Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manufacturing dental prostheses are complex, generate dust leading to contamination, require skilled manual operation, and increase manufacturing time and cost.
Innovation Solution
The method involves photographing a patient's mouth with a dental cone beam CT, converting the data into a CAD file, designing the prosthesis using CAD and occlusion simulation software, and manufacturing it using a machine with alternating roughing and finishing tools or rapid prototyping technology, eliminating manual operation and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional manual manufacturing methods are used, then manufacturing flexibility is maintained, but manufacturing time and cost increase
Solution Approach 1:
The patent replaces manual mechanical operations with a computer-controlled manufacturing system. The manufacturing machine receives design data from a computer, automatically processes the dental prosthesis through programmed operations, and eliminates manual labor in the manufacturing process, thereby reducing manufacturing time and cost while maintaining precision
Solution Approach 2:
The patent uses digital copying of the patient's mouth anatomy through scanning or imaging to create a virtual 3D model. This digital copy is then used to generate precise manufacturing data, eliminating the need for physical impression models and subsequent manual processing steps, thereby streamlining the manufacturing process
2Manufacturing precision
If manual operation is used in manufacturing, then operational flexibility is maintained, but manufacturing precision decreases
Solution Approach 1:
The patent replaces manual mechanical operations with computer-controlled precision machining. The manufacturing machine executes programmed operations with high precision, ensuring accurate reproduction of the prosthesis geometry while reducing the skill level required from the operator
Solution Approach 2:
The patent incorporates feedback mechanisms where the manufacturing machine can detect and adjust for deviations from the digital design model. This ensures that the final prosthesis matches the intended precision requirements, with the system automatically compensating for operational variations
3Object-affected harmful factors
If traditional manufacturing processes are used, then manufacturing versatility is maintained, but contamination increases
Solution Approach 1:
The patent replaces manual manual handling and processing with automated machine operations. The manufacturing machine processes the prosthesis material through controlled programmed operations, minimizing exposure to contaminants and reducing the need for manual intervention that could introduce contamination
Solution Approach 2:
The patent employs controlled manufacturing environments that minimize exposure to contaminants. The automated processing system operates in a controlled setting that prevents contamination from external sources, maintaining material purity throughout the manufacturing process
