Bio-inert Scaffold


     Natural Trabecular Bone                                Bio2 Inert Scaffold

Bio2’s bio-inert scaffold improves on existing porous metals in market in three ways:

  • Engineered pore structure to enhance cell proliferation and vascularization
  • Mechanical properties that facilitate tissue in-growth while minimizing stress shielding of the new tissue.
  • Lower cost manufacturing process
Biomaterials have both biological and mechanical responses which are important to healthy tissue in-growth. The greater the biological response, the more likely healthy tissue will regenerate. Stress and strain is equally important to healthy tissue growth. Traditional load bearing materials such as dense metals and ceramics shield the effected tissue from stress and strain. Bio2 inert scaffolds have the promise of less stress shielding while still being load bearing.

The chart below demonstrates Bio2’s ability to vary the mechanical properties of its inert materials, in this case alumina, at high porosities. This example changes the CLM bonding phase from hydroxyapatite (HAP) to alumina, resulting in a higher compressive strength and e-modulus.
