Detachable Dental Attachment Device with O-Ring Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixed dental implant attachment systems are costly and complex, requiring skilled professionals and involving cement or screws, which restricts accessibility and increases maintenance costs, while also causing discomfort due to tissue-borne dentures.
Innovation Solution
A detachable fixed dental attachment device comprising a cap and abutment with O-Ring or O-Ball geometry, designed for periodic removal by clinicians, providing rigid connection to dental implants and reducing maintenance needs, allowing for immediate load distribution and improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fixed dental implant attachment systems using cement or screws are used, then the denture feels more like natural teeth with less food entrapment, but the treatment cost increases and the procedure becomes more complex
Solution Approach 1:
The attachment system is divided into separate components: an implant component anchored in the jawbone and a denture component with corresponding attachment elements. This segmentation allows for a simpler overall procedure compared to traditional cement or screw-retained systems, while still providing fixed retention that distributes occlusal loads to the implant and jawbone, improving patient comfort and reducing food entrapment.
2Ease of operation
If conventional fixed dental implant attachment systems are used, then the denture feels more like natural teeth, but the treatment cost and laboratory fees increase
Solution Approach 1:
The attachment components are designed as simple, cost-effective elements that can be easily manufactured and replaced if needed. The system uses basic mechanical retention features rather than expensive custom abutments or specialized cementation procedures, significantly reducing treatment costs while maintaining patient comfort and fixed retention benefits.
3Reliability
If conventional fixed attachment systems are used, then fixed retention is achieved, but maintenance requires time-consuming procedures and high costs
Solution Approach 1:
The segmented design with separate implant and denture components allows for easy maintenance. If the attachment components wear or become loose, they can be quickly replaced by detaching the denture component and swapping the attachment elements, eliminating the need for time-consuming removal and replacement procedures required by conventional fixed systems.
4Ease of manufacture
If removable dentures are used, then easier cleaning and lower cost are achieved, but the denture lacks the feel of natural teeth and requires more maintenance
Solution Approach 1:
The system combines benefits of both removable and fixed dentures through segmentation. The denture component can be easily detached for cleaning like a removable denture, while the implant-anchored component provides fixed retention that distributes occlusal loads to the implant and jawbone, giving the patient the feel of natural teeth. This eliminates the compromise between comfort and maintainability.
