Discover GC Initial® LiSi Press, the ceramic system with the beauty & strength dentists demand without being low in value.
Lithium disilicate is a glass ceramic with proven clinical success, and is known for its excellent combination of strength and aesthetics. GC has now further optimized these qualities thanks to our proprietary innovative fabrication technology used in GC Initial® LiSi Press, a high-strength lithium disilicate ceramic material with HDM (High Density Micronization) technology.
GC has over 15 years of experience with dental ceramics, with its already proven GC Initial® ceramic line that is well-known among dental technicians worldwide.

The first lithium disilicate ceramic with HDM technologyGC 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, strong and aesthetic for the longevity of your patients smile.

The next generation Lithium DisilicateExceptional strength thanks to HDM technologyLithium disilicate micro-crystals are equally dispersed within the glass matrix for a homogeneous fill and a higher crystal density. This has resulted in high biaxial flexural strength of >500 MPa and excellent polishability. Moreover, the fine structure will contribute to minimize the wear of the antagonist teeth.

Bright & Natural AestheticsGC Initial® LiSi ceramic has vibrant and warm color tones with excellent fluorescence, similar to natural teeth, for very lifelike restorations under any light source, even in the evening. The color remains stable after multiple firings, making it possible to adapt the shade even after the first try-in. The stability of the material will also ensure long-term aesthetic results.

Excellent marginal adaptationThanks to the homogeneous structure of the evenly dispersed micro crystals, GC Initial® LiSi ceramic is less prone to marginal chipping.
The excellent marginal adaptation contributes to clinical longevity and long-lasting aesthetics.

High versatility: One ceramic for any of your IndicationsThe exceptional strength and amazing aesthetics make GC Initial® LiSi Press suitable for ultra-thin veneers as well as for single tooth restorations and small bridges, in both the anterior and posterior and on implants.
Thanks to the four translucencies of GC Initial® LiSi Press, beautiful results can be obtained, regardless of the thickness of the preparation and the color of the abutment.
