Flexible PMMA Resin Disc 98mm for Open CAD/CAM Milling Systems

The Flexible PMMA Resin Disc for 98mm open milling systems is specially engineered for dental laboratories that require enhanced impact resistance and flexibility in temporary restorations. Unlike standard rigid PMMA discs, this flexible variant absorbs masticatory forces without fracturing, making it particularly valuable for bruxism patients and long-span provisional bridges. Its biocompatible, stain-resistant formulation ensures patient comfort and hygiene throughout the entire treatment period.

Key Features & Benefits

• Excellent Impact Resistance: Flexible PMMA matrix absorbs shock from heavy occlusal forces, significantly reducing the risk of fracture in temporary restorations compared to standard rigid PMMA.
• Superior Biocompatibility: Medical-grade PMMA formulation is safe for intraoral use with no irritation, allergic reactions, or unpleasant odor for patients.
• Low Water Absorption: Dense molecular structure minimizes water uptake, preventing dimensional changes and maintaining the precise fit of milled restorations over time.
• Stain Resistant: Smooth, high-density surface repels food pigments, coffee, tea, and other common staining agents, keeping provisionals looking fresh.
• Odor-Free Formulation: Unlike some PMMA materials, this disc produces no residual monomer smell, enhancing patient acceptance and comfort.
• Universal Open System Fit: Precision-machined 98mm diameter fits all standard open-architecture CAD/CAM milling units.

Frequently Asked Questions

How is flexible PMMA different from standard PMMA?

Flexible PMMA contains modified polymer chains that allow controlled bending under stress rather than cracking. This makes it ideal for patients with strong bite forces or parafunction habits like clenching and grinding.

Does the flexibility affect milling quality?

No. The disc maintains sufficient rigidity for precise dry milling on standard CAD/CAM machines. The flexibility becomes apparent only under functional loading forces after cementation in the oral environment.

Can I polish flexible PMMA to a high shine?

Yes, flexible PMMA polishes beautifully using standard PMMA polishing protocols. The high-density surface achieves an excellent gloss that is both aesthetically pleasing and resistant to plaque accumulation.

What bonding agents work with this material?

Standard temporary cement systems such as TempBond, RelyX Temp, or similar non-eugenol temporary cements are recommended. Avoid permanent cements to allow easy removal when the definitive restoration is ready.
