Dental Implant Abutment Adaptor for Precise Prosthetic Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant systems face challenges in achieving precise attachment between the implant abutment and prosthetic, often leading to adhesive overflow and requiring complex adjustments during implant procedures, which can compromise the functional and aesthetic outcomes.
Innovation Solution
An adaptor for dental implant abutments is designed with a body featuring a longitudinally extending bore, a distal shaft that tapers in diameter, and a proximal flange with multiple ledges to enhance secure attachment, minimizing adhesive overflow and simplifying the implant procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional attachment methods are used between implant abutment and prosthetic, then the attachment can be achieved, but adhesive overflow occurs and complex adjustments are required
Solution Approach 1:
The adaptor serves as an intermediary component between the implant abutment and the prosthetic. It includes a bore for receiving the abutment post and a distal shaft for insertion into the prosthetic, with ledges that provide precise positioning surfaces. This intermediary structure eliminates the need for complex adjustments by ensuring proper alignment and spacing during the bonding process, thereby preventing adhesive overflow while maintaining procedural simplicity.
2Manufacturing precision
If the adaptor includes a tapered distal shaft, then precise placement and secure bonding are achieved, but the manufacturing complexity increases
Solution Approach 1:
The adaptor features a distal shaft with a tapered geometry where the outer diameter decreases toward the distal end. This parameter change in the shaft dimensions provides self-aligning and self-centering characteristics during insertion into the prosthetic, ensuring precise placement. The taper angle is specifically designed to facilitate easy insertion while maintaining positional accuracy, thus achieving precise placement without significantly increasing manufacturing complexity.
3Reliability
If the proximal flange includes multiple ledges, then secure attachment and adhesive containment are improved, but the device complexity increases
Solution Approach 1:
The proximal flange of the adaptor includes multiple ledges with different functions: a first ledge for abutting the abutment to provide proximal support, a second ledge for abutting the prosthetic to contain adhesive, and a third ledge for abutting gum tissue to provide biological interface support. Each ledge is positioned at a specific location with specific geometric properties to perform its localized function. This distribution of specialized features throughout the flange structure achieves secure attachment and adhesive containment without requiring complex overall device design.
