The biodegradable, radiopaque granules/blocks are resorbed in approximately 6-12 months when used in accordance with the device labelling. Biocomposites Tri-Calcium Phosphate Bone Graft Substitute is manufactured from medical grade Tri-Calcium Phosphate. Numerous bone graft operations are undertaken every year to repair bone defects caused by surgery, tumours, trauma, infections and other damage.
