High-strength, lithium disilicate pressable ceramic for all types of dental restoration. Each block is made using High Density Micronization (HDM) technology, producing excellent physical properties while retaining exceptional aesthetics. Lithium disilicate microcrystals are equally dispersed to fill the entire glass matrix compared to traditional larger crystals, allowing Initial LiSi Press to remain stable after multiple firings without distortion or drop in value. Lithium disilicate microcrystals are equally dispersed to fill the entire glass matrix compared to traditional larger crystals, allowing Initial LiSi Press to remain stable after multiple firings without distortion or drop in value. Virtually no reaction layer when divested, allowing cleaner presses. Low abrasion, wear resistant. Low translucency (One-Body Concept A, B, C, D or Layer) blocks compact colour line-up following the one-body concept.
