Abstract
The invention relates to the examination of a dental prosthesis, wherein the dental prosthesis is examined with finite element methods. Furthermore, the invention relates to the automated manufacture of a dental prosthesis, wherein the shape of a remaining tooth area is directly determined on the basis of the remaining tooth area itself. Furthermore, the invention relates to a method, wherein manufacturing data (milling data) which have been created with a system for calculating manufacturing data (system for calculating milling data) are optionally forwarded to one or another manufacturing machine (milling machine) at different locations.
Claims12
Method, comprising:
- examining an initial dental prosthesis data record representing an initial dental prosthesis using finite element methods, after the initial dental prosthesis has been broken,
- automatically determining a change to the initial dental prosthesis data record according to results of the examination,
- producing a new dental prosthesis data record, wherein the new dental prosthesis data record automatically reflects the change to the initial dental prosthesis data record,
- examining the new dental prosthesis data record using finite element methods, and
- producing a new dental prosthesis corresponding to the new dental prosthesis data record.
