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 Straumann Custom Abutments are indicated for single tooth replacement and multiple tooth restorations. The prosthetic restoration can be cemented.
The Straumann Custom Abutments (previously named Straumann CARES Abutments) are used for the restoration of Straumann dental implants of different types, endosteal diameters, lengths and platforms. The Custom Abutments are patient-matched abutments; the customer scans the intraoral situation and designs the shape using a Straumann-approved CAD/CAM software (such as Straumann CARES Visual). The design data is then transferred to Straumann where the fabrication of the custom abutment is carried out at a Straumann validated milling center (FEI: 3024185724 or FEI: 3011221537). The existing Custom Abutments feature a straight screw channel for the basal screw which fixes the abutment to the respective implant. The purpose of this submission is to add Custom Abutments with an angled screw channel to the Straumann Custom Abutment Portfolio. The subject Custom Abutments can be designed and manufactured with an angled screw channel (as opposed to straight), so that the screwexit is located in a favorable position (away from the incisal/occlusal edge and tooth cusps) for esthetic and functional results. The screw channel can be angled, the screwdriver maximum angle is 20°.
The Custom Abutments are designed for connection to implants of the Straumann Dental Implant System. The Custom Abutments have an implant-specific connection interface for the respective compatible implant. The Custom Abutments with the SynOcta geometry (RN or WN) are designed for connection to the Straumann Tissue Level (TL) implants. Those with the CrossFit geometry (NC or RC) are designed for connection to the Bone Level (BL) and Bone Level Tapered (BLT) implants. The Custom Abutments with the TorcFit geometry, are designed for connection to the Straumann Bone Level BLX and BLC (RB/WB or WB) or Tissue Level TLX and TLC (NT, RT, WT) implants. The basal screws feature threads to secure the abutment with the implant inner geometry. The basal screws also contain the connection geometry to mate with the AS screwdrivers for installation into the implant.
The provided text is a 510(k) Summary for "Custom Abutments" and details the substantial equivalence of the device to legally marketed predicate devices. It does not contain information on an AI/ML-driven device or study results proving a device meets acceptance criteria related to AI/ML performance metrics (e.g., sensitivity, specificity, FROC, etc.).
The document describes a dental implant abutment designed for customized patient use, with a key modification being the addition of an angled screw channel. The non-clinical testing sections focus on mechanical fatigue testing, digital workflow validation, sterilization, MRI compatibility, and biocompatibility, as is typical for a medical device of this type.
Therefore, I cannot fulfill your request for information on acceptance criteria and study proving device meets acceptance criteria for an AI/ML device, as the provided text pertains to a traditional medical device (dental abutments) and does not mention any AI/ML component.

The subject abutments also include abutments compatible with new implant diameters in existing Medentika series (E, EV, F, and S). Lastly, the subject abutments include new abutment designs compatible with existing implant diameters in existing Medentika series (R).
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:
-
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.
-
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.
-
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.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No human adjudication of diagnostic output is relevant here.
-
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.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an algorithm.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable. The "ground truth" is engineering specifications and physical measurements.
-
The sample size for the training set: Not applicable. There is no AI/machine learning component to "train."
-
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.

Kontact™ Dental Implant System 3 mm diameter implants and prosthetics components are indicated for use in surgical and restorative applications in the maxillary lateral incisor or mandibular incisor regions.
All digitally designed Kontact™ Dental Implant System CAD/CAM abutments are intended to be sent to a Biotech Dental validated milling center for manufacture.
The purpose of this submission is to expand the marketing clearance for Kontact™ Dental Implant System which comprises endosseous root-form dental implants and prosthetic components for single-unit, multi-unit, and overdenture restorations to include two additional implant body designs, new Narrow Conical and Conical abutments, hand-milled FitPost abutments, inserts for the previously cleared UniPost abutments and CAD/CAM Titanium base and Titanium Blank, dental implant abutments.
The Kontact™ Dental Implant System Subject device include two implant designs: Kontact S+. The Kontact S and compatible Kontact implants are provided in five body diameters: 3.0 mm, 4.2 mm, 4.8 mm, and 5.4 mm. The body diameter for each implant is equal to the implant platform diameter. The 3.0 mm body implants have a smaller diameter and unique restorative interface. The 3.6 mm, 4.8 mm, and 5.4 mm implants share the same restorative interface. The Kontact S implants are provided in lengths ranging from 8 mm to 16 mm.
