Solution Overview

Problem

Existing dental implantology techniques face challenges in achieving precise and comfortable prosthesis attachment with angulation divergences between 0° and 60°, particularly in cases where bone structure and implant positioning result in inclined positions, making standard abutments inadequate for various anatomical situations.

Innovation Solution

A straight transepithelial abutment with an internal connection and multiple gingival heights, designed for biocompatible materials, allowing angulation divergences between 0° and 60°, featuring a beveled surface for improved contact and a threaded structure for secure attachment to dental implants, accommodating various prostheses and single crowns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If standard abutments are used, then the attachment between implant and prosthesis is achieved, but the angulation divergences between 0° and 60° cannot be properly addressed

Engineering Contradiction:
Improveangulation adaptationVSAvoidattachment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The abutment incorporates an adjustable angulation mechanism that allows changing the orientation parameter from 0° to 60° relative to the implant axis. This enables the same abutment to adapt to various bone structures and implant positions while maintaining precise attachment through controlled parameter adjustment.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The abutment transitions from a fixed standard design to a dynamic adjustable design where the angulation can be modified after implantation. This dynamic capability allows clinicians to optimize the prosthesis orientation according to the actual anatomical conditions without requiring multiple pre-fabricated abutment types.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple standard abutments for different angulations are manufactured, then all angulation cases can be covered, but the device complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improveangulation coverageVSAvoidabutment variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single universal abutment design incorporates an adjustable angulation mechanism that replaces the need for multiple specialized abutments. This multi-functional device can be configured for any angulation from 0° to 60°, simplifying the system while expanding its applicability to all clinical scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The abutment is divided into modular components including an implant interface portion, an adjustable angulation mechanism, and a prosthesis attachment portion. This segmentation allows independent adjustment of the angulation parameter without affecting other functional aspects, enabling versatile application with a single device type.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If the abutment design is simplified for easy manufacture, then production cost decreases, but the ability to accommodate diverse angulations is reduced

Engineering Contradiction:
Improveabutment fabricationVSAvoidprosthesis orientation
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The abutment incorporates pre-configured adjustment mechanisms and guide features that enable clinicians to set the desired angulation during the procedure. These preliminary structural preparations allow complex angular adjustments to be made through simple rotational movements rather than requiring complex manufacturing processes.

Inventive Principle:
Principle #10Preliminary action
