Milled PMMA Bite Splints
Milled PMMA splints are rigid occlusal guards digitally designed and milled from a solid PMMA puck. They offer a precise fit, smooth occlusion, and long-term strength compared to traditional thermoformed guards. These splints are optically clear, highly polishable, and ideal for patients who need a stable appliance that seats cleanly and holds up over time.
Available as:
- Upper arch
- Lower arch
- Dual Arch (rare)
