Solution Overview
Problem
Conventional dental charting is largely manual and lacks automation, making it inefficient for generating and updating electronic dental records from patient images, and it does not effectively utilize the potential of digital image analysis for accurate and comprehensive tooth charting.
Innovation Solution
A method and system that automatically generate and update electronic dental charts using digital image analysis from various types of dental images, incorporating computer-aided diagnostic tools to identify tooth conditions and treatments, and allowing presentation in both 2-D and 3-D formats, with integration of imaging apparatus, host processors, and databases for data storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual dental charting is used with paper templates, then the process is simple and straightforward, but it is inefficient and time-consuming for generating and updating electronic dental records
Solution Approach 1:
The patent replaces the manual mechanical process of dental charting with an automated computer-based system. The system uses digital images of teeth, applies image processing algorithms to automatically identify tooth structures and conditions, and generates electronic dental charts without manual intervention, thereby dramatically improving efficiency and eliminating time loss associated with manual charting.
Solution Approach 2:
The system enables self-service automatic charting by allowing the computer to autonomously perform tooth identification, condition assessment, and chart generation from digital images. The automated diagnostic tools and image analysis algorithms independently complete the charting process without requiring dental practitioners to manually annotate or interpret each tooth, thus resolving the productivity-time loss contradiction.
2Measurement precision
If conventional manual charting methods are used, then the process is straightforward, but it does not effectively utilize digital image analysis for accurate and comprehensive tooth charting
Solution Approach 1:
The patent implements a multi-functional automated system that performs multiple tasks: capturing digital tooth images, processing and analyzing image data, identifying tooth structures and conditions, generating electronic charts, and updating records. This universal system consolidates what would otherwise require multiple separate tools and manual steps, achieving high measurement precision through comprehensive image analysis while managing complexity through integrated design.
Solution Approach 2:
The system segments the complex charting process into distinct automated components: image acquisition, image processing, tooth identification, condition detection, and chart generation. Each segment handles a specific aspect of the analysis, allowing the system to achieve high precision through specialized algorithms for each task while organizing complexity into manageable modular functions.
3Productivity
If automated tooth charting using digital image analysis is implemented, then efficiency and accuracy are improved, but the system complexity increases
Solution Approach 1:
The patent introduces an intermediary layer of image processing algorithms and automated diagnostic tools that bridge the gap between raw digital tooth images and structured electronic dental charts. This intermediary system automatically extracts relevant features, identifies tooth conditions, and structures the data into standardized chart formats, thereby improving productivity while containing system complexity within a dedicated processing layer that can be independently developed and maintained.

AI summary
A method for generating an electronic dental chart for a patient, executed at least in part by a host processor, obtains image data for each of a number of teeth of the patient and generates a template dental chart for the patient that represents the position of each imaged tooth with a symbol according to the obtained image data. The template dental chart for each imaged tooth symbol is populated to form the electronic dental chart by associating the obtained image data to the corresponding symbol in the template dental chart for the imaged tooth, analyzing the obtained image data to identify a condition of the imaged tooth, associating at least the identified condition with the symbol for the imaged tooth, and displaying the populated electronic dental chart, wherein the displayed electronic dental chart provides a visual indication of the identified condition.
