Virtual Dental Patient Model for Jaw Motion Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental imaging systems fail to accurately represent the complex motion of the lower jaw relative to the upper jaw, lacking the capability to model its lateral and protrusive movements effectively.
Innovation Solution
A software and hardware system that processes clinical records, including analog and digital data, to create a virtual dental patient model by aligning and merging scan data sets, calculating helical axis parameters, and rendering accurate jaw motion using 3D rendering algorithms and computer optimization routines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional scanning systems are used to capture dental data, then basic dental imaging is possible, but the complex motion of the lower jaw relative to the upper jaw cannot be accurately represented
Solution Approach 1:
The system segments the jaw motion modeling into separate helical axis parameters (rotation and translation components) that can be independently calculated and applied. This allows complex jaw motion to be broken down into manageable transformations that can be accurately represented in the virtual patient model.
Solution Approach 2:
The system transitions from two-dimensional clinical records to three-dimensional virtual models by calculating helical axis parameters that describe motion in multiple dimensions. This enables accurate representation of lateral and protrusive jaw movements that cannot be captured in traditional 2D imaging.
2Reliability
If clinical records are scanned and processed to create virtual patient models, then diagnostic capabilities are improved, but the system complexity increases
Solution Approach 1:
The system creates a virtual copy of the patient's dental anatomy and motion characteristics from scanned clinical records. This virtual patient model preserves all essential diagnostic information while eliminating the need for physical examination equipment and reducing diagnostic complexity.
Solution Approach 2:
The system replaces physical mechanical scanning and measurement processes with digital image processing and computer optimization routines. This substitution reduces physical wear and complexity while improving the reliability and consistency of diagnostic measurements.
3Measurement precision
If physical examination methods are used to examine jaw motion, then direct observation is possible, but physical discomfort is caused to the patient
Solution Approach 1:
The system creates a virtual replica of the patient's jaw motion from scanned clinical records, eliminating the need for physical examination procedures. The virtual patient model can be examined repeatedly without causing any physical discomfort or risk to the actual patient.
Solution Approach 2:
The virtual patient model serves as an intermediary between the diagnostician and the actual patient. This intermediary allows functional examination of jaw motion to be performed repeatedly and accurately without directly contacting or discomforting the patient.

AI summary
Systems and methods read clinical data records to create and three-dimensional images representing a virtual dental patient. The images can be used to assess the current dental health of a patient. In particular the systems and methods create accurate, three-dimensional virtual renditions of dental patients, compare the virtual renditions with other virtual renditions, and create computer databases of the renditions from which population statistics are calculated for parameters measured on the renditions. By comparing a particular patient rendition to the population statistics a report is produced that aids in the diagnosis of the patient's current dental health.
