The ISO Abutment is to be placed into the dental implant to provide support for a prosthetic restoration. The ISO Abutment is made from Titanium grade Ti-6AI-4V ELI (meets ASTM Standard F-136) and compatible with several fixtures made by 3rd party implant manufactures.

This 510(k) clearance letter details the regulatory approval for the ISO Abutment, an endosseous dental implant abutment. It establishes its substantial equivalence to a predicate device based on similar indications for use, technological characteristics, materials, design, and sterilization methods.

However, the provided document does not contain information related to software, artificial intelligence (AI), diagnostic accuracy studies, or clinical performance data typically associated with acceptance criteria tables, sample sizes for medical imaging datasets, expert adjudication, or MRMC studies. The device itself is a physical dental implant component, not an AI-powered diagnostic tool.

Therefore, I cannot extract the requested information regarding:

• A table of acceptance criteria and reported device performance (as these would be mechanical and biocompatibility tests, not diagnostic accuracy metrics)
• Sample sizes used for the test set and data provenance (not applicable for this type of device)
• Number of experts used to establish ground truth and qualifications (not applicable)
• Adjudication method (not applicable)
• MRMC comparative effectiveness study (not applicable)
• Standalone (algorithm-only) performance (not applicable)
• Type of ground truth used (e.g., pathology, outcomes data - not applicable for this device beyond engineering/material testing)
• Sample size for the training set (not applicable)
• How the ground truth for the training set was established (not applicable)

The "Non-clinical Tests" section (Page 13) describes the types of studies performed for a physical device, which include:

• Sterilization validation testing (ISO 17665-1 & 2)
• Biocompatibility tests (ISO 10993-5, -10, -11, -3, -33) including:
  • Cytotoxicity
  • Oral mucosa irritation
  • Skin sensitization
  • Acute systemic toxicity
  • Subchronic systemic toxicity
  • Bacterial reverse mutation
• Reverse engineering analysis of OEM implant body, abutment, and fixation screw (for compatibility verification)
• TiN coating tests (F1044, F1147, F1160)
• Non-clinical worst-case MRI review (using scientific evidence and published literature) to assess magnetic induction displacement force (ASTM F2052), magnetic induction torque (ASTM F2213), RF induction heating (ASTM F2182), and image artifact (ASTM F2119).

These tests establish the physical, mechanical, and biological safety and compatibility of the dental abutment, rather than the diagnostic performance of an AI system.

The provided 510(k) summary for DESS Dental Smart Solutions focuses on demonstrating substantial equivalence to predicate devices for dental implant abutments. It primarily addresses the expansion of compatible materials, scanners, CAM software, and milling machines within an existing digital dentistry workflow. The document does not describe an AI/ML-based device that would typically have acceptance criteria related to diagnostic performance.

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.
• Benchmarking/Predicate Equivalence: Performance is assessed against established performance of the predicate devices and OEM implant systems.
• Software Validation Logic: Verification that software correctly enforces design rules and CAD/CAM restrictions.

8. The sample size for the training set

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.

Ask a specific question about this device

IPD Dental Implant Abutments is a dental implant abutment system composed of dental abutments and screws intended to be placed into dental implants to provide support for dental prosthetic restorations. Abutments provide basis for single or multiple tooth prosthetic restorations. They are available in a variety of connection types to enable compatibility with commercially available dental implants systems. IPD Dental Implant Abutments includes the following categories of dental abutment designs: Healing abutments; Temporary abutments; Cementing titanium abutments; Titanium base (interface) abutments; The system also includes the corresponding Titanium Screws intended to attach the prosthesis to the dental implant.

This is a Premarket Notification (510(k)) summary for the IPD Dental Implant Abutments. This document does not describe a study proving the device meets acceptance criteria as would be found in a clinical trial for a novel AI device with specific performance metrics. Instead, it demonstrates substantial equivalence to predicate devices based on bench testing and engineering analysis.

Here's an breakdown of the information provided, tailored to your request, but emphasizing that this is not a typical AI/ML performance study:

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a 510(k) for dental abutments, the "acceptance criteria" are not reported as specific performance metrics (like sensitivity/specificity for an AI model), but rather as compliance with recognized standards and demonstration of substantial equivalence to predicate devices. The "reported device performance" refers to successful completion of various non-clinical tests.

