Customized Dental Blank with Multi-Color Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for manufacturing dental restorations face challenges in providing customized blanks with precise color and size matching, especially for rare colors, often requiring large stock sizes or accepting significant color tolerances, which can be costly and inefficient.
Innovation Solution
A method for creating customized dental blanks with distinct portions based on specific color schemes and dimensional information, allowing for multiple colors in a single blank, utilizing a computer-based configurator to select and manufacture these blanks from materials like ceramic or composite materials, and incorporating individual codes for precise machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standardized stock of dental blanks is maintained to cover various color requirements, then the availability of appropriate blanks for different restorations is improved, but the storage space and cost increase
Solution Approach 1:
The patent merges multiple color schemes into a single customized dental blank by creating different portions with different color schemes. This allows one blank to serve multiple restoration needs that would otherwise require separate blanks, reducing storage requirements while maintaining versatility.
Solution Approach 2:
The customized dental blank is designed to be multi-functional by incorporating multiple color schemes and dimensional variations within a single blank. This universal blank can be used for different restoration types and color requirements, replacing the need for multiple specialized blanks in stock.
2Adaptability or versatility
If a large stock of dental blanks with various colors is maintained to address rare colors, then the color selection capability is improved, but the storage requirements and costs increase
Solution Approach 1:
Multiple color schemes are combined within a single customized dental blank, creating a multi-colored blank that can address rare and varied color requirements without needing separate blanks for each color.
Solution Approach 2:
The dental blank is pre-customized with multiple color schemes and dimensional variations before use. This preliminary customization ensures that the required color and size variations are already present in the blank, eliminating the need to maintain large stocks of pre-colored blanks.
3Ease of manufacture
If standardized dental blanks are used to reduce manufacturing complexity, then the ease of manufacture is improved, but the manufacturing precision of color matching deteriorates
Solution Approach 1:
Different portions of the dental blank are assigned different color schemes and dimensional characteristics according to specific restoration requirements. This local customization allows precise color matching for each restoration site while maintaining a streamlined manufacturing process for the overall blank production.

AI summary
A method of making a customized dental blank. The method has steps of obtaining from a dental practitioner a first color scheme and a different second color scheme as well as a first dimensional information for the first color scheme and a different second dimensional information for the second color scheme. The first and second dimensional information each relate to a size and/or a location within dimensions of the dental blank. The method further has the step of manufacturing the customized dental blank which has a first portion based on the first dimensional information according to the first color scheme and a second portion based on the second dimensional information according to the second color. Further the method has the step of providing the dental practitioner with the customized dental blank. The method helps facilitating the making of a dental restoration from a blank.
