Luxer Shaded Zirconia blanks/discs are intended for use with CAD/CAM technology to produce all-ceramic dental restorations (full contour crowns and bridges) as prescribed by a dentist.
Luxer Shaded Zirconia blanks are pressed and sintered blocks of Yttria stabilized Zirconia for use in CAD/CAM milling machines. It comes in different thicknesses (12 mm - 20 mm) and classic VITA shades A-D. In order to achieve pigmentation, four basic color components are used from the TOSOH TZ-Series of zirconia {white, yellow, pink, and gray} that yield corresponding VITA shades (A-D). After the Zirconia block is milled, it is sintered into a high strength all ceramic material suitable for full contour crowns and bridges. The material is biocompatible, has a high flexural strength (>1100 Mpa), and is water insoluble. These characteristics meet the ISO standard 6872 for an esthetic dental ceramic material.
The provided text describes the acceptance criteria and a study proving the substantial equivalence of the Luxer Shaded Zirconia device to a predicate device, as required for a 510(k) submission.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Standard) | Reported Device Performance |
|---|---|
| Material Properties: | |
| Biocompatibility | Biocompatible (stated) |
| High Flexural Strength | >1100 Mpa |
| Water Insoluble | Water Insoluble (stated) |
| Conformance to Standard: | |
| ISO 6872 for esthetic dental ceramic material | Meets ISO 6872 for esthetic dental ceramic material |
| Substantial Equivalence: | |
| Same fundamental technology as predicate device (K112710 ZENO Zr) | Yes, based on comparative data |
| Same indications for use as predicate device | Yes, intended for all-ceramic dental restorations (full contour crowns and bridges) |
| Similar physical properties (flexural strength, biocompatibility, solubility) as predicate device | Yes, confirmed by ISO 6872 testing |
| Similar chemical properties as predicate device | Yes, confirmed by ISO 6872 testing |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: The document does not specify a distinct "test set" in the context of clinical or image-based studies. Instead, "non-clinical testing" was performed to validate the design and confirm conformance with ISO 6872:2008. The sample size for this non-clinical testing (e.g., number of specimens tested for flexural strength) is not explicitly stated.
- Data Provenance: The data comes from "non-clinical testing" and a "Standard Data Report (Form 3654)" in relation to ISO 6872. This indicates laboratory-based, retrospective testing of material properties rather than prospective clinical data. The country of origin of the data is not specified but is implicitly associated with the applicant, Continental Dental Ceramics, Inc. (USA).
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- This information is not applicable as the study described is a non-clinical, material properties comparison study for substantial equivalence, not a study involving expert assessment of images or clinical outcomes to establish ground truth.
4. Adjudication Method for the Test Set
- This information is not applicable as the study described is a non-clinical, material properties comparison study, not one requiring adjudication of expert opinions.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and its effect size.
- No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This submission focuses on the material properties and substantial equivalence of the zirconia blanks themselves, not on the performance of human readers with or without AI assistance.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done.
- No, a standalone algorithm-only performance study was not done. This device is a dental material (zirconia blanks), not an algorithm or AI system.
7. The Type of Ground Truth Used
- The ground truth used for evaluating the device's properties (flexural strength, biocompatibility, solubility, etc.) was established through laboratory testing against the requirements of the international standard ISO 6872:2008 for dental ceramic materials and comparison to the known properties of the predicate device.
8. The Sample Size for the Training Set
- This information is not applicable. There is no "training set" as this is a material science and engineering validation, not a machine learning or AI study.
9. How the Ground Truth for the Training Set Was Established
- This information is not applicable for the reasons stated above.

510(k) Summary
{1}------------------------------------------------
7. Intended Use
Luxer Shaded Zirconia blanks/discs are intended for use with CAD/CAM technology to produce all-ceramic dental restorations (full contour crowns and bridges) as prescribed by a dentist.
Substantial Equivalence 8.
Continental Dental believes that Luxer Shaded Zirconia blanks are substantially equivalent to other legally marketed devices in the United States, such as K112710 ZENO Zr, Wieland Dental + Technik Gmbh & Co. KG. Both Luxer Shaded blanks and the predicate device are made from porcelain powder (product code EIH) and exhibit similar physical and chemical properties.
In comparison to the predicate, using ISO standard 6872 the data from that testing concludes that both materials are fundamentally the same. They both have the same fundamental technology, indications for use, physical properties (flexural strength, biocompatibility, solubility) and other technical similarities.
Based on the comparative data, Luxer Shaded Zirconia is essentially the same as currently marketed devices for the same indication, with similar physical and chemical properties, and supports our claim for substantial equivalence.
ರು Non-Clinical Testing
Non-clinical testing was performed in order to validate the design against the company's specified design requirements for physical and chemical properties, as well as flexural strength, and to assure conformance with the voluntary design standard ISO 6872:2008. Please see attached Standard Data Report (Form 3654).
10. Biocompatibility
Biocompatibility testing was not performed since identical materials are used in the predicate device with the same type and duration of patient contact. Our device is comprised of identical materials and manufacturing methods as the predicate device and other legally marketed devices and does not introduce any new issues of safety or effectiveness.
11. Safety & Effectiveness
The successful prior use of the components of Luxer Shaded Zirconia product in legally marketed devices, the similarity of the formulations used in this device and earlier devices, and the substantially equivalence of Luxer Shaded Zirconia blanks to prior cleared devices support the safety and effectiveness of this product for the intended use.
{2}------------------------------------------------
It has been shown in this 510(k) submission that the difference between Luxer Shaded Zirconia discs and the predicate device do not raise any questions regarding its safety and effectiveness.
