composição vítrea bioativa e seu uso para regeneração óssea. a presente invenção refere-se a uma composição vítrea bioativa que compreende óxido de nióbio e seu uso para regeneração óssea. a presente invenção se insere no campo da química de materiais compreendendo scaffolds para engenharia tecidual óssea, medicina osteoregenerativa e têm a sua aplicação direcionada no preenchimento de defeitos ósseos causados por doenças ou acidentes. The present invention relates to a bioactive vitreous composition comprising niobium oxide, and to the use thereof for bone regeneration. The present invention pertains to the field of the chemistry of scaffold-comprising materials for bone tissue engineering and osteoregenerative medicine, and is aimed at correcting bone defects caused by diseases or accidents. The present application relates to a bioactive vitreous composition (bioglass) comprising from 40 to 55 mol% SiO2, from 23 to 33 mol% CaO, from 20 to 30 mol% Na2O, from 0.001 to 5 mol% P2O5 and from 0.001 to 5 mol% Nb2O5. This composition has medical and odontological uses as bone filling material, as scaffold for bone tissue engineering, for bioactive coatings and for the treatment of dentin hypersensitivity.
