Abstract
The invention relates to a method for the optical three-dimensional measurement of a dental object, wherein a first region of the dental object is measured using a first optical three-dimensional measurement method, wherein the first optical three-dimensional measurement method is based on a triangulation method and on a fringe projection method. According to the invention, a powdering occurs at least on the first region, wherein first image data are generated. Using a less precise, second optical three-dimensional measurement method, a second region of the dental object is subsequently measured without previous powdering, wherein second image data are generated. Afterwards, the first image data are combined with the second image data to form an overlapping three-dimensional exposure.
