clinical tests like biocompatibility and sterilization, previous 510(k) submissions (e.g., K110955, K123988, K210161, K220562, E220672, K230618) from MegaGen Implant Co., Ltd. are leveraged. The tests were performed according to international standards (ISO, ASTM, USP).

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 type of medical device (dental implant abutment) is established by engineering specifications, material properties, and performance under rigorous bench testing conditions, compared to predicate devices. There is no mention of expert consensus for diagnostic ground truth.

4. Adjudication method for the test set

Not applicable. No expert adjudication process for diagnostic imaging or clinical outcomes is 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 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. This device is a physical medical device, not an algorithm.

7. The type of ground truth used

The "ground truth" for demonstrating substantial equivalence is based on:

• Comparison to legally marketed predicate devices (their established safety and effectiveness).
• Compliance with recognized international standards (e.g., ISO 10993-1 for biocompatibility, ISO 11137 for sterilization, ASTM F1980 for shelf-life, ISO 14801 for performance/fatigue testing, and FDA guidance documents for MR compatibility).
• Confirmation through non-clinical bench testing that the device's physical and mechanical properties meet predefined criteria, demonstrating that any differences from predicate devices do not raise new questions of safety or effectiveness.

8. The sample size for the training set

Not applicable. This document describes a physical medical device, not an AI algorithm requiring a training set.

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

Not applicable. This pertains to AI algorithms.

The provided text is a 510(k) Summary for the ALLONUS Tech Prosthetic, which is an endosseous dental implant abutment. It details the device's technical characteristics and compares it to predicate devices to establish substantial equivalence, rather than describing a study that proves the device meets specific acceptance criteria for a new and novel performance claim.

Therefore, many of the requested categories for acceptance criteria and study details are not directly applicable or available in this type of submission. The information provided primarily focuses on demonstrating equivalence through comparison to existing legally marketed devices, material properties, and standard performance tests for similar devices.

However, I can extract the relevant information that is available from the document for each type of device within the ALLONUS Tech Prosthetic family: Pre-Milled Blank, Ti Base, Multi-Unit Abutment, Multi-Unit Healing Cap, Multi-Unit Temporary Cylinder, and Multi-Unit Ti-Cylinder.

General Information on Acceptance Criteria and Studies for ALLONUS Tech Prosthetic (as inferred from the 510(k) Summary):

The ALLONUS Tech Prosthetic is claiming substantial equivalence to predicate devices, meaning it does not need to establish new performance criteria but rather demonstrate that it is as safe and effective as existing legally marketed devices. The "acceptance criteria" here are largely implied by the performance of the predicate devices and the relevant ISO standards for dental implant abutments. The studies performed are non-clinical bench tests.

1. Table of Acceptance Criteria (Inferred from Comparison) and Reported Device Performance:

The document presents comparisons to predicate devices to establish substantial equivalence rather than explicit acceptance criteria and corresponding performance metrics for novel claims. However, the design limits of the subject devices are compared to the design limits of the predicate devices, which act as de facto acceptance criteria in the context of substantial equivalence. The device's performance is demonstrated by meeting the standards in non-clinical testing.

Here's a generalized table summarizing this approach:

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

• Test Set Sample Size:
  • The document does not specify the exact sample sizes used for the non-clinical bench tests (fatigue, sterilization, biocompatibility, or dimensional analysis). It only states that tests were performed "for the subject device" and "of the worst-case scenario through fatigue testing."
• Data Provenance:
  • The 510(k) submission is from ALLONUS Tech Co., LTD. in the REPUBLIC OF KOREA. This implies the testing was likely conducted in or overseen by this entity.
  • The studies were non-clinical bench tests, not clinical studies involving human patients. Therefore, terms like "retrospective" or "prospective" clinical dataProvenance are not applicable here.

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

• This information is not provided in the 510(k) Summary. For non-clinical bench testing, "ground truth" is typically established by recognized international standards (e.g., ISO, ASTM) and engineering principles, rather than expert consensus on clinical cases.
• The document mentions "Dimensional analysis and reverse engineering... were performed" and "assessment of maximum and minimum dimensions... along with cross-sectional images." This suggests engineering expertise, but specific numbers or qualifications of experts are not stated.

