摘要： 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.

摘要： A method for optically measuring an object by means of an optical recording apparatus includes a triangulation method. A first shutter means is used to produce a first pattern and to project the first pattern as a first projection beam onto the object to be measured. At least one further shutter means is used to produce a further pattern and to project the further pattern as a further projection beam onto the object to be measured. The first pattern and the further pattern are passed back from the object as observation beams and are recorded by at least one recording means in order to obtain a three-dimensional data record of the object. The projected first pattern and the further pattern are recorded at the same time in at least one triangulation recording using the at least one recording means.

摘要： A method for producing a drill assistance device for a tooth implant includes the process steps of, initially the taking of an x-ray picture of the jaw and the compilation of a corresponding measured data record; then a three-dimensional, optical measurement of the visible surfaces of the jaw and of the teeth and the compilation of a corresponding measured data record. The measured data records from the x-ray picture and the measured data records from the three-dimensional, optical image are correlated with each other. Based on the information that is now available the type and position of the implant relative to the adjacent teeth is planned and a drill template is produced which is attached to the neighboring teeth, thus making the exact drilling of the implant pilot hole possible.
