Dental Implant Elastic Member and Ring Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tooth implant systems experience mechanical stress issues due to the absence of dampening or cushioning, leading to potential collapse of the abutment, loosening of the abutment screw, and damage to the bone and fixture, especially under continuous chewing and grinding forces.
Innovation Solution
Incorporation of an elastic member between the upper and lower abutments in the tooth implant system, which provides a softer and resilient cushioning effect, using materials like plastic, rubber, or gold, and a ring lock mechanism to secure the elastic member, ensuring no food particles are trapped and enhancing the implant's stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a screw structure is used to fix the abutment to the fixture, then the abutment is securely attached, but mechanical stress concentrates at the top portion of the fixture causing damage to the abutment screw and bone
Solution Approach 1:
An elastic member is introduced as an intermediary component between the abutment and the fixture. This elastic member absorbs and distributes mechanical stress, preventing stress concentration at the fixture top portion while maintaining secure abutment fixation. The elastic member acts as a mediator that protects both the abutment screw and surrounding bone from excessive mechanical stress.
2Stability of the object's composition
If a rigid connection is used between abutment and fixture, then structural stability is achieved, but the abutment may collapse downwards under chewing and grinding forces
Solution Approach 1:
The connection between abutment and fixture is changed from rigid to elastic by introducing an elastic member. This parameter change allows the connection to maintain structural stability while providing the flexibility needed to prevent abutment collapse under occlusal forces. The elastic properties enable the system to absorb and dissipate mechanical energy from chewing and grinding.
3Ease of operation
If the gap between upper and lower abutment is left open, then easy cleaning is achieved, but food particles may be trapped between the abutments
Solution Approach 1:
The elastic member functions as a flexible seal that fills the gap between the upper and lower abutments. This flexible membrane prevents food particle trapping while maintaining cleaning accessibility. The elastic properties allow the member to conform to the abutment surfaces and create an effective seal without completely closing the gap, enabling proper cleaning while preventing food impaction.
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 elastic member effectively distributes mechanical stress, reducing the risk of abutment collapse and bone damage, while the ring lock ensures a secure and food-particle-free interface, enhancing the durability and functionality of the tooth implant system.
Implementation Method 1
The elastic member is securely placed between the upper abutment and the lower abutment providing softer and elastic, yet resilient, cushion between the upper abutment and the lower abutment

AI summary
A tooth implant system has an upper abutment, a lower abutment, a crown, and an elastic member securely placed between the upper abutment and the lower abutment providing softer and elastic, yet resilient, cushion between the upper abutment and the lower abutment. To better affix the elastic member within the tooth implant system, a ring lock may be used, securely placed in a ring-lock groove located on the lower abutment section. An insertion of a screw deeper into the lower abutment receptacle pushes the ring lock-groove and the ring lock outwardly to force the elastic member against an inner chamber wall of the upper abutment and into the abutment groove to better securely affix the elastic member.
