Dental Motion Prediction for Interference-Free Treatment Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental procedures often result in unwanted interference between teeth due to changes in jaw motion following dentition adjustments, which are not adequately accounted for in existing treatment plans, leading to patient discomfort and multiple office visits.
Innovation Solution
A motion adjustment prediction system that analyzes a dental treatment plan by scanning and assessing dentition motion, predicting potential jaw motion adjustments, and modifying the plan to accommodate these changes, thereby preventing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dentition adjustment is performed to correct tooth alignment or occlusion, then dental function is improved, but jaw motion changes occur that cause interference with opposing teeth
Solution Approach 1:
The system performs preliminary prediction of jaw motion changes before the actual dentition adjustment is made. By analyzing the planned tooth movement and simulating its effect on jaw motion, the system identifies potential interference issues in advance and allows modification of the treatment plan to prevent harmful effects before they occur.
Solution Approach 2:
The system creates a feedback loop by predicting the consequences of dentition adjustment on jaw motion and feeding this information back to the treatment planning stage. This allows the dentist to see the predicted interference and adjust the treatment plan accordingly, transforming a potentially harmful outcome into a controlled, predictable result.
2Device complexity
If traditional dental treatment planning is used without motion prediction, then treatment simplicity is maintained, but patient discomfort and additional visits increase
Solution Approach 1:
The system allows the treatment plan to self-correct by automatically predicting jaw motion changes and identifying potential interference. The software provides built-in analysis and warning capabilities that help the dentist refine the plan without requiring external consultation or additional patient visits, making the system practically self-sufficient.
Solution Approach 2:
By performing motion prediction and interference analysis before treatment execution, the system prevents the need for corrective visits. Potential problems are identified and resolved in the digital planning stage, eliminating the need for physical adjustments and follow-up appointments that would otherwise be required.
3Productivity
If dentition adjustment is made without considering jaw motion changes, then treatment speed is maintained, but interference and patient discomfort occur
Solution Approach 1:
The system replaces physical trial-and-error adjustment methods with computational prediction. Instead of making actual tooth movements and observing their effects, the system uses software simulation to predict jaw motion changes and identify interference before any physical treatment is performed, maintaining efficiency while eliminating harmful effects.
Solution Approach 2:
The motion prediction system acts as an intermediary between the dentition adjustment plan and the actual treatment execution. It translates the planned tooth movement into predicted jaw motion effects and identifies potential interference, serving as a mediator that allows the dentist to optimize the plan without immediate physical consequences.

AI summary
A motion adjustment prediction system is described. A scan of a dentition is performed to generate a digital dental model from which a position and orientation of each tooth in the upper and lower dental arches of the dentition is determined with respect to each other tooth. A dentition motion assessment is performed to capture motion data representing a movement of the dental arches relative to each other. A dental treatment plan with dentition adjustment is determined based on the scan and the dentition motion assessment. The dentition adjustment can include a restoration preparation, such as a crown or a bridge, or can include an orthodontic alignment. A motion adjustment is predicted based on the dentition adjustment, and the dental treatment plan is modified based on the predicted motion adjustment.
