Intended Use

Luminesse ZR Blanks are intended for CAD/CAM fabrication of all-ceramic ( no metal ) dental restorations. Luminesse ZR Blanks are partially sintered Yttria stabilized zirconia blanks for use as CAD/CAM milling blanks. They are isostatically cold pressed so they can be milled using any compatible CAD/CAM machine such as Sirona InLab by Sirona Dental Systems, LLC, Charlotte, NC or KaVO Everest by KaVo Dental, Lake Zurich, IL. After the ZR Blank is milled, it is sintered, causing the materials to densify into a high strength ceramic material which is suitable for dental inlays, onlays, crowns and bridges.

Device Story

Luminesse Zirconia blanks are high-purity, partially sintered, isostatically cold-pressed yttria-stabilized zirconia blocks/discs. Used as raw material for CAD/CAM milling systems (e.g., Sirona InLab, KaVo Everest) to manufacture dental restorations. Dental professionals machine the blanks into specific shapes (inlays, onlays, crowns, bridges) using CAD/CAM or copying techniques. Post-milling, restorations are sintered in an oven to achieve final density and high fracture toughness. The phase-stabilized zirconia prevents crack propagation. Final restorations are luted/cemented into the patient's mouth to repair damaged teeth. Device benefits include high strength, durability, and precise fit for all-ceramic dental appliances.

Clinical Evidence

Bench testing only. Performance was evaluated using ISO 6872 standards for flexural strength and chemical solubility (mass loss in 4% acetic acid). No clinical data was required as the device is identical in formulation and material composition to legally marketed predicate devices.

Technological Characteristics

Material: 99.9 wt% ZrO2 + Y2O3 + HfO2 + Al2O3 (3 mol% yttria-stabilized). Form factor: Isostatically cold-pressed blocks and discs in various dimensions. Processing: CAD/CAM milling followed by sintering. Standards: ISO 6872 for mechanical and chemical testing. Connectivity: None (standalone material).

Indications for Use

Indicated for the fabrication of all-ceramic dental restorations including inlays, onlays, crowns, and bridges for patients requiring dental repair.

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.

stabilized with 3 mol % yttria and therefore do not undergo the usual phase transitions associated with pure zirconia. This phase transformation "toughens" the zirconia and stops crack propagation, yielding high fracture toughness and high strength. The highest purity powders are used to make Luminesse Zirconia Blanks minimizing trace oxides. Luminesse Blanks are 99.9 wt% ZrO 2+ Y20 3 + HfO2 + A1203. The natural zirconia minerals HfO2, which is so similar in structure and chemical properties to zirconia, that it has no effect on product properties. A small addition of alumina minimizes hydrothermal aging.

Luminesse Zirconia Blanks are dental ceramic blanks designed for the manufacturing of substructures for ceramic dental appliances. The dental appliance is machined either by CAD/CAM machining or using the copying technique. All appliances are for the sole use of the particular patient only. A metal chuck is glued on the end of blank or a metal ring that holds it in the CAD/CAM machine which is used to machine the final dental restoration. After completion of the machining steps, the dental restoration is fired (i.e., sintered) in the oven to harden the ZrO 2.

Luminesse ZR Blanks are intended for CAD/CAM fabrication of all-ceramic ( no metal ) dental restorations. Luminesse ZR Blanks are partially sintered Yttria stabilized zirconia blanks for use as CAD/CAM milling blanks. They are isostatically cold pressed so they can be milled using any compatible CAD/CAM machine such as Sirona InLab by Sirona Dental Systems, LLC, Charlotte, NC or KaVO Everest by KaVo Dental, Lake Zurich, IL.

After the ZR Blank is milled, it is sintered, causing the materials to densify into a high strength ceramic material which is suitable for dental inlays, onlays, crowns and bridges.

By definition, a device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device, or has the same intended use and different technological characteristics. But, it can be demonstrated that the device is as safe and effective as the predicate device and the new device does not raise different questions regarding safety and effectiveness as compared to the predicate device.

### Intended Use:

Safety and Effectiveness:

{2}------------------------------------------------

As such, it has been shown in this 510(k) submission, that the differences between the Luminesse Zirconia blanks and the predicate devices do not raise any questions regarding their safety and effectiveness. The Luminesse Zirconia blanks as designed and manufactured are as safe and effective as the predicate device and therefore are determined to be substantially equivalent to the referenced predicate device. The tests methods Flexural Strength and Chemical Technological Characteristics: solubility were used on IPS e.max ZirCAD by Ivoclar (K051705). These test methods were followed by the International Standards Organization (6872). IPS e.max ZirCAD by Ivoclar (K051705) used the Biaxial Performance Criteria: Strength method to test Flexural Strength (ISO 6872). Chemical Solubility for mass loss was also tested according to ISO 6872 using the method of a 4% solution acetic acid.

Since the predicate and proposed devices are exactly identical in formulation, there is no need for further testing. They are made from the same materials and have the same intended use.

The 510K "Substantial Equivalence" Decision Making Process was followed as described herein.

- 1. The Luminesse ZR Blanks have the same intended use, to be luted/cemented into place as inlays, onlays, veneers or crowns and for use as bridge components to repair damaged teeth.
- 2. The technological characteristics of the Luminesse ZR Blanks are similar to those for predicate devices and those currently on the market. In addition, the technological differences if any are well understood in the Dental Industry. The use of computerized lathe systems to prepare the inlay or onlay in the Dental Office, also has been cleared by 510(k) . Reference: K950299, K972276, etc..
- 3. The material which make up the Luminesse ZR Blanks are well established in more demanding areas such as zirconia abutments anchored to a titanium surgical implant.
- 4. The FDA "Decision Making Process" chart was used for this submission.
