Product Information
GC Initial LiSi Block is a fully crystallised lithium disilicate block that delivers optimal physical and aesthetic properties without firing. 1-6 This unique block features GC’s proprietary High Density Micronisation (HDM) technology for CAD/CAM dentistry to deliver high wear resistance, smooth margins and aesthetic final results. 1-6 This makes it an ideal time saving solution for single visit chairside treatments.
The unique ultrafine crystal makes it easy to grind and can be quickly milled in its fully crystallised 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. 1-6* Optimised acid and wear resistance help to preserve the aesthetics of your restorations over time. 1, 3, 4, 5
GC Initial LiSi Block is available in six aesthetic shades and two translucencies. When more characterisation is required, the GC Initial™ ceramic line comprises fully synergistic aesthetic solutions.
