Transepithelial Abutment With Captive Screw for 0°–45° Angulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental implant systems face challenges in achieving precise alignment and angulation between dental implants and prostheses, particularly in cases where the required angulation exceeds 0°, especially between 0° and 45°, which standard abutments cannot adequately address.
Innovation Solution
A transepithelial abutment comprising three components - an upper body, a lower body, and a captive screw - that allows for angulations between 0° and 45°, with the lower body having a non-straight hollow space defined by two axes, ensuring a secure and integral connection to the implant, and supporting various dental structures through a planar surface with constant dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard abutments are used for dental implants, then the implant-prosthesis connection is simple, but the ability to correct implant closure position in height and angulation (0°-45°) is insufficient
Solution Approach 1:
The abutment is divided into multiple segments: a lower body portion that interfaces with the implant, an upper body portion that supports the prosthesis, and an intermediate connection portion. This segmentation allows each part to be optimized for its specific function while collectively providing angulation correction capabilities between 0°-45° without excessive overall complexity.
Solution Approach 2:
The invention introduces angular/rotational dimensionality to the abutment design, enabling it to correct both vertical height and horizontal angulation of the implant-prosthesis connection. The abutment can be positioned at different angles relative to the implant axis, providing multi-dimensional adjustment capability that standard straight abutments lack.
2Adaptability or versatility
If angled abutments are manufactured in standard ways, then production is efficient, but they cannot solve all implant rehabilitation cases with varying angles up to 45°
Solution Approach 1:
The abutment design incorporates variable geometric parameters, particularly in the connection portion geometry, that can be adjusted to accommodate different implant angles. By changing the angular parameters of the abutment body and connection interfaces, the same basic design can be adapted to cover the full 0°-45° range of implant rehabilitation cases.
Solution Approach 2:
The abutment is designed as a universal component that can serve multiple functions: it provides mechanical connection, angular correction, height adjustment, and load distribution. The standardized yet adaptable design allows a single abutment type to handle diverse implant configurations without requiring completely different manufactured solutions for each angle.
3Reliability
If the abutment provides precise alignment and support for prostheses with angulations up to 45°, then the biological closure and load distribution are enhanced, but the device complexity increases
Solution Approach 1:
The abutment system is segmented into distinct functional components that can be separately optimized and assembled. This segmentation allows each component to specialize in a specific aspect of load management or alignment, improving overall reliability while keeping individual component complexity manageable.
Solution Approach 2:
Multiple functional features (angular correction, height adjustment, mechanical retention, and load distribution) are merged into a single integrated abutment assembly. This consolidation provides comprehensive functionality that enhances biological closure and load distribution without requiring multiple separate devices, thereby limiting the increase in overall system complexity.
