A dental implant includes an insert element of a titanium-based material inserted and soldered into a blind hole in an anchoring element of a ceramic material. An outer surface of the insert element has spacer members to center the insert element in the blind hole, with a uniform circumferential gap space relative to the anchoring element. The insert element is longer than the blind hole, so that a portion of the insert element protrudes outwardly beyond an end face of the anchoring element. The blind hole is partly filled with a glass solder suspension, and the insert element is inserted into the blind hole, whereby an excess amount of the glass solder is displaced out of the gap space onto the end face of the anchoring element and the protruding portion of the insert element. A thermal soldering process secures the insert element into the anchoring element. The protruding portion of the insert element and remaining excess solder is removed to form a planar surface.

The present invention relates to devices having a thermochromic temperature indicator for accommodating, heating and applying dental materials, to corresponding methods of heating dental materials and of recognizing the temperature of the dental materials, and to a corresponding kit.

A glass based fibrous filler having bioactive particles such as hydroxyapatite deposited on a surface of glass fibers. Methods of preparing the fibrous filler are specified. A resin composite containing a polymerizable system reinforced with the fibrous filler, as well as a biomedical restoration based on the cured resin composite are also provided.

A computer-controlled method for forming a composition-controlled product using 3D printing includes disposing two or more liquid reactant compositions in respective two or more reservoirs; and mixing the two or more liquid reactant compositions, which in turn includes controlling by the computer a mass ratio of the mixed two or more liquid reactant compositions. The computer-controlled method further includes scanning, under control of the computer, a mixed liquid reactants nozzle over a substrate; depositing the mixed liquid reactant compositions onto the substrate; and operating, under control of the computer, a light source to polymerize the deposited mixed liquid reactant compositions.

A cosmetic and/or therapeutic treatment of tissue, such as tooth, is disclosed that effects, for instance, whitening and tissue re-building through mineralisation. Further, a method of performing iontophoresis utilizing an aqueous composition of a remineralising agent to achieve mineralisation is disclosed, as well as a kit for performing the mineralization or remineralisation.

A milling blank for producing medical-technical molded parts made from a material produced from at least two components, wherein a first component A comprises a poly(alkyl methacrylate) polymer, and wherein a second component B comprises at least one alkyl acrylate monomere and/or one alkyl methacrylate monomer, in which the poly(alkyl methacrylate) polymer of component A is at least partially soluble, wherein the material comprises a flexibilizer as a further component, wherein the flexibilizer is selected from the group of citric-acid-based, adipic-acid-based, phthalic-acid-based or aliphatic esters.