The Kontact S+ implants are provided in four body diameters: 4.0 mm, 4.5 mm, 5.0 mm, and 5.5 mm. The 4.0 mm body diameter implants have an implant platform diameter of 3.6 mm and 5.5 mm body diameter implants have an implant platform diameter of 4.2 mm diameter implants are available in both 3.6 mm and 4.2 mm implant platform diameters. All Kontact S+ implants share restorative interface as the 3.6 mm and larger diameter Kontact S implants. The Kontact S+ implants are provided in lengths ranging from 8 mm to 12 mm.
The implants have a recessed internal section for abutment indexing, and an internal threaded section for mating to the corresponding subject device cover screw, or abutment screw.

The endosseous threaded surface of the Kontact S+ implants are gritblasted with resorbable beta-tricalcium phosphate (β-ΤCP) particles.
Grit-blasting of the Kontact S+ implants create a roughened surface which provides an increase in total contact area of the implant surface to facilitate osseointegration.
The Subject device prosthetic components include seven implant abutment designs: Straight Conical, 30° Angulated Conical (indexed and non-indexed), Titanium Base, Titanium Blank and FitPost. The abutments designs are compatible with the Kontact, Kontact S+ implants. All Subject device abutments are manufactured titanium alloy conforming to ASTM F136 and ISO 5832-3.
The provided document describes the K213997 Kontact Dental Implant System. This premarket notification primarily focuses on demonstrating substantial equivalence to a predicate device through non-clinical performance testing and literature review, rather than establishing performance criteria against specific clinical endpoints with a device that provides diagnostic information. Therefore, the typical structure for acceptance criteria and a study proving a device meets these criteria for an AI/ML diagnostic or prognostic device is not directly applicable.
However, I can extract the relevant information from the document to describe how the manufacturer demonstrated that their device met the safety and performance requirements for a dental implant system.
Here's the information organized based on your request, with adaptations for a non-diagnostic medical device:
1. Table of Acceptance Criteria and Reported Device Performance
For this type of device (dental implant system), "acceptance criteria" are generally derived from recognized standards for biocompatibility and mechanical performance, and "reported device performance" refers to the results of non-clinical testing against these standards, as well as a review of clinical outcomes from a published study on similar implants.
Acceptance Criteria (Relevant Standards/Benchmarks) | Reported Device Performance |
---|---|
Biocompatibility: In accordance with ISO 10993-1, including Cytotoxicity (ISO 10993-5:2009) and Endotoxins (ANSI/AAMI ST72:2019). | Cytotoxicity: Performed and results were satisfactory. |
Endotoxins: Performed and results were satisfactory. | |
Overall Biocompatibility: Evaluated through published literature, internal routine monitoring data, and post-market surveillance data on implants made from the same material and surface treatment, indicating "failure rates below industry levels." | |
Mechanical Performance: Static compression and compression fatigue testing according to ISO 14801 (worst-case constructs). | ISO 14801 Testing: Performed on worst-case constructs of the Subject device (covering implant platform, gingival height, and post correction angles combinations). Results demonstrated suitability for intended use, mitigating minor differences in designs, dimensions, or sizes compared to predicate/reference devices. |
Sterilization: Steam Sterilization according to ISO 17665-1 and ISO TS 17665-2. | Steam Sterilization: Protocols leveraged from the prior K210220 Primary Predicate device clearance, indicating compliance. |
MRI Safety Assessment: Parameters per FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" (magnetically induced displacement force and torque). | MRI Safety Assessment: Non-clinical worst-case MRI review performed using scientific rationale and published literature (e.g., Woods et al., 2019). The rationale addressed parameters for the entire system (all compatible implant bodies, abutments, and fixation screws) and material composition, demonstrating adequate safety in the MR environment. |
Clinical Performance (Indirect): Acceptable bone-level changes and implant survival rates in a clinical context (benchmarked against industry standards). | Published Retrospective Study: Evaluated bone levels of 326 implants, showing decreases less than 1 mm ("well within accepted levels") through 50 months post-implantation, with an overall implant survival rate of 98% at 1 year. (This study was not performed by the submitter for this clearance but was leveraged as part of the biological evaluation and demonstration of clinical performance of similar implants). |
2. Sample Size Used for the Test Set and Data Provenance
For the non-clinical tests:
- Biocompatibility: The specific sample sizes for cytotoxicity and endotoxin tests are not individually stated but are implied to be sufficient per the referenced ISO and ANSI/AAMI standards.
