All Livento/Soprano dental ceramics meet the requirements of ISO 6872:2015.
The provided text describes a 510(k) premarket notification for a dental ceramic system (Livento® press, Soprano® 10, and Soprano®). The notification aims to demonstrate substantial equivalence to a predicate device, the DCceram System (K141400). The "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to the performance data presented to show compliance with relevant standards and justify substantial equivalence.
Here's a breakdown of the requested information based on the provided document:
1. A table of acceptance criteria and the reported device performance
The document states that the Livento/Soprano dental ceramic system meets the requirements of ISO 6872:2015. This standard sets the acceptance criteria for dental ceramic materials. While specific numerical acceptance criteria from ISO 6872:2015 are not explicitly listed in the document, the tested parameters and the general statement of compliance serve as the reported performance against those criteria.
Acceptance Criteria (Set by ISO 6872:2015) | Reported Device Performance (Compliance Statement) |
---|---|
Flexural strength requirements | The results show product compliance to the requirements of ISO 6872:2015. |
Chemical solubility requirements | The results show product compliance to the requirements of ISO 6872:2015. |
Coefficient of Thermal Expansion requirements | The results show product compliance to the requirements of ISO 6872:2015. |
Glass Transition Temperature requirements | The results show product compliance to the requirements of ISO 6872:2015. |
Radioactivity of 238U requirements | The results show product compliance to the requirements of ISO 6872:2015. |
The document explicitly states: "The results show product compliance to the requirements of ISO 6872:2015."
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document mentions testing was done on "a representative sample of the products." However, it does not specify the exact sample size used for the performance testing.
Regarding data provenance:
- Country of Origin: Not explicitly stated, but the submitter (Cendres+Metaux SA) is located in Biel/Bienne, Switzerland. The testing would logically be conducted by or for a company based in Switzerland, or a contract lab.
- Retrospective or Prospective: This is a performance testing study, not a clinical study on patients. It's a laboratory study to characterize the material, so these terms (retrospective/prospective clinical data) do not directly apply. It's a prospective laboratory evaluation of material properties.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This type of information (experts establishing ground truth) is typically relevant for studies involving human interpretation (e.g., medical imaging AI). For this submission, which focuses on the material properties of dental ceramics tested against a recognized international standard (ISO 6872:2015), the "ground truth" is defined by the physical and chemical properties of the material as measured by standardized laboratory methods, not by expert consensus. Therefore, this question is not applicable in the context of this device and submission.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
As this is a laboratory performance study of material properties, not a study involving human readers or interpretations needing adjudication, the concept of an adjudication method is not applicable. The "ground truth" is established by the measurements themselves, evaluated against the specified criteria of ISO 6872:2015.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No, an MRMC comparative effectiveness study was not done. This type of study is relevant for medical image analysis devices, particularly those involving Artificial Intelligence (AI) to assist human readers. The device in question is a dental ceramic material used by dental technicians to create restorations, not a diagnostic imaging device or an AI application. Therefore, this question is not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
No, a standalone performance study (in the context of AI algorithms) was not done. As stated, this is a material property evaluation, not an AI or software device. Therefore, this question is not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for this device is the physical and chemical properties of the dental ceramic materials, as measured and characterized by standardized laboratory testing methods in accordance with ISO 6872:2015. This is a material science "ground truth."
8. The sample size for the training set
This question is typically relevant for AI/machine learning models where data is used to train an algorithm. Since this is a submission for a physical dental material with performance verified through adherence to an international standard, there is no "training set" in the sense of machine learning. The testing performed is for verification and validation of the product's physical properties.
9. How the ground truth for the training set was established
As there is no "training set" in the context of this device submission, this question is not applicable.

- Removable restoration such as secondary structures on bars and telescopic crowns, transversal connectors, occlusal splints and denture bases.
Pekkton® Ivory is a semi-crystalline thermoplastic supplied in milling blanks and press blanks. By application of CAD/CAM milling or pressing technology according to the instructions for use, it can be used by the dental technician to manufacture permanent crowns, bridges and denture frameworks.
