Dental Implant Elastic Layer Absorbs Mastication Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implant units made of rigid materials transmit impact forces to the alveolar bone during mastication, causing discomfort due to their inability to allow minute movements in up and down or lateral directions, mimicking natural tooth functionality.
Innovation Solution
Incorporating an elastic layer, potentially made of the same material as the abutment or fixture, on the abutment, fixture, or implant structural body, which can absorb impact forces by allowing minute movements, and may be formed as an elastic spring or a soft membrane surrounding a core, to reduce transmission of external forces to the alveolar bone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid materials are used for abutment and fixture, then strength and rigidity are improved, but impact transmission to alveolar bone increases causing pain
Solution Approach 1:
The patent introduces an elastic layer that changes the mechanical parameters of the implant unit by providing flexibility and elasticity. This elastic layer allows the implant to deform elastically under impact forces, absorbing and dissipating energy that would otherwise be transmitted to the alveolar bone, thus resolving the contradiction between maintaining strength and reducing impact transmission.
Solution Approach 2:
The patent combines rigid materials (for the abutment and fixture to maintain strength) with elastic materials (to reduce impact transmission). This composite structure allows different parts of the implant unit to have different mechanical properties - the rigid portions provide structural strength while the elastic layer provides shock absorption, thereby resolving the contradiction between strength and impact transmission.
2Stability of the object's composition
If tight mechanical engagement is provided between abutment and fixture, then stability is improved, but minute movement during mastication is prevented causing impact transmission
Solution Approach 1:
The elastic layer changes the mechanical parameters of the connection between abutment and fixture by introducing elasticity. This allows the connection to maintain stability through elastic deformation while still permitting minute movements during mastication, thus resolving the contradiction between stability and movement capability.
Solution Approach 2:
The patent introduces dynamic characteristics to the implant unit through the elastic layer, which allows the structure to adapt its rigidity based on applied forces. During normal function, the elastic layer permits minute movements, but under excessive force, it provides shock absorption, thereby resolving the contradiction between stability and movement capability.
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 layer enables minute movements during mastication, reducing pain and providing a more natural feel by absorbing impact forces, and can be easily applied to other bone tissues beyond teeth.
Implementation Method 1
at least one of the abutment and the fixture has an elastic layer