- Mechanical Performance (ISO 14801): The sample size refers to "worst-case constructs," implying a selection of implant and abutment combinations designed to represent the most challenging scenarios for mechanical failure. The exact number is not explicitly stated.
- Data Provenance: The mechanical performance and sterilization data are from non-clinical bench testing conducted by the manufacturer. The biocompatibility evaluation also involved internal routine monitoring data.
For the leveraged clinical performance:
- Sample Size: 326 implants were evaluated in a published multi-center retrospective study.
- Data Provenance: This was a retrospective study. The country of origin is not specified, but it was a "multi-center" study.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts
This information is not directly applicable as this submission is not for an AI/ML diagnostic device requiring expert-established ground truth for a test set. The "ground truth" for this dental implant system is primarily established by:
- Compliance with recognized international standards (ISO, ANSI/AAMI): These standards define acceptable material properties and mechanical performance.
- Observation of physical outcomes in non-clinical bench tests: Mechanical integrity, sterilization efficacy, and MRI compatibility are directly measured.
- Leveraged Clinical Literature: The multi-center retrospective study (not conducted by the submitter) provides clinical outcome data (bone level changes, survival rate) for similar implants. The experts involved in that study (e.g., dentists, surgeons, researchers) would have established the "ground truth" of patient outcomes, though no specific number or qualifications are provided in this submission for that study.
4. Adjudication Method for the Test Set
Not applicable in the context of an AI/ML diagnostic or prognostic device with human adjudication. The "adjudication" for this device involves applying the results of the non-clinical tests (e.g., pass/fail for mechanical loads, conformity to biocompatibility limits) against the requirements of the referenced standards.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This is a dental implant system, not a diagnostic imaging device with AI assistance for human readers.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical medical device (dental implant system), not an algorithm.
7. The Type of Ground Truth Used
- Non-clinical Testing: The ground truth for mechanical performance, sterility, and MRI safety is established by direct measurement and observation against predefined criteria in recognized scientific and engineering standards (e.g., force limits, microbial kill rates, magnetic susceptibility properties).
- Biocompatibility: Established by adherence to ISO 10993 standards for various biological endpoints, alongside review of existing data.
- Clinical Outcomes Data (leveraged): For the indirect clinical performance evaluation, the ground truth was based on clinical outcomes (bone-level changes, implant survival rates) derived from a published multi-center retrospective study.
8. The Sample Size for the Training Set
Not applicable. This device is not an AI/ML algorithm that requires a training set. The design and manufacturing processes are informed by engineering principles, material science, and prior predicate device data, rather than machine learning on a "training set."
9. How the Ground Truth for the Training Set was Established
Not applicable, as there is no training set for this type of device.

The CARES® Screw Retain Bars and Bridges, referenced in Table 1, are used for the restoration of different dental implants systems with different endosteal diameters, lengths and platforms. The bars and bridges presented in the premarket notification submission (identified as "SRBB" for Screw Retained Bridges and Bars) are designed to interface with different implant connections. They allow for individual customization regarding function and esthetics. They attach directly to dental implants. The devices are intended to be finished into a bridge or overdenture using standard dental laboratory techniques and materials. Screw Retained Bars and Bridges (SRBB) devices facilitate customization to meet the functional and esthetic requirements of the individual patient. They are patient-specific medical devices, i.e. they are designed by a dental professional (clinician or dental technician) and fabricated by Medentika specifically for an individual patient. SRBB devices are designed via Computer Aided Design (CAD). After importing a scan of the patient model, Commercial Off-The-Shelf (COTS) Software includes the ability to generate digital restoration models incorporating the subject devices. The digital restoration model is transferred to the milling center where the restoration is produced using Computer Aided Manufacturing (CAM)-techniques. The devices are made entirely of titanium Grade 5 according to ASTM F136, Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications.
