Biomaterials Product news 2021 | 3 Safety standards and material properties Both the product and the production process comply with the required safety standards and requirements of the German and the EU regulations and the as well as the safety regulations required for xenogenic processing if applicable, including EN ISO 22442-1, EN ISO 22442-2 and EN ISO 22442-3. Properties of the bone graft substitutes CeraOss® (bovine) SynMax® (synthetic) Resorption rate Very low due to highly crystalline natural hydroxyapatite (HA) structure Medium due to synthetic HA and β-TCP (β-tricalciumphosphat) structure Volume stability at the grafting site Very high due to only superficial degradation Medium due to bi-phasic resorption rate Regenerative mechanism Osseous cellular integration Controlled cellular resorption Hydrophilicity High level High level Macroscopic structure Human-like bone structure with three-dimensional pore-network Foam-like structure Particle structure and surface Highly porous structure and rough surface Highly porous structure and rough surface Sterilization Sterilized using irradiation Shelf life 3 years 5 years Argonaut® (porcine) PermaPro® (synthetic) Origin Porcine pericardium, pure collagen matrix 100 % synthetic PTFE barrier membrane Crosslinked – Sterilization Ethylene oxide gas treatment Resorption 12–28 weeks Non-resorbable Thickness ~0.15 mm ~0.08 mm Shelf life 3 years 5 years Properties of the barrier membranes
