CEREC Cercon 4D CAD/CAM Blocks
Indications for CEREC Cercon 4D™ CAD/CAM Blocks are:
- Crowns and bridges in the posterior and anterior tooth region
- Bridges with a maximum of two pontics
- Inlays, onlays and veneers
CEREC Cercon 4D™ CAD/CAM Block are pre-sintered zirconia blocks composed of yttria stabilized zirconia, which are designed for CAD/CAM milling. The proposed CEREC Cercon 4D™ CAD/CAM Blocks possess a 3-dimensional contour of dentine powder to mimic the natural tooth build-up. The aim of the 3D contour technology is to achieve more aesthetic restorations than with blocks based on the current multi-layer technology. The CEREC Cercon 4D™ CAD/CAM Blocks are used for fabrication of a dental restoration. The CEREC Cercon 4D™ CAD/CAM Blocks are not provided as the finished, fully finished dental restoration. The blocks are single use, meaning that they can only be milled once and are not recommended for re-milling. The blocks are materials supplied to dental professionals that must be further processed/manufactured using CAD/CAM milling and subsequent sintering to fabricate all ceramic restorations and they are not intended to be reused as in the context of direct patient-applied devices and materials. Therefore, no reprocessing, cleaning or disinfection instructions apply because it is a dental material and not a finished dental restoration itself. After sintering of the restoration, the dental professional will finish the restoration via polishing or glazing, before insertion into the patient's mouth.

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 does not explicitly state the sample sizes for the physical property tests or the finished restoration evaluations. It mentions that testing was conducted "in accordance with ISO 6872:2015 (Dentistry - Ceramic materials)" and ISO 10993-5 for biocompatibility. The provenance of the data (country of origin, retrospective/prospective) is not specified, but it can be inferred that these are bench tests conducted in a laboratory setting for regulatory submission.
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 information is not provided. The "ground truth" for the physical properties is defined by the ISO standards themselves. For the "predetermined acceptance criteria" for finished restoration quality, the number and qualifications of experts involved in setting or evaluating against these criteria are not mentioned.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
The document does not describe any adjudication method. The testing appears to be based on physical measurements and evaluations against established standards, not on subjective interpretations requiring adjudication.

CERCON HT
Cercon® ht is indicated in the anterior and posterior segments for:
- crowns
- telescopic primary crowns
- multi-unit bridges (with no more than two pontics between abutment crowns)
Cercon® ht can be used as a substructure (framework) which is then veneered with a dental veneering ceramic or can be used for full-contour application (without veneering) as well. In the case of telescopic primary crowns the substructure is not veneered.
Cercon ht is a ceramic composed of partially sintered yttria stabilized zirconia powder (Y-TZP). It is supplied to the dental laboratory as a blank and then processed in the dental-laboratory by machining and subsequent sintering to full density. It can be veneered with a dental veneering ceramic or can be used as anatomically shaped full-contour crown or bridge without veneering. It is designed for anterior and posterior locations as a substructure (framework) for single-tooth or bridge type restorations. It can also be used for the preparation of telescopic primary crowns.
1. Table of Acceptance Criteria and Reported Device Performance
Test | Acceptance Criteria | Reported Device Performance |
---|---|---|
Mechanical Strength (Flexural Strength) | Similar to predicate device (Cercon Base) | "material has the same mechanical (flexural strength)... as the predicate device." |
Chemical Stability (Solubility) | Similar to predicate device (Cercon Base) | "material has the same... chemical stability (solubility) as the predicate device." |
Wear (of unveneered material itself) | Significantly lower abrasion compared to conventional veneering porcelain | "significantly lower compared to conventional veneering porcelain." |
Wear (of antagonist teeth opposed to unveneered material) | Significantly lower abrasion compared to conventional veneering porcelain | "significantly lower compared to conventional veneering porcelain." |
Fit of Large Bridges | Comparable to conventional metal cast frameworks | "comparable to conventional metal cast frameworks." |
Fitting Accuracy of Telescopic Primary Crowns | Good fitting accuracy | "a good fitting accuracy... is achieved." |
Surface Quality of Telescopic Primary Crowns | Good surface quality | "a good surface quality is achieved." |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample sizes used for each non-clinical test (flexural strength, solubility, wear tests, fit tests, telescopic primary crown tests). The data provenance is not specified regarding country of origin; however, the tests were "Non-Clinical Performance Data" and "bench tests and professional evaluations" performed to demonstrate substantial equivalence to a predicate device. This suggests lab-based, retrospective testing rather than prospective clinical trials.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
The document does not specify the number of experts or their qualifications for establishing ground truth. It mentions "professional evaluations" in the context of proving substantial equivalence but does not detail the methodology for these evaluations.
4. Adjudication Method for the Test Set
The document does not describe any specific adjudication method (e.g., 2+1, 3+1) for the test set. Given the non-clinical nature of the tests, adjudication for human-based assessment as seen in clinical trials would not typically apply. The evaluation seems to rely on direct measurement and comparison to established benchmarks or predicate device performance.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The submission relies solely on non-clinical performance data (mechanical and chemical property testing, wear tests, fit tests). The document explicitly states: "Clinical Performance Data. Not applicable."
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This question is not applicable to the device described. Cercon ht is a physical dental material (zirconia ceramic) and not a software algorithm or AI device that would have "standalone" performance in the context of human-in-the-loop assessments.
7. The Type of Ground Truth Used
The ground truth for the non-clinical tests appears to be based on:
- Established physical and chemical properties: Standardized measurements for flexural strength and solubility.
- Comparative data against predicate device: Evaluating if Cercon ht performs "the same as" the predicate Cercon Base for mechanical and chemical properties.
- Benchmarks against conventional materials: Comparing wear to "conventional veneering porcelain" and fit to "conventional metal cast frameworks."
- Qualitative assessments of fit and surface quality: "good fitting accuracy and a good surface quality."
8. The Sample Size for the Training Set
This question is not applicable. Cercon ht is a physical dental material, not an AI/ML model that requires a "training set."
9. How the Ground Truth for the Training Set Was Established
This question is not applicable as there is no training set for a physical dental material.

