Dental adhesives and their uses, for instance an adhesive containing at least one first component A and at least one second component B, characterized in that said at least one first component A comprises a methyl methacrylate, a copolymer of methyl methacrylate dissolved in excess methyl methacrylate, at least one polyfunctional (meth)acrylate and a peroxide-based free-radical initiator, wherein said copolymer of methyl methacrylate is present in an amount of 30-50 parts by weight dissolved in a solution of 65-85 parts by weight of monomeric methyl methacrylate and 3-15 parts by weight of the polyfunctional (meth)acrylate, especially the triethylene glycol dimethacrylate (TEGDMA), mixed with a solution of 0.5 to 3 parts by weight of said peroxide-based free-radical initiator, especially dibenzoyl peroxide, in 70-90 parts by weight of monomeric methyl methacrylate, and said at least one second component B comprises methyl methacrylate and a tertiary amine.

Two-component adhesive for bonding artificial teeth to a denture base

Molded member made of form-stabilized material, comprising at least one first component and one second component, characterized in that the second component has a different pigmentation than the first component and the second component is disposed inside the first element, forming a boundary surface, in such a way that the boundary surface represents a spatially curved surface.

Molded member made of form-stabilized material and method for the manufacture thereof

A composite material with a porous inorganic-nonmetallic matrix and a second material, and a process for its production, are characterized in that the porous inorganic-nonmetallic matrix has a bending strength &#x2267;40 MPa as measured according to ISO 6 872; the second material is an organic material which at least partly fills the pores of the porous matrix; and the composite material has a modulus of elasticity, E, &#x2267;25 GPa as measured according to ISO 10 477.
