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.

Device Story

Luxer Shaded Zirconia blanks consist of Yttria-stabilized zirconia blocks (12-20 mm thickness) pigmented with TOSOH TZ-Series components (white, yellow, pink, gray) to match VITA shades A-D. Used in dental laboratories with CAD/CAM milling machines; milled blocks are sintered to create high-strength (>1100 Mpa), water-insoluble, biocompatible full contour crowns and bridges. Final restorations are placed by dentists to restore dental function and esthetics. Device relies on established material properties and CAD/CAM fabrication workflows.

Clinical Evidence

Bench testing only. Device validated against ISO 6872:2008 standards for physical and chemical properties, including flexural strength and solubility. Biocompatibility was established via equivalence to predicate materials.

Technological Characteristics

Yttria-stabilized zirconia; TOSOH TZ-Series pigments. Form factor: 12-20 mm blanks/discs. Material properties: >1100 Mpa flexural strength, water insoluble, biocompatible. Conforms to ISO 6872:2008. Processing: CAD/CAM milling followed by sintering.

Indications for Use

Indicated for patients requiring all-ceramic dental restorations, specifically full contour crowns and bridges, produced via CAD/CAM technology as prescribed by a dentist.

Regulatory Classification

Identification

Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.

#### 6. Description of Medical Device:

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.

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.
