Artificial Tooth Bonding Aid for Precise Occlusal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in producing dentures with artificial teeth is the difficulty in achieving precise positioning due to the mobility of teeth in the gingiva during adhesive hardening, which can lead to inadequate occlusal properties and potential need for rework.
Innovation Solution
A bonding aid device comprising an occlusion device, support device, and clamping element that aligns and fixes teeth in predefined positions using pressure, ensuring stable support and precise occlusion before adhesive hardening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gingival receptacles have play for tooth insertion, then the teeth can be inserted into the gingiva with adhesive, but the teeth become mobile during adhesive hardening making exact positioning difficult
Solution Approach 1:
The bonding aid device is assembled and teeth are positioned in the occlusion device before adhesive application. The clamping element is prepared to apply pressure during curing, preventing displacement before the adhesive hardens, thus ensuring precise positioning from the start.
Solution Approach 2:
The bonding aid device acts as an intermediary tool between the teeth and the gingiva during the bonding process. It provides a stable reference framework that mediates the positioning of teeth, allowing precise placement while the adhesive cures, and then can be removed after bonding is complete.
2Manufacturing precision
If teeth are fixed in position during adhesive hardening, then exact positioning is maintained, but the process becomes more complex requiring additional bonding aid devices
Solution Approach 1:
The bonding aid device is divided into separate components: an occlusion device with tooth impressions, a support device with support elements, and a clamping element. These segmented parts can be independently prepared and assembled, making the device easier to manufacture and adjust while still providing stable positioning during bonding.
Solution Approach 2:
The bonding aid device transitions from a rigid positioning framework during assembly to a controlled pressure application state during curing. The clamping element provides dynamic pressure that adapts to maintain positioning precision throughout the adhesive hardening process, then allows easy removal after bonding.
3Stability of the object's composition
If pressure is applied to fix teeth during curing, then displacement is prevented, but the adhesive distribution must be carefully controlled
Solution Approach 1:
The support elements are positioned at specific locations on the support device to provide localized support to the gingiva. This local quality approach allows pressure to be applied at precise points, stabilizing tooth positions while controlling adhesive distribution in specific areas, preventing both displacement and excessive adhesive extrusion.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise alignment and fixation of teeth during the curing process, preventing displacement and allowing for real-time correction of positioning issues, thereby reducing the need for rework and ensuring satisfactory occlusal properties.
Implementation Method 1
The clamping element is configured to apply pressure to a second side of the occlusion device facing away from the first side and to a second side of the support device facing away from the first side
