High porosity and early remodeling improve clinical performance

The high porosity of THE Graft means a quicker absorption of fluids (e.g; blood) in comparison with DBBM. This not only facilitates the application of the material but also leads to early remodelling and improved clinical performance.

High level of porosity was demonstrated with particle pore structure test, particle size distribution test and total porosity tests.

• Macropores (diameter > 100μm), are necessary to form blood vessels and induce both bone growth and reorganization around the graft material.
• Micropores (diameter <10 μm), are required for the penetration of body fluids, ion transportation, the attachment of osteoblasts, and the precipitation of newly formed HA.
• Nanopores are characterized by dimension of less than 100 nanometers pores size between grains. Nano-porosity increases bone graft permeability to the physiological fluids and cells adhesion.
