Magnetic Occlusal Plane Analyzer for Dental Prosthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing occlusal plane analyzers are cumbersome and difficult to operate, as they require precise adjustment of the jaw model and rotation center positioning, making it challenging to accurately draw and determine occlusal planes, especially for multiple teeth alignment.
Innovation Solution
An occlusal plane analyzer featuring a magnetic analysis board with a circular support hole and a Monson curve imparting tool, comprising a spherical body section and an extended section, which allows for easy positioning and drawing of occlusal planes by sliding and swinging the tool to center the occlusal plane analysis point, facilitating accurate alignment of teeth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional Broadrick occlusal plane analyzer with compass is used, then occlusal plane can be drawn, but the fulcrum of the compass shifts during drawing requiring careful operation
Solution Approach 1:
A magnetic board is introduced as an intermediary between the compass and the drawing surface. The magnetic board contains embedded magnets that guide the compass fulcrum to maintain a fixed position during drawing, preventing shift and ensuring accuracy while simplifying operation.
Solution Approach 2:
The traditional purely mechanical compass system is replaced by a hybrid system incorporating magnetic fields. The magnetic attraction force substitutes for mechanical friction and operator skill in maintaining fulcrum stability, enabling more reliable and easier operation.
2Measurement precision
If traditional occlusal plane analyzer showing only one point is used, then a single occlusal plane analysis point can be determined, but it is not possible to intuitively check whether a plurality of teeth are arranged on the correct occlusal plane
Solution Approach 1:
The analysis transitions from a single-point (0D) measurement to a multi-point spatial distribution (3D) visualization. By determining and displaying multiple occlusal plane analysis points corresponding to different teeth simultaneously, the system enables intuitive verification of teeth arrangement on the occlusal plane across multiple dimensions.
Solution Approach 2:
The occlusal plane analyzer is enhanced to perform multiple functions: it not only determines individual occlusal plane analysis points but also collectively evaluates the arrangement of multiple teeth. This multi-functional capability allows simultaneous assessment of various teeth positions relative to the occlusal plane.
3Manufacturing precision
If occlusal plane analyzers requiring adjustment of fixed position and rod position are used, then rotation center can be positioned at 4 inches from reference points, but the adjusting work is not easily achieved
Solution Approach 1:
The system performs self-positioning through magnetic attraction. The magnetic board automatically guides the compass fulcrum to the correct position based on embedded magnetic field patterns, eliminating the need for manual adjustment of fixed positions and rod positions while maintaining precise rotation center placement.
Solution Approach 2:
The magnetic board is pre-configured with embedded magnets positioned at specific locations corresponding to reference points. This preliminary arrangement of magnetic fields prepares the system in advance to automatically guide the compass to the correct 4-inch radius position without requiring operator adjustment during use.
