Dental milling blank for the production of permanent indirect restorations and computer-aided process for producing the permanent indirect restorations

摘要

A dental milling blank for the production of permanent indirect restorations in the CAD/CAM process, characterized in that it has a water sorption WSP of less than/equal to 18 μg/mm³, measured according to ISO 4049 and an E modulus E greater than/equal to 13 GPa, measured according to the ADA specification No. 27 and a quotient Q of WSP/E of less than 1.35 μg/(GPa×mm³) and consists of the polymerization product of a radically curable dental composition, which comprisesa) inorganic fillers, wherein the total mass of the inorganic fillers is at least 83 wt. %, based on the total mass of the composition,b) radically polymerizable monomers,c) one or more initiators for radically curing.
