Abstract

The present invention relates to a process for generating a CAM dataset, having the steps of providing (S 201 ) a digital CAD dataset for a dental prosthesis having first reference data for a first spatial reference geometry; providing (S 202 ) a digital CAM dataset having second reference data for a second spatial reference geometry; and integrating (S 203 ) the CAD dataset in the CAM dataset by aligning the first spatial reference geometry of the CAD dataset with the second spatial reference geometry of the CAM dataset.

Claims (25)

1. A process for generating a CAM dataset (CAM), comprising:

providing (S 201 ) a digital CAD dataset (CAD) for a dental prosthesis ( 103 ) having first reference data for a first spatial reference geometry ( 105 - 1 );

providing (S 202 ) a digital CAM dataset (CAM) having second reference data for a second spatial reference geometry ( 105 - 2 );

integrating (S 203 ) the CAD dataset (CAD) into the CAM dataset (CAM) by aligning the first spatial reference geometry ( 105 - 1 ) of the CAD dataset (CAD) with the second spatial reference geometry ( 105 - 2 ) of the CAM dataset (CAM);

wherein the first and/or second spatial reference geometry ( 105 - 1 , 105 - 2 ) indicates a spatial axis and/or a reference cross; and

milling the dental prosthesis ( 103 ).

2. The process as claimed in claim 1 ,

wherein the CAM dataset (CAM) comprises data for a blank ( 101 ) for producing the dental prosthesis ( 103 ).

3. The process as claimed in claim 2 ,

wherein the data for the blank ( 101 ) render a circular disc.

4. The process as claimed in claim 2 ,

wherein the data for the blank ( 101 ) render an inhomogeneous structure of the blank ( 101 ) for generating a gum impression.

5. The process as claimed in claim 4 ,

wherein the inhomogeneous structure is formed by a waveform.

6. The process as claimed in claim 1 ,

wherein the spatial axis is oriented perpendicularly to a surface of a blank ( 101 ).

7. The process as claimed in claim 1 ,

wherein the CAM dataset (CAM) can be selected from a plurality of previously stored CAM datasets.

8. The process as claimed in in claim 1 ,

wherein the dental prosthesis ( 103 ) is generated automatically on the basis of the CAM-dataset (CAM).

9. The process as claimed in in claim 1 ,

wherein the CAM dataset (CAM) is converted into milling data for milling the dental prosthesis.

10. The process as claimed in claim 9 ,

wherein the dental prosthesis ( 103 ) is milled on the basis of the milling data by a milling device ( 107 ).

11. A computer program product comprising program code which is stored on a non-transitory machine-readable medium, the machine-readable medium comprising computer instructions executable by a processor, which computer instructions cause the processor to perform the process according to claim 1 .
