Dental Implant Abutment Joint Assembly with Angled Threaded Bores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant abutment systems face challenges in achieving proper alignment due to the need for parallel implant placement, which is not always feasible, leading to misalignment and reduced effectiveness in mounting dental appliances.
Innovation Solution
A joint assembly for dental implant abutment featuring a base member with angled threaded bores and a ball section that allows for selective angular orientation, enabling proper alignment and secure attachment of dental appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If implants are placed parallel to each other for proper alignment, then mounting effectiveness is improved, but implant placement feasibility deteriorates due to bone availability constraints
Solution Approach 1:
The ball section is made selectively mountable at different angular orientations (e.g., 0°, 45°, 90°) relative to the abutment section, allowing the system to adapt dynamically to various implant positions. This enables the mounting cap to be oriented properly even when implants are placed at divergent angles due to bone constraints.
Solution Approach 2:
The invention changes the angular parameter of the ball section's orientation by providing multiple threaded bores at different angles. This allows adjustment of the mounting angle to match the implant orientation, resolving the contradiction between maintaining parallel alignment for effectiveness and adapting to divergent placements for feasibility.
2Adaptability or versatility
If implants are tilted to accommodate bone availability, then implant placement feasibility is improved, but alignment precision deteriorates leading to mounting misalignment
Solution Approach 1:
The ball section's selective angular mounting capability allows the system to compensate for implant tilting. Even when implants are placed at non-parallel angles to accommodate bone availability, the ball section can be oriented at the appropriate angle to achieve proper alignment with the mounting socket.
Solution Approach 2:
The invention adds an angular dimension to the mounting system by providing threaded bores at multiple angles (0°, 45°, 90°). This additional degree of freedom allows adjustment in the angular dimension to compensate for misalignment caused by implant tilting in the spatial dimensions.
3Device complexity
If a fixed alignment system is used, then structural simplicity is improved, but adaptability to divergent implant orientations deteriorates
Solution Approach 1:
The mounting system is segmented into an abutment section and a ball section that can be independently oriented. The ball section can be selectively mounted at different angles, providing adaptability without requiring a completely complex adjustable mechanism. Each segment maintains relative simplicity while the combination provides versatility.

AI summary
The joint assembly for dental implant abutment includes an abutment section adapted for attachment to a dental implant and a ball section selectively mounted to the abutment section at a user-selectable angle. The abutment section includes a base member having a recessed socket. A plurality of threaded bores radiate into the base member from the socket. The ball section includes a spherical head having a threaded post extending therefrom for mounting the ball joint into a user-selectable threaded bore in the socket to properly orient an integral locator mounting cap retained on the spherical head for attachment of a denture to the joint assembly. The angular orientation of the threaded bores allows a restorative dentist to adjust the joint assembly for effective mounting of the denture or other dental appliance.
