FDA 510(k) Number: K230487 FDA certification, quality and safety certification! Introduction: Dental glass ceramics, main ingredients are Lithium Disilicate, through special process. Because of its simple, rapid crystallization process and the effect of ultra high aesthetic repair, as the CAD high intensity of repair materials selection. Translucency: high translucency (HT), low translucency (LT) Model: HT: A1, A2, A3, A3.5, A4,B1,B2,B3,C1,C2,C3,D2,BL1, BL2, BL3, BL4 LT: A1, A2, A3, A3.5, A4,B1,B2,B3,C1,C2,C3,D2,D3,BL1, BL2, BL3, BL4 Package: 5pcs/Box. Indications: Inlay Onlay Embellishment Partial dental crown Anterior crown Single chip bridge (≤ 3 units) The average biaxial bending strength after complete crystallization is 637.3Mpa, which has passed FDA certification and product inspection and is higher than the standard strength value specified in ISO6892:2008 Dental Ceramics. Its superior strength can be used to make a three unit bridge in the grinding area. Feature: 1. 99.9% extra pure raw materials extracted form natural minerals 2. Melted in self-developed platinum system, at temperature up to 1700℃ 3. Automatic block forming technology eliminating the need of grinding and polishing 4. Precision heat-treatment for optical grade glass nucleation and crystalization 5. Interlocking micro-structure with nanometer sized needle shape crystals 6. Human teeth like opalescence and fluorescence form rare earth elements Performance: Haze and Transparency Colorinmeter Calibrated Multi-Prosthesis Simulation Flexural Strength Test Fracture Toughness Text Vickers Hardness Test Material Safety Data Sheet Hazards identificationGHS Hazard Categories: The product is not classified according to the GHS regulation.Pictograms:NoneHazard information:NoneStorage:Store in a cool, dry place.Disposal:Dispose of contents and container in accordance with national regulations.Composition/composition information Chemical nameC.A.S.