The document provided is a 510(k) summary for a medical device (CARES® Screw - Retained Bars and Bridges) and does not contain information about the acceptance criteria and study proving a device meets them. This type of document is a premarket notification to the FDA to demonstrate substantial equivalence to legally marketed predicate devices, not a report of comprehensive performance testing with specific acceptance criteria and detailed study results.
The document discusses performance testing in a general sense, stating that dynamic fatigue testing was conducted according to FDA guidance and demonstrated equivalence to predicate and reference devices. However, it does not provide specific numerical acceptance criteria or the reported device performance against those criteria.
The following information from your request cannot be provided based on the given document:
- A table of acceptance criteria and the reported device performance
- Sample sizes used for the test set and data provenance
- Number of experts used to establish the ground truth and their qualifications
- Adjudication method
- Multi-reader multi-case (MRMC) comparative effectiveness study results
- Standalone (algorithm-only) performance results
- Type of ground truth used
- Sample size for the training set
- How the ground truth for the training set was established
The document mentions that dynamic fatigue testing was performed according to FDA guidance and that "Reverse Engineering Analysis" was conducted for certain implant compatibilities. For the GM-Series, implant connections were shared through a business partnership. The change in design workflow did not require additional testing as design parameters are identical and respected by trained technicians.
In summary, the provided text confirms that performance testing was conducted, but it does not detail the acceptance criteria or specific results, nor does it describe a study in the format typically required for your request.

Straumann® CARES® Screw-retained Bridges and Bars are indicated for use as bars and bridges that attach to implants to provide support for prosthetic reconstructions such as bridges and overdentures. The final processed products have the purpose of restoring chewing function. Straumann® CARES® Screw-retained Bridges and Bars are indicated for screw-retained restorations. Straumann® CARES® Screw-retained Bridges and Bars are designed to interface with the Bone Level (BL), Tissue Level (TL), and BLX implants of the Straumann Dental Implant System (SDIS).
The Straumann® CARES Screw-Retained Bridges and Bars ("SRBB") are used for the restoration of Straumann dental implants with different endosteal diameters, lengths and platforms (Figure 1). The purpose of this premarket notification is to expand the currently cleared abutment-to-implant interfaces to include the BLX implant system of the Straumann Dental Implant System (SDIS). The materials available include coron and titanium.
SRBB devices facilitate customization to meet the functional and esthetic requirements of the individual patient. They are patient-specific medical devices, i.e., they are designed by a dental professional (clinician or dental technician) and fabricated by Straumann specifically for an individual patient.
SRBB devices are designed via Computer Aided Design (CAD). After importing a scan of the patient model, Straumann® CARES® Visual software includes the ability to generate digital restoration models incorporating the subject devices as well as the predicate devices. The digital restoration model is transferred to the milling center where the restoration is produced using Computer Aided Manufacturing (CAM)techniques.
The provided document is a 510(k) Premarket Notification for the Straumann® CARES® Screw-Retained Bridges and Bars. The purpose of the submission is to expand the cleared abutment-to-implant interfaces to include the BLX implant system. This document does not describe an AI/ML-enabled device or a study involving human readers or expert consensus for ground truth. Instead, it describes a dental device and its performance is evaluated through bench studies, software validation, sterilization validation, and biocompatibility testing.
Therefore, many of the specific details requested in your prompt (e.g., acceptance criteria for AI performance, sample size for test set with data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone AI performance, training set details) are not applicable to this document as it pertains to a physical dental device, not an AI/ML system.
However, I can extract information related to the performance data and the conclusion about substantial equivalence.
Here's what can be extracted and inferred based on the document:
1. Acceptance Criteria and Reported Device Performance:
The document doesn't provide specific numerical acceptance criteria in a table format for this specific 510(k) submission's tests. Instead, it states that the device's substantial equivalence is addressed via bench studies that conform to FDA guidance and ISO standards. The "performance" is implicitly deemed acceptable if it meets these standards and supports the claim of substantial equivalence to the predicate device.
