Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If naked-eye observation and silicone rubber guide plates are used for tooth preparation design, then the process can be completed with simple tools, but measurement precision and reliability deteriorate due to erroneous determination
Solution Approach 1:
The patent uses digital scanning to create a virtual copy of the real tooth model, then compares it with a standard prepared tooth model to obtain precise restoration data. This digital copying and comparison eliminates the need for physical silicone rubber guide plates while maintaining high measurement precision through automated data processing.
2Reliability
If naked-eye observation is used to determine tooth preparation quality, then the process is simple, but reliability deteriorates due to subjective errors
Solution Approach 1:
The patent replaces the mechanical naked-eye observation system with an automated digital image processing system. The computer automatically compares the real tooth model with the standard model and generates restoration data, eliminating subjective human errors and significantly improving determination reliability through objective algorithmic analysis.
3Productivity
If silicone rubber guide plates are prepared for tooth design, then physical reference is available, but loss of time and increased cost occur due to additional preparation steps
Solution Approach 1:
The patent uses digital copies of tooth models stored in the system to provide reference for preparation design, eliminating the need to physically prepare silicone rubber guide plates each time. This digital referencing approach maintains productivity by providing immediate access to standard models while reducing material consumption and preparation time.

AI summary
A method, apparatus and device for determining tooth restoration data, and a storage medium are provided. A real tooth model of a target object and a standard prepared tooth model corresponding to the real tooth model are acquired. The real tooth model includes a tooth to be prepared, the standard prepared tooth model includes a standard prepared body corresponding to the tooth to be prepared, and the standard prepared body is a standard prepared tooth for wearing a prosthesis. The tooth to be prepared in the real tooth model is compared with the standard prepared body in the standard prepared tooth model, so as to obtain data to be restored of the tooth to be prepared. The data to be restored is data to be ground that corresponds to the restoration of the tooth to be prepared to the standard prepared body.
