3D Tooth Extraction Socket Modeling From Surface and Density Scans
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental restoration and prosthetics design tools lack information about the socket profile of extracted anatomical objects, leading to poor-fitting or misaligned prosthetics and patient discomfort due to the reliance on surface data alone, which does not account for hidden structures like bone or other internal contours.
Innovation Solution
A computer-implemented method generates a 3-dimensional model by integrating surface and volumetric density scans to create a socket model that accurately represents the anatomical cavity, including both visible and invisible portions of the extraction object, using labeled segments and neural networks for object recognition and segmentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surface scan data alone is used for dental restoration planning, then the process is simple and fast, but the accuracy of socket profile representation is poor
Solution Approach 1:
The patent combines surface scan data and volumetric density scan data into a single integrated 3D model. The surface scan provides external contours while the volumetric density scan provides internal bone structure information. These two data sources are merged through coordinate system transformation and data fusion algorithms to create a comprehensive socket profile model that includes both visible and hidden anatomical structures.
Solution Approach 2:
The patent introduces an intermediary processing system that acts as a mediator between the surface scan data and volumetric density scan data. This intermediary component performs coordinate system alignment, data registration, and fusion operations to integrate the two different data types into a unified 3D representation of the socket profile, resolving the complexity of direct integration.
2Reliability
If surface scan data alone is used, then the workflow is quick, but prosthetics may be misaligned causing patient discomfort
Solution Approach 1:
The patent performs preliminary integration of surface and volumetric scan data during the treatment planning phase to create an accurate 3D socket profile model before prosthetic fabrication. This preliminary action ensures that the socket geometry, including hidden bone structures, is accurately represented in advance, allowing for precise prosthetic alignment and fitting without requiring additional adjustment time during patient visits.
3Loss of information
If only visible surface structures are modeled, then the modeling process is straightforward, but hidden bone structures are not accounted for
Solution Approach 1:
The patent transitions from 2D surface representation to 3D volumetric representation by integrating volumetric density scan data. This dimensional change allows the model to capture hidden bone structures and internal anatomical features that cannot be represented in 2D surface scans alone. The 3D volumetric data provides depth information and internal structure visualization, enabling comprehensive socket profile analysis.
