Solution Overview
Problem
Current dental technologies lack a precise method for mounting digital dental arch models in virtual articulators, requiring extensive time and training, and fail to accurately relate these models to anatomical points for occlusal plane analysis.
Innovation Solution
A device with a specific design that merges intraoral and extraoral scans, using adjustable parts and high-relief grooves to accurately position dental arch models relative to the Camper plane, allowing precise digitization and integration into dental programs for virtual prosthesis design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital models are mounted in virtual articulators using existing dental programs, then the models can be analyzed for occlusal plane, but the process requires extensive time and specific training to master
Solution Approach 1:
The device incorporates pre-calibrated horizontal rods with fixed anatomical relationships built into their construction. The rods are pre-adjusted to represent accurate inter-arch distances, eliminating the need for operators to perform complex adjustments during the mounting process. This preliminary calibration allows direct transfer of model positions to the virtual articulator without requiring extensive training or time-consuming manual adjustments.
2Manufacturing precision
If existing dental programs are used for mounting models, then virtual prosthesis design can be performed, but the operation is meticulous and demands significant training
Solution Approach 1:
The mounting device serves as a physical intermediary between the scanned dental models and the virtual articulator software. It provides tactile, mechanical guidance through its calibrated rod structure, translating complex 3D spatial relationships into simple physical alignments. This intermediary device bridges the gap between physical models and digital software, making the mounting process intuitive and eliminating the need for operators to master complex software maneuvers.
3Ease of operation
If manual mounting procedures are used, then models can be positioned in virtual articulators, but the process lacks precision in relating models to anatomical points
Solution Approach 1:
The horizontal rods feature locally differentiated zones with distinct functions: fixed anterior parts for stable reference, calibrated middle sections for precise measurement, and extendable posterior parts for adaptation. Each section possesses specific geometric characteristics (grooves, markers, adjustment mechanisms) tailored to its functional requirement, enabling the device to simultaneously provide both operational simplicity and high measurement precision for anatomical point alignment.