Acceptance Criterion (Inferred from testing) | Reported Device Performance (Implicitly Met) |
---|---|
Conformance to FDA Guidance: Root-form Endosseous Dental Implants and Endosseous Dental Abutments (May 12, 2004) for dynamic fatigue testing | Device passed dynamic fatigue testing |
Conformance to ISO 14801 (Dynamic fatigue testing) | Device passed dynamic fatigue testing |
Conformance to IEC 62304 (Software validation) | Software validated successfully |
Conformance to ISO 17665-1 and ISO/TS 17665-2 (Sterilization validation) | Sterilization validated successfully |
Conformance to ISO 10993-1 (Biocompatibility testing) | Biocompatibility testing passed |
Substantial Equivalence to predicate device (K132844) with expanded interface supporting BLX implant system | Determined to be substantially equivalent based on assessment of design and performance data. |
Study that Proves the Device Meets the Acceptance Criteria:
The study conducted to prove the device meets acceptance criteria consists of a series of bench studies and validations.
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: The document does not specify the exact sample sizes used for each of the bench tests (e.g., how many devices were dynamically fatigued).
- Data Provenance: Not explicitly stated, given it's a physical device and bench testing. It's implied that the testing was conducted by or on behalf of the manufacturer, Straumann USA, LLC (on behalf of Institut Straumann AG), a global company based in Switzerland with operations in the US. The tests are "bench studies," meaning they are laboratory-based, not clinical data from patients.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
- Not Applicable. This is a physical dental device. "Ground truth" in the context of AI/ML models (e.g., annotated images by experts) is not relevant here. The "truth" is established by adherence to engineering standards and material science principles, as verified through bench testing.
4. Adjudication Method for the Test Set:
- Not Applicable. As no expert review or human interpretation of data (in the AI/ML sense) is mentioned, no adjudication method would be used. The testing is based on objective measurements and conformance to standards.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
- No. This is not an AI/ML-enabled device or an diagnostic imaging device where human readers would interpret results. Therefore, an MRMC study is not relevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not Applicable. This is a physical medical device (dental implants/bridges), not a software algorithm or AI. While the design uses CAD/CAM software, the "performance" evaluated is that of the manufactured physical product, not the design software itself as a standalone diagnostic tool. The software validation mentioned (IEC 62304) ensures the design software functions correctly, but this is distinct from evaluating an AI algorithm's standalone diagnostic performance.
7. The Type of Ground Truth Used:
- Engineering Standards and Objective Measurements: The "ground truth" for evaluating this device's performance is based on established engineering standards (ISO 14801), regulatory guidance (FDA guidance on dental implants), and scientific principles for material performance. Tests performed include dynamic fatigue, software validation, sterilization validation, and biocompatibility testing. The outcome is whether the device meets the specified performance requirements under these conditions, not a "diagnosis" or "classification" like in an AI context.
8. The Sample Size for the Training Set:
- Not Applicable. This is a physical device, not an AI/ML model. Therefore, there is no "training set" in the context of machine learning.
9. How the Ground Truth for the Training Set was Established:
- Not Applicable. See point 8.

The Straumann CARES M-Series CAD/CAM System is indicated for the design and fabrication of single or multiple-unit implant-borne prosthetics for the restoration of partially or fully edentulous mandibles and maxillae. The system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners or Extra-Oral Scanners, CAD software, CAM software, restoration material blanks, milling machines and associated tooling and accessories. The system is used to design and fabricate CAD/CAM milled coping, crown and bridge restorations to be cemented onto Straumann® Variobase® Abutments, as well as milled abutments to be affixed to the endosseous dental implants of the Straumann® Dental Implant System using a basal screw.
The Straumann CARES M-Series CAD/CAM System is intended for the design and fabrication of dental restorations by dental laboratories by means of a digital workflow. The Straumann CARES M-Series CAD/CAM System employs optical impression files that document the topographical characteristics of teeth, traditional dental impressions, or stone models. The Straumann CARES Visual CAD software then allows the design of the desired restorations. The CAM software converts the digital restoration design into the tooling and tool path commands needed to fabricate the restoration. The CAM software also allows multiple restoration files to be combined (nested) in order to maximize the use of dental material blanks. The milling command file is encrypted prior to transfer to the M-Series mill; this encryption ensures that files generated using other CAD or CAM software cannot be used with the M-Series mill. The user will load the milling command file into the M-Series mill where it is decoded. The user loads the appropriate dental material blank and initiates the milling operation.
