The sliding panel has means for mounting a dental model and stands on projections disposed on its underside. A 3D scan of a tooth model is provided by creating a first image of the object to be scanned at a precisely defined locked position, moving the sliding panel to at least one further precisely defined locked position and creating another image at each such position, and creating a 3D data set by evaluating the images produced at least two different, precisely defined positions.

Abstract: The invention relates to a method for the production of a tooth prosthetic piece (21), in particular, a skeleton, using a blank (3) for machining in a material ablating 3D-forming process, said blank being made from a material not yet having the final hardness, comprising a terminal hardening of the formed piece (2) produced during the forming process to give a formed piece (2?), with the final hardness, whereby the 3D forming process is divided into coarse machining process for the blank (3) and a precise finishing process for the formed piece (2?) with the final hardness, in order to give the final form of the tooth prosthesis piece (21). The invention further relates to a mount or mounting set for carrying out the method in said particular fashion, comprising connectors for mounting the blank and suited to the shrinkage factor of the fixed formed piece.

Abstract: The invention relates to a blank for producing dental shaped parts, comprising a blank body (1) made of tooth restoration material, from which the shaped part can be machined using a tool (11, 12, 13, 14, 15) for removing material. The aim of the invention is to enable a reliable verification or recognition of the tool fitting or of the type and state of wear of the used tool of a machine tool for the blank. To this end, the blank has at least one gauge (4, 5), whose dimensions are such that the tool present for the machining can be identified by the gauge on the basis of its outer contour. The invention also relates to a method for producing dental shaped parts with a blank body made of tooth restoration material, from which the entire shaped part can be machined in a machining device by a tool for removing material.

Abstract: A carrier for at least one fastening element (4) to be fabricated having an attachment area whereby the carrier is provided with a holding piece (3) for attachment in a receiving part of a finishing machine and whereby the carrier includes a carrier piece (2) for the fastening element (4) and the carrier piece (2) is embedded at least partially in the carrier piece (2) in a manner so that the attachment area (4b) of the fastening element (4) can be fabricated. A method for producing a fastening element (4) to be finished and to be attached to an individual surface whereby the contour of the attachment area is defined with the aid of data of the surface onto which the fastening element (4) is to be attached and whereby a pre-shaped, not yet individualized fastening element (4) is formed by removal of material to produce the specific contour.

Abstract: A device for operation by means of a hand-held dental instrument, in which a function of the instrument is triggered by a user by means of a triggering device, in which the device comprises a delay circuit which causes a time delay between triggering and activation of the function. In a method of operating a hand-held dental instrument, in which a function of the instrument is triggered by a user by means of a triggering device, triggering actuates a delay circuit which activates the desired function following a time delay.

Abstract: A blank and method for the production of dental shaped bodies in machining equipment having at least two tools located in the machining chamber of the machining equipment, including a corpus of tooth restoration material, from which the shaped body can be carved by means of at least one of at least two tools by material removal. The blank exhibits at least two gages, each of which is in the form of a recess, the geometry of which is such that the tool selected for the cutting operation can be recognized by means of at least one of the gages by reference to its outer contour, the at least two gages being disposed on the blank in such a way that they can be simultaneously engaged by the at least tools when the blank is clamped in the machining equipment for carving purposes.
