Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual bonding of artificial teeth to denture bases is time-consuming and labor-intensive for dental technicians, with quality varying based on their skill level, leading to inconsistent results in plate denture fabrication.
Innovation Solution
A method involving three-dimensional data preparation, denture mold cutting, and integration of artificial teeth within a placement groove, allowing for the simultaneous curing of denture base material with artificial teeth, reducing the need for step-by-step bonding and minimizing technician skill dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual bonding of artificial teeth to denture bases is performed step-by-step, then positioning of artificial teeth can be achieved, but the process requires considerable time and effort especially when the number of artificial teeth is large
Solution Approach 1:
The denture base is divided into multiple regions corresponding to the positions of different artificial teeth. Each region has a recess that can accommodate one or more artificial teeth, allowing simultaneous placement of multiple teeth in one bonding operation rather than bonding them one by one
Solution Approach 2:
The positions of all artificial teeth are predetermined and the recesses are pre-formed in the denture base before bonding. This preliminary arrangement of tooth positions eliminates the need for time-consuming step-by-step positioning during the bonding process, enabling multiple teeth to be bonded simultaneously in their correct positions
2Measurement precision
If dental technicians bond artificial teeth one at a time using adhesives or polymerizable materials, then artificial teeth can be positioned with respect to opposing teeth, but the process requires sophisticated skills and imposes immense burdens on dental technicians
Solution Approach 1:
The denture base is segmented into multiple regions, each with a recess designed to accommodate specific artificial teeth. This segmentation allows multiple teeth to be positioned and bonded simultaneously in their correct locations relative to opposing teeth, eliminating the need for complex step-by-step positioning procedures
Solution Approach 2:
The recesses are pre-formed in the denture base at the correct positions and orientations before the bonding step. This preliminary preparation of tooth positions simplifies the bonding process, as dental technicians only need to place the artificial teeth into the pre-positioned recesses rather than performing sophisticated positioning maneuvers for each tooth individually
3Manufacturing precision
If multiple artificial teeth are bonded sequentially, then each tooth can be positioned correctly, but the fabrication time increases significantly when the number of artificial teeth is large
Solution Approach 1:
The denture base is divided into multiple regions with recesses that can simultaneously accommodate multiple artificial teeth. This allows all artificial teeth to be bonded at the same time in a single operation, dramatically reducing the total bonding time compared to sequential bonding of each tooth individually
Solution Approach 2:
The positions of all artificial teeth are predetermined and the recesses are pre-formed before bonding. This preliminary setup enables multiple teeth to be positioned correctly and bonded simultaneously, eliminating the time-consuming sequential bonding process while maintaining accurate positioning of all teeth relative to opposing teeth
