The Graft Material
StemVie™ Bone Graft Substitute is a biphasic ceramic composed of 60% Hydroxyapatite (HA) and 40% beta-Tricalcium Phosphate (β-TCP) and presents a global interconnected porosity of 70% with:

• 2/3 macropores (300-600µm)
• 1/3 micropores (<10µm)

BioActive and Osteoconductive
Specific HA/TCP ratio and global porosity provides:

• Short term dissolution/precipitation process into micropores
  
• New interface recognized by the cells as the host bone
  
• Balance between resorption and bone substitution
  
• Macropores guide bony cells into the depths of the StemVie™ Graft.
