Block-Based Denture Tooth Arrangement for Occlusion and Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for designing dentures are time-consuming and can undesirably affect previous tooth transformations when designing denture teeth one at a time, lacking efficient enforcement of esthetic and functional design rules.
Innovation Solution
Grouping denture teeth into blocks and applying design rules enforced by a computer to maintain functional or esthetic rules during design, ensuring a desired dental setup is achieved quickly and correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If denture teeth are designed one at a time, then detailed customization is possible, but the design process becomes time-consuming and previous transformations may be undesirably affected
Solution Approach 1:
The patent divides the complete set of denture teeth into multiple blocks, where each block contains a subset of teeth. This segmentation allows the design software to enforce transformation rules at the block level rather than requiring individual tooth-by-tooth design, significantly reducing design time while maintaining precision through automated rule enforcement.
Solution Approach 2:
The patent implements preliminary action by pre-defining transformation rules and constraints for blocks of teeth before the actual design process begins. These rules are automatically enforced during tooth transformations, preventing undesirable effects on previous transformations and eliminating the need for manual adjustment of each tooth individually.
2Reliability
If design rules are strictly enforced digitally, then functional and esthetic rules are maintained, but user transformations may be prevented or overridden
Solution Approach 1:
The patent implements dynamic design rule enforcement where rules are applied selectively based on the specific transformation being performed. The system evaluates whether a transformation violates a rule and only prevents or overrides the transformation when necessary, allowing maximum user flexibility while maintaining reliability for critical functional and esthetic requirements.
Solution Approach 2:
The patent applies different levels of rule enforcement to different blocks of teeth based on their specific functional and esthetic requirements. Critical blocks with strict functional requirements receive more stringent rule enforcement, while other blocks allow greater user flexibility, optimizing both reliability and ease of operation for different regions of the denture.

AI summary
A method for digitally designing a denture for a patient, where the denture includes a plurality of denture teeth, where designing the denture includes transforming denture teeth of the denture, wherein the method includes obtaining a 3D scan of the upper jaw and lower jaw of the patient; obtaining a digital 3D arrangement of the denture teeth, where the denture teeth are pre-set in occlusion; digitally arranging the 3D scan of the upper jaw and lower jaw relative to the 3D arrangement of the denture teeth; digitally grouping the denture teeth in four groups, the four groups includes an upper anterior group, a lower anterior group, a left posterior group, and a right posterior group; and digitally arranging the upper anterior group first, the left and right posterior groups second and the lower anterior group third.
