Celtra Duo Starter Kit for Cerec Dentsply Sirona

CAD/CAM blocks made of lithium silicate ceramic reinforced with zirconium dioxide (ZLS) with microstructure. For the production of anterior and posterior crowns, veneers, inlays and onlays. The blocks are already definitively crystallized and can be processed in Sirona Cerec or inLab systems. Material processing can continue according to clinical requirements. Without firing, offering almost double the strength of conventional glass ceramics, or with glaze firing, which increases the strength to that of lithium disilicate. Individualizable and color-adjustable with Celtra Universal Stains.

• high percentage of glass with high translucency, opalescence and fluorescence, resulting in a vibrant chromatic effect and a chameleon effect;
• The addition of 10% ZrO₂ strengthens the glass matrix, ensuring high resistance and, therefore, the creation of safe and long-lasting restorations;
• The lithium silicate microcrystals allow for easy and rapid processing in the crystallized state.

CTE approx. 11.8 x 10⁻⁶K⁻¹ (25-500 °C); intrinsic flexural strength as supplied 420 N/mm², 210 N/mm² immediately after milling in Cerec MC XL and polishing, 370 N/mm² after glaze firing; modulus of elasticity approx. 70,000 N/mm²; Vickers hardness approx. 700 HV; fracture toughness 2.0 MPa

PACKAGE CONTENTS: (19 blocks of various colors, 1 glaze of 5 gr and 1 baking mat)
