OXINIUM IMPLANT
(OXIDISED ZIRCONIA)
SMITH & NEPHEW(COMPANY)
After paralyzed technology
oxinium alloy + highly crosslinked polyethelyne.
Hip & knee replacement.
Typically made from both ceramic & metal
Properties:
strentgh
Durability
Biocompatibility
corrosion rate
OXINIUM
Made from specialized zirconium.
Biocompatible (similar to titanium used in industry)
the unique attribute
Enhance ability to function in implant technology.
eg:
Zr+O →ZrO2
Properties
Hard
resistance to abrasion& corrosion
used in high technology processing
Step on creating ZrO2
Collect Zr from rich sand
Chemical process to remove silicates
Pure Zr metal
Alloy comprised 97.5% pure Zr
Strong & broad bar stack used to make knee & hip implant.
PROCESS WORK
Use machine to grind & polish to refine the implant component until meet specification requirement.
