Try-In Denture Base With Movable Tooth Receptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wax-up models for dentures lack stability and are prone to accidental amendments, especially in high temperatures, requiring multiple adjustment cycles to achieve a proper fit with the patient's anatomy.
Innovation Solution
A try-in denture base with a first reception that allows for a relative movement of artificial teeth, made from a material with higher hardness like plastic, providing a continuous open space for adjustment and stability, and using positioning elements to facilitate precise positioning and orientation of teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wax-up model is used for try-in denture, then the model is easily adjustable to patient's anatomy, but the model lacks stability and is prone to accidental amendments especially in high temperatures
Solution Approach 1:
The denture base is divided into multiple reception areas (first reception, second reception, third reception) that can independently receive and adjust different sets of artificial teeth. Each reception contains positioning elements that can be selectively adjusted, allowing localized modifications without affecting the entire denture structure, thus maintaining stability while enabling adjustability.
Solution Approach 2:
Positioning elements serve as intermediaries between the denture base and artificial teeth. These positioning elements can be adjusted in position and orientation within the reception areas, mediating the relationship between the fixed base structure and the adjustable teeth, thereby resolving the contradiction between base stability and tooth position flexibility.
2Ease of operation
If a wax-up model is used for try-in denture, then adjustments can be made during try-in, but accidental amendments occur requiring additional adjustment cycles
Solution Approach 1:
The positioning elements are pre-configured within the reception areas with defined positions and orientations before the actual try-in process. This preliminary arrangement allows the dentist to make controlled, intentional adjustments during try-in without the risk of accidental amendments, as the rigid base structure with predetermined positioning elements prevents unintended changes.
Solution Approach 2:
The positioning elements are designed to be adjustable within the reception areas during the try-in phase, allowing dynamic modification of tooth positions and orientations. After the optimal configuration is achieved, the structure maintains its form, preventing further accidental changes, thus reducing the need for additional adjustment cycles.
3Adaptability or versatility
If the reception volume is larger than the combination of basal volumes of artificial teeth, then relative movement of teeth is enabled, but the space utilization is reduced
Solution Approach 1:
The reception areas are designed with larger volumes than the artificial teeth they receive, creating localized spaces that allow for positional adjustments. This local excess space is concentrated only where needed for adjustment purposes, rather than uniformly distributed, thus enabling movement freedom in critical areas while maintaining efficient space utilization in the overall denture base structure.

AI summary
The invention relates to a try-in denture base comprising one or more receptions for receiving basal sections of artificial teeth. A first reception is configured to receive two or more basal sections of two or more artificial teeth. A reception volume provided by the first reception is larger than a combination of basal volumes of the two or more basal sections of the two or more artificial teeth to be received. The first reception forms a continuous open space configured to enable a relative movement of the two or more basal sections of the two or more artificial teeth within the first reception towards and away from each other.
