ZENOFLEX DIMENSION
Zenoflex dimension is a dental ceramic, which is suitable for veneering hard-sintered zirconium dioxide frameworks with a coefficient of thermal expansion (CTE 25-500°C) of approx. 10.5 x 10° K 1.
Zenoflex dimension is a dental porcelain system that consists of about 150 different ceramic powders and it is intended to be used by professional dental technicians to manufacture all-ceramic dental appliances for the sole use of particular patients. Zenoflex dimension is recommended for veneering zirconium dioxide (ZrQs) frameworks with a coefficient of thermal expansion [CTE ¿25-500°C]] of approximately 10,5 x 10° Ki¹.
The Zenoflex dimension ceramic offers the dental technician the possibility to chose between different kinds of laver techniques considering aesthetical and economical aspects.
The "One layer technique", which is a fast and simple procedure to manufacture ceramic restorations, considers primarily the economical aspects. For manufacturing ceramic restorations the user needed numerous types of ceramic (dentine and incisal ceramics) so far. But now less types of ceramic are necessary for manufacturing anatomical crowns or bridges and for achieving the desired dental colour.
The "Three layer techniques" enable the user to achieve a dental restoration with a more aesthetical result, because this layer technique comprises the application of at least three different types of ceramic.
With the "Professional layer technique" the dental technician can carry out an extended professional build-up to achieve a dental restoration with the most aesthetical result.
Furthermore the Zenoflex dimension ceramic enables the user to manufacture dental restorations with colours of the "VITA Toothguide Classical" as well as of the "VITA Toothguide 3D-Master".
This is a 510(k) summary for a dental ceramic device (Zenoflex dimension). The provided document does not contain the sort of detailed study information (acceptance criteria, specific performance metrics, sample sizes, ground truth establishment, expert qualifications, etc.) that would be found in a study report for device performance evaluation as typically done for AI/ML-enabled medical devices.

ZENOSTAR MAGIC GLAZE
The spray glaze ZENOSTAR Magic Glaze is a ready to use and easy to apply, spray on ceramic glaze, which is primarily intended for ZENOSTAR Zr restorations, manufactured with the help of the ZENOTEC Systems. However, veneered zirconium oxide restorations, (ZIROX and ZENOFLEX dimension) and metal ceramic restorations (REFLEX and REFLEX dimension) can also be glazed with the spray glaze ZENOSTAR Magic Glaze. ZENOSTAR Magic Glaze spray glaze can be used together with and/or at the same time as the relevant specific ceramic stains.
ZENOSTAR Magic Glaze is dental porcelain, which is made of glass frit and is applied in an aerosolized form. It can be used by professional dental technicians to glaze dental porcelain -fused-to-metal as well as all-ceramic restorations, like milled zirconium dioxide crowns and bridges.
This application method decreases the production time compared to the conventional build-up methods, where glaze ceramic powder has to be mixed with suitable liquids and layered onto the restoration with a brush.
After spraying on, ZENOSTAR Magic Glaze has to be fired at about 900°C for 1-2 minutes in a ceramic furnace to achieve its final properties.
Generally, the glaze bake determines the surface finish of the ceramic veneer and thereby significantly affect the esthetical appearance of the restoration. ZENOSTAR Magic Glace allows spraying on even and very thin layers of glace material, thus providing the possibility to control shining and optical reflection of the restoration by repeating the procedure.
It can be applied on single unit or multiple unit restoration at one time, and, in addition, it can be sprayed over unfired ceramic stains and body-stains, which are often used to match the color of the patient's natural teeth. These possibilities save time of additional firing cycles and enhance the efficiency of the application of ZENOSTAR MAGIC Glaze.
The provided text is a 510(k) summary for ZENOSTAR Magic Glaze, a dental ceramic spray glaze. It details the device's description, intended use, and comparison to a predicate device for the purpose of demonstrating substantial equivalence.
However, the document does not contain specific acceptance criteria for performance metrics, nor does it detail a study that proves the device meets such criteria in terms of quantitative performance (e.g., accuracy, sensitivity, specificity, or improvement in human reader performance).
Instead, the document asserts substantial equivalence based on the device's physical, biological, and chemical properties meeting demands of international accepted standards (like ISO 6872 for bending strength, and ISO 7405 for biocompatibility).
Therefore, I cannot provide a table of acceptance criteria and reported device performance from the given text because such specific performance criteria and a study to prove them are not present. The document focuses on demonstrating equivalence through material properties and intended use.
Here's a breakdown of what can be extracted or inferred based on the questions, even if direct answers for performance criteria and a specific study are absent:

