The invention relates to a hardenable dental resin composition provided as a kit of parts comprising a powder part and a liquid part, the powder part comprising acid-reactive glass filler A, non acid-reactive nanocluster filler B, the liquid part comprising polymerizable components with an acidic moiety, polymerizable components without an acidic moiety, the hardenable dental composition further comprising a dual-cure initiator system the components of which being distributed between the powder part and the liquid part, wherein the dual-cure initiator system comprises sensitizing agent(s), oxidizing component(s), (thio)barbituric acid component(s) and transition metal component(s). The composition can be used as a self-adhesive dental resin filling material, self-adhesive dental resin core build up material, self-adhesive dental resin cement material, self-adhesive fissure sealing material, a self-adhesive dental root channel material.

Self-adhesive dental resin composition and use thereof

The invention relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit of parts comprising a Powder Part P and a Liquid Part L, Powder Part P comprising: acid-reactive inorganic filler, Liquid Part L comprising: water, complexing agent, polyacid, either the Powder Part P or the Liquid Part L or the Powder Part P and the Liquid Part L comprising non-aggregated nano-sized particles based on silica or alumina, the composition obtained by combining the components of Powder Part P and Liquid Part L before hardening comprising the components in the following amounts: non-aggregated nano-sized particles: from 0.1 to 15 wt.-%, acid-reactive filler in an amount from 50 to 75 wt.-%, polyacid: 7 to 20 wt.-%, complexing agent: 0.5 to 3 wt.-%, water: 5 to 18 wt.-%, wt.-% with respect to the weight of the whole composition.

Kit of parts for producing a glass ionomer cement, process of production and use thereof

The application relates to a kit of parts for preparing a glass ionomer composition for dental use, the kit comprising a Paste A and a Paste B, Paste A comprising water, acid-reactive inorganic filler C, non acid-reactive filler A, Paste B comprising water, polyacid, complexing agent, non acid-reactive filler B, the mean particle size of non acid-reactive filler B being larger than the mean particle size of non acid-reactive filler A, the water content of the composition obtained when mixing Paste A and Paste B being below 20 wt.-%. The application also relates to a device for storing such a kit of parts and the use of the kit of parts and/or the device for preparing a dental cement, dental filling material, dental core build up material or dental root channel filling material.

The invention relates to a kit of parts for preparing a glass ionomer cement, the kit comprising a Part A and a Part B, Part A being a powder and comprising an acid-reactive filler in an amount above about 60 wt. %, the acid-reactive filler having a mean particle size in the range of 3.5 to 10 &#x3bc;m, an non acid-reactive filler in an amount above about 1 wt. %, the non acid-reactive filler having a mean particle size in the range of 1.0 to 3.5 &#x3bc;m, Part A not comprising a polyacid in an amount above about 1 wt. %, wt. % with respect to the weight of Part A, Part B being a liquid and comprising a polyacid in an amount above about 30 wt. %, water, a complexing agent, wt. % with respect to the weight of Part B. The invention also relates to a process of producing a hardenable or hardening composition and use thereof in the dental field.

Glass ionomer cement, process of production and use thereof

Dental fiberpost

The present invention features ionomer compositions containing nanofillers that provide the composition with desirable aesthetic properties (e.g., optical translucency). The compositions can be used in a variety of dental and orthodontic applications, for example, as adhesives, cements, restoratives, coatings and sealants.
