Recommended Applications

Monolayer PMMA discs are suitable for dental laboratories producing temporary crowns, bridges, implant provisional restorations, full-arch temporary cases, diagnostic prototypes, and try-in restorations.

The single-layer color structure makes them a practical choice when strength, shade consistency, and cost efficiency are more important than natural gradient esthetics.

  • Temporary crowns and bridges
  • Implant provisional restorations
  • Full-arch temporary restorations
  • Diagnostic mock-ups and evaluation models
  • Try-in restorations for esthetic evaluation

Recommended Milling Workflow

  1. Select the correct system, shade, and thickness
  2. Design the temporary restoration in CAD software
  3. Mill using PMMA-compatible burs and the recommended milling parameters
  4. Remove connectors and finish margins carefully
  5. Finish and polish progressively to achieve a smooth surface
  6. Verify fit, occlusion, and shade before delivery

Monolayer PMMA vs. Multilayer PMMA

Compare Monolayer and Multilayer PMMA by shade structure, milling orientation, esthetic requirements, and case type.

  • Monolayer PMMA

    • Single uniform color
    • No milling orientation requirement
    • Best for strength, consistency, and cost efficiency

  • Multilayer PMMA

    • 5-layer shade gradient
    • Requires correct milling orientation
    • Best for enhanced esthetics and natural-looking temporaries

What is PMMA, and why is it used for temporary restorations?

PMMA is a CAD/CAM acrylic material commonly used for temporary crowns, bridges, provisional restorations, try-ins, and diagnostic cases. It is easy to mill, polish, and adjust for dental lab workflows.

What restorations can Monolayer PMMA Discs be used for?

They are suitable for temporary crowns and bridges, implant provisional restorations, full-arch temporary restorations, diagnostic prototypes, and try-in restorations.

How long can PMMA temporary restorations last?

With proper care, PMMA temporary restorations can last 6-12 months. This makes them ideal for extended temporary periods such as implant healing, orthodontic treatment, or while waiting for final restorations.

What makes OnePro Monolayer PMMA different from other PMMA discs?

Our Monolayer PMMA features ≥120 MPa flexural strength (vs industry average 90-110 MPa), <1% residual monomer (vs <2% average), and superior color stability. This means stronger, more biocompatible, and longer-lasting temporary restorations.

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

98mm discs are designed for open-system milling holders, while 95mm discs are designed for Zirkonzahn-style milling systems. Please confirm your machine and holder before ordering.

Does PMMA shrink during processing?

No. PMMA does not require sintering and does not shrink like zirconia. The restoration is milled close to its final size.

What burs are recommended for milling PMMA?

PMMA-compatible dental milling burs are recommended. Worn or unsuitable burs may affect surface quality, margin accuracy, and polishing results.
