Dental Lithium Disilicate Block CAD CAM B40 Glass Ceramic Block Fits MCXL Sirona

Selection of high-quality raw materials and fine craftsmanship, it has a simple and fast crystallization process, excellent mechanical strength, excellent processing performance and ultra-high aesthetic repair effect. Therefore, it has become the first choice for all-ceramic repair in CAD/CAM systems and is a best-seller in the world. The digital chairside is made of all-ceramic material. Easy to operate, patients can experience a convenient repair process Rapid crystallization, the first choice material for immediate repair High strength and non-collapse, suitable for the production of various restorations Highly transparent, restores the natural color of teeth Transparency: HT (high transparency)/LT (low transparency) Color: A1/A2/A3/A3.5/A4/B1/B2/C2/BL1/BL2/BL3/BL4 Size: B40 (40x15x15mm) · UniformityThe surface of the glass ceramic block for all-ceramic dentures is smooth to the touch, uniform in color, and free of impurities and foreign matter. · Bending strengthThe average biaxial bending strength of glass ceramics for all-ceramic dentures after complete crystallization is 637Mpa, which is higher than the strength standard value established in “GB 30367-2013 Dental Ceramic Materials”. Its superior strength can be used to produce three-unit restorations containing molar areas. body.
