Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant systems face challenges in aligning implants with pre-planned superstructures, leading to misalignment and potential irritation to soft tissue, prolonged healing times, and increased risk of fracture and bacterial infection due to gaps between implant and superstructure connection interfaces.
Innovation Solution
A dental implant kit with a retraction interface and a retraction member that allows for the adjustment of implant position relative to the superstructure, using threaded parts with opposing thread directions to close gaps and eliminate the need for separate abutments, thereby improving precision and reducing tissue irritation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If telescopic abutments are used to compensate for implant misalignment, then the superstructure can be connected to the implant, but soft tissue irritation occurs and healing time is prolonged
Solution Approach 1:
The implant system incorporates adjustable height mechanisms that allow the implant to be dynamically adapted to the planned position. The implant body can be adjusted vertically within the bone to achieve precise alignment with the pre-fabricated superstructure, eliminating the need for telescopic abutments that cause soft tissue irritation.
Solution Approach 2:
The superstructure is pre-fabricated based on planned implant positions before the actual surgery. This preliminary action allows for precise positioning and design of the connection interface, enabling direct connection without intermediate telescopic components that would irritate soft tissue.
2Reliability
If implants are installed deeper than planned positions, then the implant can be securely anchored in bone, but a gap occurs between the implant and superstructure connection interfaces
Solution Approach 1:
The implant system allows for vertical adjustment of the implant body within the bone after insertion. This dynamic adjustment capability enables the implant to be positioned at the optimal depth for both secure anchoring and precise alignment with the superstructure connection interface, eliminating gaps.
Solution Approach 2:
The implant depth and position parameters can be modified after initial insertion. The system allows changing the implant's vertical position within the bone to achieve the correct alignment with the superstructure while maintaining secure anchoring, thus resolving the gap issue without compromising reliability.
3Adaptability or versatility
If separate abutments are used to connect implant and superstructure, then misalignment can be compensated, but device complexity increases and fracture risk increases
Solution Approach 1:
The implant system integrates the connection interface directly into the implant body, merging the functions of the implant and abutment into a single component. This eliminates separate abutments and reduces device complexity while maintaining the ability to compensate for position variations through implant adjustment mechanisms.
Solution Approach 2:
The implant body is designed to perform multiple functions: anchoring in bone, accommodating adjustment mechanisms for position variation, and providing the connection interface for the superstructure. This multi-functionality eliminates the need for separate abutments and reduces overall device complexity.
4Adaptability or versatility
If separate abutments are used to connect implant and superstructure, then misalignment can be compensated, but the risk of fracture and bacterial infection increases due to gaps
Solution Approach 1:
The connection interface is integrated directly into the implant body, eliminating gaps between separate components. This merging of functions removes the pathways for bacterial infiltration and reduces stress concentration points that could lead to fracture, while still allowing for position adjustment through the implant's internal mechanisms.
Solution Approach 2:
The superstructure is pre-fabricated with connection interfaces designed to match the implant's adjustment range. This preliminary design ensures that when the implant is adjusted to the correct position, a direct gap-free connection is achieved, eliminating infection pathways and fracture risks associated with separate abutments.
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
This solution enhances precision in surgical procedures, reduces healing time, minimizes the risk of implant failure, and improves osseointegration by ensuring accurate alignment and contact between implants and superstructures, while reducing mechanical stress and bacterial infections.
Implementation Method 1
The external threads (5) have a first thread direction and the internal threads (7a, 7b) have a second thread direction that is opposed to that of the external threads (5). When the fastening element is tightened, the implant is pulled towards the superstructure, closing the gap.

AI summary
The application relates to an implant for insertion into a structure, a method for connecting a superstructure to the implant, and a kit comprising the implant and a superstructure. The implant comprises a body having an external surface for apposition to bone, an apical end and a coronal end, an insertion interface at the coronal end for engagement with an insertion tool and for inserting the implant in an insertion direction, a connection interface adapted to connect the implant to an connection interface of a superstructure, and a retraction interface for engagement with a retraction member when the superstructure is positioned for connection to the connection interface and being configured for retracting the implant from an applied position in a retraction direction. A gap between the connection interface of the implant and the connection interface of the superstructure may be at least reduced by retracting the implant towards the superstructure.
