Dental Implant Root Assembly with Visual Position Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional root assemblies face challenges in ensuring precise and firm engagement between the positioning device and the implant body due to shading by gum tissue and reliance on subjective dentist experience, leading to potential slanting and instability, which can result in loose artificial teeth.
Innovation Solution
Incorporation of a first recognition portion on the positioning seat and a second recognition portion on the positioning unit, allowing for visual and precise alignment during screwing operations, preventing undue tight screwing and ensuring stable attachment by marking the end edge of the positioning hole, thereby preventing loose artificial teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the positioning device is attached based on dentist's subjective sensation and experience, then the operation is simple and quick, but the positioning accuracy and stability deteriorate leading to slanting and loose artificial teeth
Solution Approach 1:
The patent uses visual indicators (color changes or distinct markings) on the positioning device and implant body to provide objective feedback during the attachment operation. The dentist can visually confirm proper positioning through these indicators rather than relying on subjective sensation, thereby improving positioning accuracy while maintaining operational simplicity.
Solution Approach 2:
The patent incorporates feedback mechanisms in the form of visual indicators that provide real-time information about the positioning state. The indicators show whether the positioning device is correctly aligned and seated on the implant body, allowing the dentist to adjust if necessary and ensuring accurate positioning without complex procedures.
2Stability of the object's composition
If the positioning device is screwed tightly to ensure firm attachment, then the stability improves, but the risk of rubbing and damage between components increases
Solution Approach 1:
The patent uses visual indicators to show the correct positioning and engagement state before final tightening. This preliminary visual confirmation ensures that the positioning device is properly aligned and will engage correctly during tightening, preventing rubbing and damage while achieving stable attachment.
Solution Approach 2:
The patent replaces reliance on mechanical sensation (dentist's subjective feeling during tightening) with visual indicators that show when proper engagement is achieved. This substitution allows for controlled tightening based on visual feedback rather than force application, preventing component damage while ensuring stability.
3Strength
If the positioning device is loosely attached to avoid component damage, then the component integrity is preserved, but the positioning stability deteriorates leading to slanting and loose artificial teeth
Solution Approach 1:
The visual indicators provide real-time feedback during the attachment process, showing when the positioning device is correctly positioned and engaged. This feedback allows the dentist to apply appropriate tightening force to achieve stable positioning without over-tightening, thus maintaining both component integrity and positioning stability.
4Loss of time
If the screwing operation is stopped based on dentist's subjective determination, then the operation time is reduced, but the positioning precision deteriorates due to shading by gum tissue
Solution Approach 1:
The patent uses visual indicators that remain visible and provide clear positioning information despite gum tissue shading. These indicators allow the dentist to quickly and accurately determine when proper positioning is achieved without prolonged operation, maintaining both time efficiency and positioning precision.

AI summary
A root assembly (3) includes an implant body (31) and a positioning device (32) connected to the implant body (31). The implant body (31) has a positioning hole (312) formed through one end thereof and an engaging portion (311) opposite to the positioning hole (312). The positioning hole (312) has an end edge. The positioning device (32) has a positioning seat (321) where an artificial tooth (4) is attached and a positioning unit (322) extending through and out of the positioning seat (321). A first recognition portion (3211) is formed on the positioning seat (321). The location of the first recognition portion (3211) of the positioning seat (321) corresponding to the end edge of the positioning hole (312) can recognize that the positioning device (32) is exactly positioned on the implant body (31), thereby preventing the positioning device (32) from loosening.
