Resilient Dental Separating Ring with Spearheaded Wedge Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional separating rings for dental restoration require significant force to keep open and skilled maneuvering to insert legs between teeth, leading to potential placement errors and increased surgery time, and managing various wedge sizes complicates the process.
Innovation Solution
An integrated separating ring with a resilient, bent open ring body featuring flat-spearheaded wedge legs that easily fit between adjacent teeth, reducing the need for multiple wedge sizes and simplifying the insertion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional separating ring with perpendicular legs is used, then matrix can be held in position, but requires considerable force to keep open and great skill to insert legs between teeth
Solution Approach 1:
The separating ring is divided into functional segments: the resilient body provides separation force, while the wedge legs provide insertion and positioning functions. This segmentation allows each part to optimize its specific function independently.
Solution Approach 2:
Instead of having the legs forced together to press the matrix (conventional approach), the invention uses the resilient body to force the legs apart, creating a spreading action that eases insertion while maintaining matrix positioning through the wedge shape.
2Reliability
If conventional separating ring is used, then teeth can be separated, but increases surgery time and may lead to placement errors
Solution Approach 1:
The separating ring incorporates a resilient body that dynamically adapts to the tooth structure during insertion, automatically adjusting to maintain separation force while reducing the manual manipulation time required by the dentist.
Solution Approach 2:
The resilient body automatically provides the separation force needed to maintain tooth isolation without requiring continuous manual intervention, allowing the dentist to focus on the restorative procedure rather than maintaining ring tension.
3Adaptability or versatility
If multiple wedge sizes are used, then correct wedge can be selected for different teeth, but storing and managing numerous wedges becomes a burden
Solution Approach 1:
The separating ring integrates multiple functions into a single device: the resilient body provides separation force, the wedge legs provide insertion capability, and the integrated design eliminates the need for separate wedge instruments, allowing one tool to perform what previously required multiple specialized instruments.
