Bone regeneration membrane and method for forming a bone regeneration membrane

摘要

Bone regeneration membrane (1) comprising: - a dense layer (2) made of resorbable polymer, said dense layer (2) first and second opposite surfaces 5 and being adapted to form a barrier for cells and soft tissue, - one nanofibrillar layer (3) made of resorbable and bonded to the first surface of the dense layer (2) polymer, said nanofibrillar layer fibers having a diameter of nanometric size comprising said interlocking to present an average pore size greater than 10 fibers being microns to allow cell permeability and regeneration of bone tissue, having the nanofibrillar layer (3) a permeability K 0.4 x 10-9 m2 and 11 x 10-9 m2, preferably between 1 x 10-9 m2 and 4 x 10 -9 m2, in particular substantially 2 x 10-9 m2 of.
