Preset Denture Milling Blocks for Direct Jaw-Base Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing dentures require time-consuming and costly individual adjustments after creating the jaw base, involving wax setup and bite registration, which prolongs the dental treatment process.
Innovation Solution
A milling block system with pre-set, standardized arrangements of artificially shaped teeth for the upper and lower jaws, allowing for direct milling of the denture base to fit the patient's jaw shape, eliminating the need for further adjustments and reducing the number of steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual adjustments are made after creating the jaw base using wax setup and bite registration, then optimal fit and occlusion are achieved, but the treatment process becomes time-consuming and expensive
Solution Approach 1:
The patent applies preliminary action by pre-setting the teeth in the milling block according to standardized occlusion principles before the denture base is milled. This eliminates the need for subsequent wax setup and bite registration steps, as the teeth are already positioned correctly for optimal occlusion. The jaw base is then milled directly to fit the patient's oral cavity, achieving both precision and time efficiency.
2Manufacturing precision
If individual adjustments are made after creating the jaw base, then optimal fit and occlusion are achieved, but the manufacturing cost increases
Solution Approach 1:
The invention performs the tooth positioning action in advance by incorporating pre-set teeth into the milling block design. This eliminates the need for expensive wax setup materials, bite registration materials, and multiple adjustment visits. The standardized tooth arrangements are pre-programmed into the CAD system, allowing direct milling of the final denture base without additional manufacturing steps.
3Adaptability or versatility
If multiple adjustment steps are performed, then individual patient adaptation is optimized, but the number of processing steps increases
Solution Approach 1:
The patent eliminates multiple adjustment steps by pre-configuring the teeth in standardized occlusion patterns within the milling block. The CAD/CAM system uses pre-programmed tooth arrangements that are universally applicable. Only one customization step remains - milling the jaw base to fit the patient's specific oral cavity geometry - thereby maintaining individual adaptation while dramatically simplifying the overall process.
4Measurement precision
If separate bite registration and articulator steps are performed, then accurate jaw relations are determined, but the manufacturing process becomes more complex
Solution Approach 1:
The invention extracts and eliminates the separate bite registration and articulator steps from the traditional denture manufacturing process. By using pre-set teeth in standardized occlusion positions within the milling block, the system determines jaw relations directly during the CAD design phase. The jaw base is milled to fit the patient's oral cavity with the teeth already in their final positions, removing the need for intermediate measurement and transfer steps.
