The 510(k) summary describes a material (ceramic blocks) and the methods for fabricating dental restorations (hot press or CAD/CAM). There is no mention of AI or ML in the intended use, device description, performance studies, or key metrics. The technology described is traditional dental material processing and fabrication.
No
The device is a material (ceramic blocks) used to fabricate dental restorations, not a device that directly treats a medical condition.
No
The device is described as materials used to fabricate dental restorations, not to diagnose a medical condition.
No
The device description clearly states it is a physical material (glass ceramic blocks) used for fabricating dental restorations, not a software program.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for fabricating dental restorations (veneers, crowns, etc.) using hot press or CAD/CAM systems. This is a manufacturing process for a medical device that will be placed in the patient's mouth.
- Device Description: The device is a ceramic block used as a material for creating dental prosthetics. It's a raw material for fabrication, not a test or assay performed on a biological sample.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's health condition.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a material used to create a dental restoration, which is a therapeutic device, not a diagnostic one.

Device Description
Dental Lithium Disilicate Glass Ceramic Block (Up. Press Series and Up. CAD Series) are derived from dental porcelain powder that has been processed into their final net shapes. These blanks are then being further fabricated (using hot press or CAD/CAM technologies) into all-ceramic restorations such as veneers, inlay/ onlay, partial crowns, anterior crowns, posterior crowns. The ceramics material is composed of SiO2, Li2O, P205, Al2O3, B2O3, and other oxides. It also contains inorganic pigments (Er2O3, V2O3, and MnO2) to provide different shades on the product surface. The performance of this lithium silicate dental blank conforms to ISO 6872. Dentistry: Ceramic Materials

Our device is very similar to the predicate device in terms of indications for use, design, material (same material vendor), and processing between our device and the predicate devices. There are three minor differences that are worth discussing:
- (1) Compared with predicate device. the subject device has a slight different phrasing of potential dental applications in the Indications for Use Statement. This difference in wording is minor, and all applications for the subject device is compliant to the recommended clinical indications in Table 1 of ISO 6872: 2008
- (2) The subject and predicate device have slight difference in composition. But they both have silicate and alkaline metal oxide as the major component. For example, the subject device has SiO2, Li2O, K2O, and the predicate device has SiO2, Na2O, K2O. Note that lithium and sodium belong to the same group of alkaline metals and display very similar physical and chemical properties.
- (3) The predicate device will be CAD/CAM processed at dental labs, and the subject device can be either CAD/CAM processed or hot pressed. It has long been proven in the industry that CAD/CAM processing and hot pressing are similar in terms of product final physical and chemical properties. This is also demonstrated in our performance testing that products from the Up. Press and Up. CAD series are almost equivalent in performance (see Table 12.2 below).
The following table shows similarities and differences of the key performance between our device and the predicate devices. Tests were conducted following applicable procedures outlined in the FDA recognized consensus standard of ISO 6872, and results met all relevant requirements in the test standards, and are comparable to the predicate device in performance.
The only minor difference is that subject device has higher flexural strength and potentially wider dental applications compared with predicate device.
