Flexible PMMA Resin Disc 89mm for Amann Girrbach Ceramill Systems

The Flexible PMMA Resin Disc for 89mm Amann Girrbach Ceramill milling machines delivers enhanced impact resistance specifically optimized for the Ceramill platform. This specialized disc produces temporary restorations that flex under heavy bite forces instead of fracturing, providing peace of mind for both dental laboratories and their clinical partners. The biocompatible, low-water-absorption formulation ensures dimensional stability and patient comfort throughout the provisional treatment phase, while the stain-resistant and odor-free properties enhance overall clinical performance.

Key Features & Benefits

• Excellent Biocompatibility: Medical-grade PMMA meets stringent biocompatibility standards for safe, extended intraoral contact without mucosal irritation or allergic sensitization.
• Enhanced Impact Resistance: Flexible polymer matrix prevents catastrophic fracture under parafunctional forces, making this disc the preferred choice for bruxism patients needing reliable temporaries.
• Low Water Absorption: High-density PMMA structure minimizes hygroscopic expansion, maintaining the original marginal fit and preventing secondary caries risk at the temporary-tooth interface.
• High-Density Construction: Compact molecular packing creates a non-porous disc surface that mills cleanly and polishes to a bacteria-resistant, aesthetically pleasing finish.
• Stain-Resistant & Safe: Hydrophobic surface chemistry actively repels food dyes, coffee, red wine, and other chromogens, keeping provisionals aesthetically clean between appointments.
• Completely Odor-Free: Zero residual monomer formulation eliminates unpleasant chemical smells during milling and ensures patient acceptance without taste or odor complaints.

Frequently Asked Questions

Is this disc compatible with all Ceramill machines?

Yes, this 89mm disc fits all Amann Girrbach Ceramill milling machines that accept the standard 89mm round disc format, including Ceramill Matron, Ceramill Matik, and Ceramill Motion 3.

How flexible is the finished restoration?

The flexibility is calibrated for dental function - the restoration maintains rigid shape during normal wear but flexes under excessive forces rather than fracturing. Patients will not perceive the flexibility during normal eating and speaking.

What is the shelf life of this PMMA disc?

When stored in original sealed packaging in a cool, dry location away from direct sunlight, the disc maintains its mechanical and aesthetic properties for up to 3 years from the manufacturing date.

Can I repair a flexible PMMA temporary if needed?

Yes, standard PMMA repair techniques work well. Light-cured flowable composite or self-curing acrylic repair materials bond effectively to the flexible PMMA surface for chairside or labside repairs.
