20080259411 | Scanner Arrangement - A scanner arrangement which is designed to scan only one part at a time in order to permit scanning results of a model or die-shaped unit consisting of two or more parts which can be joined together or taken apart and which can have different longitudinal inclination axes and/or configurations. The scanner has, for each respective part, a support member adjustable with different inclinations in order to adapt the respective part's longitudinal inclination axis to a longitudinal displacement movement effected by the scanner's contour-sensing member relative to the supported part at the same time as the contour-sensing member is set at an angle with respect to a rotation axis for the part. The support member is designed to movably support the respective part and a unit with a grid surface and to be adjustably arranged with the same inclination as the part in question and a selected height position. After contour sensing and removal of the respective part, the scanner is designed to rescan a portion which is located on the grid surface and which is continuous with the respective part's position in space. The grid pattern is designed to indicate unique positions • for the data thus scanned. The scanner or a computer unit connected to it transforms, by means of an algorithm, the positions corresponding to the positions which are present in the model or. the die-shaped unit and which, in subsequent signal or data generation, form the basis for the dental bridge structure. By means of the invention, it is readily possible to use one-part scanners to scan dental objects with several parts, without the scanner functions having to be reconfigured. The handling principles for model and tool production can be retained, likewise the handling in the computer environment in the manufacture of the dental product. Costs can be kept low, and precision requirements and speed of production can be maintained. | 10-23-2008 |
