Position Fixing Device for Dental Models Using Coordinate Markings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The optimal alignment and positioning of upper and lower jaw dentures in dental procedures, both analog and digital, are challenging due to inaccuracies and errors in the alignment process, which affect the precision of dental work and require multiple steps for correction.
Innovation Solution
A position fixing device with positioning means and position markings that interact with a base surface and fixing elements, allowing for precise and stable alignment of dental impressions or models by fixing them to a zero point coordinate origin, enabling precise horizontal and vertical alignment and reducing post-processing adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional alignment methods are used for dental impressions, then the process can be completed with basic equipment, but alignment accuracy deteriorates leading to multiple correction steps
Solution Approach 1:
The patent applies preliminary action by pre-defining a coordinate system and positioning references directly on the dental impression tray and articulator before the actual alignment process. Position markings are created during impression taking, and a coordinate origin is established in advance on the articulator base, enabling accurate positioning without complex real-time measurements or multiple correction iterations.
2Measurement precision
If multiple correction steps are performed to achieve proper occlusion, then alignment accuracy can be improved, but time consumption and process complexity increase
Solution Approach 1:
The patent performs preliminary positioning by establishing a coordinate system and positioning references during the initial impression taking phase. Position markings are created beforehand on the impression tray, and the coordinate origin is pre-established on the articulator, allowing direct accurate positioning in a single step rather than requiring multiple iterative corrections.
Solution Approach 2:
The patent replaces complex mechanical alignment procedures with a coordinate-based positioning system. Instead of relying on manual mechanical adjustment and trial-and-error fitting, the invention uses defined coordinate origins, position markings, and reference points that can be precisely located and measured, substituting mechanical complexity with a systematic coordinate approach.
3Loss of information
If digital impression technology is used, then real-time feedback is improved, but equipment cost and system complexity increase
Solution Approach 1:
The patent segments the positioning system into distinct, simple components: position markings on the impression tray, a coordinate origin on the articulator base, and reference points. This segmentation allows the complex positioning task to be broken down into manageable elements that can be implemented with simple equipment rather than requiring complex integrated digital systems.
Solution Approach 2:
The patent introduces position markings and coordinate references as intermediary elements between the digital impression data and the physical articulator setup. These intermediaries serve as common reference points that bridge the digital and physical domains, enabling accurate positioning without requiring complex direct integration between digital imaging systems and articulators.
