Solution Overview
Problem
Dental practitioners face challenges in accurately determining patient-specific information for orthodontic and prosthetic procedures due to limited and flawed anatomical insights, leading to poor outcomes and high costs, as existing devices are cumbersome, costly, and prone to errors.
Innovation Solution
A method and system using consumer-grade depth-sensing devices like smartphones to capture facial and dental data, employing AI/ML models to determine reference points, planes, and ratios for precise dental treatment planning, considering both static and dynamic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If practitioners use traditional mechanical, electronic, or radiographic devices to collect facial and dental information, then measurement precision may be improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces complex mechanical, electronic, and radiographic devices with a smartphone-based system using depth-sensing cameras and AI/ML algorithms. The depth-sensing camera captures facial geometry data, and machine learning models automatically identify anatomical landmarks and calculate measurements, eliminating the need for cumbersome traditional equipment while maintaining measurement precision.
Solution Approach 2:
The system creates a digital 3D model (copy) of the patient's facial and dental anatomy through depth-sensing imaging. This digital replica allows practitioners to perform measurements and analysis on the model rather than requiring complex physical devices to interact with the patient's actual anatomy, simplifying the operational process.
2Loss of information
If practitioners use traditional devices to collect comprehensive facial and dental information, then information completeness may be improved, but ease of operation and time consumption deteriorate
Solution Approach 1:
The system enables automated data collection and analysis where the smartphone and AI algorithms perform the work of information gathering and processing. The depth-sensing camera automatically captures comprehensive facial geometry, and machine learning models autonomously identify landmarks and calculate measurements, reducing the practitioner's manual effort while ensuring complete anatomical information is captured.
Solution Approach 2:
The system performs preliminary actions by automatically capturing all necessary facial and dental information in a single scan session before treatment planning begins. The AI models pre-process the data to identify all anatomical landmarks and generate measurements, so practitioners receive ready-to-use comprehensive information without manual data collection steps.
3Ease of operation
If practitioners rely on limited views of patient anatomy, then ease of operation is maintained, but measurement precision and treatment planning quality deteriorate
Solution Approach 1:
The patent transitions from 2D facial photographs to 3D depth-mapped facial models using a depth-sensing camera. This dimensional enhancement provides comprehensive spatial information about facial anatomy, allowing practitioners to view and measure structures from multiple angles without leaving the digital environment, thus maintaining ease of operation while dramatically improving measurement precision.