The provided text is a 510(k) summary for dental abutments, which outlines the device description, intended use, and substantial equivalence to predicate devices, but does not describe any studies with acceptance criteria or performance metrics in the way you've outlined.
This submission is for a medical device (Cercon® Abutments) and, based on the provided text, the FDA classified it as substantially equivalent to existing predicate devices. This typically means that the device's technological characteristics and intended use are similar enough to already-approved devices that extensive new clinical studies with defined acceptance criteria and performance reporting might not have been necessary for the 510(k) clearance process itself. The summary states that "We believe that the prior use of the components of the CERCON® ABUTMENTS in legally marketed devices, the provided, and the biocompatibility history support the safety and effectiveness of the CERCON® ABUTMENTS for the indicated uses." This suggests reliance on existing data for similar components, rather than new performance studies.

Instead, the submission primarily focuses on:
- Device Description and Intended Use: CERCON® CERAM EXPRESS Ceramic System is a glass/glass-ceramic mixture for veneering zirconia substructures in fixed prosthodontics.
- Technological Characteristics: It's a modification of an existing device (Cercon® Ceram S Porcelains, K022796) with changes to formulation, material form, and processing.
- Basis for Substantial Equivalence: The manufacturer asserts substantial equivalence based on the prior use of components in legally marketed devices, similarity in formulations, and data regarding modifications. This implies that the modifications did not introduce new questions of safety or effectiveness.
Therefore, I cannot populate the table or answer the specific questions regarding acceptance criteria, study details, sample sizes, expert qualifications, or ground truth establishment based on the provided document.
It's important to understand that for materials like this, "performance" is often demonstrated through mechanical and biocompatibility testing (e.g., flexural strength, bond strength, cytotoxicity) rather than clinical studies with human readers or AI algorithms as would be relevant for diagnostic imaging devices. Such tests would typically compare the modified device's properties to the predicate device or established standards. However, the details of these tests are not present in the provided summary.
Here's what can be inferred or stated about what is NOT present:
- Table of Acceptance Criteria and Reported Device Performance: Not available in this document.
- Sample Size and Data Provenance (Test Set): Not applicable or not reported for the type of comparison made. There is no "test set" in the context of human readers or AI performance.
- Number of Experts and Qualifications (Ground Truth): Not applicable.
- Adjudication Method: Not applicable.
- MRMC Comparative Effectiveness Study: Not conducted or reported. This device is a material, not a diagnostic tool requiring human reader interpretation or AI assistance in that sense.
- Standalone (Algorithm Only) Performance: Not applicable. There is no algorithm.
- Type of Ground Truth Used: Not applicable in the context of expert consensus, pathology, or outcomes data for a diagnostic algorithm.
- Sample Size for Training Set: Not applicable. There's no AI model being trained.

CERCON CERAM S PORCELAIN
Designed for use on zirconia (zirconium oxide) in single tooth or bridge type restorations. Applications include both anterior and posterior locations.
CERCON® CERAM S PORCELAIN is a dental ceramic veneering material developed for veneering Cercon zirconia or an equivalent zirconium oxide substructure for fixed prosthodontics devices that include both anterior and posterior crowns/bridges. The CERCON® CERAM S PORCELAIN System consists of Dentin/Transparent/Incisal, Liner/Opaque, Shoulder, and Correction/Glaze/Stain Porcelains. The final restoration matches more shades than the predicate device.