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

• Sample Size for Test Set: Not applicable in the context of human data or AI model test sets. The "test set" here refers to the physical samples of the IPD Dental Implant Abutments (and their components, potentially in various configurations) that were subjected to the specified bench and biocompatibility tests. The exact number of physical abutments, screws, or zirconia superstructures tested for each specific criterion is not detailed in this summary but would be found in the full test reports.
• Data Provenance: Not applicable in the context of country of origin for patient data. The tests were performed on the manufactured device components. The materials are specified (e.g., Titanium alloy conforming to ISO 5832-3).

3. 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 would generally refer to expert-derived labels for clinical data, which is not part of this 510(k) submission. The "truth" for the performance tests is established by adherence to recognized international standards (e.g., ISO, FDA Guidance) and objective measurements from engineering or biological tests.

4. Adjudication method for the test set

Not applicable. Adjudication methods (like 2+1 or 3+1) are used for resolving disagreements among human readers or expert labelers of clinical data, which is not relevant here. The evaluation criteria for the bench tests are objective and defined by established 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 device is a dental implant abutment, not an AI software. Therefore, MRMC studies and AI assistance effect sizes are not relevant to this submission.

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

No. This is a physical medical device (dental abutments), not a standalone algorithm.

7. The type of ground truth used

The "ground truth" for this device's performance is established by:

• Compliance with international standards (e.g., ISO 14801 for fatigue testing, ISO 10993 series for biocompatibility, ISO 17665-1 for sterilization).
• Engineering specifications and dimensional analysis to ensure compatibility with other specified dental implant systems.
• Validated digital dentistry workflow parameters (e.g., minimum gingival height, wall thickness, post height, angulation for zirconia superstructures), which are based on established dental prosthetic principles.

8. The sample size for the 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

Not applicable. No training set is used for this physical device.

DESS Dental Smart Solutions abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for prosthetic restorations.

All digitally designed custom abutments for use with DESS Ti Base abutments or Pre-Milled Blank abutments are to be sent to a Terrats Medical validated milling center for manufacture.

The purpose of this submission is to add components to the DESS Dental Smart Solutions system, which includes dental implants, abutments, and prosthetic components cleared previously in various submissions. The previously cleared abutments and prosthetic components are compatible with a variety of original equipment manufacturer (OEM) dental implants as well as DESS Dental Smart Solutions dental implants.

This submission adds various abutments to the DESS and OEM implant lines as summarized on the following pages in Table 1 Summary of Subject Device Abutment Designs, and Table 2 Summary of Subject Device Abutment Sizes.

The subject device abutment designs include Cover Screws, Healing Abutments, Temporary Abutments, Ti Base Abutments, AURUM Base Abutments (Ti Base abutments with a screw channel design that allows easier instrument access to the abutment screw), CoCr Base Abutments, Pre-Milled Blank Abutments, Multi-Unit Abutments (straight and angled), DESSLoc Abutments (Locator-type abutments), and abutment screws.

This document is a 510(k) summary for the DESS Dental Smart Solutions, a line of endosseous dental implant abutments. It details the device's characteristics, intended use, and a comparison to predicate devices to establish substantial equivalence.

Based on the provided text, the device itself is a physical medical device (dental implant abutments and associated components), not a software or AI-driven system. Therefore, the questions related to AI acceptance criteria, training/test sets, expert adjudication, MRMC studies, and ground truth establishment for AI would not be directly applicable to this product as described.

The document focuses on establishing substantial equivalence to previously cleared predicate devices through:

• Identical Intended Use: The device is intended for "functional and esthetic rehabilitation of the edentulous mandible or maxilla" by providing support for prosthetic restorations, which is the same as the predicate devices.
• Similar Technological Characteristics: The device utilizes similar designs, materials (Ti-6Al-4V, Co-Cr-Mo alloy), manufacturing processes, and sterilization methods as its predicates.
• Performance Data: Non-clinical testing (mechanical testing per ISO 14801, MR environment assessment) and comparison to existing data from predicate devices are used to demonstrate safety and effectiveness.

Therefore, many of the requested elements for describing AI acceptance criteria and studies are not present or applicable in this document.

However, I can extract information relevant to the device's performance assessment and criteria for its type of submission.

Here's an attempt to answer the questions based solely on the provided text, acknowledging that the nature of the device (a physical implant component) means many AI-specific questions will be answered as "Not Applicable" (N/A):

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

The document does not explicitly state quantifiable "acceptance criteria" in a table format with corresponding "reported device performance" metrics for this specific 510(k) submission. Instead, it relies on demonstrating substantial equivalence to existing predicate devices.

