chronOS® Bone Graft Substitute(Trauma)

chronOS®Bone Graft Substitute (BGS) is a synthetic β-tricalcium phosphate bone void filler which is radiopaque, resorbable and osteoconductive.

Category:

Bone Minerals
chronOS® Bone Graft Substitute contains calcium and phosphorus, two of the main mineral constituents of bone.

REMODELING WITHIN 6 TO 18 MONTHS1, 2, 3
Osteoclasts resorb chronOS Bone Void Filler implants like natural bone.1

chronOS® Bone Graft Substitute

  1. Available as granules and preformed shapes
  2. ChronOS Bone Void Filler implants benefit from a compromise between porosity and mechanical stability4, 5
  3. The size of the macropores of chronOSBone Void Filler implants are distributed within a range of 100 to 500 μm which provides the scaffold for vascularization and migration of osteoclasts and osteoblasts.6
  4. Can be perfused with the patient’s own blood or bone marrow
  5. Can be used alone or mixed with autograft for large volume defects
  6. Due to the synthetic origin of chronOS bone void filler implants there is no risk of animal tissue prion related disease transmission to the patient due to chronOS.7, 8, 9
