Dear Leonie Zeller:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

{1}------------------------------------------------

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (OS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

#### 4 Device Description

The edelweiss CAD/CAM BLOCK and the Ceramir CAD/CAM Block are hybrid glass blocks used for the fabrication of indirect single-tooth restorations using CAD/CAM technology. The edelweiss CAD/CAM BLOCK and the Ceramir CAD/CAM BLOCK are available in the three different variants T-BLOCK and i-BLOCK and five shades.

T-BLOCKs are highly translucent blocks that mimic the optical properties of natural enamel. C-BLOCKs are high chromatic blocks corresponding to the color shades A0, A1, A2 and A3. i-BLOCKs are highly translucent and highly chromatic blocks, which have a pre-produced Ti-base interface.

The uniqueness of the edelweiss CAD/CAM BLOCK and the Ceramir CAD/CAM BLOCK lies in the manufacturing process, in which a hybrid glass block is produced by the patented process of vitrification and laser sintering. As a result, the edelweiss CAD/CAM BLOCK and the Ceramir CAD/CAM BLOCK combines the properties of the current CAD/CAM systems in a single block. It has properties comparable to those of feldspar glass-ceramics.

#### 7 Non-Clinical Performance Testing

As part of demonstrating substantial equivalence of edelweiss CAD/CAM BLOCKs and Ceramir CAD/CAM BLOCKs to the predicate device, edelweiss dentistry products gmbh submitted final finished devices for extensive testing in accordance with recognized consensus standards and voluntary standards, as well as to the company's own internal test protocols.

Testing evaluated flexural strength, flexural modulus, compressive strength and biocompatibility of the subject device, as well as other related physical properties. The subject device passed all required testing.

#### Substantial Equivalence Summary / Conclusion 8

Based on available 510(k) information provided herein our edelweiss CAD/CAM BLOCKs and Ceramir CAD/CAM BLOCKs have the same intended use, indications for use and are fabricated into permanent tooth restorations using the same CAD/CAM manufacturing methods as the predicate device BRILLIANT Crios. In addition to that our edelweiss CAD/CAM BLOCKs and Ceramir CAD/CAM BLOCKs have the same clinical, biological and technological characteristics as the predicate device BRILLIANT Crios. Any minor differences in the materials used to make the subject device when compared to the predicate device have been successfully evaluated by edelweiss dentistry products gmbh through extensive performance and biocompatibility testing on their device. such that the information submitted to the FDA demonstrates that the subject device is as safe and effective as the predicate device and does not raise any new questions of safety and effectiveness. edelweiss CAD/CAM BLOCKs and Ceramir CAD/CAM BLOCKs, as designed and manufactured by edelweiss dentistry products gmbh, have been determined to be substantially equivalent to BRILLIANT Crios blocks.
