Summary
A new method creates universal 3D colorized digital dental models using intra-oral scans and photography. This enhances visual realism and improves dentist-patient communication for aesthetic dental treatments.
Area of Science:
- Digital dentistry
- Computer-aided technology in dentistry
Background:
- Current 3D digital dental models lack realistic color representation.
- Improved visual effects are needed for common 3D software editing.
Purpose of the Study:
- To develop a universal 3D colorized digital dental model construction method.
- To enhance the visual effect of digital dental models in 3D software.
Main Methods:
- Intra-oral scanning (3Shape TRIOS) for 3D model morphology.
- Digital photography (DSLR) for capturing tooth and gingiva color data.
- Projecting and blending photographs onto 3D models in Geomagic Studio for colorization.
Main Results:
- Successfully constructed universal 3D colorized digital dental models with improved color simulation.
- Demonstrated clinical application in 3D smile design for aesthetic rehabilitation.
- Enhanced patient understanding of digital aesthetic designs and virtual prosthetic outcomes.
Conclusions:
- 3D colorized digital dental models can be effectively created using 3D scanning and digital photography.
- Enhanced visual perception improves dentist-patient communication in clinical practice.
- This method offers better color simulation for digital dental models.
