Dental Anchoring Assembly With Screw And Snap-On Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental anchoring systems either lack flexibility for easy assembly and cleaning or provide a fixed sensation that cannot be easily converted to a removable state, posing challenges for patients and caregivers, especially as they age or require care.
Innovation Solution
A dental anchoring system with a dual anchoring mode: a first mode using a fastening screw for a fixed sensation and a second mode with a snap-on or ratchet connection for easy detachment, allowing conversion between the two modes without modifying the anchoring or support elements, utilizing a non-destructive, positive-locking connection between an outer and inner part that can pivot relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening screw is used to anchor the carrier element to the anchoring element, then the patient experiences a fixed denture sensation, but the system becomes difficult to remove and clean without professional assistance
Solution Approach 1:
The system transitions from a static fixed connection to a dynamic reversible connection. The snap-on connection allows the carrier element to be easily detached and reattached by the patient, transforming the anchoring system from a permanent fixture to a removable prosthesis that can be taken out for cleaning and stored when not in use.
Solution Approach 2:
The anchoring system is divided into separable components: the anchoring element remaining in the jawbone and the carrier element with denture that can be removed. This segmentation allows the patient to detach the carrier element from the anchoring element, enabling easy cleaning of both components and the jawbone interface without requiring professional dental assistance.
2Ease of operation
If a detachable snap-on connection is used, then the system becomes easy to remove and clean, but the patient does not experience a fixed denture sensation
Solution Approach 1:
The system allows the patient to switch between a fixed sensation mode (when the snap-on connection is engaged and the carrier element is securely attached) and a removable mode (when the connection is disengaged). This dynamic capability enables the patient to enjoy the stability of a fixed denture during use while easily removing it for cleaning when needed.
3Adaptability or versatility
If the anchoring system is designed for easy conversion between anchoring modes, then the system becomes versatile and adaptable, but the device complexity increases
Solution Approach 1:
The anchoring element is designed with universal functionality to accommodate both anchoring modes. It includes a threaded bore for screw connection and a receiving section with a spherical outer part for snap-on connection. This multi-functionality allows the same anchoring element to provide either a fixed or removable connection depending on the carrier element configuration, without requiring separate anchoring structures.
Solution Approach 2:
The spherical inner part is received within the spherical outer part of the carrier element, creating a nested structure. This nested design allows the snap-on connection to be integrated within the existing carrier element geometry, minimizing additional complexity while enabling the reversible anchoring capability. The inner part can be inserted into and removed from the outer part without requiring separate anchoring components.
4Adaptability or versatility
If the outer part and inner part are made spherical to enable pivoting, then the system gains flexibility in assembly and disposal directions, but the manufacturing precision requirements increase
Solution Approach 1:
The outer part and inner part are designed with spherical surfaces that enable smooth pivoting and rotation during assembly and disassembly. This spheroidality allows the components to move freely in multiple directions, providing flexibility in the assembly process and accommodating variations in implant placement angles without requiring high precision alignment.

Function Achieved in This Case
Enables patients to experience a fixed denture sensation while allowing easy conversion to a removable state for cleaning and maintenance, enhancing flexibility and ease of use without requiring professional assistance.
Implementation Method 1
the inner part can be snapped into the outer part in the manner of a push-button or locking connection with elastic deformation of the inner part and/or the outer part

AI summary
The invention relates to a dental anchoring system for anchoring a carrier element (3) to an anchoring element (9), comprising at least the carrier element (3), the anchoring element (9) and a fastening screw (4), wherein the anchoring element (9) has a receiving portion (1) for receiving the carrier element (3) and a threaded bore (10), the carrier element (3) is designed for direct or indirect fastening to a dental structural element, in particular to a dental prosthesis, and forms a bearing portion (12) for bearing on the receiving portion (1) of the anchoring element (9), the carrier element (3) can be fastened on the anchoring element (9) in a first anchoring type (100) using the fastening screw (4) as a result of the fact that the carrier element (3), by means of the bearing portion (12) thereof, is received on the receiving portion (1) of the anchoring element (9) and the fastening screw (4) is screwed into the threaded bore (10) of the anchoring element (9). According to the invention, the carrier element (3) can also be optionally detachably fastened to the anchoring element (9) by means of a second anchoring type (200) without using the fastening screw (4).
