Summary
This study presents a digital workflow for fabricating occlusal splints, offering a predictable and time-efficient alternative to traditional methods. While cost-effective, the digital approach shows weaker retention compared to conventional techniques.
Area of Science:
- Dentistry
- Digital Fabrication
- Prosthodontics
Background:
- Traditional fabrication of occlusal splints is time-consuming and may lack predictability.
- Advancements in digital technology offer potential improvements in dental workflows.
Purpose of the Study:
- To describe a digital workflow for fabricating intraoral occlusal splints.
- To evaluate the efficiency, predictability, and material properties of this digital method.
Main Methods:
- A digital workflow encompassing registration, laboratory planning, and 3D printing was employed.
- Key steps included digital impressions, centric relation determination, and digital facebow measurements.
Main Results:
- The digital workflow demonstrated lower average costs and significant time savings compared to conventional methods.
- Fabrication was more predictable, but the printed material exhibited fragility and weaker retention.
Conclusions:
- The digital fabrication method is time-efficient and suitable for laboratory or chairside use.
- While applicable to daily practice, the limitations of material rigidity and retention require consideration.
