The present invention provides methods and separation media for separating analytes of interest via free flow electrophoresis (FFE) using volatile buffer systems. The separation media provided herein allow a convenient separation of the analytes by electrophoresis, and offer the additional advantage that the buffer compounds and the solvent can be easily and residue-free removed after the electrophoretic separation step. Furthermore, methods for mass spectrometric analysis of analytes comprising an FFE method and kits for carrying out FFE separations with volatile buffer systems are also provided. Preferably, the volatile buffer system is TRIS acetate.

A surface mapping and generating device which has devices for the process and/or cost optimization, in particular raw material recovery devices, an automatic control of the intensity of a used laser light, devices for carrying out a calibrating procedure by evaluating overlap errors at matching points, devices for archiving especially three-dimensional data of the jaw and/or for modeling the bite position of the upper and the lower jaws, devices for the optimized preparation of at least one dental stump for the production and placement of a dental prosthesis thereon and/or devices for taking into consideration the bite position of the upper and lower jaws. It can be provided that the devices for the process and/or cost optimization are designed to ensure that two half frames showing different positions or views are evaluated, whereby preferably a pulsed laser for exposure purposes is included and/or that an image recording device, in particular a CCD chip, is arranged so as to ensure that lines, taking into account the Scheimpflug angle, are located perpendicular to the direction of travel of a measuring table. Methods according to the present invention use such devices and function correspondingly. In addition, the invention also makes available a patient data archiving system which comprises a chip card and/or decentralized data storage systems especially for dental data.
摘要:
Device for holding a model of a dental prosthesis part, such as an abutment, including a first portion in which the mode of the dental prosthesis part can be modeled on and a second portion which allows a definite position identification of the holder, as well as a device for scanning objects, such as a jaw model and/or dental models and/or saw tooth model sections, comprising a holder in which an above-mentioned device with a definite position orientation can be held and scanned. Also provided is a method of generating a digital model of a dental prosthesis part, such as an abutment, including the steps of evaluating the scan data for detecting at least one part of the shape of the dental prosthesis part and evaluation of the scan data to detect at least the position of the holder, a data carrier with instructions to carry out such a method as well as a method of manufacturing a dental prosthesis part.

摘要:
The invention relates to a method for manufacturing dental prostheses, wherein from a raw material area, such as a blank, a dental prosthesis is manufactured (milled out) at a manufacturing position, such as a milling position, the manufacturing position of one or more dental prostheses being determined on the basis of one or more predetermined criteria. Furthermore, the invention relates to a method for checking a worked raw material area and/or a manufacturing arrangement for a raw material area, wherein it is checked whether one or more manufacturing shapes can still be manufactured from a number of predetermined manufacturing shapes. Moreover, the invention relates to a method for manufacturing a dental prosthesis, wherein from a raw material area a dental prosthesis is manufactured, wherein a raw material is selected from a plurality of raw material areas on the basis of one or more predetermined criteria. Moreover, the invention relates to a corresponding computer, a computer program, and a machine-readable medium.

A method and apparatus for producing data for making dental prostheses, wherein the data can be produced on the basis of a model (2) which comprises individual segments (3a, 3b, 3c, . . . ), such as representing a tooth, a preparation, a gingival area, a tooth gap or a small group of teeth, from different directions in space, and a storing device for storing the shape data obtained thereby, and—second shape data (12) of only the one segment (3a, 3b, 3c, . . . ), only part of the segment (3a, 3b, 3c, . . . ) being scanned, and the segment (3a, 3b, 3c, . . . ) being arranged in a fixed orientation relative to a reference, and b) a comparing device for comparing the first and second shape data (1, 12) to determine the orientation of the first shape data (1) relative to the reference.
摘要:
In order to provide a decorative coating (9) which exhibits improved temperature resistance and strength on glass and glass-ceramic and which also has no strength-reducing effect on the substrate (3), or at least no longer has any substantially strength-reducing effect on the substrate, the invention envisions a process for producing glass or glass-ceramic articles having a decorative layer in which at least one decorative pigment (13) is mixed with a sol-gel binder (11), and the pigment mixed with the sol-gel binder is cured on the glass or glass-ceramic substrate of the article by annealing, to form a decorative layer having a porous ceramiclike structure.
