Orthodontic Aligner Cavities for Predicting Un-Erupted Tooth Shape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional orthodontic aligners struggle to accurately predict the shape of un-erupted or partially erupted teeth, leading to generic space buffers that may not look natural and can interfere with tooth eruption or cause discomfort.
Innovation Solution
The use of 3D descriptors and automated agents to identify representative tooth shapes based on anatomical identifiers, allowing for the creation of virtual 3D tooth models and customized orthodontic appliances that accommodate un-erupted teeth without interfering with their eruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional generic tooth shape space buffers are used, then the orthodontic aligner can be manufactured with simple techniques, but the space buffer may not look natural and can interfere with tooth eruption or cause discomfort
Solution Approach 1:
The patent applies preliminary action by predicting the future shape and size of un-erupted teeth before orthodontic treatment begins. Virtual 3D models of the unerupted teeth are created in advance, allowing the aligner to be designed with cavities that will perfectly accommodate the teeth when they erupt, rather than using generic shapes that may cause interference or discomfort.
Solution Approach 2:
The patent uses parameter changes by varying the size, shape, and position of cavities in the orthodontic aligner based on predicted tooth characteristics. The system adjusts multiple parameters including tooth dimensions, crown shape, root position, and cavity geometry to create a customized fit for each patient's specific unerupted teeth, transitioning from generic to highly specific parameters.
2Ease of manufacture
If conventional generic tooth shape space buffers are used, then the manufacturing process is simplified, but the space buffer may cause discomfort to the patient
Solution Approach 1:
The system performs preliminary prediction of tooth eruption characteristics before the orthodontic treatment begins. By creating virtual 3D models of the unerupted teeth in advance, the system can design cavities that will perfectly accommodate the teeth when they erupt, preventing discomfort and interference that would result from using generic space buffers.
Solution Approach 2:
The patent adjusts multiple parameters including cavity size, shape, position, and orientation based on predicted tooth characteristics. This customization ensures that the orthodontic aligner accommodates each patient's specific unerupted teeth without causing discomfort, eliminating the harmful effects associated with generic one-size-fits-all approaches.
3Device complexity
If conventional generic tooth shape space buffers are used, then the design process is simplified, but the space buffer may interrupt tooth eruption
Solution Approach 1:
The patent applies preliminary action by predicting the future shape, size, and position of un-erupted teeth before orthodontic treatment begins. Virtual 3D models are created in advance, allowing the aligner to be designed with cavities that will perfectly accommodate the teeth when they erupt, preventing interruption of the eruption process.
Solution Approach 2:
The system uses parameter changes by varying cavity dimensions, shape, and position based on predicted tooth characteristics. This customization ensures that the orthodontic aligner provides adequate space and proper guidance for tooth eruption, preventing the interference that occurs with generic space buffers.
