Amber Mill is the first machinable dental glass-ceramic blocks made of lithium disilicate. Its reinforced mechanical properties and aesthetic values with qualified machinability are greatly advantageous for patients and clinics. Denser and more crosslinked crystal structure of Amber Mill results in superior physical properties. Biaxial flexure strength of Amber Mill is about 10% higher than comparative product after it is fully crystallized. Outstanding machinability of Amber® Mill is evidently affirmative when checking the edges of the milled restorations. Highly stable edges with less chipping occurrence prove that Amber Mill is the best machinable lithium disilicate block for CAD/CAM system.
