Virtual Dental Model Base Generation for Orthodontic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating virtual teeth models lack consistency and accuracy in positioning, failing to meet regulatory standards for dental applications, particularly in orthodontic treatments.
Innovation Solution
A method for generating a digital model base from a patient's dentition involves obtaining prescribed dimensions, determining bounding dimensions of a 3D digital model, automatically forming a digital model base, and displaying or storing the virtual model base with the 3D digital model, ensuring repeatable and accurate positioning compliant with dental regulatory requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning methods are used for virtual teeth models, then flexibility in model placement is maintained, but positioning consistency and accuracy deteriorate, failing to meet regulatory standards
Solution Approach 1:
The system automatically determines bounding dimensions and generates base models without manual intervention. The computer-executable instructions autonomously process the 3-D digital model to extract bounding dimensions and generate the base model, eliminating the need for manual positioning while ensuring consistent, accurate results that meet regulatory standards.
Solution Approach 2:
The system uses prescribed dimensions as parameters to automatically generate base models with consistent positioning. By defining specific dimensional parameters (length, width, height) that must be maintained across all base models, the system ensures regulatory compliance while automating the generation process, resolving the contradiction between automation complexity and positioning accuracy.
2Reliability
If automated base generation is implemented, then positioning consistency improves, but system complexity increases
Solution Approach 1:
The system performs preliminary determination of bounding dimensions from the 3-D digital model before generating the base model. By pre-calculating the bounding dimensions and using them as input parameters for base generation, the system ensures consistent, repeatable positioning while maintaining a relatively simple automated process that doesn't require complex iterative adjustments.
3Measurement precision
If regulatory compliance is strictly enforced, then positioning accuracy improves, but processing time increases
Solution Approach 1:
The system replaces manual mechanical positioning processes with automated computer-based generation. The computer-executable instructions automatically generate base models that comply with regulatory standards, eliminating the need for time-consuming manual adjustments while ensuring consistent accuracy. This substitution maintains productivity by automating the compliance-checking process rather than requiring iterative manual refinement.

AI summary
Method and/or apparatus embodiments can provide a virtual orthodontic base, adapted to each virtual 3D dental model of the teeth (e.g., upper and lower jaw). The virtual orthodontic base should match each 3D model (e.g., size), conform to prescribed dimensional requirements and still be rapidly calculated. The 3D virtual teeth model can be provided or reconstructed (e.g., from a laser scanning, intra oral camera scanning or x-ray scan of a plaster, a negative impression (e.g., alginate or silicon) of a patient's dentition or directly from the patient's mouth).
