Abstract: A device for protecting electrode holders in CVD reactors includes an electrode suitable for accommodating a filament rod on an electrode holder which includes an electrically conductive material and is installed in a recess of a bottom plate, wherein an intermediate space between an electrode holder and a bottom plate is sealed by means of a sealing material, and the sealing material is protected by a protective body which is made up of one or more parts and is arranged in a ring-like manner around the electrodes, and the height of the protective body increases at least in sections in the direction of the electrode holder.

Abstract: A root canal instrument includes a twisted strip having a titanium-nickel alloy or a plastics material. The strip has a cross-section having three exterior surfaces or four exterior surfaces. A coating is disposed on at least one exterior surface, the coating includes abrasive particles. A method of making the root canal instrument includes making a basic plate having a thickness of less than one millimeter, coating the basic plate with a coating having the abrasive particles; dividing the basic plate into longitudinally extended strips, twisting the strip to form a root canal drill bit having a cutting edge with abrasive particles disposed on the cutting edge.

Abstract: 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 damage 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.

Abstract: The invention relates to an obturation device (1) for blocking an apical foramen of a root canal of a tooth by means of an obturation plugging mass. The obturation device (1) has a carrier (5), wherein the obturation plugging mass is arranged in slidingly displaceable manner, and has an applicator (6), by means of which the obturation plug (4) comprising obturation plugging mass is applied in the apical foramen. The applicator (6) has a housing (7) with a pushing mechanism (8), which mechanism is arranged to be brought into engagement with the carrier (5) and pushes the obturation plugging mass from the carrier (5) into the apical foramen.

Abstract: The invention relates to a retraction thread, especially a dental retraction thread for use in dentistry, that is distinguished by the fact that it has yarns produced by an air vortex process.

Abstract: The present invention relates to an articulating paper for use in dentistry, which comprises a support layer that is provided on at least one side with at least one colour layer comprising a colouring pigment, wherein there is present, on at least one colour layer, a layer that has at least one adhesion promoter for the colouring pigment(s) of the colour layer(s).

Abstract: The invention relates to a delivery system for fluid substances, which comprises a plunger-type syringe in the form of a cartridge having at least one injectate chamber, which injectate chamber is provided with an injection plunger, and an attachment mounted on the cartridge at its delivery-side end, characterised in that the attachment is mounted on the cartridge by means of a releasable snap closure.

Abstract: The present invention relates to an articulating aid for use in dentistry, which is characterised in that it has, on at least one side of a support layer, a plurality of differently coloured colour layers comprising colouring pigments and at least one adhesion promoter for at least one colouring pigment of at least one of the coloured colour layers

Abstract: The invention relates to a dispenser (1) for viscous media (3), having a dispenser reservoir (2), an expelling mechanism and a dispenser delivery tube (5). The dispenser reservoir (2) has a nozzle (4) and the expelling mechanism exerts a pressure on the viscous medium (3) in the dispenser reservoir (2). Under that pressure, the viscous medium (3) is expelled by way of an opening (6) of the nozzle (4) of the dispenser reservoir (2) and through the dispenser delivery tube (5). The dispenser delivery tube (5) is removable from the dispenser reservoir (2) and has a seat (7) for a stop check valve (8), which is arranged between the nozzle (4), having the opening (6), and the dispenser delivery tube (5).

Abstract: The invention relates to a root canal instrument (1) which has a core (7) of a flexible elastic material having shape memory. The core furthermore has a coating with abrasive particles. For the purpose, the core itself is made from a nickel-titanium alloy or from a plastics material, preferably a carbon-fibre-reinforced plastics material, the flexibility of the coating being matched to the flexibility of the core.

Abstract: The present invention relates to a dental insertion element for use in the oral cavity, which insertion element is characterised in that it has a cross-sectional area having a non-circular periphery.

Abstract: The present invention is concerned with a gutta-percha point for filling a tooth root canal system, which is characterised in that in that it has at least one portion having a cross-sectional area with a non-circular circumference and in that the surface of the gutta-percha point has a different roughness in different sections.

Abstract: Compression cap for tooth stumps and method of drying a tooth stump The present invention relates to a compression cap (1) for tooth stumps (5) and to a method of drying a tooth stump (5). The compression cap (1) for tooth stumps (5) has a hollow space (7) for receiving an absorbent foam mass (8) surrounding a tooth stump (5). The hollow space (7) has an opening (9) at one end for receiving the reagents (10, 11) for the foam mass (8) and for receiving the tooth stump (5) and is surrounded by walls whose wall thickness (d) is reduced in the direction towards the opening (9). The rim (14) at the opening has a spatial profile (15) of such a kind that the rim (14) at the opening constitutes a seal (16) when the compression cap (1 ) is in the state pressed against the interdental papilla (17) of a tooth stump (5) in the region of the gingival pocket (18) for the sulcus (19).
