The choice between milled and 3D-printed splints depends on the clinical indication, required accuracy, and material properties needed.
Milled Splints
- Material: PMMA discs with certified biocompatibility
- Accuracy: 25-50 microns (excellent)
- Surface finish: Smooth, requires minimal polishing
- Best for: Hard occlusal splints requiring precise occlusal contacts
3D-Printed Splints
- Material: Light-cured resins (various durometers)
- Accuracy: 50-100 microns (acceptable)
- Surface: May require more post-processing
- Best for: Soft splints, night guards, sports mouthguards, try-in prototypes
For hard occlusal splints, milling provides superior accuracy. For soft splints and cost-sensitive applications, 3D printing is the better choice.
