Abutment Attachment L-Shaped Adhesive Base Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abutment attachments for jaw implants limit the angular range for gluing an adhesive body, making it difficult to achieve a stable and large adhesive surface while maintaining material thickness and easy screw insertion.
Innovation Solution
An L-shaped adhesive base with a tongue-shaped or pin-shaped section, offset from the fastening screw opening, allows for a high bevel adhesive body attachment without compromising material thickness, and includes design features like a circular arc cross-section and beveled collar to enhance stability and ease of placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the adhesive base is positioned centrally on the abutment attachment, then the fastening screw can be easily inserted, but the angular range for gluing the adhesive body is limited and the adhesive surface area is reduced
Solution Approach 1:
The adhesive base is repositioned from a central location to a lateral position on the abutment attachment. This spatial reconfiguration in another dimension (from central axis to lateral offset) simultaneously increases the angular range for gluing operations and maintains adequate adhesive surface area by utilizing the lateral space that would otherwise be unused.
2Strength
If the adhesive base is enlarged to provide a larger adhesive surface, then the integral strength increases, but the material wall thickness decreases and screw insertion becomes difficult
Solution Approach 1:
Instead of enlarging the adhesive base in the radial direction (which would reduce wall thickness), the base is extended in the lateral direction away from the central axis. This dimensional shift allows the adhesive surface area to increase while maintaining the original wall thickness and clearances necessary for screw insertion.
Solution Approach 2:
The abutment attachment structure is segmented into distinct functional zones: a central region for fastening screw insertion and a lateral region for the enlarged adhesive base. This segmentation allows each zone to be optimized independently - the central region maintains its original dimensions for proper screw fit, while the lateral region provides extended adhesive surface area.
3Manufacturing precision
If the adhesive base section has sharp edges for precise positioning, then the adhesive body can be accurately positioned, but the adhesive body may tilt during placement and the structure is more difficult to manufacture
Solution Approach 1:
The sharp edges of the adhesive base section are replaced with rounded edges having a defined radius of curvature. This curvilinear design eliminates the manufacturing complexity and susceptibility to damage associated with sharp edges, while still providing adequate positioning accuracy through the rounded geometric features that guide the adhesive body into proper alignment.
