GC Initial™ LiSi Press is a high-strength lithium disilicate ingot with proprietary HDM (High Density Micronization) technology that equally disperses micro-crystals—rather than traditional larger-size crystals—to fill the entire glass matrix, resulting in excellent physical properties and esthetics. It has a biaxial flexural strength of > 500MPa and virtually no reaction layer when divested. The material is wear resistant, stable after multiple firings and optimized for use with GC Initial™ LiSi veneering ceramic and GC Initial™ Lustre Pastes NF.

Additional features of GC Initial™ LiSi Press include:

•    Amazing aesthetics
•    Low abrasion and wear resistance
•    Seamless learning curve
•    Low chemical solubility
•    Rich, warm and bright colors

“It’s a really great product,” said Lucas Lammott, owner of M31 Dental Studio, in a webinar he hosted on the product. “It’s really quite an improvement over what we’re all used to.”

Lammott added that GC Initial™ LiSi Press is a product worth the enthusiasm it has created. “A lot of people think it’s just something new, but there’s actually some science behind why it’s better.” He explained GC Initial™ LiSi Press’s particle size is smaller and more condensed than competitors’ products, which contributes to its strength and flexibility, making it “overall just a real pleasure to work with.”

Lammott added the lack of a reaction layer is a particularly noteworthy feature of the product, as its absence allows the clinician to really refine the margins of the restoration, making the restoration process much more efficient. He said dental professionals have become accustomed to having to deal with a reaction layer, but that’s not necessary anymore.

“It is really nice not to have to deal with that anymore,” he said.

In addition, with GC Initial™ LiSi Press, you can get the color you need; it creates rich, warm and bright colors with excellent fluorescence. GC Initial LiSi Press is available in four translucencies:

•    HT (enamel replacement)
•    MT (press and stain)
•    LT (one body concept A, B, C, D or layer)
•    MO (layering)
