Denture Fixing Attachment with Ball Joint for Inclined Fixture Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional abutment technologies for fixing dentures are inconvenient when fixtures are not arranged in parallel, requiring additional parts or reoperations to couple the denture, especially when fixtures have inclination angles.
Innovation Solution
A denture-fixing attachment with a rotation guide member and a ball joint system that allows for adjustable angles and positions, eliminating the need for additional parts and simplifying the coupling process by compensating for inclination angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional abutment technologies are used to fix dentures, then the fixtures can be securely implanted in the alveolar bone, but additional parts and reoperations are required when fixtures are not arranged in parallel
Solution Approach 1:
The abutment is designed with a ball joint mechanism that allows dynamic adjustment of the abutment's angle and position relative to the fixture. This dynamic capability enables the abutment to adapt to non-parallel fixture arrangements without requiring additional surgical interventions or extra components, thereby resolving the contradiction between secure implantation and device complexity
Solution Approach 2:
The ball joint mechanism changes the angular and positional parameters of the abutment to match the actual arrangement of fixtures. By allowing continuous adjustment of these parameters within a reasonable range, the system can accommodate various fixture configurations without requiring additional parts or reoperations
2Adaptability or versatility
If fixtures are implanted with inclination angles, then the implant treatment can be performed, but additional parts are needed to couple the denture
Solution Approach 1:
The ball joint mechanism provides dynamic adjustability that allows the abutment to compensate for fixture inclination angles. This eliminates the need for additional coupling parts by enabling the abutment itself to adapt to the inclined fixture arrangement through angular adjustment
3Reliability
If conventional abutment coupling methods are used, then the denture can be fixed, but treatment time is extended and patient burden increases
Solution Approach 1:
The dynamic ball joint mechanism allows for simplified coupling procedures by eliminating the need for additional parts and reoperations. This reduces treatment time and patient burden while maintaining reliable denture fixation through the adjustable abutment-fixture connection

Function Achieved in This Case
This solution reduces the need for additional surgical operations, shortens treatment time, reduces patient and operator burdens, and extends the lifespan of the fixture by evenly distributing chewing pressure.