The provided document describes the acceptance criteria and the study that proves the Straumann CARES M-Series CAD/CAM System meets those criteria, primarily through a substantial equivalence comparison with predicate devices and various bench studies.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are not explicitly stated as numerical targets in the document. Instead, performance is demonstrated through a claim of "equivalence" to predicate devices, which implicitly means meeting the performance standards of those legally marketed devices. The reported device performance is presented as "Equivalent" for various features when compared to predicate devices.
Feature / Acceptance Criteria | Reported Device Performance (Equivalence Discussion) |
---|---|
Indications for Use (Straumann CARES M-SERIES CAD/CAM System vs. SIRONA DENTAL CAD/CAM SYSTEM) | Equivalent: The basic indication of providing support for prostheses scanning, design, and fabrication is the same. Support for TiBase-borne restorations is the same. The subject device indications refer to fabrication of coping, crowns, and bridges, including mesostructures (top-half of two-piece abutment), which are the same as referenced in the primary predicate indications. The crowns and bridges of the subject device are considered equivalent to hybrid abutments. The subject device also supports the fabrication of implant-connected solid abutments. This implies its performance meets the predicate for all these restoration types. |
Source of Input Files | Equivalent: Capabilities of the subject device (Intra-Oral Scanner, Bench-top Scanners) include the scope of capabilities for the predicate device (Bench-top scanners). |
Bench Scanner Control | Equivalent |
Implant Detection | Equivalent: Both use Scanbodies. |
Design Environment | Equivalent: Both are Closed CAD Systems facilitating the design of restorations, but for devices from different companies. Performance is considered equivalent in terms of design functionality. |
Restoration Types Supported | Equivalent: Capabilities of the subject device (Copings/Crowns for Variobase, Copings/Crowns/Bridges for Screw-Retained Abutments, Bridges/Bars for Variobase for Bridge/Bar, Solid TAN Abutments) include the scope of capabilities for the predicate device (Copings/Crowns for TiBase, Copings/Crowns for Camlog Titanium Base). Both allow design and fabrication of the mesostructure for two-piece abutments (standard coping or hybrid crown/bridge). The subject device also allows design and fabrication of a one-piece titanium abutment. The areas of the abutment available for design are equivalent. |
Supported Hardware Devices | Equivalent: Capabilities of the subject device (Straumann Variobase Abutments, Straumann Screw-Retained Abutments, Solid abutments) include the scope of capabilities for the predicate device (Sirona Ti-bases, Camlog Titanium Base). The subject devices provide support for implant-connected abutments. |
Supported Restorative Materials | Equivalent: ZrO2 Ceramic material with indications according to ISO 6872 Classification are equivalent. The ZrO2 materials for use with the Straumann CARES M-Series CAD/CAM System have been previously cleared by FDA. The TAN material is identical to material used in CARES TAN Abutments (K150899). Straumann n!ce Blocks for Amann Girrbach were previously cleared (K170420). The use of the Ivoclar IPS e.max CAD material with Variobase Abutments has been cleared (K142890). The use of the n!ce material with Variobase Abutments has been cleared (K170354). This implies the milling performance and material properties for these materials meet prior predicate standards. |
Restoration Sizes | Equivalent: Capabilities of the subject device (Single crown up to 16-Unit bridge) include the scope of capabilities for the predicate device (Single crown). Support of bridges through two or more implants is achieved through Variobase for Bridge/Bar abutments (K151157). Use of multiple implants in the bridge limit the force on the individual implant to be less or equivalent to that of the single crown. For a 16-unit bridge, the force is spread over 4 or more implants. |
