Abstract
A method and apparatus for producing dental restorations for teeth that need to be restored. In the process, a first set of data points is retrieved from a tooth or an image of the tooth to be restored. The tooth is prepared by the dentist and a second set of data points is retrieved from the tooth or an image of the tooth. The second set of points is compared to the first set of points to obtain a third set of points. The dental restoration is milled from dental material based on the image resulting from the third set of data points.
Claims26
A method for producing a three-dimensional body comprising:
- scanning a tooth to obtain a first set of data;
- preparing the scanned tooth;
- scanning the prepared tooth to obtain a second set of data;
- calculating the difference between the first set of data and the second set of data to obtain a third set of data;
- producing a three-dimensional body from the third set of data.
A method for producing a three-dimensional body comprising:
- scanning a first tooth to obtain a first set of data;
- preparing a second tooth;
- scanning the prepared tooth to obtain a second set of data;
- calculating the difference between the first set of data and the second set of data to obtain a third set of data;
- producing a three-dimensional body from the third set of data.
A restoration prepared by the method comprising:
- scanning a tooth to obtain a first set of data;
- preparing the scanned tooth;
- scanning the prepared tooth to obtain a second set of data;
- calculating the difference between the first set of data and the second set of data to obtain a third set of data;
- producing the restoration from the third set of data.
A restoration prepared by the method comprising:
- scanning a first tooth to obtain a first set of data;
- preparing a second tooth;
- scanning the prepared tooth to obtain a second set of data;
- calculating the difference between the first set of data and the second set of data to obtain a third set of data;
- producing the restoration from the third set of data.
An apparatus for manufacturing three-dimensional bodies comprising:
- at least one scanner for scanning one or more teeth;
- a computer for receiving data and calculating an error function between a first set and a second set of data to provide a third set of data.
