Millable Dental PEEK Discs, 4-5.6GPa Flexural Modulus,
Natural/White/Red Options
Designed for permanent implant prosthetics, these medical-grade
PEEK discs deliver bone-like elasticity (4-5.6GPa modulus) and >160MPa bending strength – enabling metal-free solutions for high-stress dental
applications. The semi-crystalline thermoplastic retains
dimensional integrity at 260°C, ensuring sub-50μm accuracy in
CAD/CAM workflows.
Revolutionary Biomechanical Properties
Cortical Bone-Matched Stiffness: 4.0-5.6GPa modulus eliminates stress shielding
Fatigue Resistance: 160MPa+ flexural strength supports multi-unit bridges
Bioinert Surface: ISO 10993-certified, inhibits bacterial colonization
Radiolucency: Zero imaging artifacts in CT/MRI scans
