Abstract: A dental blank for the manufacture of a dental restoration. The dental blank comprises a dental block and an insert with an opening facing toward an outer surface of the dental blank. The insert comprises at least one positioning element for the positioning of an abutment.

Abstract: A hollow-cylindrical device (1) having first and second openings (2, 3) for continuous production of a dental composite block. A curable composite material (4) and a temperature control unit (5) are provided. The composite material (4) is introduced into the device (1) through the first opening. The composite material (4) is cured by energy from the temperature control unit (5). An energy input occurs across a defined length of the substantially hollow-cylindrical device (1) and/or for a defined period of time. The composite material (4) is subsequently guided through the first opening (2) of the device (1). The composite material (4) is discharged from the second opening (3). In a first region along a portion of the length of the device, the device is either provided with an insulation or the flow-through device has a heat conductivity of 0.05 to 12 W/(m×K).

Abstract: A dental restoration, a method for the production of a dental restoration and a kit. The dental restoration comprises an outer component, in particular a shell, and an inner component, in particular a core. The inner component and the outer component contain composite material. The outer component is mountable or mounted on the inner component. The inner component is designed for attachment onto a tooth preparation, in particular a tooth stump.

Abstract: The invention relates to a tooth veneer element (1), in particular for a human tooth (5), in particular for covering a facial cervical surface (6) of the tooth (5.1). The tooth veneer element (1) is designed to only partially cover a facial surface of a tooth crown (5.2) of the tooth (5.1). The invention also relates to a kit with a plurality of tooth veneer elements for veneering tooth surfaces, wherein the tooth veneer elements especially have different shapes and/or sizes and/or colours and/or degrees of translucency. The invention further relates to a method for applying such a tooth veneer element (1) to a tooth, wherein the tooth veneer element (1) is applied to the tooth in such a way that a facial surface of a tooth crown (5.2) of the tooth (5.1) is only partially covered, wherein in particular a facial cervical surface (6) of the tooth (5.1) is covered substantially completely.

Abstract: The present invention pertains to the technical field of dental restorations, especially dental posts. One aspect of the present invention is a radio-opaque coated dental post. The post essentially consists of a core embedded in a thermoplastic or duroplastic material. The core is further coated with yet another resin with at least one radio-opaque additive. X-ray visibility especially at the outer margin of the post is significantly improved.

Abstract: The invention concerns a dental filling material with dual hardening mechanism, wherein i) a first hardening mechanism is based on a photocuring reaction, preferably a radical reaction, and ii) a second hardening mechanism is dependent on H2O as a reactant, especially as a ligand. Preferably, the second hardening mechanism is a gypsum-type reaction. Owing to the expansion of the composition an excellent marginal seal can be achieved, while the first hardening mechanism allows for a rapid cure on demand.
