  • Patent number: 8883876
    Abstract: The subject matter of the invention is a radically polymerizable dental material comprising at least two components. A first component of the dental material contains the salt of a CH-acidic compound, and an additional component contains an acid with acidity greater than that of the CH-acidic compound of the first component. Both components contain radically polymerizable monomers. When the two components are mixed, the acid of the second component converts the salt of the CH-acidic compound of the first component into a CH-acidic molecule, and the CH-acidic molecule triggers the radical polymerization of the monomers. In addition to the advantages of CH-acidic compounds in dental materials on the basis of a reactive resin, the invention achieves long-term storage stability as a result of an increase in the proportion of the reactive resin matrix in polymerizable dental materials.

  • Patent number: 8853338
    Abstract: Presently described are curable dental compositions comprising a polymerizable ionic liquid. The polymerizable ionic liquid comprises one or more ethylenically unsaturated (e.g. free-radically polymerizable) groups. Various embodiments of curable dental compositions are described. In some embodiments, the polymerizable ionic liquid is a monofunctional polymerizable ionic liquid comprising an ethylenically unsaturated group. In other embodiments, the polymerizable ionic liquid is a multifunctional polymerizable ionic liquid comprising at least two ethylenically unsaturated groups. The curable dental compositions describe herein can be utilized as dental primers, dental adhesives, dental sealants, and dental composites. In many embodiments, the curable dental compositions further comprise an initiator such as a photoinitiator.

  • Patent number: 8853297
    Abstract: The present invention refers to a method of infiltrating enamel for the prevention and/or treatment of carious lesions comprising (a) exposing an enamel area to a conditioner comprising hydrochloric acid; (b) exposing the conditioned enamel area to an infiltrant; and (c) curing the infiltrant. The present invention further refers to a kit for carrying out the method of infiltrating enamel, which comprises a conditioner comprising hydrochloric acid and an infiltrant comprising at least one low viscous dental resin. Alternatively, the kit comprises ready-to-use means for carrying out the method of infiltrating enamel, e.g. application strips with delivery pads soaked with conditioner or infiltrant. The present invention also refers to a method for identifying an infiltrant by calculation of the penetration coefficient, and to an infiltrant identified by the method having a penetration coefficient of >50 cm/s or comprising a low viscous light curing resin having a penetration coefficient of >50 cm/s.

  • Publication number: 20140295376
    Abstract: Provided are opaque materials exhibiting a good adhesive strength and a good color tone reproduction comparable with natural dental crowns as well as having a good operability. In addition, the opaque materials may exhibit a stain-resistance property in rebuilding-up a dental composition on the opaque materials in a cured form with a metal instrument. Further, the opaque materials may exhibit a good color tone reproduction comparable with natural dental crowns even if a dental membrane is thinly formed from the opaque metals. The dental membrane is formed from a first opaque layer and a second opaque layer, wherein the first opaque layer contains a filler of indefinite-shape particles and the second opaque layer contains a filler of spherical-shape particles, and wherein the first opaque layer is formed on a metal base and the second opaque layer is formed on the first opaque layer.
