Angular Dental Implant Mounting System for Prosthetic Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental implant systems face challenges in aligning prosthetic structures with the jaw bone due to misalignment between the implant and adjacent teeth, leading to weak connections or misaligned prosthetics, especially in confined spaces and when using angled abutments that are not suitable for all applications.
Innovation Solution
An angularly adjustable dental implant abutment mounting system with a transmucosal collar, fixation screw, and mounting head that allows for selective orientation of the abutment axis relative to the implant axis, using a system of transmucosal collars and mounting heads with standardized attachment methods to accommodate various dental applications and implant types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dental implant is inserted into the jaw bone with central axis boreholes for technical reasons, then the implant can be securely fixed in the jaw bone, but the longitudinal direction of the implant cannot be aligned with adjacent teeth, causing misalignment between the implant and prosthetic structure
Solution Approach 1:
The mounting system is divided into separate functional components: an implant portion for secure fixation in the jaw bone, a transmucosal collar for transition, and a mounting head for prosthetic attachment. This segmentation allows each component to optimize its specific function independently, resolving the contradiction between secure fixation and alignment precision.
Solution Approach 2:
The transmucosal collar acts as an intermediary element between the implant and the mounting head, providing angular adjustment capability. This intermediary component allows the mounting head to be positioned at optimal angles relative to the implant, compensating for the misalignment caused by the implant's fixed orientation in the jaw bone.
2Manufacturing precision
If angled abutments are used to compensate for implant angulation, then alignment with adjacent teeth is improved, but the system becomes unsuitable for applications with restricted lateral working space
Solution Approach 1:
The mounting head incorporates an angular adjustment mechanism that allows dynamic repositioning of the abutment relative to the implant. This dynamic capability enables the system to adapt to various spatial constraints and dental applications, maintaining alignment precision while expanding versatility to include restricted working space scenarios.
Solution Approach 2:
The standardized mounting system with adjustable components can be applied across multiple dental scenarios including single tooth replacements, multi-tooth bridges, and overdentures. The universal design with angular adjustment resolves the contradiction by providing a single system that achieves precise alignment across diverse applications with varying spatial requirements.
3Manufacturing precision
If a ball and socket joint is used to allow angular adjustment, then misalignment compensation is achieved, but the joint may become unlocked under biting stress or during prosthetic structure attachment
Solution Approach 1:
The patent replaces the traditional ball and socket joint mechanism with a threaded connection system between the transmucosal collar and mounting head. This mechanical substitution provides angular adjustment during installation while eliminating the unlocking problem under functional loads, as the threaded connection maintains stable locking during biting stress and prosthetic attachment operations.
4Reliability
If the prosthetic structure is permanently cemented onto the attachment base, then the connection is secured, but the joint locking screw becomes inaccessible for maintenance or correction
Solution Approach 1:
The system is segmented into removable components including the mounting head and transmucosal collar that can be detached without damaging the implant or requiring complex procedures. This segmentation allows maintenance or correction by simply removing the mounting head, providing easy accessibility to the joint locking screw and other components while maintaining strong connection during normal use.
Solution Approach 2:
The design incorporates a removable mounting head with a through-bore that allows the joint locking screw to remain accessible from the external side. This preliminary design consideration ensures that maintenance or correction procedures can be performed easily by removing the mounting head, eliminating the need for complex surgical exposure or damage to achieve accessibility.

AI summary
Dental implant systems, components and methods feature use of a mounting component onto which an abutment is to be cast or soldered. The mounting component is configured with an upper end that is contoured in a spherical or other suitable manner to present a surface over which the abutment can be slid into various positions on said surface at various angles relative to an axis of the implant body on which the mounting component is supported. Accordingly, the abutment can be set at a desired angle whether the this desired orientation matches or misaligns with the axis of the implant body.
