PEEK
PEEK (Polyether Ether Ketone)
ISO 10993
PEEK is a high-strength, thermostable, high-performance plastic. Thanks to its physical properties, which are comparable to those of cortical bone in humans, PEEK is the type of plastic most frequently used in orthopedics.
Sterelization
Steam sterilization at 134°C (273.2°F) EN 285 / ANSIA / AAMI / ISO 11134 – 1993
Advantages
-Bone-like modulus helps minimize stress shielding and stimulate bone healing
-No increase in thermal sensitivity and no need for microfixation plates
-Optimal protective function for patients
-Excellent biocompatibility
-Three-dimensional bone replacement
-Bio inert, radiotransparent and non-magnetic
-Low artifact formation in X-rays
Limitations
-Not osteoconductive
Ti-6A-4V-ELI
Aleación de Titanio; Ti-6A-4V Grado 23
ASTM F-136-02a
Completely free surfaces can be produced without tools or devices. There are previously unprecedented options for surface design. Reshaping processes are no longer required.
Sterelization
Steam sterilization a 134°C (273.2°F) / EN 285 / ANSIA / AAMI / ISO 11134 – 1993
Advantages