Interface to Ti-Base | Equivalent: The ability of the subject device to use solid blocks provides greater design flexibility to the user (compared to predicate's pre-milled blocks). |
CAD to CAM Transfer | Equivalent: Seamless, same software interface. |
CAM Capability | Equivalent: Capabilities of the subject device (Nesting, selection of tools/paths/speeds/feed rates, encryption) include the scope of capabilities for the predicate device (selection of tools/paths/speeds/feed rates). |
CAM to Mill Transfer | Equivalent: Capabilities of the subject device (encrypted file format ensuring only Straumann CARES Visual and CAM Module files are accepted) include or exceed the scope of capabilities for the predicate device (expected transfer encryption). |
Supported Mills | Equivalent: Capabilities of the subject device (Straumann CARES M-Series Mills) include the scope of capabilities for the predicate device (CEREC MCXL Mill, inLab MCXL Mill). |
Fabrication Workflow | Equivalent: Capabilities of the subject device (Dry milling of partially crystallized ceramic, Wet milling of Ti-6Al-7Nb Pre-Milled Abutment Blanks, Ivoclar IPS e.max CAD, and n!ce Glass Ceramic) include the scope of capabilities for the predicate device (In-lab wet milling of pre-sintered ceramic blocks). |
Variobase Abutments: Indications for Use | Identical to predicate Straumann Variobase Abutments (K142890, K120822). |
Variobase Abutments: Ti-base Material | Identical: Titanium-Aluminum-Niobium alloy (Ti-6Al-7Nb). |
Variobase Abutments: Abutment Diameter | Identical: 3.8 – 7.0 mm. |
Variobase Abutments: Abutment Height | Identical: 3.5 – 4.5 mm. |
Variobase Abutments: Coping/Crown Material | Equivalent/Identical: Digital workflow is expanded to add additional materials (Ceramill ZOLID series, Ivoclar IPS e.max CAD, Straumann n!ce). The Zi, ZOLID series are equivalent to predicate's zerion ZrO2 material. Use of n!ce and IPS e.max CAD is identical to previously cleared devices. |
Variobase Abutments: Design Workflow | Equivalent: Subject employs a subset of predicate's techniques (CAD vs. Wax-up or CAD). |
Variobase Abutments: Fabrication Workflow | Equivalent: Restorations milled by the dental laboratory are equivalent to those produced by the Straumann milling center. |
Variobase Abutments: Mode of Attachment | Identical: Screw-retained or cement retained. |
Variobase Abutments: Reusable | Identical: No. |
Laboratory Milled CARES® TAN Abutments: Indications for Use | Identical to predicate Straumann® CARES® TAN Abutments (K150899). |
Laboratory Milled CARES® TAN Abutments: Abutment Material | Identical: Titanium-Aluminum-Niobium alloy (Ti-6Al-7Nb, TAN). |
Laboratory Milled CARES® TAN Abutments: Abutment Apical Design | Identical: Engaging, BoneLevel (NC, RC), Tissue Level (RN, WN). |
Laboratory Milled CARES® TAN Abutments: Abutment Coronal Design | Identical: CADCAM design process, designs controlled by material-specific design limits in CARES Visual CAD software, model verification by CAM software, and milling blank dimensions. |
Laboratory Milled CARES® TAN Abutments: CAD Design Limits | Identical: Max. Angulation 30°, Emergence Offset 0.1 mm, Emergence Angle 65°, Min. Thickness 0.4 mm, Smooth Distance 0.5 mm, Min post surface area 37 to 56mm². |
Laboratory Milled CARES® TAN Abutments: Fabrication Method | Equivalent: Both methods use Straumann CARES Visual CAD software for design, applying the same validated limits. The difference is the manufacturing location (QSR controlled vs. dental laboratory). The milling accuracy of the Straumann CARES M-Series CAD/CAM System has been validated. Labeling has been revised and validated for milling unit installation, maintenance, and required tools/machine liquids/material blocks to ensure equivalence. |
Laboratory Milled CARES® TAN Abutments: Directly Veneerable? | Identical: Yes. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify a separate "test set" sample size in the context of clinical studies with patients. The studies conducted are primarily bench studies involving laboratory testing of materials and device components. The number of samples for each type of bench test (fatigue, biocompatibility, etc.) is not detailed in this summary, but these are typically standardized tests with a defined number of specimens as per the relevant ISO or FDA guidance.
