The first lithium disilicate ceramic with HDM technology 

GC Initial® LiSi Press is the first lithium disilicate ceramic ingot with High Density Micronization (HDM), a technology unique to GC that provides exceptional physical properties and the most natural, life-like aesthetics. HDM uses equally dispersed lithium disilicate micro-crystals to fill the entire glass matrix rather than using traditional larger size crystals that do not take full advantage of the matrix structure. The result is the ultimate combination of strength and aesthetics, making GC Initial® LiSi Press perfectly suitable for all types of restorations through all levels of transparency. Most importantly, HDM technology helps ensure the product remains extremely stable, without distortion or drop in value, even after multiple firings.

GC Initial® LiSi Press has an extremely high density thanks to: • optimized components • a proprietary innovative new manufacturing technology (HDM technology)