The underlying "acceptance criteria" for demonstrating substantial equivalence for this device type are primarily through:

• Mechanical Testing (ISO 14801): This is a critical performance standard for dental implants and abutments. The document states that mechanical testing was "conducted according to ISO 14801 to support the performance." The acceptance criteria would be successful completion of these tests, demonstrating the device's mechanical strength and fatigue resistance are comparable to or better than predicate devices. The reported performance is simply that the tests supported the performance.
• Material Conformance: Materials must conform to specific ASTM standards (e.g., ASTM F136 for Ti-6Al-4V, ASTM F1537 for Co-Cr-Mo). The reported performance is that the materials conform to these standards.
• Biocompatibility: While not detailed in this excerpt, the mention of "biocompatibility" in relation to predicates implies conformance to relevant biocompatibility standards (e.g., ISO 10993 series). The reported performance is that it is compatible.
• Sterilization Validation: Demonstrated sterility assurance level (SAL) of 10⁻⁶ via validated methods (moist heat or gamma irradiation). The reported performance is that validation was performed and met this SAL.
• Dimensional Compatibility: The abutments must fit the corresponding OEM implants correctly. The reported performance is that reverse engineering dimensional analysis confirmed compatibility.

Due to the nature of the document being a 510(k) summary focusing on substantial equivalence rather than a full study report, specific numerical performance results for the device tests are not provided in this text.

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

• Sample Size for Mechanical Testing: The document states "mechanical testing conducted according to ISO 14801." For such tests, ISO 14801 typically specifies minimum sample sizes (e.g., 10-11 samples for static strength, typically more for fatigue). The exact number of samples used for this specific submission is not explicitly stated, but it would have followed the standard's requirements.
• Data Provenance: The mechanical testing and material analyses are assumed to be "non-clinical data submitted or referenced" by the manufacturer, Terrats Medical SL, based in Barcelona, Spain. The "reverse engineering dimensional analysis" was done by Terrats Medical SL or through contractual agreement. This is prospective testing performed to support the 510(k). The document itself does not specify the country of origin for the underlying OEM implant data used for reverse engineering, although the OEM companies are listed (e.g., Astra Tech AB, BioHorizons).

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

N/A. This is a physical device. Ground truth, in the context of AI, refers to validated labels for data used to train and test an algorithm. For a physical device, performance is evaluated through engineering and biocompatibility testing against defined standards. There are no "experts" establishing ground truth in the AI sense. Testing would be performed by qualified engineers and technicians.

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

N/A. Adjudication methods are typically used in clinical studies involving interpretation (e.g., by radiologists) to resolve discrepancies. This document describes non-clinical performance testing of a physical device.

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

N/A. This product is a dental implant abutment, not an AI software intended to assist human readers.

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

N/A. This is a physical device, not an algorithm.

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

N/A. For engineering tests of physical devices, the "ground truth" is typically derived from established engineering principles, international standards (e.g., ISO 14801 for mechanical properties, ASTM for materials), and the physical properties of the materials and designs themselves. There isn't "expert consensus" or "pathology" in the AI or clinical trials sense.

8. The sample size for the training set

N/A. This is a physical device; there's no "training set" in the machine learning sense. The device is manufactured based on established engineering designs and material specifications.

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

N/A. No training set for AI. For device manufacturing, the "ground truth" for design and production parameters comes from established engineering best practices, prior successful device designs (predicate devices), and adherence to quality systems regulations (21 CFR Part 820).

The patient-specific abutment milled from a Pre-milled Abutment Blank is secured directly to the implant using a retaining screw. Pre-milled Abutment Blanks are available in an engaging/hexed design only for single-unit and multi-unit restorations.

Retaining Screws: Corresponding retaining screws are packaged with the abutment and replacement screws are available individually. All screws are compatible with the corresponding ZimVie dental implants.

Material Composition: All subject device abutments are made of titanium alloy Ti-6Al-4V ELI conforming to ASTM F136. Screws are made of either titanium alloy Ti-6A1-4V ELI conforming to ASTM F136, or Gold-Tite® screws with stainless steel conforming to ASTM F138. Gold-Tite screws have a gold-plating conforming to ASTM B488 and ASTM B571. Zirconia superstructures for use with the TiBase Abutments are made of zirconia conforming to ISO 13356.

The provided text is an FDA 510(k) clearance letter for Zfx Abutments, and as such, it focuses on demonstrating substantial equivalence to a predicate device rather than presenting a performance study with detailed acceptance criteria and supporting data in the way a clinical study report or a formal performance evaluation report would.

Therefore, the information required to answer many of the questions regarding acceptance criteria, sample sizes, expert involvement, and ground truth establishment is not present in this document. The document primarily outlines the device's technical specifications, indications for use, and a comparison to predicate devices, supported by non-clinical testing data (mechanical testing, biocompatibility, sterilization, etc.).

