PROCEDURE AND ARRANGEMENT FOR DENTAL RESTORATION |
摘要 |
The present invention relates to a method and to an arrangement for preparing a tooth restoration model for the restoration of a full tooth or part of a tooth. The arrangement functions to determine measurement values, by measuring a first surface (31) of an object (2) to be measured. The object (2) may be a tooth, the copy of a tooth, an impression of a tooth, or a prepared part of a tooth. The arrangement also functions to move the object so as to enable the object to be scanned at a plurality of points thereon, for which points a distance is calculated by optical triangulation. By compilation with data relating to movement of the object there are obtained measurement values which constitute a data description of the outer surface (31, 51) of the object or a part of this outer surface. The arrangement includes a computer unit which processes the measurement values and generates the aforesaid model therefrom in the form of a data description of its surfaces. |
