Dentsply Celtra

New from Dentsply, CELTRA® is an all-ceramic CAD block with a threefold functional microstructure containing lithium metasilicate, lithium disilicate and lithium phosphate crystals. These properties provide CELTRA with a distinct advantage in three areas. The high glass content allows the material to have a chameleon-like effect in the mouth; the inclusion of 10% zirconia ensures that this ceramic remains strong even when it is subjected to the load that would be expected to be resisted in the mouth (data on file); and the zirconia is completely dissolved within the microstructure. This results in smaller crystallites compared to lithium-disilicate. CELTRA comes in CAD blocks suitable for wet grinding in systems like CEREC and inLab in a precrystalised form and doesn’t require any additional crystalisation, therefore the processing time is reduced.