The data provenance is not explicitly stated as "country of origin" or "retrospective/prospective" clinical data, as it primarily refers to bench testing data. These tests would have been performed in a controlled laboratory environment.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts
This information is not applicable. The evaluations are based on engineering and material performance specifications (bench studies) and comparison to predicate devices, not on expert clinical review of a test set for establishing ground truth in a diagnostic sense.
4. Adjudication Method for the Test Set
This information is not applicable, as the evaluation is based on bench testing and comparison to technical specifications, not human adjudication of diagnostic 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
This information is not applicable. The device is a CAD/CAM system for fabricating dental prosthetics, not an AI-assisted diagnostic tool for human readers. Therefore, an MRMC study related to improving human reader performance with AI is not relevant to this submission.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
The document describes the Straumann CARES M-Series CAD/CAM System as an integrated system involving CAD software, CAM software, milling machines, and material blanks. The "algorithm" component is the CAD/CAM software. The system's performance is inherently "standalone" in its function of designing and fabricating prosthetics based on input scan files, but it is a tool used by human operators (dental technicians/laboratories). The bench studies performed evaluate the output of this system (e.g., strength of the milled prosthetics), which indirectly assesses the standalone performance of the algorithms and hardware in creating the physical restorations.
7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)
For the bench studies, the "ground truth" refers to established engineering and material standards. Specifically:
- Dynamic fatigue testing: Conforming to FDA guidance and ISO 14801. The ground truth is the performance criteria defined by these standards.
- Software validation: Conforming to the requirements of IEC 62304. The ground truth is compliance with this software safety standard.
- Sterilization validation: Conforming to ISO 17665-1 and ISO/TS 17665-2. The ground truth is achieving sterility assurance levels defined by these standards.
- Biocompatibility testing: Conforming to ISO 10993-1, ISO 10993-5, ISO 10993-10, ISO 10993-11, and ISO 10993-18. The ground truth is meeting the safety criteria for biological interaction.
- Electrical safety testing: Conforming to IEC 61010-1 and IEC 61010-2-010. The ground truth is compliance with electrical safety standards.
For the substantial equivalence comparison, the "ground truth" is the performance and characteristics of the legally marketed predicate devices.
8. The Sample Size for the Training Set
The document does not refer to a "training set" in the context of machine learning. The CAD/CAM software is likely based on computational design and manufacturing principles, not on a machine learning model that requires a labeled training set derived from large datasets of past cases. Therefore, this concept is not applicable here.
9. How the Ground Truth for the Training Set was Established
As there is no "training set" in the machine learning sense, this question is not applicable. The underlying principles for the software's functionality would stem from dental anatomical knowledge, engineering mechanics, material science, and manufacturing tolerances, which form the basis of its deterministic operation.

The Straumann® CARES® Abutments CoCr are indicated for single tooth replacement and multiple tooth restorations. The prosthetic restoration can be cemented or directly veneered/screw-retained.
Straumann® CARES® Abutments CoCr are used for the restoration of Straumann dental implant platforms RN (Regular Neck), WN (Wide Neck), NC (Narrow CrossFit), and RC (Regular CrossFit). The Straumann® CARES® Abutments CoCr allow for individual customization regarding function and esthetics. Straumann® CARES® Abutments CoCr are designed by the dental laboratory technician either by means of a conventional wax-up model that is subsequently scanned or by scanning the intraoral situation and designing the shape by using a Straumann-approved software (such as Straumann® CARES® Visual). The design data is then transferred to a Straumann central milling center where the fabrication of the customized abutment is carried out. The Straumann® CARES® Abutments CoCr can be directly veneered.
The provided text describes the regulatory filing for a dental implant abutment and does not contain information about an AI/ML device. Therefore, it's not possible to extract the requested details regarding acceptance criteria, study design for AI models, or expert ground-truthing. The document pertains to a traditional medical device (Straumann® CARES® Abutments CoCr) and its equivalence to predicate devices based on material, design, and mechanical performance testing.
However, I can extract the acceptance criteria and performance data for the traditional medical device as described:

The following information is not present in the provided document, as it describes a non-AI medical device:
- Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- 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)
- Adjudication method (e.g. 2+1, 3+1, none) for the test set
- 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
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The sample size for the training set
- How the ground truth for the training set was established
Additional Study Information (from the document for the traditional device):
