The subject device abutments platform diameters range from 3.5mm to 6.3mm, and the corresponding compatible implant body diameters also range from 3.5 mm to 6.3mm. The system also includes corresponding abutment screws.

Temporary Abutments are manufactured from Titanium Grade 5 and consist of a coronal section, a platform and a connection part. The abutments are provided non-sterile with instructions for end user sterilization. The Temporary Abutments are seated in the implant with a prosthetic screw which is also manufactured from Titanium Grade 5. The prosthetic screw is delivered with the abutment. Angular correction of temporary abutments and placement of implant bodies at an angle is not allowed, they must be used parallel to the direction of occlusal loading forces. Temporary Abutments can be used prior to the insertion of the final components to maintain, stabilize and shape the soft tissue during the healing phase; they may not be placed into occlusion. Modifications can be made by the end-user only in the minimum post height. Minimum post height – 4.0 mm. Temporary Abutments have a maximum duration of usage of 180 days.

The Bonafix TiBase abutment is composed of two-piece abutment that is a titanium base at the bottom and a zirconia superstructure (CAD/CAM patient specific superstructure) at the top. The superstructure are fabricated using a CAD/CAM process in Zirconia. The apical end is prefabricated to fit the compatible implant platform, as shown above, and is available with implant connections for crowns (with socket) or bridges (without socket). Angular correction of abutments and placement of implant bodies at an angle is not allowed, they must be used parallel to the direction of occlusal loading forces. Each abutment is provided with a screw designed to fit the compatible implant. The design parameters for the fabrication of the zirconia superstructure, which are already locked in the CAD/CAM software, are as follows: Minimum wall thickness – 0.45 mm, Minimum abutment post height – 4.0 mm, Maximum abutment post height – 6.5mm, Maximum gingival height – 5.0 mm, Minimum gingival height – 0.7 mm, Angulation – 0°.

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.

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.

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).

This looks like a 510(k) Summary for a medical device (dental abutments), which means the document is about proving "substantial equivalence" to a predicate device, not about proving clinical effectiveness or performance against pre-defined acceptance criteria in the way one might for a novel AI/software medical device.

Therefore, the information requested in your bullet points (e.g., acceptance criteria table, sample size for test set, number of experts for ground truth, MRMC study, standalone performance, training set details) is not applicable to this type of regulatory submission because the device is a mechanical one, not an AI/software device. The data presented here is focused on demonstrating physical and mechanical compatibility and equivalence to previously cleared devices.

Here's why each point is not applicable and what information is provided:

1. A table of acceptance criteria and the reported device performance: This document doesn't provide a typical "acceptance criteria" table as would be seen for an AI/software device measuring diagnostic performance (e.g., sensitivity, specificity, AUC). Instead, it relies on demonstrating that the new abutments perform similarly to existing, cleared abutments through "dynamic fatigue testing" and "dimensional analysis and reverse engineering." The performance is implicitly "accepted" if these tests show equivalence to the predicate.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): No "test set" in the context of diagnostic performance is mentioned. The "testing" refers to non-clinical, physical testing (fatigue, dimensional analysis). There is no patient data involved in this type of submission for a mechanical 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. Ground truth, in the AI/software sense, is not established for this device. The "truth" is based on engineered specifications and physical testing.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No human adjudication of diagnostic output is relevant here.

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 is not an AI-assisted device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable. The "ground truth" is engineering specifications and physical measurements.

8. The sample size for the training set: Not applicable. There is no AI/machine learning component to "train."

9. How the ground truth for the training set was established: Not applicable for the same reason as above.

What the document does provide regarding device performance and testing:

• Type of Testing:

  • Dynamic fatigue testing according to FDA guidance and ISO 14801 (Dentistry - implants dynamic loading test for endosseous dental implants).
  • Dimensional analysis and reverse engineering of the implant-to-abutment connection platform.
  • Sterilization validation (steam and gamma irradiation) referenced from K191123, ISO 17665-1, ISO/TS 17665-2, ISO 11137-1, ISO 11137-2.
  • Sterile packaging validation referenced from K191123, ISO 11607-1, ISO 11607-2.
  • Biocompatibility evaluations referenced from K142167, K170838, K191123, K150203, K061804 in accordance with ISO 10993-1.
  • MR testing referenced from K180564 in accordance with ASTM F2052-15, ASTM F2213-06 (2011), ASTM F2182-11a, and ASTM F2119-13.

• Conclusion: The tests demonstrated "implant to abutment compatibility" and "established substantial equivalency of the proposed device with predicate devices." This is the "proof" that the device meets the (implicit) acceptance of being substantially equivalent to existing, legally marketed devices.

In summary, this document is for a traditional mechanical medical device, and the regulatory pathway does not involve performance studies in the way you've outlined for AI/software-based devices.

Ask a specific question about this 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.

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.

Here's a breakdown of the acceptance criteria and study information for the Multi-Unit DAS System:

1. Table of Acceptance Criteria and Reported Device Performance

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

• Mechanical Testing (ISO 14801) & Sterilization Validation: The document does not explicitly state the sample sizes used for these tests. For ISO 14801, typically a statistically significant number of samples are tested to demonstrate fatigue resistance, but the exact number isn't provided. For sterilization, typically multiple runs with biological indicators are performed.
• Data Provenance: The document does not specify the country of origin for the data for specific tests, but the manufacturer, Talladium España, SL, is located in Lleida, Spain. The data is non-clinical.

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 (N/A) as the submission details non-clinical data (mechanical testing, material specifications, biocompatibility, sterilization, MR safety analysis) rather than studies involving human expert assessment of images or clinical outcomes.
