Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual post-processing is used to insert aesthetic surface structures, then aesthetic quality can be achieved, but the process becomes time-consuming and skill-dependent
Solution Approach 1:
The patent uses digital copying by creating a virtual model of the aesthetic surface structure from existing three-dimensional data, then inserting this digital copy into the dental prosthesis plan. This eliminates the need for manual physical copying while preserving aesthetic quality.
Solution Approach 2:
The patent replaces the manual mechanical process of inserting aesthetic surface structures with an automated computer-based system. The virtual tool automatically inserts and adapts the surface structures based on digital parameters, eliminating manual intervention while maintaining aesthetic quality.
2Adaptability or versatility
If manual post-processing is used for aesthetic surface structures, then individual adaptation is possible, but the process requires great experience and skill
Solution Approach 1:
The patent enables individual adaptation by allowing modification of specific parameters of the aesthetic surface structure through the virtual tool. Users can adjust digital parameters such as position, orientation, shape, and size without requiring manual skill, making the system both adaptable and easy to use.
3Productivity
If automated virtual post-processing is implemented, then productivity increases, but individual adaptation capability must be maintained
Solution Approach 1:
The patent implements a dynamic system where the virtual tool can automatically insert aesthetic surface structures while also allowing real-time parameter adjustment. This enables both high productivity through automation and individual adaptation through flexible parameter modification within the same automated workflow.

AI summary
The invention relates to a method for the virtual post-processing of a first virtual three-dimensional dental model (14) of a dental prosthesis (28), said model having been created during the planning of the prosthesis (28). The first virtual dental model (14) is processed virtually after the planning stage in an additional method step (18, 31) by adapting at least one three-dimensional aesthetic surface structure (17) already in existence to the first dental model (14) by means of a virtual tool (10) with the aid of a computer (4) and a display device (6) and by subsequently inserting said structure into the first dental model (14). The aesthetic surface structure (17) has a predetermined form, size and/or a predetermined impression depth (41), and a tooth surface (19) of the dental model (14) is at least partially replaced by the adapted aesthetic surface structure (15, 17).
