Characteristics:   obtained from mesenchymal tissue (heterologous pericardium) the Evolution membrane is completely resorbable.  Its structure is  made of dense collagen fibers of high consistency and of extraordinary resistance that offer the specialist surgeon:

• The maximum adaptability to bone tissue and soft tissues.
• An easy and secure suturability to nearby tissues.
• The best membrane/bone and membrane/periosteum interface.
• Stability and prolonged protection of the underlying graft.

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.

Handling:  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.  NB:  if Evolution, for any reason, shows dehiscences (for example in the secondary tearing of flaps) it must absolutely not be removed, its consistency allows a complete second intention healing of the wound, due to physiological covering of the flaps.

Clinical applications: 

Oral surgery and taumatology: the standard model is always recommended in case of large regeneration with risks of exposure.
Implantology:  ideal for covering antrostomy and for protection of two wall defects graft.
Periodontology: protection of grafted intrabony defects when flaps suture presents risks of exposure (fine model), space making in gingival recessions (x-fine model).
Besides an eutrophic effect, Evolution membranes provide grafting site stabilization as well as long lasting protection against external agents.
