- Open architecture with 70% porosity including varying pore sizes of 300, 500, and 700 microns that mimic cancellous bone allowing for a conducive environment for cellular activity.1,5,6,7
- Scaffolding structure provides additional surface area 2,3 and an elastic modulus similar to PEEK.8
- 7 micron surface texturing enhances the wicking nature9 and creates an environment for potential cellular adhesion.2,3,4