However, I can extract the information that is available and explain why other requested details are missing.

Acceptance Criteria and Device Performance (Based on "Equivalence to Marketed Devices" and "Performance Data" sections):

This document describes a substantial equivalence submission, meaning the acceptance criteria are primarily demonstrated by showing the device is as safe and effective as a legally marketed predicate device. The performance is assessed through non-clinical testing to ensure it meets established standards comparable to the predicate.

Missing Information and Explanations:

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

   • Not provided. This document details a 510(k) submission based on non-clinical testing for substantial equivalence, not a clinical trial or performance study with human data. The "Performance Data" section explicitly states: "No clinical data were included in this submission." Therefore, there is no "test set" in the context of clinical images or patient data to analyze. The "samples" used were physical samples for mechanical, sterilization, and biocompatibility testing. The data provenance would be from laboratory tests.

2. 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/Not provided. As no clinical data or clinical "test set" was used, there was no need for expert adjudication to establish ground truth from patient data. The ground truth for mechanical and material properties is established by engineering specifications and industry standards.

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

   • Not applicable/None. No clinical test set to adjudicate.

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:

   • Not applicable. This device (Zfx Abutments) is a physical dental implant component, not an AI software/device. Therefore, an MRMC study or AI assistance is not relevant to its performance evaluation for this submission.

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

   • Not applicable. As above, this is a physical medical device, not an algorithm or AI.

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

   • The "ground truth" for demonstrating substantial equivalence for this device relies on engineering specifications, material standards (e.g., ASTM, ISO), mechanical test results (e.g., forces to fracture), and comparative analysis with the predicate device's established safe and effective performance. There is no clinical outcomes ground truth cited here.

7. The sample size for the training set:

   • Not applicable. This refers to a dataset for training an AI model. This device is not an AI/software.

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

   • Not applicable. As above, no training set for an AI model.

In summary, this document is a regulatory clearance letter focused on substantial equivalence for a physical dental device. The "study" proving it meets acceptance criteria consists of various non-clinical bench tests and a comparison to a predicate device's specifications and performance, rather than a clinical study with patients or an AI model's performance evaluation.

DESS Dental Smart Solutions abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandibular arch to provide support for prosthetic restorations.

The purpose of this submission is to expand the DESS Dental Smart Solutions abutment system by a change in sterilization status to provide products sterile to the end user that were previously cleared to be provided non-sterile. The subject device abutments and abutment screws were cleared previously to be provided non-sterile to the end user in K170588, K191986, K212628, and K22288. All subject device components will now be provided sterile.

The subject device components include Healing Abutments, Multi-Unit Abutments (0, 17°, and 30°), and abutment screws.

The provided text is a 510(k) summary for the DESS Dental Smart Solutions, an endosseous dental implant abutment. It details the device, its intended use, and its substantial equivalence to previously cleared predicate and reference devices. However, this document does not contain the acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML medical device.

The 510(k) submission for this dental abutment focuses on establishing substantial equivalence based on:

• Design and Material: The subject device components are identical in design, material (Ti-6Al-4V alloy, DLC coating), and technological characteristics to previously cleared devices.
• Manufacturing: The manufacturing process is consistent with previously cleared devices.
• Biocompatibility: Referenced from previous K-clearances.
• Sterilization: The main change in this submission is expanding the system to provide products sterile to the end-user via gamma irradiation, which was validated by referencing a previous K-clearance (K212538).
• MR Environment Testing: Non-clinical analysis was performed to evaluate the subject devices in the MR environment, referencing published literature and FDA guidance.
• Shelf Life Testing: Referenced from a previous K-clearance (K212538) for samples after accelerated aging.

Therefore, I cannot fulfill your request to describe the acceptance criteria and a study proving an AI/ML device meets them based on the provided text, as this document is not about an AI/ML medical device. It's about dental implant abutments and establishes substantial equivalence through non-clinical performance data and comparison to predicate devices, not through AI/ML performance metrics.

To provide the information you requested, I would need a document detailing the validation of an AI/ML medical device, which would include definitions of acceptance criteria (e.g., accuracy, sensitivity, specificity), details of training and test datasets, ground truth establishment, and potentially clinical effectiveness studies if applicable.

Multi-Unit DAS System abutments are intended for use with dental implants as a support for single-unit or multi-unit prostheses in the maxillary or mandibular arch of a partially or fully edentulous patient.

