About
 

GC Initial® LiSi Block is a fully crystallized lithium disilicate block that delivers optimal physical and aesthetic properties without firing. This unique block features GC’s proprietary High Density Micronization (HDM) technology for CAD/CAM dentistry to deliver high wear resistance, smooth margins and aesthetic final results. This makes it an ideal time saving solution for single visit chairside treatment.

The unique ultrafine crystal makes it easy to grind and can be quickly milled in its fully crystallized stage. Thanks to GC Initial® LiSi Block’s exceptional properties, high gloss and natural opalescence can be obtained in few minutes by polishing only and restoration is then ready for luting. The aesthetics of your restoration will be maintained over time.

GC Initial® LiSi Block is available in four aesthetic shades and two translucencies. When more characterization is required, the GC Initial® ceramic line comprises fully synergistic aesthetic solutions.
