Abstract: A method for manufacturing a dental implant apparatus that comprises an implant and an implant support that can be placed next to one another by contact surfaces and that have contours providing security against rotation that are integrally molded on in one piece. The implant and an implant support have mutually matching contours that prevent a rotation of the implant and the implant support when placed next to one another. A tool system for carrying out the described methods and a dental implant apparatus that is manufactured in a corresponding manner are further disclosed. A contact surface of the implant is ground using a first grinding gauge that has a grinding surface having the shape of the contact surface of the implant attachment but not having the shape of the contour providing security against rotation of the implant.

Abstract: A method and device for producing a tear line on a planar workpiece by material removal by means of a pulsed laser, wherein machining cycles are preceded by a method step for generating and storing a reference signal curve which is formed by reference signals, causing the pulse amplitude of the laser pulses, via removal locations along the contour of the tear line. The achievement of a respective predetermined percentage of the reference signal or of an absolute distance from the reference signal by a measurement signal is used as the space-resolved deactivation criterion for each removal location, which measurement signal is obtained from a transmitted part of the pulse amplitude at the respective removal location.

The invention further relates to a tool system for carrying out such a method and furthermore to a dental implant apparatus that is manufactured in a corresponding manner.

Abstract: Process for producing a line of weakness in a cover element comprising at least one slit. This slit is produced through a plurality of machining cycles in which a pulsed laser beam is guided in each instance over the cover element along an imaginary line so that the energy of the laser pulses is introduced into the cover element. The slits are produced in two segments. More energy is introduced over the machining cycles in the first, comparatively short segments than in the second, comparatively long segments. The residual wall below the slits decreases with each machining cycle until the first residual wall segment thickness in the first segment is so small that energy portions transmit through the first residual wall segment and are detected by a sensor arrangement arranged downstream. Accordingly, the first residual wall segment thickness is detected, and inferences can be drawn from this about the second residual wall segment thickness.

Abstract: A dental implant comprises an implant screw (1) with an external thread (5), an implant abutment (3) and a tightening screw (4) which can be screwed into the implant screw (1) and by which the implant abutment (3) is connectable or connected with the implant screw (1), wherein the implant screw (1) rests against a contact surface (14, 15) of the implant abutment (3) with a contact surface (10, 11). To improve such dental implant, the implant screw (1) and the implant abutment (3) are made of a ceramic material at least in the region of their contact surfaces (10, 11; 14, 15). The contact surface (14, 15) of the implant screw (1) and the contact surface (14, 15) of the implant abutment (3) are ground in against each other.

Abstract: The present invention relates to the production of a series of holes in a layer of material, in particular to the production of a target rupture line in a first layer of an airbag cover. The radiation of a plasma that forms during the production of each hole is detected from the surface that is being machined. From the signal pattern derived, the time of the beginning of the signal and the time of the appearance of a falling edge that meets a predetermined edge criterion are detected and stored. The point in time at which the falling edge appears is a switching criterion for switching off the laser. The difference between the two points in time stored for each hole constitutes a quality criterion for the respective hole.
