Orthodontic Virtual Modeling File Encoding Tooth Movement Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthodontic virtual modeling technologies require separate 3D files for each treatment step, leading to increased storage needs and rendering lag, as well as inefficiencies in displaying tooth movement and gingiva adaptation over time.
Innovation Solution
A virtual modeling file format that encodes tooth shape, position, and movement data using transformation matrices, allowing real-time adaptation and minimizing storage by including only key gingiva information, enabling efficient rendering and storage of an entire treatment plan in a single file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate 3D files are used for each treatment step, then complete treatment plan visualization is achieved, but storage requirements increase and rendering lag occurs
Solution Approach 1:
The patent combines multiple separate 3D treatment step files into a single integrated virtual modeling file. The file structure merges treatment plan data, tooth geometry, and gingiva geometry into one unified format, eliminating the need for multiple separate files while maintaining complete treatment plan visualization capability.
Solution Approach 2:
The virtual modeling file format is designed to serve multiple functions simultaneously: storing treatment plan sequences, containing 3D tooth and gingiva geometries, encoding transformation matrices for tooth movement, and providing rendering instructions all in a single file structure. This multi-functionality replaces what previously required multiple specialized files.
2Reliability
If separate 3D files are used for each treatment step, then detailed treatment steps can be displayed, but rendering performance decreases due to processing multiple files
Solution Approach 1:
By merging all treatment step data into a single virtual modeling file, the system eliminates the overhead of loading and processing multiple separate files. The unified file structure allows the rendering engine to access all treatment step information in one operation, significantly improving rendering speed while maintaining the ability to display detailed treatment steps.
Solution Approach 2:
The patent performs preliminary organization of all treatment step data, tooth geometries, and transformation matrices during the file creation phase. This pre-processing allows for efficient random access to any treatment step during rendering without requiring sequential file loading, thereby enhancing rendering performance.
3Reliability
If complete gingiva geometry data is stored for each treatment step, then realistic gingiva adaptation is achieved, but file size increases significantly
Solution Approach 1:
The patent extracts and stores only the essential gingiva geometry data required for realistic adaptation rather than complete detailed geometry for each treatment step. By taking out only the critical gingiva information needed for visual realism, the file size is reduced while maintaining acceptable rendering quality.
Solution Approach 2:
The virtual modeling file applies different quality levels to different parts of the model. High-detail tooth geometries are maintained for accurate treatment visualization, while gingiva geometry uses a more optimized representation that provides realistic adaptation effects with reduced data requirements. This local quality differentiation optimizes the balance between realism and file size.

AI summary
According to embodiments of the disclosed subject matter, a server can include processing circuitry configured to receive a virtual modeling file encoded with an orthodontic treatment plan such that the encoded information of the virtual modeling file format allows all steps of the orthodontic treatment plan to be displayed without a separate file for each treatment step. Additionally, the processing circuitry can be configured to download a first treatment step of the virtual modeling file format, receive gingiva and teeth geometries corresponding to the first treatment step, and display the first treatment step. Further, a selected treatment step can be displayed based on information encoded into the orthodontic virtual modeling file format.
