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
