1. A bone regeneration membrane comprising:

  • a dense layer made of resorbable polymer, said dense layer having first and second opposite surfaces and being adapted to form a barrier to cells and soft tissues,a nanofibrillar layer made of resorbable polymer and attached to the first surface of the dense layer, said nanofibrillar layer comprising fibers having a diameter of nanometer size, said fibers being interlaced so as to present an average pore size greater than 10 μ

    m to allow cell permeability and bone tissue regeneration, the nanofibrillar layer having a permeability K between 0.4*10-9 m2 and 11*10-9 m2, preferably between 1*10-9 m2 and 4*10-9 m2, in particular substantially of 2*10-9 m2.
