Dental Superstructure Attachment System with Curved Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental superstructure attaching systems face challenges in securely attaching a superstructure to dental implants at varying angles without visible attachment means, requiring complex assembly and specialized tools, and often result in poor hygiene interfaces and cumbersome installation processes.
Innovation Solution
A two-part superstructure attachment system featuring a longitudinal member with a curved interface area and a casing that allows angular displacement and secure clamping to the implant, using a screw for attachment, enabling a standard screw connection and improved fit between the system and superstructure, while allowing for various material options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate angled distances are used to accommodate varying implant positions and angles, then the system can adapt to different patients, but the device complexity increases and the mounting process becomes cumbersome
Solution Approach 1:
The attachment system employs a universal base component that can accommodate multiple implant angles (0°, 15°, 30°, 45°, 60°) through a single multi-functional design. The base includes multiple receptacles arranged at different angles, allowing one component to replace what would traditionally require multiple separate angled distances, thereby reducing device complexity while maintaining adaptability.
2Reliability
If conventional attachment methods with visible screws or cement are used, then the superstructure can be securely attached, but the aesthetic appearance is compromised
Solution Approach 1:
The invention extracts the attachment mechanism from the visible oral surface by placing all fastening components (screws, receptacles, and connection interfaces) entirely subgingivally beneath the gum line. The superstructure attaches to the base through hidden interfaces, eliminating any visible screws or cement from the aesthetic zone while maintaining secure attachment through the subgingival connection system.
3Manufacturing precision
If multiple different distances must be tested to find the correct match, then the correct angle can be achieved, but the loss of time during the procedure increases
Solution Approach 1:
The base component is pre-manufactured with receptacles positioned at predetermined standard angles (0°, 15°, 30°, 45°, 60°). During the procedure, the practitioner simply selects the appropriate receptacle based on the required angle rather than testing multiple distances, significantly reducing procedure time while maintaining precise angle matching capability.

AI summary
A dental superstructure attaching system for use with a dental implant is provided. The system comprises a longitudinal member being connectable with an implant or an implant connecting member via an at least partially curved interface area. The longitudinal member comprises a main member forming the lingual part of said longitudinal member, and a lever member forming the buccal or labial part of said longitudinal member. The longitudinal member further comprises means for urging said lever member and said main member away from each other, such that said longitudinal member is secured to said implant or implant connecting member. The system further comprises a casing (200) for attachment to a dental superstructure on the outer surface of the casing (200), said casing (200) comprising a cavity (201) for housing the longitudinal member (102), such that when urging said lever member (102b) and said main member (102a) away from each other, the longitudinal member (102) is secured in said cavity (201). Methods for attaching a dental superstructure to a dental implant via such a system, are also provided.