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

• This is not applicable as the studies were non-clinical bench tests. Adjudication methods like 2+1 (two readers plus one adjudicator) are used in clinical studies, particularly for diagnostic imaging, to resolve discrepancies in expert interpretations of patient data.

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 type of study (MRMC) is relevant for diagnostic AI devices that assist human interpretation of medical images or data. The ALLONUS Tech Prosthetic is a physical medical device (dental implant abutment), not an AI diagnostic tool.

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

• No, a standalone (algorithm-only) performance study was not done. This question is also typically relevant for AI/software as a medical device (SaMD). The ALLONUS Tech Prosthetic is a physical device that integrates with human dental procedures.

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

• For the non-clinical tests (fatigue, sterilization, biocompatibility), the "ground truth" is adherence to recognized international standards (ISO, ASTM) and established engineering specifications.
• For implant-to-abutment compatibility, the "ground truth" was based on dimensional analysis and reverse engineering of OEM implant bodies, abutments, and screws, comparing the subject device's design to established OEM specifications.

8. The sample size for the training set:

• This is not applicable. "Training set" refers to data used to train machine learning algorithms. The ALLONUS Tech Prosthetic is a physical medical device, not an AI/ML algorithm.

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

• This is not applicable as there is no training set for a physical medical device.

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): Not applicable, as no ground truth for image interpretation or diagnosis is relevant here. The ground truth for mechanical testing is established by engineering standards and measurements.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
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.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Ground truth is based on engineering specifications, material science standards (ASTM, ISO), and validated test methods for physical properties.
8. The sample size for the training set: Not applicable, as there is no AI/ML model for training.
9. How the ground truth for the training set was established: Not applicable.

The provided text describes a 510(k) premarket notification for DESS Dental Smart Solutions, which are dental implant abutments. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving a device's effectiveness through clinical performance studies with specific statistical acceptance criteria for accuracy, sensitivity, or specificity.

Therefore, the document does not contain the information requested regarding:

• A table of acceptance criteria and reported device performance (in terms of clinical metrics like accuracy, sensitivity, specificity).
• Sample size used for the test set or its provenance.
• Number of experts used to establish ground truth or their qualifications.
• Adjudication method for the test set.
• Multi-Reader Multi-Case (MRMC) comparative effectiveness study or its effect size.
• Standalone (algorithm only) performance.
• Type of ground truth used (expert consensus, pathology, outcomes data).
• Sample size for the training set.
• How the ground truth for the training set was established.

The study described in this document focuses on non-clinical performance data to demonstrate substantial equivalence, specifically:

1. Sterilization validation: According to ISO 17665-1, ISO 17665-2, and ISO 14937.
2. Biocompatibility testing: According to ISO 10993-5 and ISO 10993-12.
3. Fatigue testing and reverse engineering analysis: Of OEM implant bodies, OEM abutments, and OEM abutment screws to confirm compatibility. This includes fatigue testing of OEM implant bodies with patient-specific abutments made at worst-case angled conditions.
4. MR Conditional labeling.
5. Validation testing of CAM restriction zones: Including verification to show avoidance of damage or modifications of the connection geometry, and locking of restriction zones from user editing in the CAM software.
6. Software verification: Included testing of restrictions that prevent design of components outside of the stated design parameters. The abutment design library was validated to demonstrate that established design limitations and specifications are locked and cannot be modified by the user.

The acceptance criteria and reported "performance" for this submission are based on these engineering and design validations, ensuring the device meets safety and performance standards equivalent to the predicate device, K221301. The key "performance" metrics are about maintaining physical and material integrity and compatibility.

The core of the submission is to expand the DESS Dental Smart Solutions abutment system to:

• Allow design using AbutmentCAD software (in addition to 3Shape software).
• Add angulation (up to 30°) to some Pre-milled (Blank) Abutments for specific implant systems.

The document explicitly states: "No clinical data were included in this submission." and "The subject device, the predicate device, and reference devices have the same intended use, technological characteristics, and are materials. The subject device, the predicate device, and reference devices encompass the same range of physical dimensions, manufactured by similar methods, are packaged in similar materials, and are to be sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above."

Therefore, this FDA submission is for a physical medical device (dental implant abutment) and its manufacturing/design software modifications, not an AI or diagnostic device that would involve clinical performance metrics like sensitivity or specificity.
