Solution Overview
Problem
Current augmented reality technologies are primarily used for entertainment purposes and lack applications in medical or dental fields, such as simulating orthodontic treatments or modifying facial structures for treatment planning and patient visualization.
Innovation Solution
A system and method utilizing computer vision and augmented reality to superimpose computer-generated images of orthodontic appliances, dental restorations, and craniofacial modifications onto real-time video feeds, allowing for simulation of orthodontic and restorative treatments, including virtual rendering of treatment outcomes and comparison of before-and-after scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality technology is used for entertainment purposes only, then device complexity is reduced and ease of operation is improved, but adaptability to medical and dental applications is limited
Solution Approach 1:
The system applies augmented reality technology across multiple domains including entertainment, medical, and dental applications. The same AR platform is used to display virtual appliances on teeth for orthodontic treatment planning, demonstrating multi-functionality that resolves the contradiction between adaptability and complexity.
Solution Approach 2:
The system segments the application into distinct modules: facial image capture, treatment plan data processing, virtual appliance rendering, and augmented display. This segmentation allows the complex medical/dental functionality to be implemented through manageable components, reducing the perceived device complexity while maintaining high adaptability.
2Measurement precision
If comprehensive treatment planning and visualization features are implemented, then measurement precision and information quality are improved, but loss of time for processing and initial setup increases
Solution Approach 1:
The system performs preliminary actions by capturing facial images and processing treatment plan data before the patient visit. Treatment plans are prepared in advance with virtual appliance configurations, so that during the actual patient interaction, the system can quickly display accurate visualizations without time-consuming processing, thus reducing time loss while maintaining measurement precision.
Solution Approach 2:
The system creates digital copies of the patient's facial features and teeth from treatment plan data. These copies are then manipulated and visualized with virtual appliances, allowing precise measurement and visualization without requiring physical models or repeated measurements, thereby maintaining precision while reducing time consumption.
3Loss of information
If virtual rendering of treatment outcomes is provided, then information quality and patient understanding are improved, but device complexity and computational requirements increase
Solution Approach 1:
The system uses an intermediary computing platform that processes treatment plan data and generates virtual renderings of treatment outcomes. This intermediary layer handles the complex computational requirements separately from the patient-facing interface, allowing high-quality information delivery without increasing the complexity of the devices used during patient consultations.
Solution Approach 2:
The system creates visual copies of treatment outcomes by rendering virtual appliances on digital models of the patient's teeth. These visual copies provide comprehensive information about treatment results without requiring physical prototypes or complex display devices, maintaining information quality while managing device complexity.

AI summary
A system and method for simulating orthodontic treatment using augmented reality. An electronic image of a user's face is received from a digital camera, and a region of interest in the image is identified where the region includes the user's teeth. Virtual orthodontic appliances are placed on the user's teeth in the image, and the user's image with the virtual orthodontic appliances is displayed on an electronic display device. The method occurs in real-time to provide the user with the augmented image simulating treatment when or shortly after the image of the user is received. The system and method can display a 3D representation of the user's face augmented with the virtual appliances. The user's augmented image or 3D representation can also be supplemented for display with an image or model of the user's facial anatomy such as an x-ray or a cone beam computed tomography image.
