Characteristics
Obtained from heterologous mesenchymal tissue, the Evolution membrane is gradually resorbable(1). 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 graft
• clot stabilization and isolation(2)
Handling
The membrane can be shaped with sterile scissors until the desired size is reached; unless the grafting site is already bleeding, the membrane should be rehydrated with lukewarm physiological solution. Once it acquires the desired plasticity, it must be adapted to the grafting site.
NB: 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 healing(3-5).
Clinical indications
Evolution is obtained from heterologous mesenchymal tissue and is completely resorbable. Experimental studies have shown histological evidence of the prolonged barrier effect of this membrane, which lasts at least eight weeks(1), protecting the graft from external agents. This property is particularly important in case of flapless regeneration(3) of large posterior sockets(5): in these cases, the standard model has proved to be the most effective. In lateral access sinus lift, Evolution membranes have been documented for antrostomy coverage (standard model)(6,7) and for protection of the sinus membrane from cutting risk due to graft pressure (fine model)(8). Evolution can be used to protect peri-implant regenerations(9) and periodontal grafts(10). Furthermore, Evolution fine has been successfully used to protect Sp-Block in vertical augmentation with the inlay technique(11).

The above clinical information is based on the experience of expert surgeons.
