Vitoss - Technical Specifications

Vitoss guides the three-dimensional regeneration of bone.	Vitoss resembles the multidirectional interconnected porosity of human cancellous bone.
Nanoparticle structure permits cell-mediated resorption as new bone is formed throughout the Vitoss Scaffold.	Microporous structure facilitates capillary wicking of bone marrow and provides pathways for fluid, nutrient, and oxygen transport to nourish new bone.

Vitoss Bone Graft Substitute:

Beta-tricalcium phosphate (β-TCP), a natural material consisting of calcium and phosphorous - the primary constituents of bone
Resorbable, concurrent with the formation of bone
Excellent hydrophilic properties; readily wicks and absorbs blood, cells, marrow and nutrients
Vitoss morsels are 100% β-TCP, Foam products are 80% β-TCP and 20% bovine Type I collagen

Multi-directional, open and interconnected porosity that mimics the structure of human cancellous bone
Accommodates bone growth in the center and throughout the implant (3D bone regeneration as opposed to creeping substitution)
Nanoparticle construction allows for cell-mediated resorption

88-92% porous
Pore sizes range from 1-1000 µm in diameter
Macroporosity (100 µm – 1000 µm) allows new bone to grow in apposition to the implant surfaces throughout the implant
Interconnecting meso (100 µm) and microporosity (< 10 µm) permit fluid communication and nutrient transport to support bone re-growth throughout the implant
Porosity and hydrophilicity facilitate fast wicking and absorption of blood, marrow and nutrients into the center of the implant
