  • Publication number: 20060019219
    Abstract: A method for determining the position and orientation of the axis of a dental implant disposed directly in the mouth of a patient wherein measurement data is obtained by measurement of the clinical situation of the implant in the patient's mouth, a first shape to be measured is applied to the implant, the shape is formed in such a manner that a conclusion can be made about the position and orientation of a connection shape of the implant, and the position and orientation of the first shape is analyzed through a suitable method. Furthermore, the relative position and orientation of the area between the axis of the dental implant and the axis of the measurement is defined through the specific position of the first shape. The position and orientation of the connection shape and of the implant itself is determined through the first shape.

  • Publication number: 20060008774
    Abstract: A method of producing a dental prosthetic item from a blank involving generation of a machining schedule for machining equipment includes the following steps: the blank exhibits at least two regions having different properties, the regions are displayed separately together with a reproduction of the prosthetic item, the position of the reproduction of the prosthetic item in the blank can be changed relatively to the regions by input means, and the machining schedule is adjusted or generated taking into consideration the position of the reproduction of the prosthetic item. In this way the position, within the blank, of the prosthetic item to be carved from the blank can be checked and adjusted.

  • Publication number: 20060008776
    Abstract: A method and apparatus for designing the surface of a dental prosthetic item consisting of three-dimensional data, wherein three-dimensional data of a surface (30) of an electronically stored tooth (11) are used at least as part of the surface of the dental prosthetic item to be fabricated, to which end the surface of the tooth (30) is first of all determined as to size and then placed against an electronically stored prosthetic item or the region of a preparation site (1;21) existing as three-dimensional data. The position of the digital tooth surface (30) over the dental prosthetic item or in the preparation site (1; 21) can be set with regard to at least one spatial axis and/or at least one direction of rotation.

  • Patent number: 6155777
    Abstract: The removal of cooling air from the diffuser part of a radial end stage of a compressor of a gas turbine is provided. Compressed air is removed via a cooling air discharge (10) from a radial compressor stage, which comprises a rotor disk (2) and a bladed diffuser (20). The removal of cooling air may be brought about such that the cooling air is removed on one side through openings (6) on the housing side (20.1) of the diffuser (20) and is fed through cooling air channels (10) to the parts in contact with hot gas, including the outer wall of the bifurcated tube (17). The compressed air is guided to the diffuser outside (20.2) through cooling air holes (19) in the diffuser blade (3).
