Integrated Facebow-Bite Fork Device for Dental Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental procedures for acquiring patient-specific measurements for articulators are time-consuming and require expert handling, with a need for methods and devices that can improve scanning speed and accuracy.
Innovation Solution
A device with a coded pattern is used in dental scanning procedures, featuring an occlusal portion with a bite plate and a non-occlusal portion with a coded pattern. This device is designed to improve scanning time and accuracy by allowing simultaneous scanning of the coded pattern and the patient's teeth, facilitating accurate alignment and spatial relationship determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional facebow and bite fork methods are used to obtain patient-specific measurements, then accurate spatial orientation measurements can be achieved, but the process becomes complicated and time-consuming
Solution Approach 1:
The patent combines the facebow and bite fork into a single integrated device with a unified structure. The bite fork arms are directly connected to the facebow body, eliminating the need for separate components and their respective positioning steps. This merging reduces procedural complexity and time while maintaining measurement accuracy through the integrated reference system.
Solution Approach 2:
The integrated device performs multiple functions simultaneously: it captures spatial orientation data through the facebow component, records bite position through the bite fork component, and provides a unified reference frame for both measurements. This multi-functionality eliminates the need for separate facebow and bite fork procedures, reducing time loss while maintaining precision.
2Manufacturing precision
If facebow and bite fork are mechanically rigidly coupled to the articulator, then accurate mounting of plaster models is achieved, but the process requires expert handling and is complicated
Solution Approach 1:
The integrated facebow-bite fork device is mounted to the articulator as a single unit rather than as separate components. This unified mounting process eliminates the complex coordination required to rigidly couple separate facebow and bite fork components, making the procedure easier to perform while maintaining the precision needed for accurate plaster model positioning.
Solution Approach 2:
The integrated device serves as an intermediary that transfers both facebow spatial orientation data and bite fork occlusion data to the articulator through a single mounting interface. This intermediary function simplifies the operator's task by eliminating the need to separately position and rigidly couple multiple components, while still achieving the required mounting precision.
3Measurement precision
If separate facebow and bite fork procedures are used, then comprehensive patient-specific measurements are obtained, but the device complexity increases
Solution Approach 1:
The patent merges the facebow and bite fork into a single integrated device that captures both spatial orientation and occlusion measurements simultaneously. This consolidation reduces the number of components from two separate devices to one unified structure, simplifying the overall system while maintaining comprehensive measurement capabilities.
Solution Approach 2:
The integrated device performs multiple measurement functions through its unified structure: the facebow portion captures spatial orientation relative to ear canals, while the bite fork portion records occlusion data. This multi-functional design reduces device complexity by eliminating the need for separate facebow and bite fork components while maintaining complete patient-specific measurement capabilities.
