The present invention relates in particular to the storage of dental material in a device (') and the application of the dental material () from such a device (&#x2032;), and a method for treating dental material (). In order to provide a solution that allows the simple and practical handling of a dental material () in the sense of storage, application and/or treatment thereof, inter alia, a device (&#x2032;) for storage and application () comprising a cavity () for storage of the dental material () and a wall () surrounding the cavity () is proposed, wherein the wall () in at least a first temperature range is impermeable to radiation of at least a first wavelength or a first wavelength range in the range of 100 nm to 500 nm, wherein the wall () comprises at least one area that at least in a second temperature range is permeable to radiation of at least a second wavelength or a second wavelength range in the range of 600 nm to 50,000 nm.

Device for storage and application and method

Described is a milling blank for producing an indirect dental restoration, composed of resin or a resin-based composite, containing water in an amount of at least 25% of the water sorption W. Described is further a method for producing such a milling blank or a moulded part produced therefrom for use as an indirect dental restoration, a use of the water sorption method, a kit for producing indirect dental restorations and a method for indirect dental restoration.

Milling blank for producing an indirect dental restoration, corresponding uses and methods

A dental milling blank for the production of permanent indirect restorations in the CAD/CAM process, characterized in that it has a water sorption WSP of less than/equal to 18 &#x3bc;g/mm, measured according to ISO 4049 and an E modulus E greater than/equal to 13 GPa, measured according to the ADA specification No. 27 and a quotient Q of WSP/E of less than 1.35 &#x3bc;g/(GPa&#xd7;mm) and consists of the polymerization product of a radically curable dental composition, which comprises

Dental milling blank for the production of permanent indirect restorations and computer-aided process for producing the permanent indirect restorations

The present invention relates to novel free-radically curable dental compositions, comprising chain-like and/or cyclic and/or cage-type polysiloxanes substituted by free-radically polymerizable groups and having at least 3 silicon atoms and/or mixed forms thereof, disiloxanes substituted by free-radically polymerizable groups, optionally one, two, three or more free-radically curable dental monomers having no silicon atom, fillers, initiators and/or catalysts for free-radical polymerization, and also further customary additives, to the cured dental products formed from the dental compositions of the invention, and to the respective use thereof as dental material, especially as flowable filling composites (called 'flow materials'), core buildup materials and luting cements. The invention further relates to a method for producing the dental compositions and to a process for producing a respective dental product. Additionally claimed are inventive kits containing the novel free-radically curable dental compositions.

Free radically curable dental compositions

The present invention relates to the use of free-radically curable compositions, comprising chain-like and/or cyclic and/or cage-type polysiloxanes substituted by free-radically polymerizable groups and having at least 3 silicon atoms and/or mixed forms thereof, disiloxanes substituted by free-radically polymerizable groups, optionally one, two, three or more free-radically curable monomers having no silicon atom, fillers, initiators and/or catalysts for free-radical polymerization, and also further customary additives, in additive manufacturing methods, preferably in stereolithography (SL) and digital light processing (DLP). The present invention further relates to the use of the cured free-radically curable compositions, preferably for production of dental products.

Use of free radically curable compositions in additive manufacturing methods

The present invention relates to dental polymerizable composite materials (curable dental compositions) comprising one or more plasticizers comprising a tricyclic structural element, to dental materials (polymers), obtainable by curing from the dental polymerizable composite materials comprising one or more plasticizers comprising a tricyclic structural element, to processes for producing a dental material and to dental curable composite materials for use in a therapeutic method in the production of a dental material.

Dental composite materials comprising tricyclic plasticizers

Novel polymerizable compounds comprising a polyalicyclic structure element and certain functional groups, mixtures comprising one or a plurality of these compounds and corresponding curable blends and products as well as their respective use as dental material or for the preparation of a dental material are described. A method for preparing these compounds or mixtures and a method for preparing a product, preferably a product suitable for dentistry, are also described.

Polymerizable compounds comprising a polyalicylic structure element

A curable dental composition comprising a monomer with a polyalicyclic structure element that can be used for filling and/or sealing of a root canal is described. Also described is a composition useful as a dental material and a method for preparing such a composition. New polymerizable monomers comprising at least one polyalicyclic structure element and certain ethylenic structure elements, which are particularly suitable for use in a dental composition, and the use of the new monomers in a dental composition are also described.