This document is a 510(k) premarket notification for a dental material called Pekkton® Ivory. It does not describe an AI/ML powered device, but rather a physical dental product. Therefore, the information requested about acceptance criteria and study proving the device meets the criteria, particularly regarding AI/ML specifics like MRMC studies, training/test sets, and expert adjudication, is not applicable to this document.
The document discusses the substantial equivalence of Pekkton® Ivory to a predicate device (BioHPP-breCAM.BioHPP) and a reference device (Pekkton® Ivory K123638). The "studies" mentioned are primarily non-clinical tests to assess biological, chemical, and physical properties of the material.
Here's an analysis of what is provided, framed as closely as possible to your request, but acknowledging the difference in device type:
1. Table of Acceptance Criteria and Reported Device Performance
The document provides a comparative table of technological characteristics between the predicate device (BioHPP-breCAM.BioHPP) and Pekkton® Ivory, along with relevant standards. These values serve as the "performance" data, and the comparison to the predicate and relevant ISO standards imply the "acceptance criteria."
Characteristic | Predicate Device (BioHPP-breCAM.BioHPP) | Pekkton® Ivory (Candidate) | Remarks / Implied Acceptance Criteria |
---|---|---|---|
Device Name | BioHPP- breCAM.BioHPP | Pekkton® Ivory | Comparable device type |
510(k) No | K152113 | K170102 | (Not a performance metric) |
Classification Name | Tooth shade resin material | Tooth shade resin material | Same classification name |
Product Code | EBF | EBF | Same code |
Regulation Number | 872.3690 | 872.3690 | Same regulation |
Intended Use | Fabrication of definitive crown and bridge frameworks with no more than 2 pontics and for definitive removable restorations. | Intended for use with fixed (crowns and bridges) and removable dental prostheses. | Comparable intended use |
Material | PEEK (Polyetheretherketone) | PEKK (Polyetherketoneketone) Titanium Dioxide | Both are Poly-aryl-ether-ketones (PAEK), considered comparable. |
Form | Granulate-Pellets, Disc | Press blanks, Milling blanks | Comparable forms |
Processing | Melt processing of thermoplastic (Heat and pressure) | CAD/CAM Milling, Melt processing of thermoplastic (Heat and pressure) | Comparable processing |
Melting Temperature | approx. 340°C | Approx. 363 °C | Comparable temperature |
Bond strength to veneering resins | 25.2 MPa | > 15 MPa | Standard ISO EN 10477:2004 requires 5 MPa. Pekkton® Ivory exceeds this. |
E-Modulus | approx. 4083 – 4630 MPa | approx. 5000 MPa | Compared against ASTM-D638. Value is within a comparable range. |
Flexural strength | 163 – 179 MPa | 200 MPa | Compared against ASTM-D790. Value is within a comparable range. |
Water absorption | 6.5 ug/mm3 | 8.7 ug/mm3 | Standard ISO 4049-2009 requires water sorption lower than 40 ug/mm3. Pekkton® Ivory meets this. |
Water solubility | 0.1 ug/mm3 | 0.2 ug/mm3 | Standard ISO 4049-2009 requires water solubility lower than 7.5 ug/mm3. Pekkton® Ivory meets this. |
Acceptance Criteria Statement: The document explicitly states: "Testing has shown that Pekkton® Ivory is equivalent in performance characteristics to the predicate device BioHPP. The acceptance criteria were met."
2. Sample size used for the test set and the data provenance:
- Sample Size: The document does not specify exact sample sizes for each physical/chemical test (e.g., how many specimens were tested for flexural strength). It refers to "non-clinical test data."
- Data Provenance: The tests were conducted according to international standards (ISO, USP, ASTM). The country of origin of the data is implied to be Switzerland, where CENDRES+METAUX SA is based. The data is "retrospective" in the sense that the testing was completed prior to the 510(k) submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This is not applicable as the "ground truth" for a physical dental material is established through objective, standardized physical and chemical tests, not through expert consensus on interpretations like medical images.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. Adjudication methods are relevant for subjective assessments, typically in image interpretation or clinical outcomes, not for objective material property testing.
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 for a physical dental material, not an AI-powered diagnostic device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is a physical device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" for this device is based on objective, quantitative measurements of physical and chemical properties (e.g., melting temperature, bond strength, flexural strength, water absorption/solubility) derived from adherence to established international standards (ISO, ASTM, USP).
