Intraoral Scanner Bubble Level Head Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intraoral scanners lack sufficient information for complex oral rehabilitation and clear aligner systems, as they fail to accurately capture the natural head position and three-dimensional orientation of the occlusal plane, relying on analogue methods and manual operator interpretation for digital articulator mounting.
Innovation Solution
An intraoral scanner equipped with a bubble level, either analogue or digital, for precise orthogonal alignment, combined with a data acquisition protocol that includes scanning the maxillary arches, natural head position, and facial aesthetic references, ensuring accurate transfer to digital articulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current intraoral scanners are used for scanning, then the basic dental structures can be captured, but the natural head position and three-dimensional occlusal plane orientation cannot be accurately acquired
Solution Approach 1:
The patent combines the intraoral scanner with a bubble level device into a single integrated system. The bubble level is mechanically coupled to the scanner housing, allowing simultaneous acquisition of dental impressions and head position data without requiring separate devices or manual positioning procedures.
Solution Approach 2:
The intraoral scanner is enhanced with multi-functionality by incorporating the bubble level, enabling it to perform both traditional dental scanning and head position/orientation measurement. This eliminates the need for separate analogue positioning systems and integrates multiple functions into one device.
2Loss of information
If analogue systems such as Face Arch and Plane System are used, then functional elements and spatial position information can be obtained, but the workflow becomes time-consuming and requires manual operator interpretation
Solution Approach 1:
The patent replaces manual mechanical positioning systems (Face Arch, Plane System) with an automated digital system. The bubble level provides automatic gravitational reference, and the scanner digitally captures all position data, eliminating manual operator interpretation and reducing procedure time.
Solution Approach 2:
The system performs self-positioning using the bubble level's automatic gravitational reference. The device autonomously determines the orthogonal position relative to the patient's head without requiring manual adjustment or operator skill for positioning, enabling consistent and rapid data acquisition.
3Ease of operation
If digital prints are transferred to screen in horizontal position, then digital workflow is simplified, but the three-dimensional spatial position present in the patient is not represented
Solution Approach 1:
The system uses the bubble level data to provide feedback about the patient's actual head position and orientation. This information is used to transform and orient the digital dental impressions in three-dimensional space, ensuring accurate spatial representation while maintaining digital workflow efficiency.
