Summary
This study introduces a digital method for reconstructing full denture occlusion using 3D scanning. This technique establishes a foundation for advanced digital analysis of complete denture occlusal relationships.
Area of Science:
- Dentistry
- Biomedical Engineering
- Digital Technology
Background:
- Accurate occlusal relationships are crucial for full denture function and patient comfort.
- Traditional methods for determining occlusal relationships can be time-consuming and lack precision.
Purpose of the Study:
- To investigate a novel digital method for locating and reconstructing the occlusal relationship of complete dentures.
- To establish a quantitative system for analyzing complete denture occlusion in centric occlusion.
Main Methods:
- Artificial teeth occlusal surfaces of ten complete dentures were scanned using a non-contact laser scanner.
- Three-dimensional (3D) reconstruction techniques were employed to analyze the occlusal surfaces.
- Six standard steel balls were used to determine the 3D positional relationship of the upper and lower dentures in centric occlusion.
Main Results:
- A preliminary 3D reconstruction and measuring system for complete denture occlusion was successfully established.
- The study demonstrated the feasibility of digitally capturing and reconstructing occlusal relationships.
Conclusions:
- A new system for quantitatively reconstructing the occlusal relationship of complete dentures in centric occlusion was developed.
- This digital approach provides a methodological foundation for future 3D research in complete denture occlusion.
