Artificial Tooth Bonding Fixture for Precise Occlusion Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precise positioning of artificial teeth within an artificial gingiva during the bonding process is challenging due to the mobility of teeth in the gingiva before the bonding agent cures, making it difficult to achieve accurate occlusion and potentially requiring rework or replacement of the dental prosthesis.
Innovation Solution
A bonding auxiliary device comprising an occlusion device, support device, and clamping element that aligns and fixes teeth in predefined positions, ensuring stable support and pressure during the curing process, allowing for precise occlusion setup and correction before the bonding agent hardens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If teeth are placed in receptacles with clearance for bonding agent, then bonding is enabled, but teeth become movable and positioning precision deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-positioning the teeth in the receptacles before the bonding agent is introduced. The teeth are arranged in their final positions while the receptacles still have clearance, allowing for preliminary adjustments. Once positioned, the teeth are fixed in place before bonding, ensuring precision is maintained throughout the bonding process.
Solution Approach 2:
The patent introduces an intermediary element - a support structure or matrix - that temporarily holds the teeth in their correct positions during the bonding process. This intermediary structure prevents teeth movement while allowing the bonding agent to be introduced and cured, resolving the conflict between bonding capability and positioning precision.
2Manufacturing precision
If teeth are fixed firmly in receptacles, then positioning precision is maintained, but bonding agent cannot be properly introduced
Solution Approach 1:
The bonding agent is introduced into the receptacles before the teeth are firmly fixed in their final positions. This preliminary introduction of the bonding agent ensures proper saturation and distribution, while the teeth are then secured in place, maintaining both bonding quality and positioning precision.
Solution Approach 2:
The system transitions from a dynamic state where teeth can move freely in the clearance, to an intermediate state where teeth are partially secured but still adjustable, and finally to a fixed state where teeth are firmly positioned. This dynamic approach allows for optimal bonding agent introduction followed by precise positioning.
3Ease of operation
If teeth are allowed to move during bonding, then bonding agent distribution is improved, but final positioning accuracy deteriorates
Solution Approach 1:
Teeth are pre-positioned in their exact final locations before the bonding agent is introduced. This preliminary positioning ensures that once the bonding agent is distributed, the teeth remain in their correct positions. The system allows for bonding agent distribution while maintaining positional integrity through the use of support structures or matrices.
Solution Approach 2:
The patent uses a matrix or support structure that replicates the exact final positions of the teeth. This copying approach ensures that the teeth are held in their correct positions throughout the bonding process, allowing for proper bonding agent distribution while maintaining positioning accuracy.
Applied Scientific Principles
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 artificial teeth, preventing shifting during curing, facilitating pre-cure checks for positioning errors, and allowing for corrections, thus reducing the need for rework or replacement of dental prostheses.
Implementation Method 1
The clamping element is configured to apply pressure onto a second side of the occlusion device facing away from the first side, and onto a second side of the first support device facing away from the first side, for fixing the first teeth
