Obtained from mesenchymal tissue (heterologous pericardium) the Evolution membrane is completely resorbable1. Its structure is made of dense collagen fibers of high consistency and of extraordinary resistance that offer the specialist surgeon: - maximum adaptability to bone tissue and soft tissues - easy and secure suturability to nearby tissues - best membrane/bone and membrane/periosteum interface - stability and prolonged protection of the underlying graft2.
The membrane can be shaped with sterile scissors until the desired size is reached; it must then be rehydrated with lukewarm physiological solution. Once it acquires the desired plasticity, it must be adapted to the grafting site. N.B.: in case of accidental exposure, the dense collagenic matrix of Evolution protects the graft from infection; the membrane itself will also not be infected, allowing second intention healing3,4.
Oral surgery and traumatology: always recommended in case of large regenerations with risks of exposure.
