Dental Prosthesis Internal Surface Machining for Precise Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental prosthesis design and manufacturing processes face challenges in achieving precise dimensional accuracy, particularly for internal surfaces of crowns, which is critical for fitting and preventing infection, and often require complex coordination between dental clinics and laboratories.
Innovation Solution
A system that utilizes a dental service center equipped with material removal machines to manufacture precise internal surfaces of dental prostheses, such as crowns, based on 3D numerical models, while dental laboratories focus on external surfaces, enabling shared manufacturing and design responsibilities according to predetermined criteria, with communication via electronic networks for efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If dental laboratories manufacture both internal and external surfaces of prostheses, then manufacturing coordination is simplified, but dimensional accuracy of internal surfaces deteriorates
Solution Approach 1:
The patent divides the prosthesis manufacturing process into two specialized segments: dental service centers that manufacture internal surfaces requiring high precision, and dental laboratories that manufacture external surfaces. This segmentation allows each facility to specialize in specific manufacturing tasks, with service centers using material removal machines to achieve superior dimensional accuracy on internal surfaces while laboratories handle aesthetic external surfaces.
2Productivity
If dental clinics send all manufacturing tasks to dental laboratories, then workflow is simplified, but production efficiency and cost-effectiveness deteriorate
Solution Approach 1:
The patent introduces a dental service center as an intermediary entity between dental clinics and dental laboratories. The service center receives digital impressions and manufacturing instructions from clinics, produces internal surfaces using automated material removal machines, and coordinates with laboratories for external surface completion. This intermediary role optimizes the workflow by distributing tasks to the most appropriate facility, improving overall production efficiency and cost-effectiveness.
3Reliability
If traditional manufacturing methods are used for internal surfaces, then manufacturing process is simpler, but fitting precision and infection prevention deteriorate
Solution Approach 1:
The patent replaces traditional manual manufacturing methods for internal surfaces with automated material removal machines that use computer-controlled mechanisms. These machines precisely remove material from dental blanks based on digital models, achieving superior dimensional accuracy and surface finish that prevent infection while ensuring precise fitting. The automated system eliminates human error and variability inherent in manual processes.
