Dental splint milling workflow using transparent Clear PMMA disc

Recommended Milling Workflow

  1. Select the correct system and thickness for the appliance
  2. Design the splint, guide, or functional appliance in CAD software
  3. Mill with sharp PMMA-compatible burs and a suitable milling strategy
  4. Remove connectors carefully and smooth the margins
  5. Progress through fine finishing tools to remove milling marks
  6. Polish progressively to improve surface smoothness and transparency
  7. Clean the appliance thoroughly and inspect the fit and contact areas
  8. Verify transparency, surface quality, and final adaptation before delivery

Clear PMMA vs. Tooth-Colored PMMA

Choose the material based on appliance visibility, restoration type, and esthetic requirements.

  • Clear PMMA

    • Transparent material for visible fit and contact inspection
    • Best for splints, night guards, guides, and functional appliances
    • Requires careful finishing and polishing for maximum clarity

  • Tooth-Colored PMMA

    • Vita-shade material for temporary crowns and bridge
    • Best for provisional restorations and diagnostic try-ins
    • Available in Monolayer and Multilayer shade structures

What is Clear PMMA used for?

Clear PMMA is commonly used for CAD/CAM occlusal splints, night guards, surgical guides, bite plates, functional appliances, and diagnostic appliances that require transparency and reliable dimensional stability.

Is Clear PMMA suitable for night guards?

Yes. Clear PMMA can be used for CAD/CAM night guards and bruxism appliances. The final appliance design, thickness, and clinical suitability should be determined by the dental professional.

Can Clear PMMA be used for surgical guides?

Clear PMMA can be used for selected CAD/CAM surgical guide applications where transparency, dimensional stability, and visibility are required. The guide design and clinical protocol should be verified by the dental professional.

Does Clear PMMA require sintering or crystallization?

No. Clear PMMA is milled directly and does not require sintering or crystallization. After milling, the appliance requires finishing, polishing, cleaning, and final fit verification.

How can maximum transparency be achieved?

Maximum transparency depends on careful finishing and progressive polishing. Milling marks should be removed with fine finishing tools before polishing the surface to a smooth, high-gloss finish.

Can Clear PMMA be milled wet or dry?

Clear PMMA may be processed using an appropriate wet or dry milling strategy, depending on the milling machine, bur system, and CAM recommendations. Sharp PMMA-compatible burs should be used.

What is the difference between 98mm Open System and 95mm Zirkonzahn?

The 98mm version is designed for standard open-system disc holders, while the 95mm version is designed for Zirkonzahn-style milling systems. Always confirm the disc holder format before ordering.

What thickness should I choose?

The suitable thickness depends on the appliance design, vertical dimension, nesting requirements, and milling system. Thinner discs are commonly selected for lower-profile cases, while thicker discs provide more room for larger appliances and complex designs.
