An additive manufacturing process comprising:

Additive manufacturing process

The present invention relates to an aqueous dental glass ionomer composition for use in the treatment of cavitated carious lesions, which composition comprises a water-soluble, polymerizable polymer comprising acidic groups, which is reactive with the particulate glass in a cement reaction, whereby the polymerizable polymer has a polymer backbone and pendant groups having one or more polymerizable carbon-carbon double bonds. The dental glass ionomer composition is used as a permanent direct restoration.

Direct dental filling compositions

The present invention relates to a dental composition comprising a dental filler containing a structural filler and silanated glass flakes. Furthermore, the present invention relates to the use of silanated glass flakes for preparing a dental composition.

Dental composition comprising a dental filler containing a structural filler and silanated glass flakes

Described herein is a dental material applicator system comprising a segmented capsule and handpiece. The capsule separately holds a powder and a liquid such that upon activation in the handpiece by an operator, the powder and liquid are mixed into a paste. The operator then triggers the handpiece so that the mixed paste is extruded.

Dental material delivery system

A user interface unit for an automatic door drive comprises a display unit for outputting output information and a control element arrangement for capturing input information. The user interface unit, together with the door drive, is mountable in a first spatial position and in a second spatial position on a door that is drivable by the door drive. The control element arrangement comprises a first control element and a second control element, wherein the first control element is arranged in the first spatial position of the user interface unit on the same spatial side of the control element arrangement as the second control element in the second spatial position. The display unit is designed to display the displayed output information in the same spatial orientation in both the first spatial position and the second spatial position of the user interface unit. In addition, the user interface unit is designed to capture the same input information in the first spatial position with the first control element as with the second control element in the second spatial position.

User interface unit

The present invention relates to a dental composition comprising a specific polymerizable compound and a polymerization initiator system. Furthermore, the present invention relates to the specific polymerizable compound as such and its use in a dental composition. The specific polymerizable compound of the present invention has an N-allyl (meth)acrylamide group, which nitrogen atom is substituted with an alkyl or alkenyl group optionally substituted by a group selected from a hydroxyl group, a Calkoxy group, a tertiary amino group and a carboxyl group, wherein 1 to 8 carbon atoms in the main chain of the alkyl or alkenyl group may independently from each other be replaced by a heteroatom selected from an oxygen atom and a sulfur atom.
