Customized Dental Prosthesis Root-Shaped Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental restoration and prosthetic options, such as bridges and osseointegrated implants, are invasive, have limited lifespan, and often lead to chronic infections and structural issues, with a lack of custom solutions that integrate well with the patient's existing periodontal structure.
Innovation Solution
A method for manufacturing a customized dental prosthesis with a root-shaped structure that mimics the natural tooth, using intra-oral 3D imaging to create a virtual model, optimizing the shape for integration, and coating with a substance promoting bone ingrowth, allowing for reduced invasive procedures and improved stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bridges or osseointegrated implants are used to replace missing teeth, then tooth replacement is achieved, but adjacent healthy enamel is destroyed or chronic local infections occur
Solution Approach 1:
The prosthesis is divided into multiple segments including a root portion, abutment, and crown, with each segment serving a specific function. The root portion is designed to integrate with bone while the abutment and crown provide restorative function, allowing the replacement to be customized without affecting adjacent healthy teeth
Solution Approach 2:
The prosthesis features localized functional zones with different properties: the root portion has surface characteristics optimized for osseointegration, the abutment provides mechanical connection, and the crown restores aesthetics and function. This localized quality allows each part to perform its specific function while minimizing harm to surrounding structures
2Productivity
If conventional prostheses are manufactured, then production efficiency is maintained, but customization and integration with patient's existing structure are limited
Solution Approach 1:
Three-dimensional data of the patient's oral structure is captured and a virtual model is created before the actual prosthesis manufacturing begins. This preliminary digital planning allows complete customization of the prosthesis design to match the patient's specific anatomy, and the customized prosthesis can be fabricated using automated manufacturing processes
Solution Approach 2:
The patient's existing oral structures are digitally scanned and copied to create an accurate virtual model. This digital copy serves as the basis for designing the customized prosthesis, ensuring perfect integration with the patient's existing anatomy while enabling automated manufacturing from the digital design