Multi-Unit DAS System abutments are designed for retention of single-unit and multi-unit restorations. The multi-unit abutments are provided in a straight design (no angulation in the base portion) that threads directly to the OEM implant. For each of the compatible OEM implant lines, the multi-unit abutments are provided with gingival heights ranging from 1 mm to 5 mm, a prosthetic platform diameter of 4 mm, and a prosthetic post height of 1.4 mm. The multi-unit abutments are the base of a two-piece abutment. The second piece is a metal coping, called a Ti-Base in this submission, that attaches to the multi-unit abutment (not directly to an implant). For permanent restorations a zirconia superstructure is attached to the Ti-Base, and additional gingival height and angulation may be provided in the zirconia superstructure.

The subject device metal copings (Ti-Bases) include: a straight, prepable design with an additional gingival height of 1.5 mm and a prepable 9 mm prosthetic post; and Dynamic Ti-Bases in three (3) designs, each with an additional gingival height of 0.5 mm and a cut-out in the prosthetic post to accommodate a restoration with an angled screw channel when clinically necessary. The Dynamic Ti-Base prosthetic post heights are 4.5 mm (maximum height) / 3.0 mm (cut-out height), and 9.0 mm/3.5 mm. Multi-Unit DAS System Ti-Bases with a 9.0 mm post height may be shortened to no less than 4 mm for a single-unit restoration. The prepable Ti-Base has a platform diameter of 4 mm (platform to the multi-unit abutment) and a prosthetic platform diameter of 4 mm. The Dynamic Ti-Bases have a platform diameter of 4 mm (platform to the multi-unit abutment) and a prosthetic platform diameter of 4.15 mm.

The compatibility between the subject device abutments and the OEM implants listed in the Indication for Use Statement was established by reverse engineering analysis of the OEM implants, OEM abutments, and OEM abutment screws.

All subject device abutments and abutment screws are made of titanium alloy (Ti-6Al-4V) conforming to ASTM F136 and ISO 5832-3.

All zirconia copings (superstructures) for use with the subject device Dynamic Ti-Base will be made at a Talladium España, SL validated milling center under FDA quality system regulations, and the material will conform to ISO 13356.

The design parameters for the CAD-CAM zirconia superstructure for the Multi-Unit DAS System are:

Minimum wall thickness - 0.25 mm

Minimum post height for single-unit restorations - 4.0 mm

Maximum gingival height in the zirconia superstructure - 5.24 mm for compatible Biomet 31 OSSEOTITE® Certain®, MegaGen AnyRidge, NobelActive®, and Zimmer Tapered Screw-Vent® implants; 5.76 mm for compatible Astra Tech OsseoSpeed TX implants

Minimum gingival height - 0.5 mm (in the Ti-Base)

Maximum angulation - 30° for compatible Biomet 3i OSSEOTITE® Certain®, MegaGen AnyRidge, NobelActive®, and Zimmer Tapered Screw-Vent® implants; 25° for compatible Astra Tech OsseoSpeed TX implants

The recommended cement for bonding the zirconia superstructure to the Dynamic TiBases to create the final two-piece abutment is G-CEM LinkAce™, cleared as GAM-200 in K120243.

Dynamic TiBase abutments are intended for use with dental implants as a support for single-unit or multi-unit prostheses in the maxillary or mandibular arch of a partially or fully edentulous patient.

Dynamic TiBase abutments are designed for retention of a CAD-CAM fabricated zirconia superstructure where the final two-piece abutment (base and cemented superstructure) is the finished device used for the prosthetic restoration. Dynamic TiBase abutments are provided in engaging and non-engaging designs for single-unit and multi-unit restorations, respectively. For each of the compatible OEM implant lines, the Dynamic TiBase abutments are provided with a gingival height (in the titanium base) ranging from 0.3 mm to 5 mm, and a prosthetic platform diameter ranging from 4.3 mm to 5.9 mm. Additional gingival height and angulation may be provided in the zirconia superstructure. All Dynamic TiBase abutments have a prosthetic post with a cut-out to accommodate a restoration with an angled channel for screw access when clinically necessary. The prosthetic post heights range from 3.8 mm to 4.5 mm (maximum height), and from 2.3 mm to 2.7 mm (cut-out height). Dynamic TiBase abutments with a 4.5 mm maximum post height may be shortened to no less than 4 mm for a single-unit restoration. All subject device abutments and abutment screws are made of titanium alloy (Ti-6A1-4V) conforming to ASTM F136 and ISO 5832-3. All zirconia copings (superstructures) for use with the subject device Dynamic TiBase will be made at a Talladium España, SL validated milling center under FDA quality system regulations, and the material will conform to ISO 13356.
