Dental Fit Checking Material Consistency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fit checking materials for dental use are not efficient for facilitating fitting checks due to issues related to consistency and ease of application.
Innovation Solution
A fit checking material composition comprising a first paste and a second paste, mixed to achieve a consistency of 37 mm or greater and 43 mm or less, which inhibits free flowing and ensures uniform spreading on the inner surface of dental prostheses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the fit checking material is applied to check the fit of dental prosthesis, then the fit can be determined, but the material flows freely on the inner surface making uniform spreading difficult
Solution Approach 1:
The patent changes the consistency parameter of the fit checking material by controlling the mixing time and temperature to achieve a specific viscosity range (37-43 mm at 35 seconds mixing time at 23°C). This parameter control prevents excessive flow while enabling uniform spreading on the prosthesis inner surface, resolving the contradiction between measurement precision and ease of operation.
2Ease of operation
If the material consistency is too low, then it spreads easily, but it flows freely and cannot be controlled on the prosthesis surface
Solution Approach 1:
The patent optimizes the consistency parameter through controlled mixing (35 seconds at 23°C) to achieve a balanced viscosity that enables both easy spreading and uniform distribution. The specific consistency range (37-43 mm) ensures the material spreads uniformly without excessive flow, resolving the contradiction between ease of spreading and uniformity of distribution.
3Reliability
If the material is highly viscous, then it resists flowing, but it becomes difficult to apply and spread
Solution Approach 1:
The patent adjusts the viscosity parameter through controlled mixing time (35 seconds) and temperature (23°C) to achieve an optimal consistency range (37-43 mm). This range provides sufficient flow resistance to prevent uncontrolled spreading while maintaining ease of application, resolving the contradiction between flow control and ease of application.
