Modular Rigid Framework for Dental Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of permanent dental prostheses is lengthy and costly, limiting access to implant dentistry for many edentulous or partially edentulous individuals due to complex and time-consuming procedures.
Innovation Solution
A rigid frame for dental restoration comprising interconnected pillars and plates made of metallic materials, such as titanium or chromium/cobalt alloys, with a fiberglass thread or resin as connecting elements, allowing for quick assembly and adaptation to the patient's anatomy using conical abutments on implants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional permanent dental prosthesis procedures are used, then the prosthesis is durable and functional, but the treatment process is lengthy and costly
Solution Approach 1:
The framework is divided into separate modular components including abutments, plates, and connecting elements that can be fabricated independently and assembled quickly during the surgical procedure, eliminating the need for lengthy traditional prosthesis fabrication processes while maintaining structural integrity
Solution Approach 2:
The framework components are pre-designed and prepared in advance with precise geometries and connection interfaces, allowing for rapid assembly during surgery without requiring complex intraoperative fabrication steps, thus reducing treatment time while ensuring prosthesis reliability
2Reliability
If traditional permanent dental prosthesis procedures are used, then the prosthesis is functional, but the treatment cost is high
Solution Approach 1:
The framework is divided into separate modular components including abutments, plates, and connecting elements that can be fabricated independently using cost-effective manufacturing methods and assembled quickly during the surgical procedure
Solution Approach 2:
The framework uses standardized dimensions and geometries for plates and connecting elements that allow for efficient manufacturing and potential reuse of components across different patients, reducing overall production costs while maintaining functional requirements
3Strength
If the framework uses multiple plates and connecting elements, then the prosthesis rigidity is improved, but the device complexity increases
Solution Approach 1:
Reinforcement plates are strategically positioned at specific locations where structural support is most needed, such as between abutments or in areas subject to higher mechanical loads, providing targeted rigidity enhancement without adding unnecessary complexity throughout the entire framework
Solution Approach 2:
The framework combines different materials with complementary properties, including metallic materials for structural components and fiberglass-reinforced materials for connecting elements, achieving optimal rigidity-to-complexity ratio by selecting materials that provide strength where needed while simplifying other portions of the structure
