Teeth Position Monitoring via 3D Model Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients often fail to attend regular check-ups post-orthodontic treatment, leading to relapse of teeth position, which requires additional extensive treatment, and existing monitoring methods are inconvenient and stressful for both patients and orthodontists.
Innovation Solution
A method involving the creation of a target teeth model post-treatment, with subsequent updated models taken at intervals using personal devices like smartphones or 3D scanners, comparing these models to detect relapse and inform patients or dental professionals of the need for consultation, optimizing visit scheduling and treatment efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If patients attend regular in-person check-ups at the orthodontist's office, then teeth position can be monitored accurately, but patient convenience deteriorates and orthodontist workload increases
Solution Approach 1:
The system enables patients to perform self-monitoring of their teeth position using portable scanning devices and mobile applications. Patients can independently capture 3D images of their teeth, process them through the application, and compare results with their target model without requiring orthodontist intervention for each check-up, thus improving convenience while maintaining monitoring capability
Solution Approach 2:
A mobile application acts as an intermediary between the patient's teeth and the orthodontist. The application processes 3D scans, compares them with the target model, and provides automated feedback, eliminating the need for direct in-person visits while ensuring accurate monitoring through systematic image analysis and comparison algorithms
2Reliability
If patients attend regular in-person check-ups, then relapse can be detected early, but time loss for travel and appointments increases
Solution Approach 1:
The system enables periodic monitoring at the patient's convenience rather than requiring periodic travel to the orthodontist's office. Patients can perform scans and comparisons on their own schedule, reducing time loss while maintaining reliable relapse detection through regular automated assessments
Solution Approach 2:
Patients independently perform monitoring scans and receive automated comparisons with their target model, eliminating travel time and appointment scheduling while ensuring reliable relapse detection through consistent periodic assessment at home
3Measurement precision
If traditional in-person monitoring is used, then comprehensive teeth assessment is possible, but stress on both patient and orthodontist increases
Solution Approach 1:
Patients perform self-assessment using portable scanning devices and mobile applications, eliminating the stress of frequent in-person visits while maintaining comprehensive teeth evaluation through systematic 3D imaging and automated comparison with target models
Solution Approach 2:
The mobile application serves as an intermediary that performs comprehensive automated assessment, reducing stress on both patients by eliminating travel and orthodontists by automating the monitoring process while maintaining thorough evaluation through multi-angle 3D scanning and algorithmic comparison

AI summary
A method for monitoring the position of a patient's teeth includes the following steps: a) modeling a target position of the teeth in the form of a target model; b) after a time interval, modeling an updated position of the teeth in the form of an updated model; and c) comparing the target and updated models. The updated model is created by the patient himself or by one of his relations.
