Vitoss BA
Bioactive Bone Graft Substitute
A synthetic bone graft with bioactive glass that has a unique porosity, structure, and chemistry to help drive 3D regeneration of bone
Vitoss BA Bioactive Bone Graft Substitute
Literature has shown that bioactive glass exhibits good bonding-to-bone properties in animal models.1-3 Upon implantation, the ionic constituents (Silicon, Sodium, and Calcium) of bioactive glass are released into the surrounding environment and react with bodily fluids.4-7 This reaction produces the deposition of a thin layer of physiologic calcium phosphate at its surface, favorable for osteoblast attachment.8 This is commonly referred to as a bioactive effect, and may lead to the bonding of new bone to the scaffold.1-3,6,9-11 Vitoss BA is a highly porous calcium-phosphate (up to 90% porous)12 containing bioactive glass that is stable at physiological pH13 and resorbs during the natural remodeling process of bone.14
The addition of bioactive glass helps create a surface favorable for osteoblast attachment1-3,6,9-11
Vitoss BA Foam Pack is stable in a fluid environment, can soak and hold bone marrow, and is moldable
Vitoss BA Foam Strip is flexible when wet, can soak and hold bone marrow, and is compression resistant and easy to cut
Note: In-vitro bioactivity testing has not been evaluated in human clinical trials.
