Summary
This study introduces a digital method for creating occlusal splints, reducing variability and improving fit. This computer-aided design and manufacturing process ensures smoother surfaces and faster clinical placement.
Area of Science:
- Biomaterials Science
- Dental Technology
- Computer-Aided Design
Background:
- Traditional occlusal splint fabrication methods exhibit inherent variability.
- This variability can lead to suboptimal fit and increased chair time for adjustments.
Purpose of the Study:
- To develop and describe a computer-based process for designing and producing occlusal splints.
- To eliminate variability associated with conventional splint fabrication.
Main Methods:
- Laser scanning of stone casts.
- Custom software for digital articulation and splint design (flat-plane and full-coverage with guidance ramps).
- Milling of acrylic material over stone casts for splint production.
Main Results:
- The digital process offers quantitative control over articulation and splint design.
- Fabricated splints feature continuously smooth occlusal surfaces.
- Digital splints minimize intraoral equilibration, reducing average placement time.
Conclusions:
- Computer-based design and production offer a reproducible and efficient method for occlusal splint fabrication.
- This digital workflow enhances precision and clinical efficiency compared to traditional methods.
