Solution Overview
Problem
Existing dental prosthetic devices face challenges in ensuring parallelism and alignment of abutments, eliminating undercuts, and preventing cement infiltration, which can lead to complications such as detachment and material stress during prosthetic installation.
Innovation Solution
A dental prosthetic device featuring a rotating element with adjustable angles and customizable dimensions, allowing for precise alignment and parallelism of abutments by rotating 0° to 360°, and utilizing mechanical and chemical fixings to secure the abutment to the implant, eliminating undercuts and ensuring stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fixed abutment designs are used, then the structure is simple, but alignment precision and parallelism cannot be guaranteed
Solution Approach 1:
The abutment incorporates a rotating element that can rotate 0° to 360° around a rotation axis, transforming the fixed structure into a dynamic adjustable one. This rotation mechanism enables precise alignment and parallelism adjustment of the abutment relative to the implant, resolving the contradiction between structural simplicity and alignment precision.
Solution Approach 2:
The abutment design allows changing the angular parameter (rotation angle from 0° to 360°) to adjust the alignment and parallelism of the abutment. This parameter adjustment capability enables optimization of the abutment positioning without complicating the basic structural design.
2Reliability
If cementing process is used to fix abutment, then the fixation is achieved, but risk of infiltration and detachment occurs
Solution Approach 1:
The invention extracts and eliminates the cementing process from the abutment fixation system. Instead of relying on cement, the patent employs mechanical fixation methods including the rotating element mechanism and structural engagement features, thereby removing the source of infiltration and detachment risks associated with cement.
Solution Approach 2:
The patent replaces the chemical fixation mechanism (cementing process) with a mechanical fixation system. The rotating element and associated mechanical structures provide secure abutment fixation through physical engagement and controlled rotation, eliminating the harmful effects of cement infiltration and detachment.
3Ease of operation
If implant insertion angle is up to 30° from final position, then easier implant placement is achieved, but undercuts are created
Solution Approach 1:
The invention applies preliminary action by incorporating a rotating element in the abutment design before final assembly. This rotating component allows the abutment to be pre-positioned and adjusted to the correct alignment and parallelism, compensating for any undercut effects and ensuring proper fit without requiring perfect initial implant positioning.
Solution Approach 2:
The rotating element introduces dynamic adjustability to the abutment system, allowing 0° to 360° rotation to correct alignment issues. This dynamic adjustment capability compensates for undercuts created during implant placement, enabling the system to adapt to varying insertion angles while maintaining proper prosthesis alignment.
