Movable Cap Magnetic Denture Attachment for Gingiva Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dental attachments combined during the denture-making process concentrate occluding stress on the gingiva, leading to discomfort and the need for frequent modifications due to unpredictable gingiva shrinkage, as the dental attachment cannot adapt to shape changes.
Innovation Solution
A dental attachment with a movable cap made of non-magnetic material, allowing relative movement between the attachment main body and the keeper, which can adjust to gingiva changes, reducing stress concentration and enabling integration during the denture-making process without initial oral space stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the dental attachment is combined with the denture in the making process, then the denture can be completed with the attachment, but occluding stress is concentrated on the gingiva causing discomfort and requiring frequent modifications
Solution Approach 1:
The cap is designed to be movable relative to the attachment main body, allowing dynamic adjustment between a contacting position and an extended position. This mobility enables the attachment to adapt to gingiva shrinkage over time, preventing stress concentration while maintaining the ability to be combined during the making process
Solution Approach 2:
The cap can change its position parameter relative to the attachment main body, moving from contacting the head portion to being extended away by a certain distance. This parameter change allows the system to accommodate dimensional changes in the gingiva without transferring stress to the artificial teeth
2Object-affected harmful factors
If the dental attachment is combined after the denture is made, then stress on the gingiva is alleviated initially, but the gingiva shrinks over about half a year requiring modification and recombination
Solution Approach 1:
The movable cap design allows the attachment to continuously adapt to gingiva changes throughout the usage period, eliminating the need for periodic modifications and recombination procedures that would otherwise be required every half year
3Productivity
If the denture is made on a model without adequate adaptation to oral space, then the fabrication process is efficient, but the artificial teeth and denture base shrink according to gingiva shape change causing discomfort
Solution Approach 1:
The movable cap provides a mechanism for the rigid denture structure to dynamically compensate for dimensional changes in the gingiva, allowing the denture made on a model to remain adaptable to oral space changes without requiring precise pre-adaptation
Solution Approach 2:
By allowing the cap position parameter to change, the system compensates for the fixed dimensions of the model-based fabrication, enabling adaptation to actual oral space variations that occur after denture placement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for reduced stress on the gingiva and eliminates the need for post-fabrication adjustments, enabling the denture with the dental attachment to adapt to gingiva changes, thereby enhancing patient comfort and reducing the frequency of modifications.

AI summary
A dental attachment is embedded in a denture base so as to attach to a keeper made of a soft magnetic material built in a tooth root by magnetic attractive force. The dental attachment comprises an attachment main body which has a magnetic body delivering magnetic attractive force and a cap which covers a head portion located on the opposite side of an attractive surface to attach the keeper of the attachment main body. The cap, made of a non-magnetic material, is installed in the attachment main body so as to be able to move between a contacting position (A) which contacts with the head portion and an extended position (B) which is far from the head portion for a certain distance.
