  • Patent number: 10603143
    Abstract: 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 ?g/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 ?g/(GPa×mm3) and consists of the polymerization product of a radically curable dental composition, which comprises a) 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.

  • Publication number: 20190247168
    Abstract: What is described is a milling blank having a continuous shade gradient for production of an indirect dental restoration, composed of resin or a resin-based composite. What is also described is a method of producing such a milling blank by mixing two differently coloured pastes with continuous variation of the mixing ratio of the two pastes during the dispensing operation.

  • Publication number: 20180271629
    Abstract: Described is a milling blank for producing an indirect dental restoration, composed of resin or a resin-based composite, containing water in an amount of at least 25% of the water sorption Wsp. Described is further a method for producing such a milling blank or a moulded part produced therefrom for use as an indirect dental restoration, a use of the water sorption method, a kit for producing indirect dental restorations and a method for indirect dental restoration.

  • Patent number: 9795541
    Abstract: The present invention relates to the use of free-radically curable compositions, comprising chain-like and/or cyclic and/or cage-type polysiloxanes substituted by free-radically polymerizable groups and having at least 3 silicon atoms and/or mixed forms thereof, disiloxanes substituted by free-radically polymerizable groups, optionally one, two, three or more free-radically curable monomers having no silicon atom, fillers, initiators and/or catalysts for free-radical polymerization, and also further customary additives, in additive manufacturing methods, preferably in stereolithography (SL) and digital light processing (DLP). The present invention further relates to the use of the cured free-radically curable compositions, preferably for production of dental products.