- For biological risks, the "ground truth" or assessment of safety is based on biocompatibility testing against recognized standards (ISO 10993 series and ISO 7405).
8. The sample size for the training set:
- Not applicable. There is no concept of a "training set" for physical material properties in this context, as there is no machine learning model involved. The manufacturing process and material formulation are "trained" through R&D and quality control, but not in the AI/ML sense.
9. How the ground truth for the training set was established:
- Not applicable. See point 8. The "ground truth" for the material's properties is established through the test methods and standards mentioned in point 7.

The SFI-Bar® is intended to be used with the implant manufacturer's implant (TABLE a) to provide support for fixation of overentures.
The SFI-Bar® provides the connection between compatible dental implant systems for the fixation of removable overdentures. The SFI-Bar® consists of an implant adapter (abutment) and a stress-free bar for the fixation of removable overdentures. The implant adapter is screwed into the dental implant.
Here's an analysis of the provided text to extract information about acceptance criteria and the study proving compliance for the SFI-Bar® device:
The provided document describes the 510(k) premarket notification for the SFI-Bar® device, a dental implant abutment. It seeks to establish substantial equivalence to predicate devices, rather than proving performance against novel acceptance criteria in a comprehensive clinical study.
1. Table of Acceptance Criteria and Reported Device Performance
The submission states that the SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar® and that acceptance criteria were met. However, the document does not explicitly list specific numerical acceptance criteria for performance metrics. Instead, it relies on demonstrating equivalence to the predicate device.
The "Performance Data" section mentions:
- Validation of Sterilization for metallic components.
- Evaluation of the intended manual disinfection procedure with SFI-Bar® Retention inserts G.
- Application and functional testing based on literature research.
The key acceptance criterion seems to be: "The SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar®."
Acceptance Criteria (Implied) | Reported Device Performance |
---|---|
Sterilization validated for metallic components. | Validation of Sterilization has been conducted. |
Intended manual disinfection procedure evaluated. | Evaluation of the intended manual disinfection procedure with SFI-Bar® Retention inserts G. has been conducted. |
Application and functional testing consistent with predicate. | Application and functional testing based on literature research have been conducted. The test methods used were the same as in the predicate device. |
Overall performance equivalent to the predicate SFI-Bar®. | Testing has shown that the SFI-Bar® is equivalent in performance characteristics to the predicate SFI-Bar®. |
Device is safe and effective for its intended use. | The summary of technological characteristics indicates that the device is safe and effective for its intended use and performs as well or better than the predicate devices. |
Ability to provide support for fixation of overdentures with compatible implant systems. | The SFI-Bar® is intended to be used with the implant manufacturer's (TABLE A) implant to provide support for fixation of overdentures. (Supported by technical compatibility and material equivalence.) |
2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states: "Non-clinical test data was used to support the substantially equivalence claim. Clinical testing was not necessary."
This indicates that a "test set" in the sense of a patient cohort or a large sample for a clinical trial was not used for this submission. The testing performed was non-clinical.
- Sample Size for Test Set: Not applicable in the context of clinical or large-scale performance testing. The "test samples" mentioned in the context of "analysis of platforms to identify worst-case test samples" would likely refer to physical samples or configurations chosen for non-clinical engineering tests (e.g., sterilization, disinfection). The specific number of these non-clinical worst-case samples is not provided.
- Data Provenance: The submission is from Cendres+Metaux SA, Biel/Bienne, Switzerland. The non-clinical testing was conducted by the manufacturer, but the location where the tests were performed is not specified. The data is retrospective in the sense that it's based on existing designs and literature, and performed prior to this submission for regulatory clearance.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. As clinical testing was not performed and the submission relies on demonstrating substantial equivalence through non-clinical data and comparison to predicate devices, there was no "ground truth" to be established by experts in a clinical context for a test set. The validation and evaluation mentioned primarily concern manufacturing processes and materials.
4. Adjudication Method for the Test Set
Not applicable, as no clinical test set requiring expert adjudication was used.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
Not applicable. This device is a dental implant abutment, a physical medical device, not an AI or imaging diagnostic tool. Therefore, MRMC studies and AI assistance are irrelevant to this submission.
