Solution Overview

Problem

Existing dental implantology techniques face challenges in achieving precise alignment and angulation between dental implants and prostheses, particularly when the required angulation exceeds 0° to 45°, which standard abutments cannot adequately address.

Innovation Solution

A transepithelial abutment composed of 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 hollow space defined by two axes to accommodate different inclinations, ensuring a secure and integral connection to the implant.

Engineering Contradictions & Design Principles

VSEngineering 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 inclination is limited

Engineering Contradiction:
Improveability to correct implant closure positionVSAvoidabutment structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The abutment is divided into two separate bodies: a upper body that receives the prosthesis and a lower body that connects to the implant. This segmentation allows each body to be optimized for its specific function and enables the lower body to be angled relative to the upper body, providing correction of implant closure position while maintaining functional simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lower body is designed with a different orientation angle relative to the upper body, introducing angular dimensionality to the abutment structure. This allows the abutment to correct both vertical and angular closure positions of the implant, transforming a single-axis connection into a multi-axis adjustment system.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If angled abutments are manufactured in standard ways, then production is efficient, but they cannot solve all drawbacks in implant rehabilitations requiring different angulations

Engineering Contradiction:
Improverange of angulationsVSAvoidcustomization requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The lower body is designed as a universal component that can be manufactured in standard angle configurations (0°, 5°, 15°, 30°, 45°). Each lower body variant maintains the same basic structure and connection interfaces, allowing a single design family to serve multiple angulation requirements through standardized manufacturing processes.

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

3Adaptability or versatility

If the lower body has a hollow space defined by two axes, then different inclinations can be accommodated, but the device complexity increases

Engineering Contradiction:
Improveaccommodation of different inclinationsVSAvoidhollow space configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The upper body is positioned within and connected to the lower body through the hollow space structure. The hollow space of the lower body accommodates the upper body, creating a nested configuration that allows angular adjustment while maintaining a compact integrated structure.

Inventive Principle:
Principle #7Nested doll (Nesting)
