Mutilayer dental pmma disc CAD CAM Dental PMMA Blank
Mutilayer dental pmma disc CAD CAM Dental PMMA Blank is made of multi-layer PMMA, which can meet the requirements of high strength and high transparency in dental restoration. It has extremely high processing accuracy and is one of the ideal materials for digital dentistry.
- Product Introduction
Products Description
Material purity and composition
Using medical-grade PMMA (polymethyl methacrylate) raw materials, the purity is ≥99.8%, in line with ISO 10993 biocompatibility certification and CE certification standards.
Impurity content <0.02%, heavy metal content <0.1ppm, ensuring clinical safety.
It is biocompatible and will not cause allergic reactions.
| Property | Value | Industry Comparison |
|---|---|---|
| Flexural Strength | ≥ 110 MPa | Higher than traditional PMMA (typically 80–90 MPa) |
| Vickers Hardness | ≥ 180 HV | Comparable to natural enamel hardness |
| Water Absorption Rate | ≤ 0.15% | Lower than the industry average of 0.2% |
| Heat Deflection Temperature | ≥ 90°C | Suitable for high-temperature sterilization environments |
*High bending strength reduces the risk of denture breakage, and low water absorption prevents material expansion and deformation
Fully compatible with mainstream CAD/CAM systems, supporting STL, IGES, and other standard file formats.
Cutting resistance: ≤ 3.2 N (Test condition: 24,000 rpm spindle speed, 0.1 mm/rev feed rate)
Tool life extended by 30% compared to conventional PMMA materials
This results in lower material waste and reduced maintenance costs for downstream processing equipment.
Dimensional Accuracy & Consistency
Disc diameter tolerance: ±0.1 mm
Thickness tolerance: ±0.05 mm
Flatness: ≤ 0.03 mm/m²
Translucency: Up to 92% at 450 nm wavelength, offering natural light transmission for lifelike esthetics.
Color Customization: Available in VITA 16 classic shades and optional fluorescent effects to meet diverse clinical and cosmetic demands.
Color Fastness: Achieves Grade ≥4 according to ISO 105-B02, ensuring long-lasting shade stability after staining.
Sterilization & Storage
Supports high-pressure steam sterilization (134°C, 20 minutes)
Compatible with ethylene oxide sterilization
Shelf life: Up to 3 years under optimal conditions (humidity < 60%, temperature 15–25°C)
