The device description focuses on the material properties and manufacturing process (CAD/CAM milling and sintering) of zirconia blanks, with no mention of AI or ML for analysis, diagnosis, or treatment planning.
No.
A therapeutic device is one that performs an action to treat a disease, injury, or condition. This device is a blank used to create prostheses (dentures, crowns, and bridges) which are restorative rather than therapeutic.
No
The device is a material (zirconia blanks) used to create dental prostheses, not to identify or diagnose a condition or disease.
No
The device is a physical zirconia blank used for creating dental prostheses, which is a hardware component. While it is processed using CAD/CAM (which involves software), the device itself is the blank material, not the software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to create dental prostheses (dentures, crowns, and bridges) for prosthetic dentistry. This is a restorative and structural application, not a diagnostic one.
- Device Description: The device is a material (zirconia blanks) that is processed and used to replace or restore teeth. It does not perform any tests on biological samples to provide diagnostic information.
- Lack of Diagnostic Function: There is no mention of the device being used to detect, measure, or analyze any biological substances or markers for the purpose of diagnosing a disease or condition.
- Performance Studies: The performance studies focus on the material properties and mechanical strength of the finished product, which are relevant to its use as a dental prosthesis, not as a diagnostic tool.
IVD devices are typically used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

Device Description
Shaders™ Zirconia are disc shaped dental porcelain zirconia oxide blanks that come in different sizes that are used in custom restorations by the dental laboratory. The dental laboratory will further process the blank by milling the blank based upon the anatomically rendering of the patient's teeth (done at the dental office) through "Computer Aided Drafting/ Computer Aided Machining (CAD/CAM)". Once the custom rendered blank is milled the product is fully sintered and colored (if required) and fitted to the patient's teeth as dentures, crowns or bridges.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Digital Age Dental Laboratories performed a series of tests to assess whether the device is safe and effective to use. Sintered tests coupled with mechanical bench testing confirmed that the device meets specifications including established international standards and guidance documents. Density, bending strength, fracture toughness, chemical solubility and material characterization/composition of finished product was conducted to confirm that the product is safe and effective, while meeting performance goals established by standards. Shaders™ Zirconia blanks comply with ISO 6872:2008, "Dentistry – Ceramic materials" and ISO 13356: 2008, "Implants for surgery, Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP)".

Dear Tim Mckimson:
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 (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 located 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.
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
1
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 803) for devices or postmarketing safety reporting (21 CFR 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 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
