SICAT function: anatomical real-dynamic articulation by merging cone beam computed tomography and jaw motion tracking...

Area of Science:

• Dentistry
• Biomedical Engineering
• Medical Imaging

Background:

• Diagnostic imaging and jaw motion tracking are crucial for assessing stomatognathic system function and planning complex dental restorations.
• These technologies have historically been used independently, limiting comprehensive analysis.
• Integrating these modalities offers potential for more accurate patient-specific assessments.

Purpose of the Study:

• To introduce SICAT Function, a novel software application that merges 3D cone beam computed tomography (CBCT) and electronic jaw motion tracking (JMT) data.
• To demonstrate the software's capability to create a precise, real-dynamic rendering of jaw movement.
• To highlight the software's utility in measuring changes in the temporomandibular joint space during function.

Main Methods:

• Development and application of SICAT Function software.
• Directly combining and merging 3D CBCT data with electronic JMT data.
• Integration of digital impressions from intraoral scanners for enhanced visualization.
• Measurement and display of temporomandibular joint space changes at defined positions and during movements.

Main Results:

• SICAT Function successfully integrates CBCT and JMT data, providing an anatomically precise and dynamically accurate representation of jaw function.
• The software allows for direct measurement and display of joint space changes.
• Patient-specific assessment of condylar positions is achieved using a single CBCT scan, with other positions derived through correlation.

Conclusions:

• The integration of CBCT and JMT data via SICAT Function offers a powerful tool for comprehensive evaluation of the stomatognathic system.
• This approach facilitates improved planning and execution of complex prosthetic restorations.
• The software enhances the understanding of temporomandibular joint dynamics and spatial relationships.
