Solution Overview

Problem

Conventional dental abutments lack versatility and do not provide adequate support for dental prostheses, leading to hygiene maintenance issues with fixed prostheses and limitations in fit and securement, especially with straight abutments and removable prosthesis systems.

Innovation Solution

An angled abutment system that allows for retrievability by patients or dentists, offering different retention levels and support for various types of dentures, including fixed and removable options, with a non-engaging or engaging connection to dental implants, and featuring screw threads or retentive inserts for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a straight abutment is used to secure a dental prosthesis, then the retention and support are provided, but the versatility and fit for different implant positions are limited

Engineering Contradiction:
ImproveversatilityVSAvoidabutment design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The abutment incorporates a universal connection mechanism that allows dynamic adjustment of the prosthesis angle and position. The retention cap and retaining device enable the prosthesis to be secured at multiple angles rather than a fixed straight alignment, providing adaptability to different implant positions while maintaining a relatively simple abutment base design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The dental prosthesis system is divided into separate components: the abutment body, retention cap, retaining device, and prosthesis. This segmentation allows each component to be optimized independently - the abutment provides structural support while the retention mechanism provides adjustable connectivity, resolving the contradiction between versatility and complexity.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a fixed prosthesis is used to provide strong support, then the retention is improved, but the hygiene maintenance becomes difficult

Engineering Contradiction:
Improveprosthesis supportVSAvoidhygiene maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The prosthesis is designed with dynamic retrievability through the retention cap mechanism. Patients can easily remove and reattach their prostheses themselves using simple twisting motions, transforming a static fixed prosthesis into a dynamically adjustable one that maintains strong support when attached but enables easy hygiene maintenance when removed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The retention cap and retaining device are designed to enable patients to perform their own prosthesis removal and reattachment without dental professional intervention. This self-service capability allows patients to maintain hygiene by removing prostheses for cleaning while still receiving strong support when the prostheses are properly attached.

Inventive Principle:
Principle #25Self-service

3Shape

If the prosthesis junction is positioned above the smile line for maxillary fixed dentures, then the aesthetic appearance is improved, but the bone removal becomes aggressive

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidbone removal aggression
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The universal connection abutment allows the prosthesis to be positioned at optimized angles that may not require aggressive bone removal to achieve aesthetic positioning above the smile line. The adjustable orientation capability enables the prosthesis to be angled optimally for aesthetics while the implant can be placed in a more conservative position regarding bone structure.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If a removable prosthesis system is used to allow patient retrieval, then the ease of operation is improved, but the support and retention levels are reduced

Engineering Contradiction:
ImproveretrievabilityVSAvoidprosthesis support
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The retention cap incorporates a spherical or rounded engagement surface that interfaces with the retaining device. This curved geometry provides large surface area contact and mechanical interlocking that delivers strong retention forces while still allowing easy rotational removal by the patient, thus maintaining both strong support and ease of operation.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A dental anchoring system includes an angled abutment, having a main body extending from a top to a channel body, the channel body extending away from the main body at a predetermined angle less than 180 degrees; a lip extending around the top; and an opening extending from the top and through the channel body, the opening to receive an attachment device; the angled abutment is to provide an angled attachment for a dental prosthetic.
