A natural replicate of autologous bone, Gen-Os® conserves the same intimate structures1 (matrix and porous form) and presents a highly osteoconductive properties2. It is biocompatible and bioavailable, as recognized by tests made according to the ISO 10993 method conducted at Eurofins Biolab. Gen-Os® is gradually resorbable and provides support in bone neoformation helping to preserve the original graft shape and volume (osteoconductive property)3,4. Moreover, thanks to its collagen content, the product facilitates blood clotting and the subsequent invasion of repairing and regenerative cells, favouring restitutio ad integrum of missing bone. Because of its marked hydrophilia5, it can function as a carrier for selected medications and drugs6.
Gen-Os® must always be hydrated and thoroughly mixed with a few drops of sterile physiological solution to activate its collagen matrix and to enhance its adhesivity; it can also be mixed with patient's blood. If necessary it can as well be mixed with the drug selected for surgery.
Gen-Os®, a cortico-cancellous bone mix, has been the first product developed with the Tecnoss® innovative biotechnology and, due to its universal use, still is today the most demanded from the market. Gen-Os® has been successfully used and documented for alveolar ridge preservation7 in combination withEvolution membranes: the application of this biomaterial limits significantly the alveolar ridge width reduction that would naturally occur with spontaneous healing, preserving thus the alveolar ridge volume and allowing a correct second stage implant placement8. Gen-Os® is also indicated for lateral access maxillary sinus lift4,9 and dehiscence regeneration10, always in association with Evolution membranes. Ongoing studies are also proving its effectiveness in periodontal regeneration of deep intrabony defects. Due to its collagen content, once hydrated Gen-Os® becomes very sticky and hydrophylic5: it combines therefore extremely well with blood and is very stable once applied into the grafting site. Its cortico-cancellous composition allows a progressive resorption of osteoclastic type, with in parallel a similar rate of new bone formation2: these unique properties allow a very good graft volume preservation, a healthy new bony tissue and ultimately, a successful implant rehabilitation.
Gen-Os® expands up to 50% in volume after hydration with sterile saline: hydrated collagen contained in each granule also increases sensibly the biomaterial adhesivity.
