To produce crowns in the anterior and posterior area, veneers, inlays and onlays. The already completely crystalized blocks are ground in the Sirona Cerec or inLab systems. The material can be further processed according to the clinical requirements, either without firing with almost double the stability of conventional glass ceramic or with glaze firing increasing the strength up to the level of lithium disilicate. Can be individualized and characterized with the Celtra universal stains. Advantages: • High glass contents with high translucency, opalescence and fluorescence, therefore lively colour presence and chameleon effect; • ZrO2 contents of 10 % reinforces the glass matrix and caters for a high strength and thus for safe and durable restorations; • Very small lithium silicate crystals enable a fast and easy processing in the crystalized state. Physical data: CTE approx. 11.8 x 10-6K-1 (25-500 °C); flexural strength intrinsic on delivery 420 N/mm², 210 N/mm² directly after processing in the Cerec MC XL and polished, 370 N/mm² with glaze firing; modulus of elasticity approx. 70,000 N/mm²; Vickers hardness approx. 700 HV; fracture toughness 2.0 MPa√m; density 2.6 g/cm³; chemical solubility < 40 µg/cm² intrinsic, < 20 µg/cm² glaze; softening temperature approx. 800 °C; transformation temperature approx. 620 °C.
