Dental Imaging Mixed Reality System for Periodontal Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assessing periodontal health are slow, painful, and inaccurate, and do not allow for easy visualization of gum disease or precise positioning of dental instruments relative to regions of interest in the mouth.
Innovation Solution
A method combining intraoral scanner and cone beam computerized tomography imaging data to generate a composite image and provide augmented reality guidance for dental procedures, using inertial sensors to track the position of dental instruments relative to anatomical landmarks, enabling precise virtual positioning and improved visualization of periodontal health.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual measurement with dental instruments is used to assess periodontal health, then the procedure can be performed with simple equipment, but the assessment is slow and does not allow easy visualization of gum disease
Solution Approach 1:
The patent replaces manual mechanical measurement with optical imaging systems (intraoral scanner and cone beam CT) that automatically capture and process dental data, eliminating the need for manual probing and measurement while providing rapid, comprehensive assessment of periodontal health
Solution Approach 2:
The patent transitions from two-dimensional manual measurements to three-dimensional digital imaging and composite modeling, enabling comprehensive visualization of periodontal structures and disease states that cannot be achieved with traditional linear measurements
2Device complexity
If manual measurement methods are used, then the equipment is simple, but visualization of current gum disease state is not easy
Solution Approach 1:
The patent merges data from multiple imaging sources (intraoral scanner surface data and cone beam CT volumetric data) into a single composite three-dimensional model that integrates both soft tissue and hard tissue information, providing comprehensive visualization of periodontal health status
Solution Approach 2:
The patent creates digital copies and three-dimensional virtual models of the patient's oral structures, allowing detailed visualization and analysis of gum disease without requiring direct physical manipulation of the patient's tissues
3Ease of operation
If traditional imaging methods are used separately, then each imaging modality is simple to operate, but precise positioning of dental instruments relative to regions of interest is difficult
Solution Approach 1:
The patent combines multiple imaging modalities (intraoral scanning and cone beam CT) into an integrated system that correlates surface anatomy with internal structures, enabling precise three-dimensional localization of regions of interest and dental instruments through registered composite coordinates
Solution Approach 2:
The patent introduces a reference object with sensors as an intermediary that establishes a common coordinate system between the imaging systems and the dental instrument, allowing accurate tracking and positioning of the instrument relative to anatomical landmarks
4Device complexity
If separate imaging modalities are used, then each imaging system is independent and simple, but comprehensive assessment of periodontal health is limited
Solution Approach 1:
The patent merges complementary information from different imaging modalities - the intraoral scanner provides detailed soft tissue surface data while the cone beam CT provides internal hard tissue and bone structure data - creating a comprehensive composite model that reveals periodontal health information neither system could provide alone
Data Source
AI summary
An imaging system is described. The imaging system accesses first imaging data of a specimen using a first sensor device. The first imaging data comprising volumetric data. The imaging system accesses second imaging data of the specimen using a second sensor device. The second imaging data comprising surface data. The imaging system registers a common anatomical region of the specimen in the first imaging data and the second imaging data and generates a composite image based on the registered common anatomical region. The composite image indicates the volumetric data and the surface data of the specimen.
