BioSphere - Model Putty - Bioactive Bone Graft

Bone graft composed of bioactive glass

• Bioactive glass forms a bone-like mineral layer on its surface that promotes bone formation and attachment [1]
• Bioactive glass dissolution ions stimulate cells involved in bone healing [2]

Unique spherical particle shape

• Spherical particles provide uniform resorption and ion release
• 3-D sphere packing provides an optimal porosity for bone formation throughout implant site

Bimodal size particle range

• Small spheres (10%) provide fast resorbing particles that starts the bone healing process with a quick release of dissolution ions
• Large spheres (90%) provide slower resorbing particles that provides a scaffold for bone formation and longer term ion release

Resorbable phospholipid carrier

• Allows BioSphere Putty to have a high bioactive glass particle content
• Creates a moldable putty with excellent handling and cohesiveness
• Naturally occurring phospholipids are absorbed by the body and used by local cells

Highest bioactive glass content on the market (80% w/w)

• Provides complete filling of a bone defect with bioactive glass particles
• Results in better particle contact with the edges of the bone defect which promotes faster healing
• Minimizes particle settling after carrier resorption

Excellent handling, resistance to irrigation, and graft placement

• Putty can be easily customized to fit the surgical site
• Does not wash away with exposure to blood or irrigation fluid
• Designed to be mixed with particulate autograft
