Summary
A virtual semi-adjustable articulator was developed for complete denture computer-aided design (CAD). This system simulates biting motions and performs virtual occlusal adjustments on digital denture models.
Area of Science:
- Dental prosthetics
- Computer-aided design (CAD)
- Biomechanics
Context:
- Traditional semi-adjustable articulators are essential for complete denture fabrication.
- Integrating virtual articulators into CAD systems offers advanced simulation capabilities.
- Digitalizing the process of occlusal analysis and adjustment is a growing trend in prosthodontics.
Purpose:
- To explore and develop a virtual semi-adjustable articulator for complete denture CAD.
- To simulate the biting motion of a complete denture digital model.
- To enable virtual occlusal adjustment within the CAD environment.
Summary:
- A virtual semi-adjustable articulator program was developed using Scoll language for a Complete Denture CAD System.
- The program successfully simulated 3D biting motion, detected occluding relations, and performed automatic occlusal adjustments on a digital denture model.
- This represents a technical advancement in applying virtual articulators to the CAD process for complete dentures.
Impact:
- Enables more accurate and efficient digital design of complete dentures.
- Facilitates virtual simulation and adjustment of occlusion, reducing the need for physical try-ins.
- Provides a foundation for further development of digital workflows in prosthodontic treatment planning.
