Provided are methods for making shaped fluoropolymer by additive processing using a polymerizable binder. Also are 3D printable compositions for making shaped fluoropolymer articles and articles comprising a shaped fluoropolymer.

Additive processing of fluoropolymers

The invention relates to a composition that includes a polyolefin, hollow glass microspheres, a polar semicrystalline thermoplastic additive, and at least one of an impact modifier or a compatibilizer. Articles made from the composition, a method of making such an article by melt processing the composition, and the use of the composition are also disclosed.

Polyolefin composition comprising hollow glass microspheres

The invention relates to deformable, curable or film-forming support materials which contain diagnostically useful additives for locus- and substance-specific intraoral diagnostics, and processes for the preparation of images for intraoral locus- and substance-specific diagnostic purposes, in which diagnostically useful additives are applied to deformable, curable or film-forming support materials containing no diagnostically useful additives, in such a quantity that a diagnostic signal can be observed, the diagnostic result being obtained without a cultivation step.

Support materials and imaging method for intraoral diagnostic purposes

The invention relates to urethane prepolymers, obtainable by reaction of:

Radically curable urethane prepolymers and their use in dental materials

Fine-grained powders or powder mixtures can be used to provide for spray cleaning of supragingival tooth surfaces. The abrasion of the tooth surface by the spraying of powder does not exceed 0.15 mmin relation to a tooth surface of 10 mmduring a spray period lasting 2 minutes at a pressure of 4 bars and a distance of no more than 2.5 mm between the tooth surface and nozzle of the spray jet.

Tooth cleaning powders and methods of use thereof

The invention relates to elastomer materials based on N-alkylaziridino compounds with a base component which contains the aziridino compounds and with a catalyst component which contains at least one acid-acting compound, both components being mixed before use, characterized in that, as acid-acting compound of the catalyst component, one or more boric acid complexes are used which can be obtained by reaction of boric acid and/or a boric acid derivative with at least one OH-functional compound, the OH functions being able to be present wholly or partly protected, and this reaction being carried out either as an upstream reaction between boric acid and/or a boric acid derivative and at least one such OH-functional compound or during or after the preparation of the catalyst component or by mixing the catalyst component with the base component which then contains at least one OH-functional compound. The elastomer materials are preferably used as dental impression materials, bite-registration materials and doubling materials.

Two-constituent elastomer materials based on alkyl aziridine comprising a catalyst constituent that contains a boric acid complex

The invention relates to fillers for plastics formulations based on polyurethane and the use thereof.

Filler for plastic formulations based on polyurethane

The invention relates to the use of fine powders or powder mixtures for the preparation of an agent for powder-jet cleansing of dental root surfaces, wherein the powders or powder mixtures provide a density of no more than 2.0 g/cm and/or a mean particle size of no more than 45 &mgr;m.

Subgingival treatment by powder jet

The invention relates to two-component preparations comprising components (I) and (II), wherein at least one component comprises epoxy compounds and the preparations cure by cationic polymerization, initiated by Lewis and/or Br&ouml;nsted acids, after mixing of the two components, the preparations comprising the Lewis and/or Br&ouml;nsted acids in the form of precursor compounds which are suitable for the formation of Lewis and/or Br&ouml;nsted acids.

Two-component preparations containing epoxy compounds

The invention relates to modified plastics characterized in that they contain adhesion-reducing substances in such a quantity that the adhesion of microorganisms to their surface is lower by at least 50% than for non-modified plastics, and in that they contain biocidal substances in such a quantity that at least 60% of the microorganisms remaining are destroyed within 24 hours.

Self-defining plastics and the use thereof in dentistry and dental technology

Dental composites are provided on the basis of customary polymerizable monomers, initiators, fillers and other auxiliaries, which additionally contain the plaque-inhibiting addition of salts of acid-functional polymers having mono- or polyvalent cations.

Plaque-inhibiting composites

The invention relates to fluoride-releasing, polymerizable dental composite aterials having good mechanical stability, containing:

Fluoride-releasing composite materials
