Design for functional occlusal surface of CAD/CAM crown using VR articulator.

Area of Science:

• Dental Technology
• Biomedical Engineering
• Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM)

Background:

• Traditional methods for designing occlusal surfaces can be time-consuming and may not fully replicate natural jaw movements.
• Accurate functional occlusion is critical for the longevity and performance of dental restorations.

Purpose of the Study:

• To introduce and evaluate a novel CAD/CAM system that utilizes a virtual reality (VR) articulator for designing functional occlusal surfaces.
• To compare the efficacy of this new approach with conventional methods for occlusal surface design.

Main Methods:

• Development of a new CAD/CAM system incorporating a VR articulator to simulate lateral excursions.
• Design of functional occlusal surfaces using the VR articulator system.
• Comparison of the resultant occlusal surfaces with those produced by conventional methods.

Main Results:

• A novel CAD/CAM system capable of rendering functional occlusal surfaces via a VR articulator was successfully developed.
• The marginal fit and occlusion of the CAD/CAM crowns met clinical requirements.
• The new system demonstrated a viable method for creating functional occlusal surfaces.

Conclusions:

• The developed CAD/CAM system utilizing a VR articulator offers a promising approach for designing functional occlusal surfaces.
• The system's ability to ensure adequate marginal fit and occlusion supports its potential clinical application.
• This technology represents an advancement in digital dentistry for creating accurate dental restorations.
