Mandibular Movement Simulation Using Medical Image Models

The patent replaces the mechanical articulator system with a computer-based simulation system that uses digital models, imaging data, and software algorithms to simulate mandibular movements. This substitution eliminates the mechanical constraints of physical articulators while achieving higher accuracy through computational methods that can process complex anatomical variations and movement patterns without physical simplification.

The patent creates digital copies of the patient's actual mandibular anatomy through medical imaging (CT, MRI) and uses these digital replicas to simulate movements. This copying approach allows the simulation to precisely replicate individual anatomical characteristics without the loss of detail that occurs when using simplified mechanical articulators, thereby maintaining high accuracy while avoiding complex mechanical manufacturing.

The patent employs dynamic simulation methods that allow the digital model to adapt to various movement types and clinical scenarios. The computer-based system can dynamically adjust simulation parameters, apply different force vectors, and model complex muscle interactions without requiring additional physical components. This dynamic approach enables the simulation of diverse mandibular movements including asymmetrical patterns, pathological conditions, and multiple functional states within a single versatile system.

The computer-based simulation system serves multiple functions: it can analyze normal and pathological movements, plan orthognathic surgery, design dentures, evaluate TMJ disorders, and simulate various muscle force conditions. This multi-functionality is achieved through software modules that can be configured for different clinical applications without requiring separate physical devices, thereby providing extensive movement simulation capability with a single unified system.

The patent applies local quality by customizing the digital model to reflect each patient's specific anatomical characteristics extracted from their medical images. The simulation system processes individual patient data including asymmetrical jaw joint positions, unique tooth arrangements, and specific muscle attachment points, creating a tailored digital replica for each case. This approach maintains standardization in the overall simulation workflow while adapting local anatomical details to match the individual patient's unique features.

The system automatically adjusts simulation parameters based on each patient's extracted anatomical data, including condyle positions, mandibular geometry, and muscle force vectors. Rather than using fixed universal values, the computer algorithm modifies these parameters to match the individual patient's anatomy, enabling accurate simulation of asymmetrical and unusual cases while maintaining a standardized computational framework that can handle diverse parameter sets.
