Dental Implant Head Geometry for Bone Growth and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implants experience esthetic, functional, and periodontal ramifications due to craniofacial growth, leading to unfavorable stresses on remaining dentition and complications such as opening of contacts between implant and natural teeth, discrepancies in facial alignment, and gingival margin changes.
Innovation Solution
The dental implant fixture features an elongated shaft section with a head section that includes concave or narrower surface areas designed to accommodate bone growth, preventing vertical and rotational movements and minimizing pressure, thereby compensating for jawbone deterioration caused by craniofacial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional dental implant fixture is used, then the implant provides immediate structural support, but it cannot accommodate craniofacial growth leading to esthetic, functional, and periodontal ramifications over time
Solution Approach 1:
The implant fixture incorporates a flexible or movable component that allows dynamic adaptation to craniofacial growth. The fixture can flex or move in response to growth forces, maintaining its functional integrity while accommodating changes in the jawbone and teeth position over time.
Solution Approach 2:
The implant design incorporates materials or structures that change physical parameters in response to craniofacial growth. The fixture may undergo controlled deformation, expansion, or modification of its physical properties to adapt to growing bone and teeth, thereby maintaining long-term stability.
2Stability of the object's composition
If the implant restoration is made static to maintain structural integrity, then it provides stable support, but it cannot compensate for tooth movement and occlusal changes caused by continued growth
Solution Approach 1:
The implant restoration incorporates dynamic elements that allow it to move or flex in response to occlusal changes and tooth movement. This dynamic capability enables the restoration to accommodate growth-related changes without transmitting harmful stresses to adjacent teeth, while maintaining structural integrity through controlled deformation.
3Ease of operation
If conventional implant materials are used, then the implant provides immediate functionality, but it cannot prevent bone resorption or soft tissue changes associated with craniofacial growth
Solution Approach 1:
The implant fixture utilizes composite materials that combine the immediate functionality of conventional materials with the ability to adapt to craniofacial growth. The composite structure may include flexible polymers, shape-memory alloys, or other materials that provide immediate support while undergoing controlled changes to prevent bone resorption and soft tissue deterioration over time.
