3D Digital Tooth Model Replacement Without Reworking Occlusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dental technology, replacing three-dimensional digital tooth models requires significant rework as existing methods fail to efficiently transfer adjustments made to the patient's intraoral anatomical state to new models, leading to inefficiencies for practitioners.
Innovation Solution
A method for replacing first three-dimensional digital tooth models with second models by identifying and adjusting dental key structures using identifiers, ensuring they match the form, position, and orientation of the original models while maintaining other characteristics, thereby enabling efficient switching between different sets of templates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If three-dimensional digital tooth models are replaced by new models, then new template characteristics can be utilized, but the arranging and adjusting process must be completely repeated from scratch
Solution Approach 1:
The patent applies preliminary action by pre-arranging and pre-adjusting the new three-dimensional digital tooth models to match the patient's intraoral anatomical state before replacement. This includes pre-positioning models at correct tooth positions, pre-orienting them with proper tooth orientations, and pre-adjusting their shapes to fit the patient's anatomy, so that when replacement occurs, minimal additional work is needed
Solution Approach 2:
The patent uses copying by transferring the arrangement and adjustment information from the original tooth models to the new models. The system copies positional data, orientational data, and shape adjustment parameters from the first set of models to the second set, allowing the new models to inherit the optimized configuration without requiring complete re-adjustment
2Adaptability or versatility
If three-dimensional digital tooth models are replaced by new models, then different template options become available, but all adjustments must be redone
Solution Approach 1:
The system copies adjustment data from original models to replacement models, transferring positional information, orientational information, and shape adjustment parameters. This allows practitioners to switch between different template options while retaining the beneficial adjustments already made, significantly improving productivity
Solution Approach 2:
The patent implements universality by creating a system where adjustment information can be universally applied across different sets of three-dimensional digital tooth models. The arrangement and adjustment data becomes a universal template that can be transferred to any new model set, making the system adaptable to various template options without requiring separate adjustment processes for each
3Manufacturing precision
If dental key structures are matched between first and second models, then precise alignment is achieved, but model characteristics may be compromised
Solution Approach 1:
The patent applies local quality by making adjustments only to specific local regions of the new models - namely the dental key structures such as cusps, incisal edges, and contact points - while leaving the rest of the model characteristics unchanged. This ensures precise alignment of critical functional elements while preserving the unique features and aesthetics of the new template designs
Solution Approach 2:
The system segments the tooth model into distinct functional components (dental key structures) and aesthetic components. The matching process is applied selectively only to the segmented key structures that require precise alignment for function, while the segmented aesthetic portions retain their original model characteristics without modification

AI summary
Disclosed is a method for replacing first three-dimensional digital tooth models by second three-dimensional digital tooth models. The method comprises receiving a three-dimensional digital anatomic model of an oral anatomic structure of a patient and the first three-dimensional digital tooth models arranged with respect to the three-dimensional digital anatomic model at tooth positions with tooth orientations. The first three-dimensional digital tooth models comprise first identifiers identifying the dental key structures. First three-dimensional digital tooth models are selected for a replacement. The selected first three-dimensional digital tooth models are replaced by the second three-dimensional digital tooth models.
