Abstract: The invention relates to a clamping device (1) for clamping a cylindrical instrument shank, in particular, a dental instrument, said clamping device comprising a spring-loaded element (2) for holding the instrument shank, a hollow shaft (3) for transmitting a rotational movement, and a plunger, wherein the spring-loaded element (2) is designed as a sleeve with a cylindrical wall, a first opening (6) and a second opening (7); and the wall has cut-outs (8). The spring-loaded element (2), the shaft (3) and the plunger (4) have axes of rotation that are arranged coaxially; the shaft (3) protrudes at least partially into the first opening (6) of the spring-loaded element (2); and the plunger (4) protrudes at least partially into the second opening (7) of the spring-loaded element (2).

Abstract: A dental handpiece and a dental cleaning procedure are disclosed. The dental handpiece includes an inner barrel for rotatably retaining an ultrasonic insert, the inner barrel configured for contacting the ultrasonic insert with a cooling fluid in the inner barrel, a coil unit arranged and disposed to apply an alternating magnetic field to the ultrasonic insert when positioned in the inner barrel, at least one contact retention clip that contacts a drive coil of the contact unit, an outer sheath extending around at least a portion of the coil unit. The dental handpiece includes flow regions permitting steam, chemicals, and heat to flow into the inner barrel and out of the inner barrel during a sterilization technique. The dental cleaning procedure includes operating the dental handpiece and autoclaving the dental handpiece.

Abstract: A dental device is improved in its ability to produce hydroxyl apatite by having a layer of mineral trioxide aggregate (MTA) deposited thereon. A tile of MTA is prepared, heat treated and sintered to produce a micronized tile of MTA that can then be deposited by physical vapor depositions, hot isostatic pressing, molding or other conventional technique.

Abstract: Disclosed is a method for operating a dental diagnostic image generation system of at least two modalities for generating three-dimensional image data by means of X-rays and at least one further beam of a different modality, wherein at least two three-dimensional image data of different modalities are generated and the at least two three-dimensional image data are merged by means of a multimodal registration, it is in particular provided that the image data generation of the at least two three-dimensional image data at an object to be imaged is carried out with markers which overlap during the at least two irradiations of different modalities, that the image data generation of at least one modality is carried out with a capture area limited in accordance with the markers, and that the at least two three-dimensional image data is spatially associated by means of multimodal registration on the basis of the markers captured in the three-dimensional image data.

Abstract: Described herein is a dental composition containing a polymerizable compound having at least one optionally derivatized β-hydroxy urethane unit. The polymerizable compound having at least one optionally derivatized β-hydroxy urethane unit is obtained without use of organo-metal catalysts and isocyanates and by a reaction between an at least one component A having at least one cyclic carbonate group with an at least one component B having at least one of primary amine functional group and secondary amine functional group. The present disclosure relates to use of the polymerizable compound having at least one optionally derivatized β-hydroxy urethane unit for the preparation of a dental composition, in particular a dental composite, a glass ionomer, a dental cement, a dental sealant, and a dental adhesive.
