Patient-Specific 3D Dental Model Color-Texture Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional dental models lack patient specificity in color and texture, failing to accurately represent individual tooth colors, cavities, fillings, and other features, as they use generic colorization and uniform tones.
Innovation Solution
A method and system that generate a patient-specific color-textured three-dimensional dental model by projecting two-dimensional intra-oral photographs onto a three-dimensional dental model, dividing it into sections based on anatomical landmarks, and indexing and projecting data from the photographs onto corresponding sections to create a realistic color-textured surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If generic colorization is used for three-dimensional dental models, then the geometric shape is accurately represented, but the visual resemblance to patient's actual dentition is poor
Solution Approach 1:
The patent applies copying by projecting two-dimensional color and texture information from patient-specific photographs onto the three-dimensional dental model. This transfers the visual characteristics (color, texture, patterns) from the 2D images to the 3D model surface, creating a realistic representation that preserves both geometric accuracy and visual fidelity to the patient's actual dentition
2Ease of manufacture
If uniform color tone is applied to all teeth and gingival areas, then the model creation process is simplified, but patient-specific features such as cavities, fillings, and crowns are obscured
Solution Approach 1:
The patent applies local quality by dividing the three-dimensional dental model into multiple sections corresponding to different anatomical regions (anterior, right posterior, left posterior). Each section is then textured with patient-specific color and texture information from corresponding photographs, allowing different parts of the model to have different visual characteristics that accurately represent the patient's unique dentition features
3Adaptability or versatility
If three-dimensional scanning is used to create dental models, then computerized treatment planning becomes possible, but the models lack realistic color and texture representation
Solution Approach 1:
The patent applies merging by combining the geometric data from three-dimensional scanning with the color and texture data from two-dimensional photographs. The 3D scan provides the accurate geometric shape and spatial information, while the photographs provide the visual characteristics. By merging these two data sources through projection and texturing, the system creates a comprehensive digital model that retains both the versatility for computerized treatment planning and the realism of patient-specific color and texture representation

AI summary
A method and system for generating a color-textured three-dimensional dental model is specific to a patient is disclosed. According to one embodiment, a three-dimensional dental model that is deficient of volumetric data for a three-dimensional anatomical landmark is obtained. A two-dimensional anatomical landmark of a two-dimensional intra-oral photograph that corresponds to the three-dimensional anatomical landmark of the three-dimensional dental model is identified. The two-dimensional intra-oral photograph is projected onto the three-dimensional dental model. The three-dimensional anatomical landmark is calculated from the projection of the two-dimensional anatomical landmark of the two-dimensional intra-oral photograph.
