Dental Coloring Material Composition for Precise Color Tone Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental materials struggle to accurately reproduce complex and varied natural tooth colors, especially when using subtractive primary colors, as they often require additional colors like black to achieve complete color tones, limiting their aesthetic and chromatic flexibility.
Innovation Solution
A dental composition comprising a polymerizable monomer, polymerization catalyst, and pigments or dyes based on cyan, magenta, and yellow subtractive primary colors, optionally combined with white, black, and transparent colors, allowing for precise color tone reproduction using the Munsell color system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stain materials with preliminarily adjusted color tones containing multiple coloring materials are used, then the color tone can be adjusted to some extent, but the color development structure becomes more complicated and it becomes difficult to obtain the desired color tone
Solution Approach 1:
The invention divides the color adjustment function into separate, pure color components (red, blue, green stains) rather than using pre-mixed complex color tones. Each stain contains a single coloring material, allowing operators to selectively combine only the necessary colors, thereby simplifying the overall color development structure while maintaining versatility.
Solution Approach 2:
The invention provides pure color stains that can be applied locally to specific areas where color adjustment is needed. Instead of using a complex pre-mixed stain that requires thorough mixing and has unpredictable color development, the pure color stains can be applied precisely where required, simplifying the color development process.
2Quantity of substance
If conventional stain materials with pure colors are used, then the color can be intense, but there is a limitation on the desired color mixture due to chromatology and subtractive color mixture
Solution Approach 1:
The invention segments the color mixture process by providing separate pure color stains (red, blue, green) that can be independently applied and mixed in any proportion. This allows operators to create custom color tones by combining these basic colors, overcoming the limitations of conventional pre-mixed stains while maintaining the ability to achieve intense colors.
Solution Approach 2:
The invention enables dynamic color adjustment by allowing operators to mix different proportions of pure color stains based on the specific color tone required. The stains can be applied in varying amounts and combined in different ratios, providing flexible color matching capability that adapts to various dental aesthetic requirements.
3Manufacturing precision
If multiple coloring materials are blended in preliminarily adjusted color tones, then the color tone can be reproduced, but a more complicated color development structure is imparted making it difficult to obtain the desired color tone
Solution Approach 1:
The invention segments the coloring materials into separate pure color stains (red, blue, green) rather than using pre-blended multiple coloring materials. This segmentation allows operators to mix only the necessary colors in simple proportions, maintaining color tone reproduction accuracy while significantly easing the mixing process and reducing the complexity of color development.
Solution Approach 2:
The invention extracts the individual coloring materials from the pre-mixed stain formulations and provides them as separate pure color components. This extraction allows operators to selectively combine only the necessary colors for their specific color tone requirements, simplifying the mixing process while maintaining precision in color tone reproduction.