ZENO AI ECO DISC
ZENO® Al cco Discs are milling blanks from which single copings and primary components for anteriors and premolars can be made. These are intended for use as ceramic frameworks for dental prosthetics.
ZENO Al eco Discs are milling blanks composed of pure aluminium oxide. They are intended to be used by professional dental technicians for making single copings and primary components for anteriors and premolars to apply them as ceramic frameworks for dental prosthetics for the sole use of particular patients. ZENO Al eco Discs can be machined in all machines of the ZENO Tec system. The manufacturing process of this ceramic framework consists of different steps. At first the model has to be scanned. In the next step, the restoration has to be designed virtually with the help of the CAD technology. Thereafter, the realization of this design has to be carried out by the CAM technology. In a final step after hard sintering of the ZENO Al eco, the framework can be veneered with a suitable veneering ceramic.
This document is a 510(k) summary for the ZENO Al eco Disc, a dental milling blank. This type of submission focuses on demonstrating substantial equivalence to a predicate device rather than conducting a full clinical trial with acceptance criteria for a new AI/software device. Therefore, many of the requested categories related to AI performance studies are not applicable or cannot be extracted from this document.
Here's an analysis of the provided text in relation to your request:
1. A table of acceptance criteria and the reported device performance
This document does not specify quantitative acceptance criteria or device performance data in the way an AI/software device submission would. Instead, it relies on demonstrating equivalence to a predicate device based on material properties and intended use.
Acceptance Criteria (Not explicitly stated for a new AI device, but implied for equivalence) | Reported Device Performance (as stated for equivalence) |
---|---|
Material Composition Equivalence | Both ZENO Al eco Discs and the predicate (inCoris AL) are based on Aluminum oxide. |
Indications for Use Equivalence | Both have similar indications for use. |
Physical, Biological, and Chemical Properties Equivalence | Both have comparable physical, biological, and chemical properties. |
Safety and Effectiveness Equivalence | ZENO Al eco Discs possess "high-level safety and effectiveness" due to excellent material properties; performs "as well as or better than the predicate device." |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
N/A. This is a material-based dental device, not an AI/software device requiring a test set of data for performance evaluation. The submission relies on laboratory testing of material properties, not a "test set" of patient data.
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)
N/A. Not applicable to this type of device submission. Ground truth, in the context of AI, involves expert-level annotations or diagnoses, which is not relevant here.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
N/A. Not applicable to this type of device submission.
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 is not an AI-powered device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
N/A. This is not an AI-powered device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For a material-based device like this, "ground truth" typically refers to established standards for material properties (e.g., strength, biocompatibility) as assessed through standardized laboratory tests. The document implies that these properties were tested and found to be comparable to the predicate device, but specific details of these tests are not provided in the summary.
8. The sample size for the training set
N/A. This is not an AI/machine learning device. The "training" for such a device would involve optimizing the manufacturing process to achieve desired material properties, not training an algorithm on a dataset.
9. How the ground truth for the training set was established
N/A. Not applicable to this type of device submission.

ZENO PMMA DISC
ZENO®PMMA Discs are milling blanks consisting of polymethylmethacrylate. They are designed for making long-term temporary crown and bridge work and have to be machined with the CAD/CAM technique. ZENO PMMA Discs are recommended for manufacturing substructures of single tooth and bridgework with one or two pontics.
ZENO PMMA Discs (A3/B1) are milling blanks composed of hot cured polymethylmethacrylate (PMMA). They are intended to be used by professional dental technicians for making long-term temporary crowns and bridgeworks for the sole use of particular patients.
ZENO PMMA Discs can be machined in all machines of the ZENO Tec system. The manufacturing process of the long-term temporary crowns and bridges consists of different steps. At first the model has to be scanned. In the next step, the restoration has to be designed virtually with the help of the CAD technology. Thereafter, the realization of this design has to be carried out by the CAM technology. In a final step the restoration can be individually characterised with dental veneering composites for improving the aesthetics and it can be pre- and high shine polished.
The ZENO PMMA Discs are offered in two different shades (A3, B1) and thicknesses.
The provided document is a 510(k) summary for a dental device (ZENO PMMA Disc). It does not contain information about acceptance criteria for device performance, nor does it describe a study proving the device meets specific performance criteria.
Instead, the document focuses on demonstrating substantial equivalence to a legally marketed predicate device (VITA CAD-TEMP). This is a different regulatory pathway than providing detailed performance studies against defined acceptance criteria.
Therefore, most of the requested information cannot be extracted from this document. However, I can provide what information is available based on the request:
1. A table of acceptance criteria and the reported device performance:
- Not Applicable: The document does not provide specific acceptance criteria or performance data for the ZENO PMMA Disc. It asserts "comparable physical, biological, and chemical properties" to the predicate device but does not quantify these or establish specific criteria.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Not Applicable: No clinical or laboratory performance study against specific criteria is described, so no test set sample size or data provenance is mentioned.
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: No ground truth establishment activity for a test set is described.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not Applicable: No adjudication for a test set is described.
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 a material science device, not an AI or imaging device, so an MRMC study is irrelevant and not mentioned.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not Applicable: This is a material science device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- Not Applicable: No ground truth used for performance evaluation is described. The "ground truth" for regulatory submission in this case is the predicate device's established safety and effectiveness.
8. The sample size for the training set:
- Not Applicable: This is a material science device, not an algorithm that requires a training set.
9. How the ground truth for the training set was established:
- Not Applicable: As above, no training set or ground truth for it is relevant or mentioned.
Summary of available information related to equivalence, as described in the document:
The regulatory submission asserts substantial equivalence based on:
- Identical indication for use: ZENO PMMA Discs and the predicate (VITA CAD-TEMP) are both used for making long-term temporary crowns and bridgeworks.
- Comparable material properties: Both devices are acrylate polymers and "have comparable physical, biological, and chemical properties." (No specific data provided in this summary to quantify "comparable").
- Similar function: Both devices have the "same prophylactic, diagnostic and aesthetic function."
The document states: "Due to the high polymerization grade and excellent material properties of the ZENO PMMA Discs, the restorations possess a high-level safety and effectiveness. ZENO PMMA Discs therefore are as safe, as effective, and performs as well as or better than the predicate device." This is the core argument for substantial equivalence rather than a detailed performance study against acceptance criteria.
