Abstract: The present invention relates to a process for producing dental milling blanks, wherein inorganic filler powders are in a first step surface-coated with a silane and wherein in a second step a polymerizable composition is adsorbed on the silanized surface. Subsequent compression and polymerization affords a homogeneous milling blank having very good mechanical properties.

Abstract: The invention concerns a storage and mixing device for producing a dental preparation comprising two, three or more mixing components, wherein the storage and mixing device has an individual chamber or two or more chambers which are separated from each other in a storage condition and which contain the mixing components, and an actuator moveable from a storage position for maintaining the storage condition of the storage and mixing device into a reaction position for bringing the mixing components together. In accordance with the invention it is proposed that a first and a second mixing component and optionally one or more further mixing components are already accommodated in the individual chamber or a first chamber of the plurality of chambers when the actuator is still in the storage position.

Abstract: A method for infiltration and/or sealing of hard tooth tissue and for detection of caries in the infiltrated region or under the seal by means of fluorescence, is described. The method includes applying a composition comprising a filler system consisting of or comprising inorganic filler particles surface-modified by means of organic structural elements, wherein the organic structural elements can be reacted with an organic binder system to form covalent bonds, wherein the filler particles of the composition have an average particle size in the range between 1 nm and 150 nm, and an organic binder system comprising one or more polymerizable monomers, wherein the filler system is dispersed in the organic binder system (b). The infiltrated or sealed surface of the hard tooth tissue is then irradiated with excitation radiation which causes emission of fluorescence radiation. The fluorescence radiation data is recorded and used to detect curies.
