|March 13, 2025
Summary
This study details using CAD/CAM technology for dental veneers to close gaps between front teeth. This digital workflow ensured a minimally invasive approach, restoring the patient's smile aesthetics effectively.
Area of Science:
- Dentistry
- Digital Dentistry
- Prosthodontics
Background:
- Anterior diastemas can impact smile aesthetics and patient confidence.
- Minimally invasive treatment options are increasingly preferred in restorative dentistry.
Purpose of the Study:
- To describe the procedural sequence for anterior diastema closure using lithium disilicate veneers.
- To highlight the application of a hybrid digital workflow in achieving esthetic rehabilitation.
Main Methods:
- A 42-year-old female patient with a maxillary central incisor diastema was treated.
- A hybrid digital workflow involving provisional resin veneers (digital smile design) and CAD/CAM fabricated lithium disilicate veneers was employed.
- Minimally invasive preparations and bonding with preheated composite resin were performed.
Main Results:
- The digital planning and provisional veneers facilitated precise, minimally invasive enamel preparation.
- Thin, laminated lithium disilicate veneers were successfully fabricated and bonded.
- The treatment effectively restored the esthetic harmony of the patient's smile.
Conclusions:
- A hybrid digital workflow integrating CAD/CAM technology and provisional restorations is effective for anterior diastema closure.
- Minimally invasive preparations are achievable with digital planning, allowing for the placement of thin, esthetic veneers.
- This approach offers a predictable and successful method for improving smile aesthetics.
