Abstract: The process for producing tooth replacement parts is characterized in that curable tooth replacement material is introduced into a first mold of part of the human dentition, a positive model produced from a second mold is pressed into this material and the tooth replacement material remaining after the pressing-in is allowed to cure to form the tooth replacement part(s).

Abstract: A subject-matter of the invention is an impression material with at least one compound with at least two alkenyl groups as component (a), at least one compound with at least one chelating group as component (b), at least one organohydropolysiloxane as component (c), at least one hydrosilylation catalyst as component (d) and at least one compound with a chelatable metal atom as component (e), the chelating group of the component (b) exhibiting no reactive groups which can react with the component (c) and/or the component (d). The invention achieves a long storage stability.

Abstract: The invention relates to a polymerizable material for the production of a dental material for building up stumps, having the following characteristics: —the material comprises at least one polymerizable monomer, oligomer, and/or pre-polymer, —the total filler content of the material is 50 to 85% by weight, —the material comprises 5 to 25% by weight nano-filler, having a mean particle size d5o of 300 nm or less, wherein at least 50% by weight of said nano-filler has a particle size of 200 nm or less, —the material comprises 35 to 75% by weight micro-filler, having a mean particle size d50 of 0.3 to 10 ?m, —the ability to grind the cured material for building up stumps deviates from the ability to grind human dentin by 15% at the most. The invention further relates to a kit comprising at least two components for the production of such a polymerizable material.

Abstract: The invention provides an infiltrant for dental application that comprises crosslinking monomers. In accordance with the invention the infiltrant has a penetration coefficient PC>50 cm/s, and comprises 0.05%-20% by weight of acid-group-containing monomers.

Abstract: The subject matter of the invention is a kit for fixing a dental restoration material on a tooth substance, which material contains the following components: a. an electron donor compound; b. a first adhesive component which contains an oxidation agent as constituent of a polymerization initiator system and a polymerizable acid; c. a second adhesive component which contains a reduction agent as constituent of a polymerization initiator system and a polymerizable monomer, oligomer, or prepolymer, which does not contain any acid groups.
