  • Publication number: 20230192925
    Abstract: What is described is a dental light-curable composition for elective production of a visible restoration in the anterior region or for filling of a cavity in the posterior region, comprising a total amount (A) of free-radically polymerizable monomers, where this total amount (A) consists of one, two, three or more than three free-radically polymerizable monomers and has a refractive index nA, 470nm in the range from 1.470 to 1.560, a total amount (B1) of nonaggregated and nonagglomerated inorganic filler particles having a particle size in the range from 7 to 70 nm, where this total amount (B1) has a refractive index nB1, 470nm in the range from 1.460 to 1.570 and where this total amount (B1) is in the range from 10 to 30 percent by volume, based on the overall dental light-curable composition, a total amount (B2) of inorganic filler particles having a particle size in the range from 0.12 ?m to 10 ?m, where this total amount (B2) has a refractive index nB2,470nm in the range from 1.450 to 1.

  • Patent number: 9833387
    Abstract: The present invention relates to a kit for indirect production of composite inlays, comprising a polymerizable material for production of a dental model, a polymerizable material for production of an inlay, a polymerizable material for luting of a crosslinked and non-sand-blasted, non-silanized, non-etched, non-primed and non-roughened composite inlay, the surfaces of which have been fully polymerized, in the cavity. Also disclosed is a polymerizable material for increasing the bond strength between the polymerizable material for luting of a crosslinked non-sand-blasted, non-silanized, non-etched, non-primed and non-roughened composite inlay, the surfaces of which have been fully polymerized, in the cavity, and the hard substance of the tooth, and an acid solution for surface etching of the hard substance of the tooth. The invention further relates to methods for producing a composite inlay.
