cameo KrystaFree CAD/CAM Block are based on cameo Lithium Disilicate with optimized and adjusted microstructure. Through the microcrystalline ceramics process to form a nano, meter-scale multiple morphology interlocking structure, no need to crystallize and milling edge continuity and stability. It simplifies the production process of denture, and is an “instant restoration” dental restorative material. Non-Latex Shelf Life: 20 years from manufacture date