6. If a Standalone (i.e., algorithm only without human-in-the loop performance) Was Done
Not applicable. This is a physical medical device, not an algorithm or software.
7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)
Given the nature of the device and the submission, the "ground truth" relied upon is primarily:
- Engineering and material standards (e.g., ASTM F 136 for Titanium alloy).
- Performance characteristics of legally marketed predicate devices (K073628, K083876, K102382) as established through their prior regulatory clearances.
- Scientific literature research supporting application and functional principles.
- Validation of manufacturing processes (sterilization, cleaning).
There isn't "ground truth" in the sense of clinical outcomes or expert consensus on diagnostic interpretations.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/machine learning device that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. As there is no training set, there is no ground truth establishment for it.
In summary: The submission for the SFI-Bar® focuses on demonstrating substantial equivalence to existing predicate devices, leveraging non-clinical testing, material standards, and literature review. It does not involve new clinical trials, expert consensus, or AI performance metrics.

(Manufacturing processes and materials equivalent to predicate) | Packaging, materials and processes: "Produced on process orientated CNC machines. The last step is a validated cleaning process (same processes). Packaging: Dentalblister, non-sterile." The material is "Wrought Titanium-6Aluminium-4Vanadium ELI Alloy for Surgical Implant applications" conforming to ASTM F 136 (same as predicate). |
(Compatibility with specified implant systems) | Compatibility: The SFI-Bar® Abutment is designed to connect with various dental implant systems from Thommen Medical, Neoss, and Institut Straumann (specifically listed in Table 1). The development and manufacturing were done "in close cooperation with the implant companies" with Quality Agreements in place (Design Control, Change Control, Complaint Handling, and Post Market Surveillance). This implies successful compatibility testing was conducted to ensure proper fit and function with these diverse implant systems, similar to the predicate device's compatibility. |
(Safety for intended use) | "The summary of technological characteristics as well as the torque test, application and functional testing indicate that the device is safe and effective for its intended use and performs as well or better than the predicate devices." This is a general conclusion based on the non-clinical testing and comparison to the predicate, demonstrating that the device does not raise new questions of safety or effectiveness. This is the overarching "acceptance criterion" for a 510(k) submission seeking substantial equivalence. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: The document does not specify the exact sample sizes used for the torque tests, application testing, or functional testing. It only states that these tests were conducted.
- Data Provenance: The data is non-clinical test data. The country of origin of the data is not explicitly stated, but the applicant (Cendres+Métaux SA) is located in Switzerland. The testing was conducted to support a 510(k) submission to the FDA (USA). The study is retrospective in the sense that it relies on existing testing methodologies and comparisons to a previously cleared predicate device.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not applicable (N/A) as the study described is a non-clinical, bench testing study comparing the performance of a new device to a predicate device. There is no "ground truth" derived from expert review of cases or outcomes in a clinical context. The "ground truth" for the testing would be established by validated test methods and engineering specifications.
4. Adjudication Method for the Test Set
This information is not applicable (N/A) for the same reasons as point 3. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies involving interpretation of medical images or patient outcomes, not in bench testing of a dental implant abutment.
5. If a Multi-Reader, Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
This information is not applicable (N/A). The device described, the SFI-Bar® Abutment, is a physical dental implant component, not an AI or imaging diagnostic device. Therefore, an MRMC study and AI assistance effect size are irrelevant to this submission.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This information is not applicable (N/A). As mentioned in point 5, this is a physical dental device, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for this type of non-clinical device testing is engineering specifications, validated test methods, and the performance characteristics of the legally marketed predicate device. The goal is to demonstrate that the candidate device performs "as well or better than" the predicate device under the same test conditions. There isn't an "expert consensus," "pathology," or "outcomes data" ground truth in the clinical sense for this specific evaluation. The "worst-case test samples" were identified through analysis of platforms, indicating an engineering-based approach to defining test parameters.
8. The Sample Size for the Training Set
This information is not applicable (N/A). There is no concept of a "training set" in the context of this non-clinical bench testing for a physical dental device. Training sets are relevant for machine learning algorithms or similar data-driven models.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable (N/A), as there is no training set for this type of device submission.
