摘要： A method of manufacturing a dental post according to the present invention comprises the steps of: (i) overjacketing extrusion of at least one thermoplastic material over at least one filament or yarn, such that the thermoplastic material cross-sectionally enwraps the at least one filament or yarn; (ii) solidifying the extruded product of step (i); (iii) equipping the solidified extruded product of step (ii) with a surface texture, such that the thermoplastic wrapping is not modified in a way as to expose or dam-age the at least one filament or yarn.The invention allows for more flexibility in the manufacturing of dental posts, especially in generating surface textures of such dental posts.

摘要： A retaining device (1) for at least two containers (5, 5′) comprises a basic body (11) with an accommodating opening (2), in which the containers (5, 5′) can be fixed in a defined removal sequence. This retaining device (1) is a constituent part of a container arrangement having at least two containers (5, 5′), and accommodates the containers (5, 5′). The container arrangement is characterized by such an arrangement of the containers (5, 5′) in the retaining device (1) that the containers can be removed from the retaining device (1) in a predeterminable sequence.

摘要： 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.
